new construction. Plan the installation carefully before you
begin. Listed below are some guidelines that should be fol-
lowed when determining location for the unit.
1. Place unit adjacent to an outside wall if fresh air is
required, ensuring that location allows for complete
air distribution.
2. Locate the thermostat in an area that is not subjected
to drafts or direct sunlight through windows. Locate
the thermostat on an internal wall whenever possible.
3. Allow sufficient clearance for airflow, wiring, refriger-
ant piping, and servicing unit (Fig. 3 and 4).
4. Make sure the unit is easily accessible to electrical
power.
