7. Service & Maintenance After the vacuum pumping, connect the air pipe of the refrigerant tank to the liquid filling thimble valve, and fill the refrigerant into the air return pipe. Watch the change of the weight displayed by the electronic scale, and stop filling the refrigerant immediately when receiving the schedule weight.
7. Service & Maintenance 7.2 Maintenance of the subassemblies 7.2.1 Condenser SIC-A series water chillers use the air cooled condenser with ferrule installed openly, in the using time, it hard to avoid any dust and sundries ,which will influence the heat emission effect, so it is necessary to clean the condenser at fixed periods in order to keep its working performance. Use brush, dust catcher or compressed air to clean the wings and copper pipe. Then use the low pressure water to cascade the tray pipe.
