CAUTION

Make sure at all times that the outside intake and exhaust hoods are free
from any snow during the winter season. It is important to check your unit
during a big snow storm, so it doesn’t draw in any snow. If this is the case,
please operate the unit in recirculation mode, or turn it OFF for a few hours.
Do not use your unit during construction or renovation of your house or
when sanding drywall. This type of dust may damage your system.
Since the electronic control system of the unit is incorporated with a
microprocessor, it may not operate correctly because of external noise
or very short power failure. If this happens, unplug the unit and wait
approximately 10 seconds. Then, plug the unit in again.

When the outside temperature is below 23°F (-5°C), recovery of heat or energy
creates frost in the core.

To maintain its proper operation, the unit is programmed to defrost the recovery
core. The defrost frequency varies according to the outside temperature.

During the defrost cycle, the unit shifts to maximum speed and the dampers close.
After defrosting, the unit returns to the operating mode selected by the user.
