08. Appendix
8.2 Appendix 2 – Installation of the Automatic Fill-water Valve
8.3 Appendix 3 – Installation of the Leakage Pressure Valve
8.4 Appendix 4 – Assistant Heat Sources
1. When installing the automatic fill-water valve, the arrowhead orientation
of inlet water must be in accordance with the orientation of the valve;
2. Automatic fill-water must be adjusted in advance to 1.5 bar;
3. If the pressure of inlet water needs to be re-adjusted, please follow the
following procedure:
• Open the screw cap (C).
• If the pressure of the water supply needs to be reduced,
loosen the screw (B).
• If the pressure of the water supply needs to be increased,
tighten the screw (B).
• If the system needs to be filled with water, wrest the handle (A) before
filling. Then return and close the handle once the system is full of water.
• The automatic fill-water valve needs to be cleaned regularly. Before
cleaning, close the tap, unscrew the plug (D), and remove the inside filter
net. Please assemble them again after cleaning
NOTICE: There are two available connections for the pressure meter
at the center of the automatic fill-water valve. The screw cap (C) must
be tweaked after adjusting the fill-water pressure.
1. The action pressure of leakage pressure valve is more than 3bars and
the pressure cannot be adjusted.
2. The valve will open automatically to make sure that the water loop
of the airconditioning system is safe when the water pressure in the
backwater side is higher than the set pressure.
The unit allows for the connection of an assistant heat source, which can be a gas-fired boiler or an
electronic boiler. The possible schematic diagrams for their connection are as follows:
