Automatic Restart - In the event of a power loss your KwiKool resumes operation
when the power is restored if in the ON position. All operational functions are
preserved in the memory of the control.
Condensate Pump & High Level Alarm - KPO systems are factory equipped
with an internal high lift condensate pump. KwiKool condensate pumps are able to
pump the condensation collected in the reservoir of the pump to a drain or other area
approved for the discharge water by attaching 1/4” I.D. tubing to the 1/4” O.D. barbed
condensate outlet, located as you are facing the control on the left upper portion of the
condenser inlet on the 12-ton models and next to the power cable connection to the
cabinet on 5-ton models. KwiKool condensate pumps are able to pump 20’ vertical and
are equipped with a pump safety cut-off that prevents accidental water overflow by
shutting your unit down and alerting operators with an audible alarm only with a no fault
light. Call KwiKool at 1-800-594-5665 if this alarm is present on start up. The most
common reason for this alarm to activate during operation is restricted water flow
through the discharge tubing or excessive discharge line connected to the system.
Automatic reset upon correction of the condensate flow.
Power/Phase Monitor - Standard on all 3-Phase KPO models. The power monitor
samples the power supply and shuts down and alerts operators with an alarm and red
fault light displays in the event of low or high voltage, incorrect voltage, incorrect
phasing or motor fault. The monitor is factory set to reset automatically upon adjust-
ment of the monitor or correction of the issue indicated on the monitor. The monitor is
located in the electrical control panel of your KwiKool unit and displays the reason for
activation. See the Troubleshooting Guide (section X) in this manual for adjustment
detail if your KwiKool Phase Monitor is alarming and displaying fault lights.
VFD (Variable Frequency Drive) - Used on KPO systems to optimize the
operation of the condenser fan in low ambient conditions by slowing down and speed-
ing up the condenser blower. This helps to maintain the best pressure needed to
operate in your current environment. Your VFD is located in the cold-air return air
compartment for the 12-Ton and in the condenser access compartment on the 5-Ton
and displays the current operating frequency or any error message needed for fault
diagnosis.

Air Temperature Requirements - The environmental requirements of your
KwiKool unit at the installation site are 60 to 110 degrees F for the condenser make-up
air located on each side of the unit. If the unit is operated in an environment above
110 F the high pressure switch may trip stopping the unit’s compressor, or you will
notice diminished performance. The High Pressure Switch is manually reset, the reset
switch is located in the service compartment, Reset is accomplished by pressing the
button on the switch located on the compressor discharge line. If the switch has
tripped, you will feel a distinct click upon reset. Standard KwiKool KPO models are not
designed to operate at temperatures below 60 degrees F. on the cooling side.
Temperatures below 60 degrees F will cause evaporator coil freezing.
Capacity & Temperature Settings - Sizing of our units are 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,
