※ " A " height + pump pressure = less than the pump head pressure 35m
▶ Cautions in installing the pipe
1. Be sure to install a Air vent or Auto Air vent at the top of the pipes.
2. This product is for the working pressure 3.5kgf/㎠ of cold water supply. Therefore, Install the pipe
in accordance with 3.5kgf/㎠
3. Don't install any valve such as a pressure reducing valve and a check valve at the water supplement
and the drain pipe.
※ Caution against the damage to the boiler due to user's negligence
4. Please install an open type expansion tank or the nitrogen tank(closed type) and a safety valve,
appropriate to the capacity of the boiler to prevent the damage by the thermal expansion pressure.
5. If the boiler is directly connected to the water supply pipe, it may be damaged due to the high pressure
of water supply. Therefore, be sure to install a pressure reducing valve and a check valve.
※ Keep the pressure of the cold water supply within 0.6 - 1.kgf/㎠ to use the hot water sufficiently.
