①
Please ask our dealer or professional
staff
to
install
the
chiller
The person who installs
the
chiller
must be certified by government
recognized
licensor, if the chiller was not installed properly, water leakage, fire, and wound
,
electric
shock
may
occur
.
②
Take proper measures to prevent suffocation
caused
by
refrigerant
leakage
If the machine is installed indoor, ventilation well could avoid of suffocation
hazard
caused
by
gas
leakage
.
③
Make sure the machine is properly grounded.
Electric shock may occur if the machine is installed without grounded
.
④
Don
'
t stretch anything into the equipment.
The high speed fan will be damaged by foreign material.
⑤
In case of
abnormal
running
appear
,
cut
off
the
power
,
contact
our
local
dealer
for
instructions
.
Fire hazard, electric shock etc. might occur if keep running the machine under
abnormal conditions.
⑥
Don
'
t operate the machine with wet hands.
Electric shock may occur.
⑦
Don
'
t repair the chiller by yourself
In safety sake, please ask our dealer or a professional staff to repair it.
⑧
Don
'
t install the chiller in a flammable
and
explosive
place
⑨
Neutral liquid and liquid whose gravity and heat transmission are similar with
water are required, in order to protect the water pump, water with solid particles
are not allowed
.
⑩
when replace the liquid please note the pump can
'
t be run without water.
⑾
In cold areas, proper anti-freezing measures should be done.

Solution for no error codes display
①
Please check whether the condenser
radiator
and
air
filter
is
dirty
②
Whether the temp. of the installation site is too high and ventilation condition is bad
③
Slightly refrigerant leakage(E3 error has been reported yet)
④
Whether the chiller has exceeded its designed lifetime, replace a new compressor
might be a solution
Ⅱ.
Unstable
temperature
:
If the chiller is keeping chilling or the water temperature is keep rising, please check the
voltage of power supply (Normal voltage range: 197~242V), since over-low voltage will
make the cooling magnetic valve and bypass magnetic valve
fail
to
alternate
.
Ⅲ.
No
water
flow
or
low
water
flow
:
Please check
below
:
Whether there
'
s air inside the water pump, check
whether
the
filter
under
the
water
tank
is
blocked
,
whether
the
pump
capacitor
is
working
and
the
pump
relay
is
closed
.
Ⅰ.
Insufficiency
cooling
:
Required periodic maintenance
5.1 Condenser, vent hole, air filter
Condenser, vent hole, air filter should keep clean and periodically inspect in
order to optimize the performance of cooling
5.2 Pure water filter
Please rinse and replace the filter periodically.
5.3 Liquid level
Please check the water level periodically, the water level should be above the
coil, water supplement is necessary if the water level is lower than the coil
;
please
replace
the
water
frequently
based
on
the
actual
water
condition
.
If
the water flow is not normal, please press the red button on the water filter to
discharge the air inside the water circuit. Please check
whether
the
back
water
circuit
is
leakage
and
the
water
level
is
lower
,
when
there
'
re bubbles in the
soft tube and back water inlet.
5.4 Clean the air filter periodically
The air filter could be removed easily from both sides, use gentle detergent to
remove the dust, clean the filter with clean water, and fix
the
filter
back
after
it
'
s dry.
