1. Water pipe system diagram
•
The water pressure resistance of the water pipe system of this product is 1.98MPa
•
When the water pipe passes indoors, make sure to execute heat insulation on the pipe so that water drops
do not form on the outer side of the water pipe.
•
The size of the drain pipe must be equal to or larger than the diameter of the connecting product.
– Always install a trap so that the drained water does not back flush.
•
Always install a strainer (50Mesh or above) at the entrance of the water pipe. (When sand, trash, rusted
pieces get mixed into the water supply, it can cause problems to the product due to blocking)
– If On/Off valve is applied, by interlocking with outside unit, it can save the energy consumption of pump
by blocking the water supply to the outside unit not operating.
Select appropriate valve and install on site if necessary.
•
Install a pressure gauge and temperature gauge at the inlet and outlet of the water pipe.
•
Flexible joints must be installed not to cause any leakage from the vibration of pipes.
•
Install a service port to clean the heat exchanger at the each end of the water inlet and outlet.
•
For the components of the water pipe system, always use components above the designed water pressure.
•
For protecting the heat exchanger, it should be installed the flow switch.
