STANDARD FEATURES
CABINET
The PWC-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 sound- absorbing insulation for cool, quiet comfort. All units come
equipped with handles and swivel casters for portability and convenient set-up.
ELECTRONIC THERMOSTAT
All PWC units are equipped with a non-
programmable electronic thermostat. When power is connected to the unit, the thermo-
stat 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 continuous-
ly. 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
A two position rocker switch, located near the thermostat,
provides the user with the option of running the evaporator fan at high-speed or
low-speed.
CONDENSATE PUMP
All PWC units come equipped with an Automatic Condensate
Pump that removes the condensate. The pump discharges through a check valve located
on top of the condensate pump assembly. The vinyl tubing exits through a 3/8” male flare
fitting, located in the recessed area of the unit. The pump has capabilities up to a 20’ lift,
to handle almost any installation requirement. If a failure occurs with the operation of
the pump circuit, the
NC overflow switch
will open, and the CONDENSATE ALARM warn-
ing light will energize. When the failure has been corrected, or the condensate line block-
age/kink has been resolved, the alarm light will clear, and the unit will restart.
CONDENSATE ALARM LIGHT
On the front of all PWC models, there is a Conden-
sate Alarm Light (RED) located near the thermostat. The light indicates a condensate
pump over-flow condition where the pump is either disabled, or incapable of removing
the condensate water, and must be serviced.
FILTERS
All PWC units are equipped with a washable filter at the air intake. An elec-
trostatic mesh air filter is located behind the evaporator return air grille to filter the air
before it is cooled, keeping the coil free from debris. The filter can be easily removed and
cleaned.
HIGH PRESSURE SAFETY SWITCH
Located near the hose fittings of the PWC
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 switch cycles off the compressor, while the evaporator fan
continues to operate. Once the water interruption has been corrected, turn the unit off,
RESET THE RED BUTTON
by pushing down on the rubber boot in the recessed area of the
unit, listening for the click, and restart the unit.
POWER CORDS
All PWC units come with power cords, convenient connection and
portability. All models, except for the 3-phase and 5-ton units, are equipped with LCDI for
added safety devices.
