Simple troubleshooting
FAILURE
FAILURE CAUSE
APPROACH
Check and ensure the power
interface and the
power plug is
plugged in place and in good contact.
Power cord is not plugged in place
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
Check the water level gauge display, add water
until the level shown in the green area; And check
whether water circulation pipe leaks.
Check water circulation pipe
Flow Alarm (panel red light is
on)use a water pipe directly
connect to the water outlet and
inlet but still without water flowing
Machine turned on but
unelectrified
Ultra-high
temperature alarm
Alarm for ultra-high room temperature
Serious problem of condensate water
Water drains slowly from outfall
during water changing
Switch the power frequently
Blocked dust gauze, bad thermolysis
Poor ventilation for air outlet and inlet
Voltage is extremely low or astable
Improper parameter settings on thermostat
Excessive heat load
The working ambient temperature is too
high for the chiller
Water temperature is much lower than
ambient temperature, with high humidity
Injection port is not open
Open the injection port
Increase water temperature or
to preserve heat
for pipeline
To improve the ventilation to guarantee that the
machine is running under 40
℃.
Reduce the heat load or use
other model with
larger cooling
capacity
To ensure there is sufficient time
for refrigeration
(more than 5 minuets)
To reset controlling parameters
or restore factory settings
To improve the power supply
circuit or use a voltage regulator
To ensure a smooth ventilation for air outlet and inlet
To ensure a smooth ventilation for air outlet and inlet
Water level in the storage
water tank is too low
Water circulation pipes are blocked
or apipe bending deformation.
