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).

5. Close access doors and power the unit.
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).

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.

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

CROSS SECTION AREA (sq. ft.)
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.
7. Return unit to appropriate fan speed for normal operation

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.

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.
