In order to drain condensate water continuously, please install the appliance on a horizontal floor. If this is not
possible, please ensure that the drain vent is at the lowest possible place. It is recommended to place the
appliance in a way that the inclination angle between the appliance and a vertical line is not more than 2°.
7.3. 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.
