CABINET
The OWC1811QC 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 OWC1811QC 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 OWC1811QC unit comes equipped with an Automatic Condensate Pump that removes
the condensate. The pump discharges through a check valve located on top of the conden-
sate pump assembly. The vinyl tubing exits through a ¼" male quick connect fitting, located
in the recessed area on the right side 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 dis-
play in the window. When the failure has been corrected, or the condensate line blockage/
kink has been resolved, the fault will be dropped from the screen, and the unit will restart.
HIGH PRESSURE SAFETY SWITCH
Located in the recessed area of the OWC1811QC 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
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.
FILTERS
The OWC 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 OWC1811QC unit is equipped with a 10 foot (5-15P) power cord for convenience, and has
a LCDI device for added safety.
