KOLDWAVE 2AK (AIRMASTER)
CABINET
The Koldwave Airmaster cabinet is constructed of 20
gauge, cold rolled steel with painted steel finish for
corrosion protection. It is lined with thermal and sound
absorbent insulation material in the discharge area
and vibration dampening on all panels.
SAFETY ENGINEERED
In addition to the rotary compressor’s overload
protection, Koldwave Airmaster incorporated, within
the refrigeration system a manual reset high pressure
switch for maximum safety of the compressor. The cut-
out pressure setting is 375 ±10 psig. In the event that
the high pressure switch setting is exceeded, the
compressor and condenser fan operation will cease.
The compressor and condenser fan can be restarted
by depressing the “reset” button located on the back
panel of the unit.The high pressure switch capillary
line screws onto an access valve on the refrigeration
discharge line to make it possible to remove or replace
a defective control without disturbing the refrigeration
system.The unit also employs an automatic reset
freeze control, located on top of condenser coil, to turn
the entire unit off at low ambients and defrost the
evaporator coil for approximately five minutes.
NOTE:Wait two minutes before restarting unit after
tripping by one of the safety features.

RELIABLE CONTROLS
The self-contained unit maintains the desired amount
of cooling, which can be selected by adjusting the
thermostat to warmer or cooler.The thermostat
sensing bulb is in the return air stream behind the
louvered return air grille and return air filter.The range
of the thermostat is from 65-100°with a differential of
±3°F.
The three-position, mode selector rocker switch,
located in the front panel, has three functions:
1. To provide fan only operation when depressed to
the right.
2. To turn the unit off when set in the center position.
3. To activate the cooling mode when depressed to
the left.
The blue colored light above the thermostat indicates
the thermostat is calling for cooling mode operation.
Compressor may or may not be on, depending on the
thermostat setting. The red, “tank full” warning light
indicates condensate tank is full and needs to be
emptied.The two-position, fan-speed rocker switch,
located below the mode selector switch, provides high
fan speed when depressed to the right and low speed
when depressed to the left.
