NOTES:
1.Refrigerating effect will be impacted by ambient temperature, water circulation flow rate,
installation position, lighting system, surrounding heat sources, room ventilation,
aquarium/reservoir structure, etc. To get the best use of this machine, please strictly follow
this instruction manual.
2.Recommended water volume is closely related to the ambient temperature and the
required water temperature. When ambient temperature is high (and a low water
temperature is required) the water volume should be REDUCED to achieve best
performance.

Ⅳ. INSTALLATION
TIPS！Please check the accessories before installation.
Installation method:
1.Check the Accessories Box, inside of which there are 2 PVC hoses, 1 water pump, 1
hose clamp, and 1 suction cup. See the Fig.1. Take out the 2 hoses firstly.
Fig. 1
2.Go on Check the Accessories Bag. See the Fig.2. Assemble the water inlet and outlet.
See the Fig.3.
Fig. 2
Fig. 3
3.Fix water inlet and outlet on the chiller. See the Fig.4 and connect to the PVC flexible
hoses. See the Fig.5.
Fig. 4
Fig. 5

- 10 -
4.Pick the hose 1 ( the hose with one end connected to the chiller inlet), see the Fig. 5, then
connect the other end to the water pump outlet, fasten the hose clamp tight (see the Fig. 6)
Pick the hose 2 (the hose with one end connected to the chiller outlet), then insert the other
end through the elastic ring of the suction cup, and fix it at proper position inside the
aquarium wall (see the Fig.6.)
Note: for the water pump installation, please refer to the Water Pump Instruction Manual.
Attention: Check the chiller inlet and outlet carefully, DO NOT MISCONNECT.
Fig. 5
Ⅴ. HOW TO USE
Before using the machine, please check:
(1)Power cord is securely plugged into a grounded, correctly rated outlet. Make sure the
power voltage and frequency are in accordance with the data specified on the nameplate
or in the instruction manual.
(2)The water inlet, outlet and hose are connected correctly and firmly, make sure there are

- 11 -
no leaks or clogs.
(3)Keep sufficient clearance between the chiller and its surrounding objects for heat
dissipation and convenient maintenance, with at least 30cm clearance around front (air
inlet) and sides and 60cm in back (air outlet). If the chiller is to be put in an aquarium
cabinet, the cabinet should have enough grilles for air circulation, or to be equipped with an
extra small exhaust fan.
If the 3 items above are OK, you may begin using your water chiller:
(1)Turn on water pump, making sure the Circulating Cooling Water System can run
normally without any blockage or leak.
(2)Turn on the chiller and use the Control Panel to set desired water temperature.
Adjust temperature
1.Plug the chiller into a socket of rated voltage and frequency, turn it on. The power
indicator light is on and the LCD shows the current water temperature.
Fig.1.
2.Press “SET” to enter the setting. Press ▲ to turn up pre-set temperature, and press ▼ to
turn down pre-set temperature. The starting temperature difference is 2℉，for example, the
chiller needs to be set at least 2℉lower than the actual water temperature to get it started.
The chiller needs to set at least 2℉lower
than the actual water temperature to cool.
The chiller needs to set at least 2℉higher
than the actual water temperature to heat.
Fig.2.
Fig.3.

- 12 -
3.After setting the temperature, the LCD shows the current water temperature, and the
chiller will select cool or heat mode automatically after comparing the set temperature and
actual water temperature. If in cool mode, the green indicator blinks in “delayed start” state,
after a 3 minutes’ delay, the chiller starts chilling, and the green indicator becomes solid. If
in heat mode, the heater works without delay and the red indicator turns on (Note: heater
not included, it requires the user to insert a heater with a two-pin flat plug).
Fig.4.
4.When the chiller works in cool mode, the green indicator turns on. When the water
temperature drops to the pre-set temperature, the chiller stops working. If the water
temperature rises to meet the starting condition (temperature difference is 2℉), the chiller
enters a 3-minute delay and then starts working automatically. By repeating in this way, the
chiller keeps the water temperature stay between pre-set temperature and the temperature
+ 2℉. See the Fig. 5.
5.When the chiller works in heat mode, the red indicator turns on. When the water
temperature rises to the pre-set temperature, the heater stops working. If the water
temperature drops to meet the starting condition (temperature difference is 2℉), the heater
works again. By repeating in this way, the chiller keeps the water temperature stay
between pre-set temperature and the temperature - 2℉. See the Fig. 6.
Fig.5.

Ⅵ. MAINTENANCE
1.Regular maintenance is needed each year. Please power off and unplug before
maintaining.
2.Please DO NOT use chemicals such as gasoline, benzene and diluent to wipe the chiller.
3.Control panel and motor must be kept dry. If water or any liquid is found on the chiller,
please turn off the power immediately and wipe it off with cloth before restarting.
4.DO NOT operate the chiller if it has a damaged cord or plug, or it is malfunctioning or has
been dropped or damaged in any manner.
5.DO NOT attempt to service this unit yourself as opening or removing covers may expose
you to dangers or other hazards. Refer servicing to qualified service personnel for service
or replacing all electrical parts.
6.If the chiller is not in use for a long time, please unplug the power cord, fully discharge the
residual water in the tubes, clean the inlet/outlet and hoses and dry them thoroughly. Put
the chiller away at a safe dry place.
Ⅶ. CLEANING
Step1: Please unplug (important!). See the Fig. 1.

- 14 -
Fig.1
Step2: Please open the front cover (see the Fig. 2), and then take the air filter out (see the
Fig. 3).
Fig.2
Fig.3
Step3: To prevent dust accumulation, please clean the air filter in water or with a vacuum
cleaner regularly. See the Fig. 4
Fig.4
Note: For optimal refrigerating performance, circulating and filter system, and the air filter
should be cleaned at least once every month including hoses, fittings, filter media, titanium
tube inside the machine and others, as the dirt accumulation and or clogs would weaken
the refrigerating capacity.

The displayed
water temp is
different from the
actual water temp
There is tolerance
between the LCD
displayed temp and the
actual water temp.
To calibrate water temperature:
1. Press and hold “SET” for 10 seconds to
enter Temp Error Adjustment Function,
digital display will show “CA”.
2. Press "▲"(turn up) or "▼" (turn down)
until the displayed figure equals to the
tolerance intended to eliminate (tolerance
CA = actual water temp - displayed water
temp), adjusting range is +4 to -4.
