3.0 Description of the Unit
1) Stale air intake port:
is connected to the registers located in the larger
rooms of the house.
2) Fresh air port:
brings fresh air from the outside into the unit.
3) Exhaust port:
exhausts stale air to the outside, 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) Foam filter:
traps the dust contained in the air and prevents the heat
recovery core from becoming obstructed.
6) Heat recovery core:
is a counterflow type for 2000 HE, 3000 HE, 1.8 HE,
2.6 HE models and is a crossflow type for the other
models. It transfers the heat between the two air
streams.
7) Blowers:
draw fresh air from the outside and exhaust stale air to the outside.
The blower wheels are driven by two motors for 2000 HE, 3000 HE,
1.8 HE, 2.6 HE models. The other models have just one motor.
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 control circuit:
located inside the electrical box, insures
proper operation of the unit.
12) Automatic defrost unit:
consists of one damper actuator, dampers and the
related controls. The defrost cycle is electronically
controlled in response to the outside 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:
located inside the electrical box, allows to connect the
control and override switch as a timer, a dehumidistat
or a switch.
14) Electrical cord:
for 120V electrical supply.
