KPO PORTABLE AIR CONDITIONERS KWIKOOL
17
If the unit operates in an environment above 110 degrees F, the high-pressure switch may trip,
stopping the unit’s compressor. Instead of the compressor stopping, the operator may also notice
diminished performance.
The High-Pressure Switch is a manual reset type and located in the front service compartment on
KPO5 and KPO12. The reset is in the return air compartment on the KPO25, and the system is
equipped with two reset switches.
Reset is accomplished by pressing the button on the switch located on the compressor discharge
line. If the switch has tripped, the operator will feel a distinct click upon reset.
B CAPACITY & TEMPERATURE SETTINGS
Sizing of the KPO units is based on matching capacity to a specific heat load while maintaining a 72-
degree F temperature. To reach temperatures below 72 degrees F, the unit must have extra capacity.
CAUTION
We recommend that the operator not set the temperature set point
below 72 degrees F, unless there is excess cooling capacity be-
yond the heat load, since this may cause the unit’s evaporator coil
to freeze up.
C POSITIONING OF UNIT
The unit should be positioned as close to the space to be conditioned as possible with the return air
duct directly around the area of highest load. Place the KwiKool system on a level surface to ensure
proper condensate water flow and be sure the surface can support the weight of the KwiKool.
CAUTION
Do not block the return air duct of the unit since this will cause low
performance and/or evaporator coil freezing while in cool mode.
