How to select the right chiller?
1.Determine the water volume of your aquarium or seafood tank (for recommended water
volumes, see “RECOMMENDED TANK SIZE” for reference).
2.If the ambient air temperature is 89.6°F (32℃) and you expect to cool the water no lower
than 71.6°F (22℃), choose a chiller based on the MAXIMUM water volume.
3.If you expect to cool the water to the temperature between 71.6°F(22℃) - 60.8°F(16℃),
choose a chiller based on the MINIMUM water volume.
4.If you expect to cool the water no higher than 60.8°F(16℃), you may consider a higher
power chiller, or reduce the water volume.
5.Please note that other factors such as room ventilation, aquarium/tank structure, water
flow rate, lighting system, surrounding heat sources etc., will also affect water chilling
efficiency.
The below performance curves are for the user’s reference in choosing the right chiller.

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
The installation of the chiller should comply with the safety precautions and warnings.
The unit must be used with a circulating system and a filtering system.
Installation method:
Aquarium/tank -- filtering system/filter -- water pump -- inlet of chiller -- outlet of chiller --
aquarium/tank.

- 8 -
1.The product has two fittings on one side for tubing connections, with the bottom one for
inlet and the top for outlet. Connections of the aquarium/tank and water pump can be made
with either soft or hard tubing (hard tubing is better for high water flow). For the tubing
diameter please refer to the diameter of the connector supplied. After tubing is connected,
please make sure there are no kinks, tangles or items on tubing as this may block the water
flow.
2.Position the outlet tube going to the aquarium/tank slightly above the water lever and
secure in place. Position the inlet tube 5cm~10cm above the bottom of aquarium/ tank.
Make sure that the inlet and outlet are positioned at opposite sides of the aquarium/tank.
When applied to multi-layer of seafood tank, the outlet tube should be positioned above the
top layer, allowing the water to trickle down. At the bottom layer, the water pump firstly
pumps the water into filter then into the chiller unit.
3.The chiller unit must be installed in a condition with good ventilation. Keep the clearance
of at least 30cm for the back (air inlet) and two sides and at least 60cm for the front (air
outlet). See the Fig.1. More clearance should be provided when the machine works in high
power. Otherwise, the cooling efficiency will be reduced or even cause malfunction.
Fig. 1
Attention: Check the chiller inlet and outlet carefully, DO NOT MISCONNECT.
Ⅴ. HOW TO USE

- 9 -
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 fittings and joints are correctly and tightly fitted and there are no leaks.
(3)The tubing and connections are all clean, no kinks, tangles or clogs.
(4)Keep sufficient clearance between the chiller and its surrounding objects for heat
dissipation and convenient maintenance, with at least 30cm clearance around back (air
inlet) and sides and 60cm in front (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 4 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.
How it works?
The machine is operated by the microcomputer with functions such as temperature control,
delayed protection, over current protection, and blackout memory.
Once you set up a temperature (required water temperature), the microcomputer controller
will choose cooling mode according to the difference between the actual water temperature
and the setup temperature, and automatically turn on the machine.
When actual water temp ≥ setup temp + tolerance temp, cooling mode will be on. When the
actual water temp reaches the setup temp, machine will be off. The water temp stays at
pre-set temperature with a tolerance of 2℉. In the event of a power outage, the chiller will
automatically restart when power comes back on.
Adjust temperature
1.Press “SET” to enter setting, the control panel displays pre-set temperature.
2.Press ▲ to turn up pre-set temperature, and press ▼ to turn down pre-set temperature.
3.Stop pressing any key for 10 seconds, digital control panel will exit to temperature display,
and the setting takes effect. The green indicator blinks in “delayed start” state, after a 3
minutes’ delay, the chiller starts chilling automatically.

Calibrate the temperature
If the displayed water temp is different from the actual water temp, please calibrate the
digital display as below steps:
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.
3.After your adjusting operation has stopped for 10 seconds, the control panel will exit to
show the adjusted temperature.
Check indicator light
1.Power (Yellow): power supply is connected and the chiller is in stand-by state.
2.Cooling (Green): Blinks in “delayed start” state, steady on in “cooling" mode.
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.
