that there is no leakage and air bubbles.
12.9 Inspection of operation status
Please inspect the items as follows:
1. Temperature of water entering into the heat exchanger
2. Temperature of water returning from the heat exchanger
3. Flow rate at the exit of the heat exchanger
4. Operating current of compressor upon start-up or during stable operation
5. Operating current of fan upon start-up or during stable operation
When the appliance is in cooling process, please use a built-in spindle valve to inspect the saturated
temperature (related to pressure) in the working mode
Referring to the requirements as follows:
1. High pressure side: saturated temperature is about 15-18°C higher than the temperature at the inlet
of condenser.
2. Low pressure side: saturated temperature is about 5-7°C lower than temperature at the outlet of
condenser.
3. When the appliance is the heating process, the water temperature should not be high than 50°C.
