1. Maintain a clean surface of the filter screen of the Dongguan water chiller, circulate air around the filter screen, and regularly clean the filter screen. Generally, use compressed air to purge the filter screen once every 30 days.
2. Reduce the occurrence of "sweating" in the mold.
3. Before stopping the plastic machine, first turn off the cold water brake of the accessory mold, or turn off the Dongguan water cooler to increase the water temperature in the mold cavity, so that the mold will not produce rust deposits.
4. If the Dongguan water chiller has been in use for more than six months, or the high and low pressure engines frequently fail, or the cooling capacity decreases, please arrange for staff to clean the radiator (if the Dongguan water chiller is equipped with a pressure gauge, and if the pressure of the high pressure gauge is higher than 300 PSI, if it exceeds, the surface of the radiator should be cleaned and kept clean to improve the effect of the radiator). If the water chiller still fails after cleaning several times according to the above instructions, please arrange for staff to repair it.
5. Dongguan water chiller has been out of service for a period of time, and due to the solidification of water pollutants, the pump blades may be solidified by the pollutants. When restarting, the pump rotor must be loosened first to avoid the pump blades not rotating, which may cause the fuse to burn out. (Applicable to chillers below 5 horsepower).
