10. Installation of water pipe

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 corrosion.)

- The ON/OFF valve blocks the water supply to the outdoor unit that is not operating to save the pump power. Select

appropriate on whether to install this or not for the site.

• Install a pressure 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.

2) Water pipe connection

• The water pipe should be the same size of the connection on the product or more.

• Be sure to install the insulation material in the water pipe inlet/outlet to prevent water drop, freeze and to save energy.

(Use the above 20mm thickness Pe insulation material.)

• Tightly connect the socket to the water pipe refer to below table for recommended specification.

(Too much torque may cause the damage of the facility.)
