Execute the product
test run
Before executing the test run for the product, you must first test the heat source water system.
The test run for the product must be executed after checking the flow rate and temperature of the heat source water supplied.
// Equipment design //
Design the system including cooling tower, boiler, pump etc.
- Check the equipment capacity (Water volume, temperature control range).
// Water pipe system installation //
Install the water pipe
// Water supply pipe and product connection //
Connect the water pipe to the inlet/outlet of the product so that the water can be supplied to the product.
// Water supply system test run //
Execute water supply system test run
- The product does not operate but the pump and water supply equipment will operate to flow the Heat source water to the
heat exchanger on the product side.
- Flow the water to all water piping system to clean any alien particles inside the pipes and execute an air purge to remove
an air within the pipes to make the water supply smoother.
- Clean all the strainers of water pipe including around outside units
// Judging whether there is any problem with the water supply //
Execute the test of water supply system without operating the product.
- Check whether outside unit inlet/outlet flow rate complies to the product specification.
- Check the water supply temperature. whether is OK.
// Execute the product test run //
After checking the normal condition of the water supply, execute the test run of the product.
To prevent the freezing of the heat exchanger when the refrigerant is discharged with the water supply blocked, discharge
the refrigerant after draining out around the outside unit.
