<7> 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
(panel red light is
on)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.
Water circulation pipes are blocked or a
pipe bending deformation.
Check water circulation pipe
Ultra-high
temperature alarm
Blocked dust gauze, bad thermolysis
Unpick and wash the dust gauze
regularly
Poor ventilation for air outlet and inlet
To ensure a smooth ventilation
for 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 minuets)
Excessive heat load
Reduce the heat load or use
other model with larger cooling
capacity
Alarm for ultra-high
room temperature
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, with 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
