MAINTENANCE

COMPRESSOR

The compressor requires no maintenance. It is hermetically sealed, properly lubricated at the factory and should
provide years of satisfactory operating service.

INLET AIR FILTER (FIELD INSTALLED OPTION)

This air conditioner was designed with a dust resistant condenser coil. This allows it to be run �������
applications. Should you decide �������

which the unit is designed to operate will be decreased.
If the compressor's operating temperature increases above designed conditions due to a dirty or clogged
��� (or plugged condenser coil), the air conditioner's compressor will stop operating due to actuation of the
thermal overload cut-out switch located on the compressor housing. As soon as the compressor temperature
has dropped to within the switch's cut-in setting, the compressor will restart automatically. However the above
condition will continue to take place until the ���
the air conditioner be interrupted intentionally when abnormally high compressor operating temperature causes
automatic shut-down of the unit. The above described shut-down is symptomatic of a clogged or dir�����
condenser coil, thus causing a reduction in cooling air �� across the surface of the compressor and condenser
coil.

Impeller motors require no maintenance. All bearings, shafts, etc. are lubricated during manufacturing for the life
of the motor.
If one of the condenser impeller motors (ambient impellers) should fail, it is not necessary to remove the air
conditioner from the cabinet or enclosure to replace the blower. The condenser blower is mounted on its own
bracket and is easily accessible by removing the louvered grille.
