User Manual

Press set again, the unit displays the room temperature. This is the default display
and the control will always reset to this display automatically.
This completes the “set” cycle routine.
e.
Time Delay - Protects your KwiKool from potential damage by delaying the compres-
sor from starting before the pressures in the mechanical system equalizes. Always
activates when your KwiKool cycles off, is turned off, or power is lost and then
restored.
High Pressure Alarm - Protects your KwiKool from potential damage to the
mechanical system by shutting down and alerting operators of a condition such as
stopped or slowed air flow over the condenser coil, make-up air temperature above
operating range or mechanical failure. Your KwiKool will sound an audio alarm only with
no fault light. To resume operation the system requires a manual reset after corrective
action is taken, the reset switch is located in the service door access on the compres-
sor discharge line. Push in to reset, if activated you will feel a click.
Low Pressure Alarm - Protects your KwiKool from potential damage to the
mechanical system by shutting down and alerting operators of the condition. This safety
activates when pressure below 20 PSI are detected in the mechanical system. Your unit
will sound an audible alarm only with no fault light. Call KwiKool at 1-800-594-5665 if
the alarm is present on start up. Automatic reset upon correction of the low pressure
condition.

Turn ON the System - Using the ON/OFF selector switch select to ON. The
evaporator fan starts and a 3 minute delay activates. This prevents the compressor
short cycling. After the time delay reaches 3 minutes the compressor starts and cooling
will begin. After the system has built up enough pressure the hot air exhaust fan will
start to ramp up, it is normal for this fan to delay in starting and also normal for it to
slow down and speed up downing the operating process. NOTE: The evaporator fan is
on continuously when the selector switch is in the ON position.
Cycling Off - After the system has reached its set point it will automatically cycle off
or you may choose to turn the system OFF by moving the selector switch to the OFF
position. If the unit cycles off or is turned off, the 3 minutes time delay will always
activate when the system calls for cooling. When cycling off by making the set point,
the evaporator fan stays on and cooling will begin automatically when the temperature
rises above the set point. Turning the system OFF manually will turn the evaporator fan
off and not allow the system to restart until the selector switch is set to ON and the
return air temperature is above the set point.
Installation Site - Preview your installation site, DO NOT place the KPO in the
space that you are cooling. Your KPO is designed to be placed outside the conditioned
space and ducted in. Before moving your KPO into place verity the following. The
direction you would like the supply and return air to go (cooling), the direction you
would like the hot air exhaust to go (heat removal), where will the condenser make-up
air coming form, where is your power supply located and where is the condensate
water pumping too? Position the unit based on these guidelines for best results. NOTE:
Leave at least 5’ of space open around the make-up air inlets for the condenser to
ensure proper operation.
