Condensation normally forms on the heat exchange core during the cold 
weather (below 29°F or -2°C). Moisture can build up when the warm air from 

your home comes in contact with the cold air from outside. The tray collects the 

moisture and funnels it to the drain. The drain pans are made of therrnoformed 
plastic for easy cleaning.

The built-in defrost mechanism will remove frost which can accumulate in colder 
weather (21°F [-6°C] and colder). The type of defrost mechanism used is known 

as “damper style”. This consists of an electronically controlled damper door 

(attached to a small electric motor) that moves to block off the outside cold air 
entering the ventilator. If the outside temperature drops below 27°F (-3°C), the 

defrost timer is activated. The timer activates the motor driven damper door 

mechanism which temporarily moves to close off the outdoor air supply and 
opens another port on the ventilator that allows warm indoor air to enter the core 

to help the defrost. Approximately three minutes after the defrost cycle is acti-

vated, the timer will signal the damper to return to its original position for a 
2.7 minute period. The defrost cycle will repeat until the outside temperature 

rises above 27°F (-3°C).

The cross flow heat recovery core transfers heat between the two airstreams. 

The core removes easily for cleaning or service.

Easy operation, simply rotate the Perfect Window™ ventilator fan speed control 

to your desired setting.
