Water system piping

In case of installing the unit at a place where outside temperature below freezing point,
insulation must be provided for all hydraulic components.

Water inlet or outlet pipes: The specification of the water inlet or outlet thread is RC3/4",
which is external thread. Pipes should be heat-insulated well.

Installation of the one way valve: The specification of the valve thread in accessories is
RC3/4". It is used to prevent water from flowing backwards.

The drainage pipe should be insulated to prevent water inside pipe from freezing in cold
weather.

Do not dismantle the PT Valve, and do not block off the drainage pipe.

After water system piping connection, turn on the inlet and outlet valve to effuse the tank.
When water flow smoothly out from outlet pipe, the tank is full, turn off all valves to check
the pipeline leakage.

If the inlet water pressure is less than 0.15MPa (1,5atm), a pump should be installed at
the water inlet. If the water supply hydraulic is higher than 0.65MPa (6,5atm), a reducing
valve should be installed at the water inlet pipe.

Condensate may be leaked from unit if drainage pipe is blocked, so a drainage pan should
be installed.
