When the automatic filled-water valve is installed, the arrowhead orientation of inlet water must accord
with the orientation of the valve

Automatically filled-water has been adjusted in advance to 1.5bar

If readjusting the pressure of inlet water, please operate as follows:
a.
Open the screw cap (C)

If reducing the pressure of water supply, please screw down the pressure to adjust the screw (B)
c.
If increasing the pressure of water supply, please screw down the pressure to adjust the screw (B)

When the system needs the water filled first, rest the handle (A) of filled water. Then the handle (A) can
return (close) when the system is full of water.

NOTE: There are two connections for the water pressure meter in the central section of automatic filled-water,
where the water pressure meter can be connected directly and display the set pressure. The screw cap ( C ) must be
tweaked after adjusting the filled-water pressure.
7.3 Installation of Leakage Pressure Valve

The action pressure of the leakage pressure valve is more than 3 bar (valve is open) but the pressure cannot
be adjusted.

The valve will open automatically to make sure that the water loop of the air-con system is safe when the
water pressure in the backwater side is higher than the set pressure.
