Installation：

Required Tools (not included): Hose clamps and water source.

1. Place the chiller in a well ventilated level surface.
2. Attach the barbed compression fitting to the chiller intake and output.
   Attach flexible tubing to the intake barb on the chiller using a hose clamp to ensure tightness.
3. Connect to water supply or water pump to the unit. Water flow should be a min. of 100 GPH and not to exceed 400 GPH. It is recommended to pre-filter the water first.
   Attach a piece of flexible tubing to the output barb of the chiller using a hose clamp.
   Verify that the water returning from the chiller is not in close proximity to the intake water source.
4. Secure the return line.
5. Verify that there are not any kinks in the tubing supplying water to the chiller or in the output tube returning water to the aquarium or sump.
6. Turn on water pump or water supply.
7. Check all connections to verify that there are not any leaks.

SETTING THE THERMOSTAT:

1. Plug the chiller into a G.F.C.I. outlet.
2. Switch the unit ON.
3. The LED screen now will read the temperature of the current aquarium water.
   Press the SET button. The LED screen will now flash and the green led light will be lit.
   Adjust the temperature using the UP/DOWN buttons. Once the LED screen reads the correct temperature, Press the SET button again. The green LED light will then go out.
4. There is a 2-3 minute delay prior to the chiller turning on. When the chiller is ON, the green LED light will be lit.

Note:

• If installing on a preexisting aquarium, lower the temperature by 1-2 degrees per day.
• If the unit is turned off, it will take a minimum of 3 min. to come back on. It will take up to 5 min. for the computer/thermostat to adjust to the aquarium temperature and the set temperature prior to turning on.

Maintenance：

1. It is recommended to clean the radiator once a month. To do this, gently vacuum the radiator to remove all dust and debris.
2. Do not hose down or use water to clean the radiator or other external components.
   Once a month, flush the internal heat exchanger with clean fresh water. Do not use any soap or detergents.
3. Do not submerge in water. The chiller must be completely free of all moisture.
4. Once a month, clean the pre-filter of the pump supplying water to the chiller.

Note: If you have any questions or concerns about working on the chiller, always consult a certified electrician first.
