4. Finding a suitable installation area for HRV.
The HRV unit should be installed in a mechanical room or as close to an outside wall as possible.
This would assure a short run of insulated flexible duct.
The HRV unit must always be installed in an area where the air is tempered to avoid freezing of
the condensate line. The contractor should install the unit in area that is very accessible to allow
the homeowner easy access for maintenance.
You should have access to a condensate drain near the HRV to avoid the use of condensate pump.

Mount the damper motor by aligning the pin on the damper motor to the hole on the unit’s top plate
and the align the damper motor coupling with the damper shaft. (figure 8.2)
Align the damper in the fully closed position. (figure 8.3) Using a 1/8” Allen key tool inserted in the
locking screw, rotate the coupling slightly clockwise just enough to exert a slight torque on the damper
mechanism and tighten the lock screw. (figure 8.4)
Dampers should now be in the fully closed position with no power. Identify desired wiring diagram
shown at page 14 of this guide. Activating the damper motor should open flaps to 90°. If the damper
flap do not open fully, coupling might need to be readjusted to allow for more or less spring tension
when fully closed.

performance
installation
The HRV must be balanced properly in
order to operate at maximum performance
and avoid problems.
Balancing the Unit
installation
Balancing the unit is an important step in
the installation of the HRV. The operation
consists of measuring and regulating the
volume of fresh air from outside passing
through the unit is equal with the exhaust
air from home.
figure 11.1 Balancing Dampers- Model SHMTM and Model SHTM
Step 1:To get proper readings, mount the air flow
A 10% variation is acceptable, in such case,
the volume of exhaust air from home
should be superior than the volume of fresh
air from outside.

from the unit. This will avoid getting unstable airflow
witch could offset the readings. (Figure 11.2)
18”
Step 2:Start with the fresh air from outside duct.
Drill a hole in the conduit and insert the air flow grid.
Make sure to mount the grid following the direction of
the airflow arrow. (Figure 11.3)
Refer to Ventilation Needs, page 3 to
determine what is the volume of air needed
for your specific installation.
Balancing Dampers
figure 11.2 Minimum of 18”
Step 3:The magnehelic gauge needs to be leveled
and should read «0» before taking any readings.
Determine your airflow volume by consulting the grid’s
chart. It can differ from one gauge size to an other.
(Figure 11.4)
Before Starting
the Balancing
Operations
installation
A Magnehelic gauge equiped with an air
flow grid is used to measure the volume of
air passing through the unit and ducting sys-
tem. Make sure that the airflow grid is the
same size as the conduit beeing mesured.
Check for size on grid. (Figure 11.6)
Step 4: On this unit the airflow is regulated by a
balancing damper installed inside the ISFTM collar system
located on the top right side of the HRV. (Figure 11.1)
figure 11.3 Inserting Air flow grid in duct
Measure and regulate the «fresh air from outside»
damper until desired airflow volume. Repeat the same
steps for the «exhaust air from home» damper.
Step 5: Finish the balancing operation by tapping
all the holes made from the mounting of the airflow
grid. (Figure 11.5)
