CAUTION  
Before installation, careful consideration must be given to  
how the system will operate if connected to any other piece  
of mechanical equipment, i.e. a forced air furnace or air  
handler, operating at a higher static. After installation, the  
compatibility of the two pieces of equipment must be  
confirmed, by measuring the airflow’s of the Heat/Energy  
Recovery Ventilator (HRV/ERV), by using the balancing  
procedure in this manual.

ERV Quest ions & Answers  
What is the difference between an HRV  
and damp situation. In fact, about 2/3 of the energy  
used by the air conditioner system is to remove  
moisture. Therefore, when ventilating in the summer,  
less moisture brought into the home means less work  
for the air conditioner, and energy savings for you.  
and an ERV?  
The core in an HRV (Heat Recovery Ventilator)  
transfers heat from one air stream to the other. This is  
called sensible heat. The term ERV (Energy Recovery  
Ventilator) is usually used to describe a unit with an  
enthalpic core that transfers moisture as well as heat  
from one air stream to the other. This (moisture  
transfer) is called latent heat.  
During the winter, an ERV recovers some humidity  
from the exhaust air, reducing the need for humidification  
,
if the required ventilation rate would make the home  
too dry.  
Enthalpic - what does it mean?  
Enthalpy is the term used to describe the energy  
content of air. This energy is a combination of the  
sensible and latent heat. Therefore, a core which  
transfers energy is called an enthalpic core.  
What's the difference between this type of  
core and a rotary type?  
Here's a list of characteristics of the fixed plate core.  
1. No rotating parts, so maintenance is easy and the  
unit lasts a long time.  
2. It is very flexible in terms of installation.  
3. The core can easily be changed.  
4. Because the supply and exhaust air streams are  
completely separate, there is very little cross  
leakage of any dust or germs.  
Is an ERV better than an HRV?  
NOT NECESSARILY!! In cold climates such as most  
of North America, an HRV works better than an ERV.  
This is because the air inside the home during the  
winter months will be more humid than the outside air.  
An ERV would transfer the latent heat (humidity) from  
the exhaust air back into the incoming airstream. This  
will aggravate moisture problems in the home and  
encourage the growth of mold and mildew. If the air in  
the home is too dry for comfort, an ERV will not help. A  
humidifier should be used to increase the humidity to  
a comfortable level.  
Can the core become clogged with dust?  
Because the surface of the core is a turbulent flow  
area, dust sticks to it easily; however, because the  
inside of the element is a laminar flow area, virtually no  
dust sticks to it.  
Where do you use an ERV instead  
of an HRV?  
An ERV is recommended for warm, humid areas with  
heavy air conditioning use. As there is no defrost in an  
ERV it is not recommended for areas where the  
temperature drops below -4˚C (25˚F)  
What is the maintenance?  
About once a year you should use a vacuum cleaner  
to remove the dust from the core's surface. DO NOT  
WASH WITH WATER!!  
Is an air filter needed?  
To prevent clogging of the core, an air filter should  
always be installed on the supply and exhaust sides of  
the core.  
Why transfer moisture in the summer  
(cooling season)?  
The enthalpic core will allow moisture to be transferred  
from a humid air flow to a dry air flow. This property is  
useful in the cooling season if an air conditioning  
system is used to lower the indoor humidity. You will  
then have dry, cool air in the exhaust of the ERV, and  
warm humid air in the supply stream. With these  
conditions, the ERV will be able to transfer the  
moisture and heat of the supply air to the exhaust air.  
In this way, the ERV will supply to the home air which  
is cooler and drier than outside. Remember that an  
ERV is not a dehumidifier, and on its own will not take  
moisture out of the air.  
How much ventilation do I need?  
During seasons when your windows and doors are  
closed, the ERV should operate continuously when  
the dwelling is occupied, and either continuously or  
intermittently when not occupied.  
For most installations the ERV will normally be set to  
operate continuously on low speed with the option of  
going to high speed as the need arises. For example;  
if you are entertaining and there is a large number of  
people present (some may be smoking), the unit  
should be switched to high speed.  
So why use an ERV?  
A properly operating air conditioner will not only lower  
the temperature in your house, but will also lower the  
humidity level. This prevents an uncomfortable cold  
Your ERV may be equipped with automatic or manual  
switches, but all ERVs will have a manual speed  
control override.

Locat ion for Mount ing  
The Duct work Syst em  
The HRV/ERV must be located in a conditioned  
space where the surrounding air temperature  
does not fall below 60˚F (16˚C). The unit must be  
mounted level (horizontal). The warranty will be  
void if these conditions are not met.  
A properly designed ducting system will allow the  
HRV/ERV to operate at its maximum efficiency.  
(Air flow will be restricted by undersized ducting,  
use of too many elbows, tees, bends, etc.).  
Always try to keep duct runs as short and  
straight as possible.  
Typically the HRV/ERV is positioned close to  
an outside wall or the roof to simplify the  
connections and keep the length of insulated  
ducting required for the fresh air intake to a  
minimum.  
NOTE: Fully insulated ducting with an integral  
vapour barrier must be used on all runs  
passing through unheated areas in order  
to avoid condensation problems and  
energy losses from the air steams.  
A minimum clearance of 36 inches (90 cm) in  
front of the HRV/ERV is recommended to service  
the ventilator. The HRV/ERV may be mounted on  
an equipment platform providing the drain hoses  
are clear and there is sufficient space to open the  
doors for servicing.  
All joints must be airtight, sealed and impervious  
to moisture. See specification sheets for each  
unit for exact duct sizes and location.  
To minimize pressure drop and noise, galvanized  
metal ducts, properly sized, are recommended.  
Keep ducting as short as possible and use a  
minimum of elbows and tees. Connecting sections  
and shorter runs may be flexible ducting one size  
larger than the metal equivalent. Use flexible duct  
connectors at the HRV/ERV to avoid noise  
transmission.  
Install the drain pans in the bottom of the  
HRV/ERV so the drain (not on all models)  
connections protrude through the holes provided.  
Use drain hoses with hose clamps to connect the  
drain pan outlets to a floor drain or standpipe.  
Make sure the drain line slopes down to the  
outlet. If this is not possible a condensate pump  
will be required for positive removal of the water.  
Protect the drain line from freezing.  
All duct joints must be secured with screws,  
rivets or duct sealant and sealed with aluminum  
duct tape to prevent leakage.

Out side Weat herhoods  
The weatherhoods must have built-in “bird” screen with  
1/4 in (63.5 mm) minimum mesh to prevent birds and  
rodents from entering into the ductwork. Do not use  
smaller mesh as it will be very susceptible to plugging  
up. Gravity dampers at the vents must not be used as  
they will restrict air flow and often “seize up”. The  
preferred location of the outside weatherhoods is:  
All duct joints must be fastened with screws, rivets or  
duct sealant and wrapped with a quality duct tape to  
prevent leakage. We recommend aluminum foil tape.  
St ale Air Ret urn Syst em  
The stale air return system is used to draw air from the  
points in the building where the worst air quality  
problems occur. Balancing dampers and/or adjustable  
grilles are recommended on all return air lines which  
are used during installation to help balance the “draw”  
from different areas of the building.  
• no less than 10 ft. (3 m) apart from each other  
• at least 18 in ( 46 cm) above snow line or  
ground level  
• away from sources of contaminants, such as  
automobile exhaust fumes, gas meters,  
garbage cans, containers, etc.  
Alternately, the stale air may be drawn directly from  
the return air duct. When this system is used, the air  
handler’s blower must constantly operate. The exhaust  
takeoff connection must be at least a 3 ft (1 m) from  
a directly connected HRV/ERV supply duct if both are  
connected to the same duct run. Static pressure of the  
air handlers return system should be noted and  
compensated for if, it is apparent that the static  
pressure of the return in the air handler will exceed  
.1 to .15” W.C.  
• not exposed to prevailing winds, whenever  
reasonable possible  
The outside perimeter of the weatherhood must be  
caulked to prevent leakage into the building.  
The design and size of the weatherhoods or louvres  
chosen by the installer must allow for adequate free  
area. Water and debris penetration of the system is  
minimized when the airflow does not exceed 1000 FPM  
(5.08 m/s) free area velocity.  
A damper located just prior to the HRV/ERV is  
required to balance the stale air exhausted with the  
fresh air supply entering the building.  
Ducting from the Weatherhoods  
Return air suction points should be located on the  
opposite side of the room from the fresh air inlet. The  
inlets may be located in the ceiling or high on the walls  
and fitted with inlet grilles.  
Galvanized sheet metal ducting with sufficient cross  
section with an integral single piece vapour barrier should  
be used to connect the HRV/ERV to the weatherhoods.  
All ducting must meet UL Class 1 requirements.  
Many commercial activities produce air contaminants in  
the form of dusts, fumes, mists, vapours and gases.  
Contaminants should be controlled at the source so that  
they are not dispersed through the building nor allowed  
to increase to toxic concentration levels. The ventilator  
allows for economical operation of the HVAC system  
while effectively removing contaminants from the space.  
In designing the exhaust portion of the system  
the exhaust grilles are placed so as to remove the  
contaminants while not allowing them to enter the  
breathing zone of the occupants.  
A minimum R value of insulation should be equal to  
4 (RSI 0.75)  
A good bead of high quality caulking (preferably acousti-  
cal sealant) and taping with a high quality aluminum foil  
tape is recommended to seal the duct to both the  
HRV/ERV and the weatherhood.  
Warmside Duct ing - General  
Ducting from the HRV/ERV to the different areas in the  
building should be galvanized metal whenever possible.  
For contaminants that are lighter than air, grilles should  
be located high on the wall. If contaminants are heavier  
than air, a lower placement of the grilles will be  
required. Information on a contaminants specific gravity  
and toxicity should be available from chemical data  
sheets.  
To minimize airflow losses in the ductwork system, all  
ducts should be as short as possible and with as few  
bends or elbows as possible. 45° elbows are preferred  
to 90° elbows. Use “Wye” (Y) fittings instead of “Tees”  
(T) whenever possible.

Fresh Air Supply Syst em  
The Int egrat ed HVAC Syst em  
Figure A and B  
The fresh air supply ductwork from the HRV/ERV may  
be directly connected to the return air duct of the  
forced air system. Check the air flow balance of the  
HRV/ERV with the air handler blower both “ON” and  
“OFF” to determine that it does not imbalance the  
HRV/ERV more than 10%. Also, it is advisable to  
include a short length of flex duct or other non-metallic  
connector in this hard ducted line in order to keep  
the HRV/ERV acoustically isolated and separately  
grounded (electrically) from the air handler. This will  
avoid a possible shock hazard to service people if a  
short to ground develops in one of the devices.  
The HRV/ERV has become an integral component of  
the HVAC system. Figure A shows an HRV/ERV unit  
providing fresh air directly to the return air plenum of a  
rooftop heat/cool unit.  
In the balanced airflow system, the HRV/ERV exhaust  
removes stale room air (eg. from lunch room, storage  
or copy area) and returns to the space an equal  
amount of fresh outdoor air, making the use of an  
economizer obsolete in conjunction with an HRV/ERV.  
It may be necessary to install a separate fresh air supply  
ductwork system if the heating is other than forced air.  
Many buildings have ceiling return air plenum as  
in Figure B. Fresh air from the HRV/ERV can be  
introduced directly into the ceiling space but this  
should occur near the air handler’s intake.  
When installing an HRV/ERV, the designer and  
installer should be aware of local codes that may  
require smoke detectors and/or firestats in the HVAC  
or HRV/ERV ductwork.  
By operating the HRV/ERV on a 24 hour/7 day battery  
backed timer, the unit can be set to operate only when  
occupancy or indoor conditions require the air  
exchange.  
Because an HRV/ERV is designed to bring fresh air  
into the building, structures may require supply voltage  
interrupt when smoke or flame sensors are triggered,  
or when a central fire alarm system is activated.  
In installations where it is satisfactory to provide  
general exhaust from the space, the air to be  
exhausted may be taken directly from the return air  
plenum to the HRV/ERV as it is drawn back to the air  
handler. Fresh air supplied by the HRV/ERV is then  
introduced directly into the return air plenum but at a  
location closer to the air handler. The air handler  
would have a constant running blower to effectively  
distribute the fresh air and remove the stale air.  
Balancing dampers would be located in both the  
HRV/ERV supply and exhaust ducts between the  
return air plenum and the HRV/ERV.  
Supply air grilles may be ceiling or high wall mounted.  
Avoid locating incoming fresh air grilles that could  
cause a direct draft on the occupants as the incoming  
air may be below room temperature. A reheat duct  
heater can be installed to improve occupant comfort.  
The use of balancing dampers or adjustable grilles to  
balance the flow rates into various rooms is  
recommended.  
The use of balancing dampers or adjustable grilles  
as supply air diffusers and air exhaust covers are  
recommended. TECHGRILLES™ are round, efficient,  
sound absorbing devices available in 4”, 5”, 6” and 8”  
(100, 125, 150, and 200 mm) models.  
NOTE: At no time should the air handler T.E.S.P. on  
the return duct exceed that of the HRV/ERV .

accumulation. After the defrost period, the fresh air  
supply fan automatically returns to the normal speed  
and fresh outside air continues to be drawn into the  
building. Water from the melted frost collects in the  
bottom drip pans and drains out through the bottom  
drain connections. The defrost cycle repeats  
automatically until the air temperature rises  
above 27˚F(-3˚C).  
WARNING: In order to prevent electric shock when  
cleaning or servicing the HRV/ERV, it is extremely  
important to confirm the polarity of the power line that is  
switched by the safety (disconnect) switch whose control  
arm is located on the outside of the electrical control box  
area. The hot line (black) is the proper line to be switched.  
To confirm the proper polarity, use a voltmeter or test lamp  
to make sure there is no power after the switch when the  
door is open. Check between that point and ground (on the  
cabinet). This must be done as occasionally some  
buildings are improperly wired. Always make sure the  
HRV/ERV is properly grounded.  
DAMPER DEFROST  
Models 700DD, 850DD, 1200DD  
These damper defrost HRV’s have an electronically  
controlled damper defrost mechanism. If the outside  
temperature drops below 27˚F(-3˚C ), the defrost timer  
is activated. A motor driven damper door mechanism  
opens the defrost port and at the same time closes off  
the supply air from outside. After approximately 3  
minutes, the damper operates in the opposite direction  
to close off the defrost port and reopen the fresh air at  
the supply port. The 27.5 minute wait time and 3  
minute defrost cycle repeat until the temperature again  
rises above 27˚F (-3˚C).

FAN DEFROST  
Models 700FD, 850FD, 1200FD  
Fan defrost HRV’s are equipped with an electronically  
controlled fan defrost system to remove frost that  
collects on the warm air side of the aluminum heat  
transfer surfaces of the heat exchanger core. When  
the outside air temperature drops below 27˚F(-3˚C),  
defrost is activated which provides for an automatic  
defrost cycle. During the automatic defrost cycle the  
fresh air supply is shut off while the exhaust fan contin  
ues to operate. This allows warm inside air to  
flow through the heat exchanger core melting frost  
This procedure will simulate a defrost that would occur  
automatically in the field when the outside temperature  
drops below -3˚C (27˚F).

to high speed from whatever setting the speed  
control was on. The terminal strip can also be  
wired to allow the unit to be turned off from a  
remote location as well as from high to low from  
a remote location. To wire the unit in this  
configuration you would need two electrical on/off  
switches to be installed at the remote location  
into a double gang electrical enclosure or side by

Self Test  
Each time the HRV/ERV is powered/energized the self  
test function will automatically initiate. During the self  
test the HRV/ERV will cycle through all the speeds  
available (1-5), test the damper motor operation and will  
default back to the previous mode/speed selection,  
(factory default is Speed 1). Total self test duration is  
approximately 1 min. 30 sec.  
Plugging in the HRV/ERV energizes the unit. A self test  
function will be performed every time the HRV/ERV is  
energized (refer to “Self Test” for more details). After  
the self test has completed successfully the HRV/ERV  
will default to Speed 1. This is the factory default  
setting. Follow the instructions found on the HRV/ERV  
door to select desired mode and speed, or refer to the  
instructions found on the following page.  
Aut omat ic Defrost Operat ion  
(Not on all models)  
Control Module  
The advanced technology of the digital microprocessor  
automatically activates the defrost system only as it is  
needed. To be an efficient heat recovery device, the  
HRV/ERV must effectively provide for core defrost as well  
as providing efficient heat exchange. As outdoor  
conditions cool, the temperature sensor (thermistor) tracks  
the supply air temperature. The thermistor then sends its  
signal to the microprocessor (circuit board) which initiates  
only the defrost cycle time required to clear the core. On  
recirculating defrost models, the core is defrosted when  
the supply air port is automatically blocked off and exhaust  
air is redirected back through the HRV/ERV. On damper  
defrost models, the core is defrosted when the supply air  
port is automatically blocked off and the warm air  
surrounding the HRV/ERV is drawn in through the defrost  
port. The mode indicator will flash RED during the defrost  
cycle. This dramatic advance makes more energy  
available for recovery as the unit spends less time in  
defrost mode. By optimizing the defrost cycle, the  
HRV/ERV combines money saving performance with a  
well designed and reliable control system.

installed in a remote location, all optional controls will still  
be wired to the Control Module on the HRV/ERV. When  
remotely mounted on its own, the Control Pad is wired to  
the Control Module by 3 wire (min. 20 gauge). Connect  
the colour coded terminals to the corresponding terminals  
on the Control Module. When the Control Pad is remotely  
mounted in the Ventilation Dehumidistat or Air Sentry,  
refer to optional controls page for wiring requirements.  
DEHUMIDISTAT - a control device that senses the amount of  
moisture in the air and will activate high speed fan operation  
when the air moisture level exceeds the control setting. The  
optimum air moisture level (or relative humidity [Rh]) in the  
typical home is in the range of 30 to 40% Rh.  
RESET - whenever resetting of the HRV/ERV is required,  
simply disconnect power for 30 seconds.  
STANDBY MODE - the HRV/ERV is energized and waiting for fan  
operation to be initiated by a remote device or manual override.

PITOT TUBE AIR FLOW BALANCING  
It is necessary to have balanced air flows in an HRV/ERV. The volume  
of air brought in from the outside must equal the volume of air exhausted  
by the unit. If the air flows are not properly balanced, then;  
• The HRV/ERV may not operate at its maximum efficiency  
• A negative or positive air pressure may occur in the house  
• The unit may not defrost properly  
For general balancing it is sufficient to move the pitot tube around in  
the duct and take an average or typical reading. Repeat this procedure  
in the other (supply or return) duct. Determine which duct has the high-  
est airflow (highest reading on the gauge). Then damper that airflow  
back to match the lower reading from the other duct. The flows should  
now be balanced. Actual airflow can be determined from the gauge  
reading. The value read on the gauge is called the velocity pressure.  
The Pitot tube comes with a chart that will give the air flow velocity  
based on the velocity pressure indicated by the gauge. This velocity  
will be in either feet per minute or metres per second. To determine the  
actual airflow, the velocity is multiplied by the cross sectional area of the  
duct being measured.  
• Failure to balance HRV/ERV properly may void warranty  
Excessive positive pressure may drive moist indoor air into the external  
walls of the building where it may condense (in cold weather) and  
degrade structural components. May also cause key holes to freeze up.  
Excessive negative pressure may have several undesirable effects.  
In some geographic locations, soil gases such as methane and radon  
gas may be drawn into the home through basement/ground contact  
areas. Excessive negative pressure may also cause the backdrafting of  
vented combustion equipment.  
This is an example for determining the airflow in a 6" duct.  
The Pitot tube reading was 0.025 inches of water.  
From the chart, this is 640 feet per minute.  
The 6" duct has a cross sectional area of  
The airflow is then:

5. Air flows in branch lines to specific areas of the house should be  
adjusted first prior to balancing the unit. A smoke pencil used at the  
grilles is a good indicator of each branch line's relative air flow.  
6. After taking readings of both the stale air to the HRV/ERV duct and  
fresh air to the house duct, the duct with the lower CFM ([L/s]  
velocity) reading should be left alone, while the duct with the higher  
reading should be dampered back to match the lower reading.

The accuracy of the air flow reading will be affected by how close to  
any elbows or bends the readings are taken. Accuracy can be  
increased by taking an average of multiple readings as outlined in the  
literature supplied with the Pitot tube.  
BALANCING PROCEDURE  
Pitot tube and gauge  
The following is a method of field balancing an HRV/ERV using a Pitot tube,  
advantageous in situations when flow stations are not installed in the duct-  
work. Procedure should be performed with the HRV/ERV on high speed.  
DUCT  
AIR FLOW  
The first step is to operate all mechanical systems on high speed, which  
have an influence on the ventilation system, i.e. the HRV/ERV itself and  
the forced air furnace or air handler if applicable. This will provide the  
maximum pressure that the HRV/ERV will need to overcome, and allow  
for a more accurate balance of the unit.

PART NO. 99-167  
Drill a small hole in the duct (about 3/16"), three feet downstream of  
any elbows or bends, and one foot upstream of any elbows or bends.  
These are recommended distances but  
Place pitot tube a minimum of 18" from blower or elbows  
the actual installation may limit the  
amount of straight duct.  
Outdoors  
The Pitot tube should be connected to a  
magnehelic gauge or other manometer  
capable of reading from 0 to 0.25 in. (0-  
62 Pa) of water, preferably to 3 digits of  
resolution. The tube coming out of the  
top of the pitot is connected to the high  
pressure side of the gauge. The tube  
coming out of the side of the pitot is con-  
nected to the low pressure or reference  
side of the gauge.

SERVICE/ MAINTENANCE  
Servicing your HRV/ERV on a regular schedule will  
result in optimum operating efficiencies and  
prolonged life of the equipment.  
sharp, and the core itself susceptible to damage  
if dropped.  
When removing the core, the location it is removed  
from should be noted.  
Due to numerous applications in which this  
equipment can be installed, it is difficult to predict  
servicing intervals. In certain situations where there  
is heavy smoke, servicing the equipment every one -  
two months may be needed; whereas ventilating a  
meeting room for example for carbon dioxide may  
only need service every six months to a year.  
The core is removed by carefully pulling the core  
outward from the unit, sliding it evenly along its “H  
channel” supports found in each corner of the core.  
Note the core may have some resistance when  
sliding out. Avoid tilting the core as this will result in  
its edges catching the H channel and temporarily  
preventing its removal.  
MOTOR  
Access to the motor is through the front service  
doors. Note heat exchanger core can be removed to  
provide more room. See CORE in this section.  
In most cases, washing the core in a mild  
detergent and warm water will be all that  
is needed to completely clean them. Do not use  
harsh chemicals as this may cause corrosion in the  
HRV. The time between core service will depend  
on the application the HRV has been installed in.  
It can be as often as one - two months or at the very  
least, cleaned every six months. When reinstalling  
the core you must note foam location and drip  
edge location for proper core placement.  
The motor is a permanent split capacitor type (PSC)  
which uses a sleeve mechanism to steady the shaft.  
There is an oil wick beside the sleeve which supplies  
oil to it on a continuous basis.  
If the motor does not have oil tubes, no maintenance  
is required.  
See diagram below.  
Access to the wick is through oil tubes, (two per  
motor) located in the motor case itself. These oil  
tubes are either capped with yellow plugs, (which  
need to be removed for oiling) or have clear tubes  
protruding from them.  
ERV CORE (ERV only)  
Remove core and vacuum or use low pressurized air to  
clean core. Do not wash or submerse in water.  
With the core in its proper position, place the  
bottom flange, (approximately 1/4”) into its H channel  
support, then place the left side, the right side and  
finally the top flange into place in the same fashion.  
Once all four corners are in place, push the core  
evenly into the cabinet until it reaches the back. Be  
sure the drip edges are overlapping the drip trays.  
In either case an oiling device such as an “Oil  
Telespout” filled with 20 S.A.E. non-detergent electric  
motor oil should be used to put oil inside the tubes. A  
couple of drops of oil once a year will do.  
DO NOT OVER OIL!  
HRV CORE (HRV only)  
The heat exchange core is accessible through the  
front service door. Special care and attention should  
be given to this component as the edges may be  
Note the core will protrude slightly out from the front  
of the cabinet, this is so the access door, when  
closed, ensures a tight fit.

FILTERS  
DUCT WORK  
It is a good idea to inspect ducting, outside  
weather hoods (wall caps), and grilles for blockage  
and dirt buildup, at least every six months.  
Open front service door to access the filters  
located in both supply and exhaust air streams.  
Note to remove and install filters, it may be easier  
to first remove the core(s). See CORE.  
Outside weather hoods should be protected by a  
rodent screen which can plug up with debris.  
Also, it is a good idea to visually confirm that  
the fresh air supply is free from any sources of  
contamination, such as other vented combustion  
equipment added after the fact.  
The filters are designed to stop large particles  
from entering in the core. The filters are fastened  
in place by a metal spring rod. To remove filters  
from core(s) simply pull the rod from one end,  
outward until free from core lip, and remove.  
Only use warm water with a mild detergent to  
wash the filters. Do not use harsh chemicals.  
DAMPER MOTOR  
The damper motor, (if applicable) is a self  
contained motor and does not require service.  
The damper door attached to the motor could use  
a little lithium grease on the shaft opposite the  
motor, where it enters its holder, once every  
two - three years.  
The time between filter service will depend on the  
application the HRV/ERV has been installed in. It  
can be as often as one - two months or at the  
very least, cleaned every six months.  
CONDENSATE DRAINS  
The condensate drains consist of two drain pans  
which may collect water after the HRV/ERV  
initiates a defrost cycle, and a drain line to  
remove the condensate.  
General Maint enance  
As a final step in a routine maintenance  
schedule, it is a good idea to confirm operation of  
the system, checking speed control functions and  
remote control operation, if applicable.  
Maintenance on this portion of the system should  
be done as often as possible and should not  
exceed six months. Note bacterial growth in  
standing water is a major concern to healthy  
indoor air quality, and should be avoided whenever  
possible.  
Wipe the inside of the cabinet to remove dust and  
cob webs as needed.  
It is a good idea to keep a service/maintenance  
log of the unit.  
To clean these components, open the front  
service door and flush the pans with water.  
Ensure that the pans drain completely and in a  
reasonable amount of time. Note if the water  
does not drain right away, check for blockage in  
the drain line, also check that the drain line has a  
good slope to it. (1/8 - 1/4” per foot)  
The drain line itself should have a “P” trap in it  
below the HRV/ERV which is to be filled with  
water to prevent odours or gases from entering  
back into the unit. When flushing out the drain  
pans, this too will be flushed out, and the water  
that was there will be replaced with clean water.
