7.3 Automatic Filled-Water
When the automatic filled-water valve is installed, the arrowhead orientation
of inlet water must accord with the orientation of the valve.
Automatic filled-water has been adjusted in advance to 1.5ba.
If readjusting the pressure of inlet water, please operate as follows:
•
Open the Screw Cap ( C )
•
If reducing the pressure of water supply, unscrew the pressure to
adjust the screw (B)
•
If increasing the pressure of water supply, screw down the pressure to
adjust the screw (B)
When the system needs to be filled with water at first, rest the handle (A) of
filled-water. Then the handle (A) can return (close) when the system is full of
water.
Automatic filled-water valve needs periodic cleaning. When you must close the tap, unscrew the plug (D), remove
the inside filter net. Reassemble after cleaning.
NOTE: There are two connections for water pressure meters 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.
7.4 Leakage Pressure Valve
The action pressure of the leakage pressure valve is more than 3bar (valve is open), but the pressure cannot be
adjusted.
The valve will open automatically to make sure that the water loop of air-con system is safe when the water pressure
in the backwater side is higher than the set pressure.
