KOLDWAVE 3AK (AIRMASTER)
CHECKOUT OF UNIT OPERATION
Koldwave Airmaster portable spot cooler
provides fan-only circulation and cooling
modes. This is accomplished by setting the
controls to operate in any of the following
positions:
FAN ONLY
Plug unit in, Depress the upper mode
selector rocker switch to the left for fan
operation. Rotate the lower fan speed
selector switch to the right for low fan speed,
to the middle for medium speed and to the
left for high speed.
COOLING CYCLE
The green-colored pilot light will illuminate
when mode selector rocker switch is
depressed to the left or right, indicating there
is power to the control panel.
The blue-colored light, indicating the cooling
mode of operation, will illuminate when the
upper mode selector switch is depressed to
the right and the thermostat calls for cooling.
When the blue light is on, the compressor,
and the condenser and evaporator blowers
will be running. Allow the unit to run with fan
speed set on high for twenty minutes and
then turn the thermostat to the desired set
point.
Note the temperature of the air entering the
filter and the temperature of the air leaving
the discharge grille. In a room of 85°F dry
bulb 50% relative humidity, the air
temperature coming from the grille should
be approximately 15°F cooler than the air
returning to the filter.
The red-colored light located below the
blue-colored light will illuminate when the
condensate tank is full. Refer to the
condensate reservoir tank on page 7.
TROUBLESHOOTING GUIDE
SERVICE PROCEDURES
Before troubleshooting this system, read this manual
to determine electrical power and installation
requirements to allow the spot cooler to perform at its
maximum efficiency. Refer to general description,
wiring diagrams and photographs to get an
understanding of how the unit functions.
Service other than routine maintenance should be
performed only by a qualified refrigeration service
person. In service/troubleshooting, there is no
substitute for a good understanding of the Koldwave
Airmaster modes of operation, control systems,
components and safety systems (see service
performance chart).
SYSTEM PERFORMANCE CHART
The chart below shows suction and discharge
pressures (PSIG), plus total amp draw with evaporator
fan on high speed, with condenser motor on high
speed and with condenser blower baffle. The
condenser discharge air is ducted into another area
with a 12" diameter, 10' long flexible duct.
