<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 E6) 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 E6), 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
（

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 minutes)
Excessive heat load
Reduce the heat load or use other
model with larger cooling capacity
Alarm for ultra-high room
temperature(Temperature
controller panel display E1)
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
