VIII. Simple Troubleshooting
Failure
Machine turned on but
unelectrified
Flow Alarm, connecting the
water outlet and inlet with a
water pipe directly, but still
no water flow
Flow alarm occurs while
chiller is working. However,
when the water outlet and
inlet of the chiller are
connected directly with a
water pipe, water flows and
no alarm occur.
Ultra-high water
temperatureal alarm
Ultra-high room
temperaturealarm
Serious problem of
condensate water
Water drains slowly from
drain port during water
changing
Startup flow alarm
Failure Cause
Power cord is not plugged
in place
Fuse burnt-out
Water level in the water tank
is too low
Water circulation pipes are
blocked or a pipe is bent or
deformed
Blocked dust gauze, bad
thermolysis
Poor ventilation for air outlet
and inlet
Voltage is extremely low or
unstable
Improper parameter settings
on thermostat
Switch the power on and off
frequently
Excessive heat load
The working ambient
temperature is too high for
the chiller
Water temperature is much
lower than ambient
temperature and the
ambient humidity is high
Water supply inlet is not
open
Bubble in the water pipe

Approach
Check and ensure the power interface
and the power plug is plugged in place
and in good contact.
Pull out the fuse box from the power
supply interface of the chiller, check the
fuse, replace with spare
necessary, and check whether the
power supply voltage is stable. Check
and ensure the power interface and the
power plug is plugged in place and in
good contact.
Check the water level gauge display,
add water until the level shown in the
green area; And check whether the
water circulation pipe leaks.
Check the water circulation pipe.
Disassemble and clean the dust gauze
regularly.
Ensure a smooth ventilation for air outlet
and inlet.
Improve the power supply circuit or use a
voltage regulator.
Reset the controlling parameters or
restore the factory setting.
Ensure sufficient time for refrigeration
after starting the chiller (at least 5
minutes).
Reduce the heat load or use other model
with larger cooling capacity.
Improve ventilation and ensure that the
machine is operated below 40°C.
Increase water temperature or insulate
pipes.
Open the water supply inlet
Exhaust the air
