KWIKOOL KPO PORTABLE AIR CONDITIONERS

F AUTOMATIC RESTART
In the event of a power loss, the KwiKool resumes operation when the power is restored if in the ON
position. All operational functions are saved in the memory of the control.
G CONDENSATE PUMP & HIGH-LEVEL ALARM
KPO systems are factory-equipped with an internal high lift condensate pump. KwiKool condensate
pumps can pump the condensation collected in the reservoir of the pump to a drain or other area ap-
proved for the discharge water by attaching ¼” I.D. tubing to the ¼” O.D. barbed condensate outlet.
KwiKool condensate pumps have a pump safety cut-off that prevents accidental water overflow by shut-
ting the KwiKool down and alerting operators with an audible alarm and displaying CP on the control
panel. Call 1-800-KWIKOOL if this alarm is present on initial startup.
The most common reason for this alarm to activate during operation is restricted water flow thru the
discharge tubing due to crimping or clogging, or there could be too much length in the discharge line
connected to the system. There is an automatic reset upon correction of the condensate flow. If this
alarm is engaged the system will not operate in COOL, FAN or HEAT mode.
H POWER/PHASE MONITOR
Standard on all KwiKool KPO products. The power monitor samples the power supply and shuts down
the KPO and alerts operators with an alarm, PF displays on the control, and a red fault light displays on
the monitor in the event of low or high voltage, incorrect voltage, incorrect phasing, or motor fault.
1. The monitor is factory set to reset automatically upon adjustment of the monitor or correction of the
issue indicated on the monitor. The monitor is in the electrical control panel of the KwiKool and dis-
plays the reason for activation.
2. Clear the blinking fault history light by pressing and holding the fault button for 3 seconds.
3. See the troubleshooting guide for adjustment details if the KwiKool phase monitor is alarming and
displaying faults. If this alarm is engaged the system will not operate in Fan, Cool or Heat mode.
I VFD-VARIABLE FREQUENCY DRIVE
Used on KPO systems in COOL Mode to optimize the operation of the condenser fan by slowing down
and speeding up the rotations of the blower. This helps to maintain the best pressure needed to oper-
ate in the current environment. The VFD is in the supply return air compartment on KPO5 and KPO12.
On KPO25 systems it is in the condenser motor compartment. The VFD displays the current operating
frequency, or any error message needed for fault diagnosis. The condenser motor VFD will not operate
the condenser fan in HEAT or FAN mode, as it is not needed for these modes.
SECTION VI APPLICATION REQUIREMENTS
A AIR TEMPERATURE REQUIREMENTS COOL MODE
The environmental requirements of the KwiKool unit at the installation site are 0 to 110 degrees F for
the condenser make up air located on each side of the unit. Standard KwiKool KPO models are not de-
signed to operate at temperatures below 60 degrees F. on the cooling side. Temperatures below 60
degrees F. will cause evaporator coil freezing.
