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 ������� most
applications. Should you decide ������� necessary in your application, regular maintenance to clean this
���= will assure normal operation of the air conditioner. The easily removable inlet ������� located behind the
louvered grille. If necessary ���������= is delayed or ignored, the maximum ambient temperatures under
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 ���= or coil has been cleaned. It is recommended that power to
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����� or
condenser coil, thus causing a reduction in cooling air ��= across the surface of the compressor and condenser
coil.
HOW TO REMOVE, CLEAN OR INSTALL AN OPTIONAL INLET AIR FILTER
Aluminum washable air ����� e designed to provide ex��������� ��ciency with a high dust holding
capacity and a minimum amount of resistance to air ��. Because they are constructed entirely of aluminum
they are lightweight and easy to service. To achieve maximum performance from your air handling equipment, air
�������= be cleaned on a regular basis.
The inlet air ���= is located behind the front louvered grille. To ��������° , �������� up and out of
retaining tabs in the bottom of the front louvered grille. �����= may now be cleaned or a new ��������K
Cleaning Instructions:
1. Flush �����= with warm water from the exhaust side to the intake side. DO NOT USE CAUSTICS.
2. ��������������= to drain. Placing it with a corner down will assure complete drainage.
CONDENSER AND EVAPORATOR AIR MOVERS
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.
Operation of the air conditioner in areas containing airborne
caustics or chemicals can rapidly deterior������= condenser
coils, blowers and motors, etc. Contact nVent Equipment
