Water supply system test run
Judging whether there is any

Execute the product test run
64 Outside Unit
Design the system including cooling tower, boiler, pump etc.
- Check the equipment capacity (Water volume, temperature control range).
Install the water pipe
Connect the water pipe to the inlet/outlet of the product so that the water
can be supplied to the product.
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

- 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.
Execute the test of water supply system without operating the product.
- Check whether outside unit inlet/outlet flow rate complies to the product
specification.
Standard Water volume is 80LPM based on 8HP and 150LPM based on
16HP.
- Check the water supply temperature. whether is OK
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 dis-
charged with the water supply blocked, discharge the refrigerant after
draining out around the outside unit.
