Page 8: Change Drier Filter, Evacuate Drier Filter And Reset Service Interval Time
TEKTINO RCC-9A maintenance manual Change drier filter, evacuate drier filter and reset service interval time When a drier filter is replaced, the moisture may enter into equipment pipeline and affects quality of refrigerant in the equipment tank. Thus it is mandatory to evacuate the drier filter each time a drier filter is replaced. -
Page 9: Leak Test
RCC-9A maintenance manual V2.0 TEKTINO LEAK TEST Under the following situations, it is possible that the machine has leakage in pipeline connections, thus need to make leakage test: 1. The refrigerant volume in equipment tank reduces, without operations; 2. Compressor and Solenoids work well, while recovery works too slow or can not work normally;... - Page 10 TEKTINO RCC-9A maintenance manual d) Write down the pressure of each gauge, shut down the equipment. After 4 hours, check pressure of the three gauges. If any gauge shows more than 0.1 BAR pressure down, means the pipeline related to that pressure gauge has leakage (refer to pipeline diagram of this manual).
