1. Exhaust
Before the cooler starts running, it needs to be exhausted to prevent air or bubbles inside the system from causing poor cooling effect or pipe blockage. The specific operation is to start the water pump and the unit first, open the drain valve to drain the water to the normal water level, then turn off the water pump, start the cooler main motor, allow the cooler to rotate for a period of time, and then open the vent valve to exhaust. The next step can be performed after the exhaust is completed.
2. Load
After the cooler is put into use, a load test is required, that is, the load is gradually increased so that the cooler gradually reaches the rated load state. During the test, it is necessary to observe whether the various performance indicators of the cooler meet the requirements, such as temperature, pressure, water flow, etc.
3. Flushing
After the load test, a full flushing operation is required to ensure that there are no impurities and impurity accumulation inside the cooler. The specific operation is to close the water inlet valve, open the drain valve, drain the cooling water, and then open the water inlet valve and drain valve, and flush with clean water.
4. Debugging
After completing the load test and flushing, a comprehensive debugging operation is required. During the debugging process, attention should be paid to the startup sequence, adjusting the inlet and outlet water temperatures, checking the water level, etc. In particular, for new coolers or when users replace important parts such as fans or water pumps, comprehensive debugging and testing are required to ensure normal operation.
