VIII. Simple Troubleshooting
Failure
Machine turned on but
unelectrified
Flow Alarm. Use a water pipe
to directly connect to the
water outlet and inlet but still
without water flowing
Flow alarm occurs while
chiller is connecting toother
equipment, but there is water
flowing and no alarm when a
water pipe is directly
connected to the chiller
water outlet and inlet.
Ultrahigh water temperature
alarm
Ultrahigh room temperature
alarm
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 bending
deformation.
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 room temperature is
too high for the chiller
Water temperature is much
lower than ambient
temperature, high humidity
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.
Open the electric box cover, check the
fuse and replace with a spare one if
necessary. Check whether the power
supply voltage is stable; Check and
ensure the power interface and the
power plug are in good contact.
Check the water level gauge display,
add water until the level shows in the
green area; And check whether water
circulation pipe leaks.
Check water circulation pipe
Disassemble and clean the dust gauze
regularly
To ensure a good ventilation
for air outlet and inlet
To improve the power supply circuit or
use a voltage regulator
To reset controlling parameters or
restore factory settings
To ensure there is sufficient time
for refrigeration
(more than 5 minutes)
Reduce the heat load or use other
model with larger cooling capacity
To improve the ventilation to
guarantee that the machine is running
below 40℃ room temperature.
Increase water temperature or
to preserve heat for pipeline
Open the water supply inlet
Exhaust the air
