• If practical, place the air conditioner where it
and the ducts will be shaded from the afternoon
sun when the heat load is greatest.
• Try to select a site for the unit that is as close
as possible to the proposed return grille loca-
tion.
• Keep in mind that the length of the supply and
return ducts should be kept to a minimum with
no sharp radius bends.
2. UNPACKTHE UNIT
It is recommended that the unit be unpacked
at the installation site to minimize damage due
to handling.

tures to provide room for proper servicing
and air circulation.

area that will allow discharge air from the unit
to re-circulate into the condenser air inlet,
through the coil.

DUCT REQUIREMENTS
The supply duct system, including the number
and type of registers, will have much more ef-
fect on the performance of an air conditioning
system then any other factor. The duct must be
sufficiently large to conduct an adequate amount
of air to each register.
