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
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.
Flow Alarm, Use a water pipe
to directly connect to the
water outlet and inlet but still
without water flowing
Water level in the water
tank is too low
Check the water level gauge display,
add water until the level shows in the
green area; And check whether water
circulation pipe leaks.
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.
Water circulation pipes are
blocked or a pipe bending
deformation.
Check water circulation pipe
Ultrahigh water temperature
alarm(temperature controller
displays E2)
Blocked dust gauze, bad
thermolysis
Disassemble and clean the dust gauze
regularly
Poor ventilation for air
outlet and inlet
To ensure a good ventilation
for air outlet and inlet
Voltage is extremely low or
unstable
To improve the power supply circuit or
use a voltage regulator
Improper parameter
settings on thermostat
To reset controlling parameters or
restore factory settings
Switch the power on and
off frequently
To ensure there is sufficient time
for refrigeration
(more than 5 minutes)
Excessive heat load
Reduce the heat load or use other
model with larger cooling capacity
Ultrahigh room temperature
alarm(temperature controller
displays E1)
The room
temperature is too high for
the chiller
To improve the ventilation to
guarantee that the machine is running
below 40
℃
room temperature.
Serious problem of
condensate water
Water temperature is much
lower than ambient
temperature, high humidity
Increase water temperature or
to preserve heat for pipeline
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
