STANDARD FEATURES
CABINET
The OWC-Series cabinet is constructed of 18 gauge steel with a gray polyester powder
coated finish that will compliment any decor. The entire cabinet is insulated with a sound-
absorbing insulation for cool, quiet comfort. All units come equipped with swivel casters
for portability and convenient set-up.
ELECTRONIC THERMOSTAT
All AQUACOOLER units are equipped with a non-programmable electronic thermostat.
When power is connected to the unit, the thermostat will control the unit to cool a space to
the desired temperature. The thermostat is also capable of controlling the fan to operate
automatically (when needed) or continuously. To protect the compressor from short-
cycling, there is a built-in time delay in the thermostat. In the event of a power outage, all
thermostat settings are saved, and the unit will re-start automatically.
FAN SPEED CONTROL
The electronic thermostat is capable of setting fan speeds automatically or manually. In
AUTO mode, the fan speed adjusts in according to cooling conditions. In MANUAL
mode, the fan speed can be maintained at a one of six speed levels, from low to high.
CONDITION ALARM—CON
The LED thermostat of the AQUACOOLER will display the word “CON” , indicating a fault
condition in the controller. CON indicates that there is a condensate condition that needs
to be addressed or the high pressure switch has been tripped. For models less than 5-
tons, the CON indicates that the condensate tank is full and needs to be emptied. In the 5
-ton AQUACOOLER units (model OWC60) CON indicates a condensate pump over-flow
condition where the pump is either disabled, or incapable of rejecting the condensate
water, and must be serviced. For the high pressure switch, see below.
CONDENSATE PUMP
All AQUACOOLER units come equipped with an Automatic Condensate Pump that dis-
poses of the condensate. The pump discharges through a 3/8 male flare DRAIN connec-
tion located on the back of the unit. The automatic pump is capable of a 20ft lift, to han-
dle almost about any installation requirement.
HIGH PRESSURE SAFETY SWITCH—CON
Located on the back of the AQUACOOLER unit is a manual re-set high pressure switch,
used for the protection of the compressor in the event that the condenser water supply is
turned off. If the condensing pressure exceeds the limit setting, the cut-out shuts down
the compressor, while the evaporator fan remains running, and “CON” will display on the
controller. Once the water interruption has been corrected, turn the unit off, reset the
switch by depressing the red RESET button on the back of the unit, and restart the unit.
FILTERS
All AQUACOOLER units are equipped with washable a filter at the air intake. Electrostatic
mesh air filters located behind the evaporator return air grill serve to filter the air before it
is cooled, keeping the coil free from dust build-up. The filters can be easily removed and
cleaned.
POWER CORDS
All AQUACOOLER units come with power cords, convenient connection and portability.
All units except the 5-ton models, and 3-phase models are equipped with LCDI for added
safety devices.
