4-23. CONDENSER AIR DISCHARGE LOUVER AND LINKAGE
This louver is automatically operated by a refrigerant pressure actuated cylinder and a push-pull cable. The
louvers open as refrigerant pressure in the condenser coil increases. This causes the louver to open more fully
to increase the flow of cooler air across the condenser coil.
a. Access.
(1) Disconnect power at power source.
(2) Remove the top rear cover.
b. Clean/Inspect.
(1) The louver can be cleaned with a soft brush or washed with water and a mild detergent solution.
(2) Check the louvers for bent blades, missing or damaged gaskets, and missing hardware or bearings.

(2) Loosen mechanical post screw.
(3) Close condenser louvers,
(4) Pull wire tight and tighten mechanical post screw.
5. Louvers must be tightly closed when air conditioner is off and head pressure is below 150 psig (10.516
kg/cm  2).
