Installed location must be at least a 10' x 10' x 7' room (700 cubic feet of air space). If smaller, there must be louver installed to provide sufficient airflow.

Installed room location must not be cooler than 40°F.

Installed locations with warmer ambient air temperature (i.e. furnace room) provides abundant "free" heat and is advantageous.

The heat pump dehumidifies the air and as a result produces condensate which must be piped to drain or outdoors.

The washable air filter requires periodic cleaning. Frequency depends upon environmental conditions.
