5. PIPELINE CONNECTION
Any steel pipe, plastic pipe and red copper pipe or flexible pipe connection
adequate to a water pressure rated as 0.6 MPa can be used as hot or cold
water pipes.
In case of connecting red copper pipes to the pipeline system, the use of
insulating intermediate pieces is compulsory.
One of the intermediate pieces has to be mounted directly to the hot water
pipe of the water tank, while another intermediate piece has to be mounted
between the already fixed fittings and the red copper pipeline system. In case
of connection without intermediate pieces, our Company undertakes no
guarantee for defects due to corrosion of internally threaded pipe ends of the
water tank, neither any liability resulting from or related to such events. The
middle piece not accessory. Can be ordered: 3/4" Article Nr. 1252122513
The water tank should be connected to the pipeline system according to
Figure2.
IT IS AT THE RISK OF DEATH AND THEREFORE IT IS FORBIDDEN TO PUT THE
WATER TANK UNDER A PRESSURE LARGER THAN THE PERMITTED OPERATION
PRESSURE!
5.1. The combined safety valve is an accessory of the water tank.
Its
connection to the hot water tank and to the pipeline system: Rp3/4 internally
threaded.
The valve has to be mounted DIRECTLY in front of the water tank into the cold
water pipe, respecting the flow direction marked by an arrow. Before
mounting the valve, the cold water pipeline has to be flushed thoroughly, in
order to avoid any damage caused by any possible pollution.
The outlet tube has to be placed vertically downwards and the blow-off
button has to be accessible. In the order of water flow, it contains the one-
way valve, the security valve and the outlet tube that has to be left open
toward the air space.
