Water chiller, a necessity for your fish tank or hydroponic system, can effectively provide your fishes, vegetables or fruit with a high-quality, cool and comfortable living environment. NOTE ✪ Please put the chiller in a well ventilated envinronment (at least 15cm/5.9" surrounding space away from other objects) to ensure better heat dissipation. ✪ A certain amount of heat and noise will be generated when the compressor is working, but they will be acceptable and will not affect normal life. ✪ Chiller is leaking? Incorrect pipe installation: check the pipe connection, pay attention to the sealing rings Long-term use may cause the water pipe connection to become loose or larger, and water leakage may occasionally occur. Try to add some vacuum grease to the pipe. ✪ Chiller is not cooling? Please note that only when the water circulation is normal, can the chiller effectively cool the water. If there is no circulation, the pump may be placed too high causing the water flow pressure to be too high or the pump is broken. ✪ The temperature displayed on the screen is inconsistent with the water temperature measured by other thermometers? External factors: such as the lights in the fish tank. The temperature measurement position is wrong. Because the chiller detects the overall water temperature of the fish tank, the other thermometer measures the water temperature at a certain location. The controller is wrong: consider temperature calibration F2 SPECIFICATION ● Water cooling capacity:
