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 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

A two position rocker switch, located next to 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 3/8 male flare connection located on the

back of the unit. The pump is capable of pumping to a 20-foot height, to handle almost

any installation requirement.

CONDENSATE ALARM LIGHT

On the front of all PWC models, there is a Condensate 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 electrostatic mesh

air filter is located behind the evaporator return air grille to filter the air before it is cooled,

keeping the coil free from dust build-up. The filter can be easily removed and cleaned.

HIGH PRESSURE SAFETY SWITCH

Located on the back 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 remains running, The high pressure switch is also wired in se-

ries with the condensate pump. If a failure occurs with the operation of the pump

circuit, the HP switch will open. Once the water interruption/condensate pump failure 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.

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.
