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

CABINET
The OWC-QC 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
The OWC-QC is equipped with a deluxe electronic controller. When proper 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 the fan speed for manual or automatic.
In manual setting, the fan speed can be programmed to any of the six fan speed levels, from
(1) Low to (6) High. In auto setting, the unit will determine the best fan speed based on the
inside temperature and selected SETPOINT.
CONDITION ALARM—CON
The LED thermostat of the unit will display the fault "CON" which indicates a condition that
needs to be addressed.
CONDENSATE PUMP... Failed/Restricted drain tube/routed incorrectly
WATER SUPPLY............ Turned off/Interrupted flow
EITHER CONDITION WILL DISABLE THE COMPRESSOR
CONDENSATE PUMP
Each OWC-QC unit comes 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 quick connect 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
Normally Closed overflow switch will open, and the fault "CON" will display in the window.
When the failure has been corrected, or the condensate line blockage/kink has been re-
solved, the fault will be dropped from the screen, and the unit will restart.
HIGH PRESSURE SAFETY SWITCH
Located in the recessed area of the OWC-QC unit is a manual reset high pressure switch. It is
used for the protection of the compressor, in the event that the condenser water supply is
turned off. If the internal pressure exceeds the limit setting, the switch cycles off the com-
pressor, 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.
FILTERS
The OWC-QC unit is 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 CORD
The OWC-QC unit is equipped with a 10 foot power cord for convenience.
