Pipeline Connection - LEGALLAIS HB300 Manuel De Mise En Service, D'opération Et D'entretien

The selected location must be ready to house a discharge opening for
condensate water connected to the upper part of the appliance with a flexible
circuit.
Please ensure that
systems to which the appliance will be connected fully comply with all relevant
regulations.
The selected location has to possess (or to be able to house) a single phase
230 V ~ 50 Hz external switch.
According to the definitions of relevant regulations, the selected location has
to comply with IP protection class (protection against liquid penetration).
Do not expose the appliance to sunlight, not even through any window.
The appliance must not be exposed to effects of especially aggressive
materials, i.e. acidic gases, environment saturated by dust or gas.
The appliance must not be mounted directly to phone line without overvoltage
protection.
The appliance must be placed and operated as close to the usage points as
possible, in order to limit the diffusion of heat along the pipeline.
Adequate electric power system, water pipeline and sewage system should
be ensured on the location of the operation. (floor drain).
In order to reduce heat loss due to hot water pipe, please install the appliance
close to hot water usage locations, if possible. In case of larger distances, it is
rational to equip the hot water pipe with heat insulation.
Unused connection branches of the hot water tank must be closed and
equipped with heat insulation. .

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.
