CW-5000/5200 Series
<7> Simple troubleshooting
Failure
Machine turned on
but unelectrified
Flow Alarm
(panel red light is
on)use a water pipe
directly connect to
the water outlet and
inlet but still without
water flowing
Ultra-high
temperature alarm
Alarm for ultra-high
room temperature
Serious problem of
condensate water
Water drains slowly
from outfall during
water changing
Failure Cause
Power cord is not plugged in place
Fuse burnt-out
Water level in the storage 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 astable
Improper parameter settings on
thermostat
Switch the power frequently
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
Approach
Check and ensure the power
interface and the power plug is
plugged in place and in good
contact.
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.
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
Unpick and wash the dust gauze
regularly
To ensure a smooth 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 minuets)
Reduce the heat load or use
other model with larger cooling
capacity
To improve the ventilation to
guarantee that the machine is
running under 40ć.
Increase water temperature or
to preserve heat for pipeline
Open the injection port
