Description
•
Heat Recovery Core
:
A polypropylene cross-flow
type it is designed to transfer the heat between
both exhaust & supply air streams without
allowing any contamination or mixing of both air
streams to maximize the efficient and improve
your indoor air quality.
•
Condensate Drain Pan & Drainage Hose
:
Captures the water that accumulates during
the heat transfer and defrosts sequence in
the fall, winter & early spring seasons. Drain
hose is connected to the drain pan and serves
as drainage for the accumulation of water. It
is normal during summer months to find no
condensation in drain pan or in drainage hose.
•
Automatic Defrost Sequence
:
The ERV and HRV
units are equipped with an automatic defrost
feature to eliminate any ice build up on the core.
Automatic defrost is initiated once every hour
when the fresh air supply temperature drops to
23°F (-5°C) or colder.
- The defrost cycle operates by turning off the
supply fan while continuing to operate the
exhaust fan.
- The exhaust fan speed is adjusted
proportionally based on the outdoor
temperature, initially operating at low speed.
- As the outdoor temperature continues to
drop, the exhaust fan speed will increase,
and will operate at maximum speed when
the outdoor temperature is -4°F (-20°C) or
less.
- Defrost cycle runs for 4 minutes with the
supply fan off, followed by 40 minutes of
continuous normal operation.
- Defrost cycles will continue to repeat as long
as the temperature is 23°F (-5°C) or less.

•
Fresh Air from Outside Port (A)
:
Inlet for fresh
outdoor air.
•
Exhaust Air to Outside Port (B)
:
Outlet for
exhausting stale, humid and contaminated air
to the outdoors after transferring its heat to the
recovery core.
•
Exhaust Air From Home Port (C)
:
Exhausts stale,
humid and contaminated air to the outside from
multiple location of the home or from the return
air of the forced air system, prior to passing
threw the heat recovery core. Ex: Bathroom,
laundry room, etc.
•
Fresh Air to Home Port (D)
:
Introduces &
distributes clean & fresh air to your home. The
homes fresh air ports are normally installed in
the main living areas or in the return/supply
duct of the forced air system. Ex: Living room,
bedrooms, recreation rooms, etc.
•
Control Panel
:
Selects your ventilation modes
(OFF, CONT or INTER), also to adjust your
continuous airflow rates: Increasing (+)/
Decreasing (-).
•
Synthetic Filters
:
Capture the largest particle and
protects your heat recovery core from potential
obstruction by these particles.
