INSTALLATION MEASURES
The water tank must be installed and kept
at a horizontal distance of 5 m and verti-
cal distance of 3 m from the indoor unit. It
can be installed in the room.
The upright water tank must be installed
vertically with the base on the ground,
never suspended.
The place of installation must be suffi -
ciently stable and the tank must be fi xed
to the wall using bolts in order to prevent
vibrations, as shown in the following fi gure.
The minimum distance between the wa-
ter tank and heat source surfaces must be
500 mm.
A water pipe must be present along with
a joint for hot water and a run-off in the
fl oor, near to the tank in order to favour
fi ling with water, supply of hot water and
emptying of the water tank.
To make the hydraulic connections use
PPR pipes and wrap them with tape for
insulation
!
ATTENTION:
For safe use of the water, the inlet/outlet
of the water of the relative tank must be
connected with the PPR pipe of a certain
length, L ≥70×R2 cm R is the internal radius
of the pipe.
Moreover, heat insulation must be per-
formed and metal pipes must not be
used.
Before use, the water tank must be full be-
