KOLDWAVE 2AK (AIRMASTER)
PREVENTATIVE MAINTENANCE
Always disconnect power and discharge capacitors
before servicing. Koldwave Airmaster portable zone
cooler has been designed to give maximum
performance and reliability with minimum
maintenance. Maintenance of the system is
concentrated in three areas covered as follows.
Blower Motors
The only required maintenance to the condenser and
evaporator blower motors is to oil them annually. This
can be accomplished by following these simple steps:
1. Remove left hand side panel to gain access to
condenser blower motor. Access can be attained to
the evaporator blower motor by removing the front
panel.
2. Remove yellow oil plugs form oil ports.
3. Add 30 drops (1/5 teaspoon) SAE 20 non-detergent
oil into the ports.
4. Replace yellow oil plugs.
Filters
The life of a filter depends entirely on its environment
and use. It is recommended that air filters be inspected
on a regular basis every five to six weeks. A clogged
filter will cause the unit to operate at greatly reduced
efficiency. This unit employs two 1/2" thick, washable,
aluminum mesh air filters located beneath the louvered
front (evaporator) panel and beneath the back
(condenser) panel. The evaporator filter can easily be
removed and cleaned; just pull filter end cap at bottom
of filter and slide out. The condenser filter is removed
by holding tab at bottom of filter, lifting and pulling
toward you and down. The filters must be washed
periodically when needed. This may be done as follow:
1. Soak filter in solution of warm water and detergent
for 15 minutes.
2. Rinse in clean, hot water and shake excess
moisture from filter.
3. Spray one side of filter with light film of oil.
4. Reinstall with oiled surface facing out from unit.
Condensate Pump (optional)
The condensate pump is located in the lower front
section of the unit. To gain access to condensate
pump, open access door on right hand side of unit.
The pump motor requires oiling every six months with
SAE 20 non-detergent oil. The pan beneath the
condensate pump should be cleaned when mineral
deposits are visible. A clean pan will prolong the life of
the pump and its operation.
