MAINTENANCE Performing preventative maintenance (PM) helps to keep your nVent HOFFMAN AC unit operating at the highest most efficient levels. Maintenance should be performed at least twice a year, more frequently when in challenging conditions, such as dusty, high humidity, high heat, oily or corrosive environments.
Inlet air filter Proper maintenance of the inlet air filter, located behind the front cover, will assure normal operation of the air conditioner. If filter maintenance 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 filter (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.
CONDENSER AND EVAPORATOR AIR MOVERS Fan and impeller motors require no maintenance. All bearings, shafts, etc. are lubricated during manufacturing for the life of the motor. CAUTION Operation of the air conditioner in areas containing airborne caustics or chemicals can rapidly deteriorate filters, condenser coils, blowers and motors, etc.
