MAINTENANCE
32
Unit
The Unit must be cleaned every four months or
more often as the atmospheric conditions require.
Use water and detergent to clean the base pan and
coils. The use of harsh cleaning materials may
cause a deterioration of the coil fins or endplates.
Do not use a high pressure cleaner as it could cause
severe damage to the PTAC fins and coils. A hose is
okay to use to clean the coils, but make sure to
cover the control with a blanket or plastic bag to
keep it dry.
Compressor and Fan Motor
The compressor and fan motor are hermetically
sealed, permanently lubricated, and require no addi-
tional oiling.
Front Grille
The Front Grille and discharge air grille can be
cleaned with a mild soap or detergent. Under no cir-
cumstances should hydrocarbon based cleaners
(e.g. acetone, benzene, naphtha, gasoline, etc.) be
used to clean the front or air grilles.
Use care when cleaning the control area. Do not use
an excessively wet cleaning cloth.
