Systems with phase
monitor starts up but go
into PH and audible
alarm when the com-
pressor starts.
Phase monitor detects volt-
age drop.
Observe the phase monitor on start for fault
lights and adjust accordingly, verify incoming
power. If no fault light is present see advanced
troubleshooting below
Power is supplied but
control is blank
Low voltage circuit is not
engaged
On 12 & 25 ton models turn on built in breaker,
all models verify incoming power to contactor,
reset switch on low voltage transformer
System starts up and
cools but hot air exhaust
fan speeds up and
slows down.
Normal operating condition
in cool mode, especially in
low temperatures
No action required review operations guide.
Cool air flow is limited,
water is dripping from
the front of the system
Supply or return duct is col-
lapsed, blocked or not in-
stalled, filters need to be
replaced and/or the evapo-
rator coil is freezing as a
result of the above.
Verify that supply and return duct are installed
to specification, remove or add duct as needed,
check air filter for blockage. Restart when
thawed.
Condensate is not
pumping
Water is below pumping
level. System is in fan or
heat mode
Reservoir fills, Check for line crimping. Con-
densate is not developed in heat or fan mode.
System sounds audible
alarm only and display
reads CP.
Mechanical system has de-
tected high water level in the
condensate pump. System
not level.
Level System
Inspect condensate pump for overflow and
proper operation
Check condensate line for clog or crimping.
Resets automatically upon correction.
Call 1-800-KwiKool.
Mechanical system has de-
tected high pressure.
Correct condition with air flow in or out of
the condenser:
Inspect/replace condenser drive belts
Check condenser motor for proper opera-
tion
Check condenser drive (VFD) for trip, reset
if needed
High-pressure switch requires manual reset.
The pressure switch is located in the service
compartment on the compressor discharge
line.
