VIII. Simple Troubleshooting
Failure
Failure Cause
Approach
Machine turned on but
unelectrified
Power cord is not plugged
in place
Check and ensure the power interface
and the power plug is plugged in place
and in good contact.
Fuse burnt-out
Pull out the fuse box from the power
supply interface of the chiller, check the
fuse, replace with spare fuse if
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.
Flow Alarm, connecting the
water outlet and inlet with a
water pipe directly, but still
no water flow
Water level in the water tank
is too low
Check the water level gauge display,
add water until the level shown in the
green area; And check whether the
water circulation pipe leaks.
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.
Water circulation pipes are
blocked or a pipe is bent or
deformed
Check the water circulation pipe.
Ultra-high water
temperatureal alarm
Blocked dust gauze, bad
thermolysis
Disassemble and clean the dust gauze
regularly.
Poor ventilation for air outlet
and inlet
Ensure a smooth ventilation for air outlet
and inlet.
Voltage is extremely low or
unstable
Improve the power supply circuit or use a
voltage regulator.
Improper parameter settings
on thermostat
Reset the controlling parameters or
restore the factory setting.
Switch the power on and off
frequently
Ensure sufficient time for refrigeration
after starting the chiller (at least 5
minutes).
Excessive heat load
Reduce the heat load or use other model
with larger cooling capacity.
Ultra-high room
temperaturealarm
The working ambient
temperature is too high for
the chiller
Improve ventilation and ensure that the
machine is operated below 40°C.
Serious problem of
condensate water
Water temperature is much
lower than ambient
temperature and the
ambient humidity is high
Increase water temperature or insulate
pipes.
Water drains slowly from
drain port during water
changing
Water supply inlet is not
open
Open the water supply inlet
Startup flow alarm
Bubble in the water pipe
Exhaust the air
