Maintenance and Service

Drainage

The base pan may overflow due to high humidity.

To drain the excess water, remove the drain cap

from the back of the unit.

Chassis

The chassis must be cleaned every four months or more often as the atmospheric conditions

require. Use water and detergent to clean the basepan, center partition 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.

Corrosion Resistant units operating in harsh atmospheric conditions must be removed from the

sleeve and cleaned every 3 months in the same manner as above.

Compressor / Fan Motor

The compressor and fan motor are hermetically sealed, permanently lubricated, and require no

additional oiling.

Cabinet Front

The cabinet front and discharge air grille can be cleaned with a mild soap or detergent. Under no

circumstances 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.

Corrosion Resistant Models

Corrosion resistant models subjected to harsh seacoast environments must be removed from the

wall sleeve and completely flushed with clean water at least four times a year. The basepan, center

partition, condenser end plates, and the condenser itself should be sprayed with clean, fresh water.

Leaving the unit in the sleeve and simply spraying the outdoor grille is not sufficient.
