<8>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
protective tube, replace with spare one if
necessary and check whether the power
supply voltage is stable; Check and ensure
the power interface and the power plug are
in good contact
Flow Alarm(controller displays
E01) use a water pipe directly
connect to the water outlet and
inlet but still without water
flowing
Water level in the storage water tank is
too low
Check the water level gauge display, add
water until the level shown in the green
area; And check whether water circulation
pipe leaks
Flow alarm occurs while
running with other equipment
(controller displays E01), but
there is water flowing and no
alarm when use a water pipe
directly connected to the chiller
water outlet and inlet
Water circulation pipes are blocked or a
pipe bending deformation.
Check water circulation pipe
Ultra-high temperature alarm
(controller displays E04)
Blocked dust gauze, bad thermolysis
Unpick and wash the dust gauze regularly
Poor ventilation for air outlet and inlet
To ensure a smooth ventilationfor air outlet
and inlet
Voltage is extremely low or astable
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 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
Alarm for ultra-high room
temperature
(controller displays E02)
The working ambient temperature is too
high for the chiller
To improve the ventilation to guarantee
that the machine is running under 40℃
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 outfall
during water changing
Injection port is not open
Open the injection port
