FREE AREA — is the opening that remains in a grill or louvered
panel after the restrictions are taken away. For example, an
opening of 10 x 20 inches has 200 square inches. When this
opening is covered with a grill that is 56 percent open, the
FREE AREA is (200 x .56), 112 square inches.
Expanded and perforated metal grills in general vary from 30
percent to 60 percent open. Be certain that 460 square inches
of FREE AREA is available to the face of the condenser.

EXAMPLE OF HOW TO DETERMINE FREE
AREA OR % OPEN AREA:
TOTAL AREA = 8 X 8 = 64
FREE AREA = 2 X 2 X 9 openings
=36
% OPEN AREA = = 56%
NOTE: Service access must always be supplied either as
clearance or as a defined access panel.
CLEARANCES
The air conditioning unit clearances depend on:
1. Inlet air access used;
2. Discharge air duct arrangement;
3. Return air duct;
4. Storage compartment location and design.
A one (1) inch clearance is required on three (3) sides of the
air conditioner if the top return is used. When using the side
access for return, please allow a minimum of eight (8) inches
for the return air duct. Access to the electrical connections
must be provided when making the installation.
EVAPORATION SECTION
INLET AIR
The evaporation section must have free access to room air.
A minimum of 128 square inches of FREE AREA opening is
required. Where the return air must be provided through
louvers or mesh screen, the FREE AREA percentage of the
material used shall be taken into consideration when making
this determination. An example of how to determine FREE
AREA is included under "CONDENSER SECTION".
Electrical box access required.
