CONNECTION TO THE WATER SUPPLY NETWORK
For cold and hot water pipes, you can use steel, plastic or copper pipes, or flexible
connection rated for 0.6 MPa nominal mains water pressure.
When connecting to a copper pipeline, the use of insulating spacers is compulsory.
The package of spacers distributed by HAJDU Hajd úsági Ipar Zrt. includes 2 pieces.
One spacer must be inserted on the hot water pipe of the container immediately,
while the other one on the cold water pipe, between the already installed
assemblies and the copper water pipeline.
If no spacer is used at the connections,
we neither provide guarantee for failures attributable to the corrosion of the
threaded tank pipes, nor assume liability for damages caused by the same.
Subject to the type, you can connect the tank to the water network as shown in
Figure 3 or Figure 4.
IT IS FORBIDDEN AND DANGEROUS TO EXPOSE THE CONTAINER TO PRESSURES
HIGHER THAN THE ALLOWED OPERATING PRESSURE!
1. Closing valve
2. Manometer connection
3. Pressure-reducing valve
(only for mains water pressures
exceeding 0.6 MPa)
4. Combined safety valve
5. Drain (into sewage network)
6. One-way valve

The combined safety valve is included
