Getting to Know your Heat and Energy Recovery Ventilator (FC Series)  
Thank you for purchasing a Field Control Heat/Energy Recovery  
Ventilator (HRV/ERV). The HRV/ERV provides fresh air to your  
home while recovering energy from the air it exhausts.  
There are numerous benefits to a properly installed, operated, and  
maintained HRV/ERV:  
• Recovers the majority of the energy contained in the exhausted  
stale air.  
• Uses the recovered energy to preheat or precool the fresh outdoor  
air introduced into the house  
• Distributes the fresh air throughout your home.  
• Exhausts the stale, contaminated air, found in today’s tight  
buildings.  
Ventilation and Control Options*  
Optional Controls are available to adjust the amount of ventilation  
in your home:  
• The Healthy Home System™ Control (HHSC) will automatically  
deliver fresh air to your home.  
• The Dehumidistat Ventilation Control (DHVC) is a manual  
control which features ON/OFF, High speed, Low Speed, and an  
electronic dehumdistat.  
• The Dehumidistat Control (DHI) can be used in conjunction with  
the HHSC to provide additional ventilation for high indoor  
humidity levels.  
*Refer to the individual control pages of this manual for more  
information about these controls.  
How the Dehumidistat Works (Colder Climates)  
High indoor humidity levels, during the heating season, have  
become a problem in many well insulated, tight homes. Excessive  
condensation on the windows is a visual sign of high indoor  
humidity levels. High indoor humidity levels can result in mold and  
mildew and the eventual degradation of the building structure itself.  
Your HRV/ERV reduces indoor humidity levels when the  
outdoor air is drier than the indoor air. These conditions usually  
occur during the heating season when outdoor temperatures are less  
than 15°C (59°F). During the heating season, the operation of the  
HRV/ERV may reduce indoor humidity levels sufficiently to  
eliminate the need for further dehumidification.  
Refer to the main control instructions located in the Operation and  
Installation Manual for instructions on how to set the dehumidistat.  
The dehumidistat function on the main control should be set to OFF  
for all seasons except the heating season, because a dehumidifying  
effect occurs only when the outdoor air is dryer than the indoor air.  
Set the RH level to 80 to turn the dehumidistat OFF. (Refer to the  
control instructions for information on how to set the  
Dehumidistat).  
DEHUMIDISTAT DISABLE - automatically disables the  
dehumidistat function on the main control when outdoor  
temperatures exceed 15°C (59°F) for a full 24 hour period. All other  
HRV features and functions operate normally while the  
dehumidistat function is disabled.  
If your home requires further dehumidification, use the  
dehumidistat feature located on any optional main control (refer to  
the Operation and Installation Manual for Optional Control  
information). This feature aggressively addresses high indoor  
humidity levels by initiating high speed ventilation when the indoor  
humidity levels rise above the adjustable set point on the control.  
DEHUMIDISTAT RE-ENABLE - automatically re-enables the  
dehumidistat function if either the outdoor temperature drops below  
15°C (59°F) for a full 24 hour period or if the HRV is reset  
(unplugged for 30 seconds).  
Glossary and Additional Information  
DEFROST MODE - To ensure reliable operation during cold  
weather, the HRV automatically cycles through its defrost mode  
when the outdoor temperatures drop below freezing.  
SELF-TEST - Each time the HRV/ERV is powered/energized, the  
self-test function automatically initiates. The HRV/ERV cycles  
through the available speeds and tests the damper motor operation.  
The HRV/ERV defaults back to the previous operational mode and  
speed selection after the self-test (approximately 60 seconds in  
duration).  
HRV/ERV - a Heat Recovery Ventilator (HRV/ERV) is designed  
to provide fresh air into a building while exhausting an equal  
amount of stale air. During the winter months, heat recovered from  
the stale air, before it is exhausted to the outdoors, warms the  
incoming cold fresh air. During the summer months, when the  
indoor space is air conditioned, the HRV/ERV helps to cool the  
incoming fresh air with the cool exhausted stale air.  
STANDBY - The HRV/ERV is powered/energized and waiting for  
ventilation to be initiated by an external control.  
TIMERS - These optional controls may be installed at specific  
exhaust locations (bathrooms etc.) to initiate high speed ventilation.  
Warranty  
Heat Recovery Ventilators (HRV) carry a Lifetime Warranty on the  
heat recovery core and a 5 (five) year replacement parts warranty.  
Energy Recovery Ventilators (ERV) carry a 5 (five) year warranty  
on the energy recovery core and a 5 (five) year replacement parts

Healthy Home System Control (HHSC)  
The Healthy Home System Control (HHSC) activates the  
HRV/ERV automatically to deliver fresh air into your home.  
Setting the Control  
The duration of the ventilation rate is adjustable on the HHSC.  
Your installer sets up this control during the installation of your  
system . Refer to the instructions that came with the HHSC for the  
setup information.  
The Healthy Home System™ Control (HHSC)  
Dehumidistat (Part DH1)  
Your HRV/ERV system produces a dehumidifying effect when  
outdoor humidity levels are lower than indoor humidity levels.  
These conditions occur normally when outdoor termperatures are  
below 60°F. An additional dehumidification effect is achievable  
with the Optional Dehumidistat (Part DH1).  
Dehumidistat Indicator  
LEDs  
Set to the desired humidity  
level. High speed ventilation  
will initiate when the indoor  
moisture level exceeds the set  
point on the control.  
The Optional DH1 Control may be combined with the Healthy  
Home System Control (HHSC). The DH1 will initiate high speed  
ventilation when the moisture level in the home exceeds the set  
point on the control. Once the humidity in the house is reduced,  
the HRV will revert back to the HHSC automatic setting. The  
Dehumidistat should be set to OFF for all seasons except the  
heating season.

Maintenance Routine for HRV  
1. Inspect Exterior Hoods at least once a month.  
Make sure exhaust and fresh air supply hoods are not blocked or  
restricted by leaves, grass, or snow. In winter, it is especially  
important to make sure snow is not blocking the hoods or that frost  
has not built up on the wire mesh (bird screen).  
6. Clean Duct Work if Required  
The duct work running to and from the HRV may accumulate dirt.  
Wipe and vacuum the duct once every year. You may wish to  
contact a Heating/Ventilation company to do this.  
7. General Maintenance - Twice a Year  
Wipe down the inside of the cabinet with a damp cloth to remove  
dirt, bugs, and debris that may be present.  
WARNING: Blockage of hoods may cause an imbalance.  
2. Clean Air Filters (clean twice a year)  
The standard filters equipped with your HRV are removable and  
washable.  
a) simply open access door and slide core out  
b) remove filter clips  
c) once clips are removed filters can be taken off the core to be  
rinsed with water or a combination of mild soap and water. Do  
not clean in the dishwasher  
d) to re-assemble, place clean filter(s) (wet or dry) back into their  
positions against the core and return clips to their original  
position  
8. Cleaning the Fans  
Fans may accumulate dirt causing an imbalance and/or excessive  
vibration of the HRV. A reduction in the air flow may also occur.  
In new construction this may result within the first year due to  
heavy dust and may occur periodically after that over time  
depending on the outdoor conditions.  
unplug the HRV and open the service door  
remove the core  
remove ducting (metal and/or flexible insulated type) from  
the red and/or blue ports which are connected immediately  
in-line with the fan assembly  
e) slide core back into its’ original position  
3. Clean Core Twice a Year  
use a small brush, such as an old toothbrush or pipe cleaner,  
and insert first  
a) open access door.  
b) carefully grip ends of core and pull evenly outward. Core may  
be snug, but will slide out of the channel  
c) once removed from the cabinet remove filters  
d) wash core in warm soapy water (do not use dishwasher)  
e) install the clean filters  
f) install clean core  
Note: Core installation label on the outer end of the core.  
(a) through the large opening of the fan  
assembly and then  
(b) through the smaller opening in the end  
of the fan assembly.  
scrub individual fan blades until clean. Avoid moving or  
damaging balancing flat weight, clip is usually found on one  
or more of the fan blades  
To install the clean core:  
a) first mount the bottom flange of the core guide into the bottom  
H channel approximately 1/4” (6mm)  
b) mount the left or right side flange of the core guide  
approximately 1/4” (6mm) followed by the other side  
vacuum and wipe  
reassemble making sure ducting is reattached firmly and  
insulation and moisture barrier are sealed and taped  
c) mount the top flange of the core guide into the top H channel  
approximately 1/4” (6mm).  
Before attempting this task, thought should be given to having a  
qualified service technician complete the service work.  
d) with all four corners in place and the core straight and even,  
push hard in the centre of the core until the core stops on the  
back of the cabinet.  
NOTE: Core will appear to stick out from cabinet approximately 1/8”  
(3mm). This is designed this way so that the access door will fit tight  
against the core.  
WARNING  
Electric shock hazard. Can cause  
injury or death. Before attempting to  
perform any service or maintenance,  
turn the electrical power unit OFF at  
disconnect switch(es). Unit may have  
multiple power supplies.  
4. Motors - Maintenance Free  
5. Drain (condensate) Line - Clean once a year  
Inspect drain line, drain spout, and “P” trap for blockage, mould or  
kinks. Flush with warm soapy water and replace if worn, bent or  
unable to clean.

Port Configuration and Airflow  
Model FC95HRV  
In order to make the HRV as space efficient as possible, the  
INDOOR supply and return ports are converted from round to oval  
shape. Overall size of the port remains the same. Simply bend a  
standard duct fitting to the correct shape, and attach to the oval  
port using the same method as for a round port.  
Round port bent to oval  
FC95HRV Air Flow  
Stale air enters the FRONT-RIGHT side port. The air passes down  
the front half of the core, then up the back half of the core and out  
the RIGHT-REAR port.  
Fresh outdoor air enters the LEFT-REAR port and passes down  
the back half of the core. Then the fresh outdoor air passes up the  
front half of the core and out the LEFT-FRONT port. This  
configuration allows the air to actually travel through the core  
twice, which makes the FC95HRV nearly as efficient as a double  
core unit.

Installation Methods  
The Three Methods of Installation  
The following three installation methods are for the  
HRV/ERV system:  
Installing the Ducting Between the HRV/ERV &  
Living Areas in the House  
A well designed and installed ducting system will allow the  
• The Simplified installation.  
HRV/ERV to operate at its maximum efficiency.  
• The Partially Dedicated Installation  
• The Fully Dedicated Installation  
All ducts should be kept short and have as few bends or  
elbows as possible to maximize airflow. Forty-five degree  
elbows are preferred to 90° elbows. Use "Y" tees instead of  
straight tees whenever possible.  
All duct joints must be fastened with screws, rivets or duct  
sealant and wrapped with mastic or quality duct tape to  
prevent leakage. Mastic is preferred but if duct tape is used,  
we recommend aluminum foil duct tape.  
Simplified Installations  
The Simplified Installation draws stale air from the cold air  
return duct of the air handler/furnace and introduces an  
equal amount of fresh air farther downstream into the cold  
air return. Refer to "Simplified Installation Diagrams".  
Galvanized (rigid) ducting from the HRV/ERV to the living  
areas in the house is recommended whenever possible  
although flexible duct can be used in moderation if  
necessary.  
A short length (approximately 12 inches or 300mm) of non-  
metallic flexible insulated duct should be connected  
between the HRV/ERV and the supply/exhaust duct system  
to avoid possible noise transfer through the duct system.  
The air handler/furnace blower must be running when the  
unit is operating for this system to be effective. Refer to  
"Interlocking the HRV/ERV to an Air Handler/Furnace  
Blower".  
Partially Dedicated Installations  
The Partially Dedicated Installation draws stale air from  
specific points in the house and introduces an equal amount  
of fresh air into the cold air return. Refer to "Partially  
Dedicated Installation Diagrams".  
All ducts running through attics and unheated spaces must  
be sealed and insulated to code.  
Stale air ducts should be installed in areas of the home  
where the poorest indoor air quality exists (bathrooms and  
kitchen). Each location with a stale air duct should have a  
timer to initiate high speed ventilation. Refer to "Optional  
Timers" in this manual.  
ATTENTION  
Applications such as greenhouses, atriums,  
swimming pools, saunas, etc. have unique  
ventilation requirements which should be  
addressed with an isolated ventilation system.  
The air handler/furnace blower should be running when the  
HRV is operating to evenly distribute the fresh air  
throughout the house. Refer to "Interlocking the HRV/ERV  
to an Air Handler/Furnace Blower".  
Fully Dedicated Installations  
The Fully Dedicated Installation draws stale air from  
specific points in the house and delivers fresh air to specific  
locations of the house. This system is not connected to an  
air handler/furnace. Refer to "The Fully Dedicated  
Installation Diagrams" in this manual.  
Stale air ducts should be installed in areas of the home  
where the poorest indoor air quality exists (bathrooms and  
kitchen). Each location with a stale air duct should have a  
timer which will initiate high speed ventilation. Refer to  
"Optional Timers" in this manual.  
Fresh air ducts should be installed to all bedrooms and  
living areas, excluding bathrooms, kitchen and utility areas.  
Grilles should be located high on a wall or in ceiling  
locations. Grilles that diffuse the air comfortably are  
recommended. Refer to "Grilles" in this manual. Special  
care should be taken in locating grilles if the floor is the  
only option available. Areas such as under baseboard  
heaters will help to temper the air.  
Optional in-line duct heaters are available for mounting in  
the supply duct work to add heat if required.

Simplified Installation Diagrams  
Simplified Installation (Return/Return Method)  
Key Points  
The HRV/ERV must be balanced.  
It is mandatory that the furnace blower run continuously or  
HRV/ERV operation be interlocked with the furnace  
blower. (Refer to “Interlocking the HRV/ERV to an Air  
Handler/Furnace Blower.”)  
The duct configuration may change depending on the  
HRV/ERV model. See specifications for your unit.  
Check local codes / authority having jurisdiction for  
acceptance.  
A backdraft damper is required in the exhaust air duct to  
prevent outdoor air from entering the unit when the  
Furnace/Air Handler is running and the unit is in Standby,  
OFF or Recirculate.  
Sizing the Ductwork  
It is the responsibility of the installer to ensure all ductwork is  
sized and installed as designed to ensure the system will  
perform as intended.  
The amount of air (cfm) that an HRV/ERV will deliver is  
directly related to the total external static pressure (E.S.P.) of  
the system. Static pressure is a measure of resistance imposed  
on the blower by length of duct work plus the number of  
fittings used in the duct work.

WARNING  
The Stale Air to Outside air duct requires  
a Backdraft Damper. This damper prevents  
outdoor air from entering the HRV  
during the operation of the Furnace/  
Air Handler while the HRV is in standby,  
OFF or Recirculate.  
Installation Notes  
Unit is normally balanced on HIGH speed with the furnace blower ON.  
A minimum separation of 40 inches (1m) is recommended between the  
two direct connections.  
The exhaust air connection should be upstream of the supply air  
connection to prevent exhausting any fresh air.  
Weatherhood arrangement is for drawing purposes only. Six feet (2m)  
minimum separation is recommended. The Weatherhood must also be 18"  
(460mm) above grade minimum.  
The airflow must be confirmed on site using the balancing procedures found in this manual

Installation  
Location  
Install the unit in a heated space that provides convenient space for  
service access. A typical location is in either a mechanical room or  
an area close to the outside wall within close proximity to where  
the weatherhoods are mounted. If a basement area is inconvenient  
or non- existent, install the unit in a utility or laundry room.  
WARNING  
Improper installation, adjustment, alteration,  
service or maintenance can cause property  
damage, personal injury or loss of life.  
Installation and service must be performed by  
a qualified installer or service agency.  
Attic installations are not recommended due to:  
A) the complexity of work to install  
B) freezing conditions in the attic  
C) difficulty of access for servicing and cleaning  
CAUTION  
Leave sufficient clearance at the front of the access door for  
servicing the air filters and core. The recommended clearance is a  
minimum of 25" (635 mm) for opening and closing the door. Field  
Controls provides four straps for hanging the unit from the  
basement floor joists.  
Unit must be installed level to ensure proper  
condensate drainage. Due to the broad range of  
installation and operational conditions, consider  
the possibility of condensation forming on either

Weatherhood Installation  
Installing the Ducting from the  
Weatherhoods to the HRV/ERV  
Weatherhoods  
Fixed covered weatherhoods have a built-in bird screen with a 1/4"  
(6mm) mesh to prevent foreign objects from entering the  
ductwork.  
The inner and outer liners of the flexible insulated duct must be  
clamped to the sleeve of the weatherhoods (as close to the outside  
as possible) and the appropriate port on the HRV/ERV. It is very  
important that the fresh air intake line be given special attention to  
make sure it is well sealed. A good bead of high quality caulking  
(preferably acoustical sealant) will seal the inner flexible duct to  
both the HRV/ERV port and the weatherhood prior to clamping.

Installation of the Healthy Home System™ Control (HHSC)  
HRV/ERV control. The HHSC is also typically used to  
control an FAD fresh air damper.  
2. Complete all wiring connections before restoring power  
to the HVAC system and HRV/ERV.  
Choose a Location  
The HHSC controller can be installed anywhere in your  
home. To simplify the installation, locate the HHSC control  
near the HVAC system and/or the HRV/ERV, since the  
HHSC does not require routine adjustment or occupant  
interaction.  
Programming the HHSC Control  
1. Balance the fresh and stale airflows as instructed in this  
manual.  
To provide the occupants with direct access to the functions  
of the controls, install optional accessory controls  
throughout the house.  
2. Determine the cfm flow rate as instructed in this manual.  
3. To obtain the desired rate of fresh air exchange, refer to  
the HHSC Control Installation Instructions to determine  
the On/Off timer settings for the HHSC Control. Use the  
cfm flow rate determined in step 2 as the computed or  
measured fresh air flow rate (as calculated in the HHSC  
instructions). To ensure adequate ventilation, ensure that  
the “Fan On” time is equal to or greater than the “Vent  
On” time, as programmed in the HHSC Control.  
4. For continuous operation of the HRV/ERV, set  
“Fan On” and “Vent On” to “Un” (unlimited), and “Fan  
Off” and “Vent Off” to any setting except “Un”. This  
setting also causes the HVAC fan to run continuously.  
NOTE: The HHSC Control is factory programmed with the  
default settings of the two On/Off timer values. No  
configuration is required to use these factory default  
settings.  
How To Install the Controller  
1. Separate the HHSC controller cover from the wall plate  
(mounting base) to expose mounting holes  
(see illustration).  
2. Route wires through large hole in the mounting base.  
Mount base against wall and mark wall through  
3 mounting holes.  
3. If mounting on a metal or wood surface, drill three 1/8-in.  
pilot holes in wall where marked for the supplied  
mounting screws. If mounting on drywall or other  
surface, drill appropriate holes for wall anchors or other  
means of attachment.  
4. Secure mounting base to wall with either the 3 screws  
provided or other fasteners, while ensuring that all wires  
extend through the hole in mounting base.  
5. Adjust length and routing of each wire to reach the  
proper terminal and connector block on mounting base,  
while leaving a 1/4 in. length of extra wire. Strip only  
1/4 in. of insulation from each wire to prevent adjacent  
wires from shorting together when connected.  
6. Connect wires to their respective terminals on the  
connector block. (Figure 1) Both (R) and (C) must be  
connected for proper operation. Improper wiring or  
installation may damage the controller. Ensure wiring is  
correct before proceeding with installation or turning the  
unit on.  
Default settings:  
FAN OFF  
FAN ON  
VENT ON  
VENT OFF  
20 minutes

7. Push any excess wire into wall and against mounting  
base.  
8. Snap cover onto base, while ensuring pins align with  
sockets in connector.  
9. Once powered the HHSC automatically enters into  
operating mode.  
Complete the Wiring Connections  
1. Refer to subsequent wiring diagrams in this manual  
that correspond to the desired control configuration.

Setting “Standby” when using a Main Control  
The HRV/ERV will be “fully-off” when the  
OFF position is selected on the Main Control.  
Timers and /or other controls will not function  
when the HRV/ERV is in the OFF position.  
The “fully-off” feature can be modified to  
“standby-off” by adding a jumper on the  
Terminal Block between 2 (ON) and 3 (RED).  
“Standby” can also be achieved by setting the  
main control to the ON position and selecting  
speed 0*. Timers and /or additional controls  
will initiate high speed ventilation when  
activated.  
CAUTION  
Building codes in some areas require “fully-  
off” functionality. Check with your local  
building authority before modifying the unit  
to “standby -off”.  
Unintentional operation of the HRV by the  
end user may occur if the unit is modified  
from “fully-off” to “standby-off”.

Balancing the Air Flows  
Balancing the air flows is critical to ensuring that the amount of air introduced from the outside of the building equals the  
amount of air exhausted to the outside of the building. If these two air flows are not properly balanced, the following issues  
may occur:  
• A positive or negative pressure may occur in the house  
ATTENTION  
Continuous, excessive, positive pressure may  
• HRV/ERV may not operate at its maximum efficiency  
• The unit may not defrost properly  
drive moist indoor air into the external walls of  
the building. Once inside the external walls, moist  
air may condense (in cold weather) and degrade  
structural components or cause locks to freeze.  
Air Flow Measuring Gauges  
The magnehelic gauge and the digital manometer are suitable  
instruments for the balancing of air flows.  
Continuous, excessive, negative pressure may  
A magnehelic gauge with a scale of 0 to .25" w.c. is suitable  
for accurately measuring air duct velocity. The value on the  
gauge will be velocity pressure. A digital manometer requires  
the ability to display differential pressures at 3 digits of  
resolution.  
have several undesirable effects. In some  
geographic locations, soil gases such as methane  
and radon gas may be drawn into the home  
through basement or ground contact areas, and  
may also cause the backdrafting of vented  
combustion equipment.  
Gauge Attachments  
When sampling an air flow, various attachments are available  
for use on a magnehelic gauge or digital manometer.  
The following illustration shows a magnehelic gauge with  
a scale of 0 to .25" w.c. with a pitot tube attachment. This  
combination will measure the system air velocity pressure  
accurately, regardless of the duct size or shape (either round  
or rectangular).  
Balancing Preparation  
Prior to performing the air balancing procedure, perform the  
following steps:  
• Seal the ductwork system  
• Confirm the installation and proper operation of all the  
components of the HRV/ERV  
• Fully open the balancing dampers

Balancing the Air Flows with a Pitot Tube  
STEP 1. Drill a 3/16” hole in the duct (ideally 3 feet downstream of  
any elbows or bends and 1 foot upstream of any elbows  
or bends) in the Fresh Air and Stale air streams.  
STEP 2. Insert the Pitot tube with the tip facing towards the air  
stream in the Stale Air From Building air stream. Move  
the Pitot tube around in the duct (facing towards the  
airflow) and take an average reading. Record the reading.

A) Review the readings and damper down the duct with the  
highest duct velocity pressure. Repeat Step 2 and Step 3  
until both ducts show indentical readings. For this example,  
the Fresh Air to Building air stream has the highest duct  
velocity pressure.  
Determining the cfm  
After balancing the air flows, calculate the cfm flow rate.  
Example  
This example shows how to determine the air flow for a 6” diameter duct.  
As shown in the illustration, the duct velocity pressure reads 0.025” w.c.  
on the magnehelic gauge. Use the chart that came with the magnehelic  
gauge to determine a duct velocity of 640 feet per minute for a duct  
velocity pressure of 0.025” w.c.  
Cfm Calculation  
cfm = feet per minute x cross section area of duct  
= 640 x 0.196  
= 125  
Cross Section Area of some common round duct sizes:  
0.087 for 4” diameter duct  
0.136 for 5” diameter duct  
0.196 for 6” diameter duct  
0.267 for 7” diameter duct

located on the lower portion of this page).  
Step 8  
Damper down the higher airflow and repeat Steps 5 to 7 as required  
until both airflows are identical (balanced).  
Step 9  
Prepare the air flow measuring device (i.e. Magnehelic Gauge or  
Digital Manometer) by connecting the hoses to the low and high  
pressure side of the gauge.  
Step 2  
Insert the hoses into the rubber fittings from the optional Door Port  
Adapter Kit (part # 99-182). Use light pressure and rotate until  
fitting is snug. Do not extend the hose past the rubber fitting.  
Step 3  
Remove the tape and rubber fittings and reinstall the 4 Door Port  
Covers.  
Open the HRV Door. Remove the 4 Door Port Covers by carefully  
pushing them out from the back side of the door (use the blunt end  
of a large drill bit etc.).

Balancing Dampers  
The FC155HRV and FC200HRV models have factory installed  
Balancing Dampers located in the “Fresh Air to Building” and  
“Stale Air from Building” collars.  
NOTE  
Installations where the HRV is ducted directly to  
the return of the furnace/Air Handler may  
require additional dampening on the fresh air to  
building duct.  
This is due to the high return static pressures  
found in some furnace installations.  
All other units require the installation of balancing dampers (not  
included) in the “Fresh Air to Building” and “Stale Air from  
Building” ductwork. Refer to the installation diagrams in this  
manual for the Simplified, Partially Dedicated, and Fully  
Dedicated systems.  
Observe the location of the screws  
when connecting ductwork to the  
collar. Screws should be located no  
further than 1/2” from the outside  
edge of the collar and they should  
be no longer than 3/4”.  
Push and turn with slotted  
screwdriver. Damper  
automatically locks when  
pressure is released.
