3 Exhaust
port:
exhausts stale air to the outdoors, after the air has transferred
its heat inside the heat recovery core.
4 Distribution
port:
distributes fresh air into the house, after it has absorbed the
heat of the stale air in the heat recovery core.
5 Mechanical
filters:
trap the dust contained in the air and prevent the heat recovery
core from becoming obstructed.
6 Heat recovery core:
is a counterflow type. It transfers the heat between the two air
streams.
7 Blowers:
draw fresh air from outdoors and exhaust stale air to
outdoors. The blower wheels are driven by two motors.
8 Capacitor:
is indispensable to proper motor operation.
9 Condensation
tray:
is used to capture the water produced during heat transfer and
defrost (in cold climate).
10 Drainage tube:
is connected to the condensation tray and serves to drain the
water
within.
11 Electronic circuit:
located inside the electrical box, insures proper operation of
the
unit.
12 Automatic defrost unit:
consists of one damper actuator, dampers and related
controls. The defrost cycle is electronically controlled in
response to the outdoor temperature (-5°C [23°F] to -40°C
[-40°F]) and will increase in frequency as the temperature
decreases. Its duration is of 5 or 6 minutes according to models.
13 Control connector:
