display “CF” to signify “Condensate Full”. When this occurs, turn the On/Off
switch to the off position and unplug the float jack and condensate drain line from
behind the unit and drain the tank. Replace the tank, plug in the float jack and
drain line and turn the On/Off switch to the on position. The unit will return to its
previous settings in two minutes. The condensate tank is normally used only for
short-term applications. Note: If you do not turn the unit to the off position,
the unit will continue to sound the alarm until the float jack plug is
reinserted.
c. Safety Alarm – If the unit alarm “AL” is displayed, the unit will
automatically shut down and an audible alarm will sound. The “AL” display may
indicate low or high condenser pressure, or a condensate pump failure. Call
KwiKool (1-800-594-5665) for technical assistance.
d. Condensate Pump – All KwiKool models, except KPAC models, come
standard with an internal high lift condensate pump with a 20-foot head pressure.
The pump collects the condensation that forms on the evaporator coil into its
one-quart reservoir, during normal cooling operation. If the unit is required to
operate continuously, it is recommended to run a ¼-inch condensate line from
the nipple on the back of the unit to the nearest drain. The line can be run up the
same path as the ducting, then across the ceiling to a drain, up to 150 feet away.
The jack plug, located in the same package with the owner’s manual, must be
plugged into the hole just above the ¼-inch nipple. The insertion of the jack plug
will deactivate the condensate alarm by sending a message to the unit that a
condensate line has been run to a drain.
7. APPLICATION REQUIREMENTS
a. Air Temperature Requirements – The environmental requirements of your
KwiKool unit at the installation site are 60 to 110 degrees F for the intake
condenser air. If the unit is operated in an environment above this range, the
high head pressure switch will trip, stopping the unit’s compressor, which must
be reset by pressing the red button on top of the switch. Standard air-cooled
KwiKool models are not designed to operate at temperatures below 60
degrees F. Low-ambient temperature controls must be special ordered at
an additional cost. If the intake air for the front duct is taken from outside the
building, the unit will cause the unit to cycle excessively at temperatures below
60 degrees F. For split-system models the condenser section must be placed in
an area with ambient air temperatures above 60 degrees F. or the unit will cycle
excessively and damage the fan cycling switch.
b. Capacity & Temperature Settings – Sizing of our units is based on matching
capacity to a specific heat load while maintaining a 72-degree F. temperature. In
order to reach temperatures below 72 degrees F., the unit must have extra
capacity. Therefore, we recommend that you do not set the temperature set
point below 72 degrees F., unless you have excess cooling capacity, since
this may cause the unit’s coil to freeze up.
c. Condenser Intake/Exhaust Air Requirements – Two ducts attached to the
flanges on the top of the unit, are normally vented to a drop ceiling via the ceiling
kit. The rear top flange is for the condenser hot air exhaust and the front flange
is for the condenser intake air. The area above the ceiling must be open to the
rest of the floor or tied into duct, which leads to the outside. If the area above
the ceiling is sealed the pressure will back up into the unit and shut it
down, due to high head pressure. (See ceiling kit section c on page 4.)
