Pipeline connection

It is forbidden to connect the appliance with a hose pipe. Galvanized steel
pipe, plastic pipe and red copper pipe can equally be used as cold water pipe or hot
water pipe. In case of connecting red copper pipes to the water pipeline system, the
use of insulating intermediate pieces is compulsory.
The package of intermediate pieces distributed by HAJDU Zrt. are sold in
outlay of 2 items in contracted shops of HAJDU Zrt. and in the general commerce.
One of the intermediate pieces should be mounted directly to the hot water pipe of
the tank, while the other should be mounted between the fittings already mounted
and the red copper water pipeline system.
In case of connection without intermediate pieces, the guarantee on the appliance
will be invalidated.
IT IS AT THE RISK OF DEATH AND THEREFORE IT IS FORBIDDEN TO PUT THE
WATER TANK AND THE HEAT EXCHANGERS UNDER A PRESSURE LARGER
THAN THE PERMITTED OPERATION PRESSURE (0.7 MPa) !
During connection to the water pipeline system, it is compulsory to keep the
building order of the fittings according Figure 7.3. -1., as proper operation of the
appliance highly depends on that.
