<8> Simple troubleshooting
Power cord is not plugged in
place.
Check and ensure the power interface
and the power plug are well plugged.
Replace fuse tube that in the electric
box at the back of chiller
Flow alarm，use a water pipe
connect the water outlet and inlet
but without water flowing.
Low water level in the water
tank.
Check the water level gauge indicator,
pour water until the water meet green
area; and check whether water
circulation pipe leaks.
Flow alarm occurs while running
with applied equipments
, but there is water flowing
without alarm when use a water
pipe directly connected to the
water outlet and inlet.
Water circulation pipes are
blocked or a pipe bending.
Check water circulation pipes.
Upper temperature limit alarm
Anti-dust gauze accumulated
heavy dust leading to poor
heat dissipate.
Remove the anti-dust gauze and clean
it regular.
Poor ventilation for air outlet or
inlet.
Make sure good ventilation
for air outlet and inlet.
Over low or unstable voltage.
To improve the power supply circuit or
use a voltage regulator.
Error parameter setting of
temperature controller.
Resetting parameter or restore to
default setting.
Chiller On/Off frequently
To make sure chiller have enough time
to refrigeration (about 5 minutes
above).
Reduce heat overload, or use larger
refrigeration capacity chiller.
Condensate water heavily.
Water temperature is much
lower than ambient
temperature, high humidity.
To increase water temperature or to
keep warm for pipeline.
Water drains slowly from outfall
when changing water.
Water Supply Inlet not open.
To open water supply inlet.
