System trips breaker on
start up Incoming power is incorrect,
breaker is undersized or
faulty, and/or extension
power cable is too long and
or undersized. Verify the circuit and power
cable is within the systems
specifications, consult with
your electrician or call
1-800-KwiKool for
guidance.
System starts up and
operates in the chosen
mode but the condenser
discharge air exhaust fan
stops and starts in cool
mode or in heat mode the
supply air fan starts and
stops. Normal operating condition
especially in low tempera-
tures. No action required, see
sections IV C. 2 & 3
Note:
To avoid excessive
fan cycling, return air must
not be below the specifica-
tions of your KwiKool
system.
Supply air flow is limited, and
or water is dripping from the
front of the system Supply or return air is
blocked or restricted, and or
the evaporator coil is
freezing. Verify that supply and
return air are not blocked
and duct work is installed
to specification, remove or
add duct as needed, check
air filter for blockage.
Fault Possible Cause Possible Solution
Display shows 32 and unit
will not turn on cooling.
No connection of tempera-
ture sensor to Micropro-
cessor. Temperature
Sensor malfunction. Call 1-800-KwiKool for
instructions.
Condensate is not pumping. Water is below pumping
level, external line
restricted, line installed with
too high of lift. Reservoir fills, and then
pumps. Check for line
crimping or restrictions and
proper line run height. Refer
to the user guide Section 5:
Built in Safeguards.
Evaporator coil is freezing Low or restricted air flow.
Undersized capacity, unit
constantly on, unable to
achieve set point. Low
return air temperature out
of factory specifications.
Evaporator door open,
mechanical system
malfunction. Direct supply return air to
area of highest heat load,
check for blocked air flow
from the supply air, replace
air filters, adjust set point to
allow the unit to cycle, add
another KwiKool system or
larger capacity model, close
evaporator compartment
door. Install service gauges
to view pressures.
