Viii.simple Troubleshooting - S&A CW-5000 Installation & Operation Instructions

VIII. Simple Troubleshooting
Failure
Machine turned on
but unelectrified
Flow Alarm, connecting
the wateroutlet and inlet
with a water pipe directly,
but still no water flow
When connecting the
chiller with the machine
to be cooled, flow alarm is
triggered; but when
connecting the water
outlet and inlet with a
water pipe directly, water
flows and the flow alarm
is not triggered.
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 blown
Water level in the storage
water tank is too low
Water circulation pipes
are blocked or a pipe is
bent or deformed
Blocked dust gauze, bad
thermolysis
Poor ventilation for air
outlet and inlet
Voltage is extremely low
or unstable
Improper parameter
settings on thermostat
Switch the power on and
off frequently
Excessive heat load
The working ambient
temperature is too high for
the chiller
Water temperature is
much lower than ambient
temperature and the
ambient humidity is high
Water supply inlet is not
open

Approach
Check and ensure the power interface and the
power plug isplugged 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 the water circulation pipe leaks.
Check the water circulation pipe.
Disassemble and clean the dust gauze regularly.
Ensure a smooth ventilation for air outlet and
inlet.
Improve the power supply circuit or use a voltage
regulator.
Reset the controlling parameters or restore the
factory setting.
Ensure the time for the refrigeration process after
starting the chiller (at least 5 minutes).
Reduce the heat load or use other model with
larger cooling capacity.
Improve ventilation and ensure that the machine
is operated below 40°C.
Increase water temperature or insulate pipes.
Open the water supply inlet
