doors.

the 4 screws fastening the cover in place.
3. Disconnect the motor wires coming through the
bottom of the electrical box from the circuit
board, capacitors and relays, and remove from
the electrical box.
4. Pull motor wires for lower blower through hole
in blower divider panel.
5. Disconnect damper motor wires (three) from
the circuit board and remove from the electrical
box.

remove from electrical box.
7. Remove the 4 screws securing the electrical box
to the cabinet of the HRV.
8. Remove the ground continuity screw from both
the upper and lower blower pans securing them
to the pan stops.
Damper Removal:
1. Cut cable tie fastening thermistor wire to
bracket, disconnect thermistor from circuit, and
remove thermistor.
2. On the damper motor, loosen the two set
screws which hold the square damper rod in
place using a 1/8” hex key.
3. Remove the machine screw and keps nut
fastening the damper motor to the bracket.
4. Remove the damper motor from the bracket
and ensure that the two shims are collected
from either side of the damper rod, and by
pulling the damper motor wires out from the
top core support panel.
5. Remove the plastic snap bushing from the hole
in the top core support panel where the damper
wires were removed from, and install a snap
plug to seal the hole, found in the manual bag.
Reinstalling the Damper Motor:
1. On the opposite side of the HRV, place the
damper motor over the square damper rod
aligning the end of the rod flush with the
damper motor.
2. Install the machine screw and keps nut which
fastens the damper motor to the bracket.
3. Insert the shim around the damper rod
ensuring it is placed on the opposite side of the
rod from the set screws. Both set screws
should screw directly into the damper rod, not
the shim.
4. Prior to tightening the set screws ensure proper
alignment of the damper door such that it is
evenly spaced over the port collars providing a
good seal in both directions.
5. Once alignment is confirmed, tighten the set
screws to secure the damper into place.

core support panel and install a plastic snap
bushing in hole.
