Installation The installation of the chiller must comply with the safety precautions and warnings. The unit must be used with a circulating system and a filtering system. As outlined below: aquarium or reservoir -- filtering system or filter -- water pump -- inlet of chiller/warmer --outlet of chiller/warmer--aquarium/reservoir.
Installation The product has two terminals on one end, with the bottom one for inlet and the top for outlet. Connection of the aquarium/reservoir and water pump can be made with either soft or hard tubing (for high water flow, hard tubing is better). For the tubing diameter please refer to the diameter of the connector supplied. When using soft tubing, make sure there is no bending, entanglement or pressure applied to the tube, as this may block the water flow.
Operation (1)Temp setting: a. Press “SET” to enter setting feature, digital control switch, display pre-set temperature; b. Press c. Stop pressing any key for 6 seconds ,digital control panel will exit to temperature display, and the setting takes effect. The machine will start refrigerating automatically. (2) Calibrating of the temperature If the displayed water temp is different from the actual water temp, calibrating the digital display as below: a.
Maintenance Precautions 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. Do not tilt or lay the machine on its back. If the machine has been tilted or laid, please position it upright and wait 30 minutes before restart.
