If the connection between the water tank
and the indoor unit must pass through a
wall, make a 70 hole for the passage of the
circulation water pipe.
A PPR pipe is recommended with nominal
external diameter of dn25 and S2.5 as per
standard (thickness of the wall 4.2 mm).
A PPR pipe is recommended with nominal
external diameter of dn20 and S2.5 as per
standard (thickness of the wall 3.4mm).
If other insulated pipes are used, consult the
dimensions given above for the external di-
ameters and thickness of the walls.
At least one stop cock is necessary for the
water outlet pipe.
Installation of the recirculation pipe at the
bottom of the water tank: connect a piece
of the PPR pipe with the run-off outlet of the
floor drain. A stop cock must be installed
at the centre of the run-off pipe and in the
point in which the users can activate it easily.
After connection of all hydraulic piping, first
carry out a leaks control test (see unit de-
bug).
After which, wrap the water pipes, the wa-
ter temperature probe and the cables using
the tape included with the unit.
ATTENTION:
A water tank is recommended on the lower
unit and main on the highest side.
Prepare the materials according to the di-
mensions of the joints stated above.
If the stop cock is installed outside the room,
the use of a PPR pipe is recommended in
order to prevent damage due to freezing.
The hydraulic piping cannot be installed un-
til the water heater unit is fi xed.
Do not allow dust and other materials to en-
ter the piping system during installation of
connection pipes.
After connection of all hydraulic piping, fi rst
carry out a leaks control test. After which,
apply heat insulation of the hydraulic sys-
tem. Pay attention to the valves and the
pipe joints.
Guarantee a suffi cient thickness of the insu-
lating cotton. If necessary, install a heating
device to prevent the pipes from freezing.
The hot water fed from the isolated water
pipe depends on the cock water pressure,
which must always be fed.
During use, the cooling water inlet stop cock
must be kept normally open.
To install the HBi WT/WTS storage tank it is necessary to envision components that are NOT SUPPLIED, whose assembly is recommended
in order to guarantee correct functioning of the hydraulic plant. The recommended components are indicated in the table below;
