Standard Features - OCEANAIRE OWC Series Engineering, Installation And Service Manual

CABINET
The OWC-Series cabinet is constructed of 18 gauge steel with a gray and blue 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 swivel
casters for portability and convenient set-up.
DELUXE ELECTRONIC CONTROLLER
All OWC units are equipped with a deluxe electronic controller. 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 deluxe electronic controller is capable of setting fan speeds automatically or manually.
In AUTO mode, the fan speed adjusts in accordance to cooling conditions. In MANUAL
mode, the fan speed can be maintained at any one of six speed levels, from low to high.
CONDITION ALARM—CON
The LED thermostat of the OWC will display the word "CON". CON indicates a fault
condition that needs to be addressed:
CONDENSATE PUMP...disabled / restricted drain tube/routed incorrectly
WATER SUPPLY..........turned off / interrupted flow
EITHER CONDITION WILL TRIP THE HIGH PRESSURE SAFETY SWITCH. See below.
CONDENSATE PUMP
All OWC units come equipped with an Automatic Condensate Pump that removes the
condensate. The pump discharges through a 3/8 male flare DRAIN 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.
HIGH PRESSURE (HP) SWITCH
Located in the recessed area of the OWC 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 compres-
sor, while the evaporator fan remains running, and the default "CON" will display on the
controller. The high pressure switch is also wired in series 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.
FILTERS
All OWC 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.
POWER CORDS
All OWC units come standard with a 10 foot power cord for convenience. All models, except
for the 3-phase units and 5-ton units, are equipped with an LCDI device for added safety.
