I)
Make the electrical connections between the electrical panel
and the main power supply and between the electrical panel and
the terminal block located on the right side of the outdoor unit
following the instructions in table 1.
Arrange a dedicated power line that starts directly from the meter
to bring the main power supply to the electrical panel located
inside the cover of the indoor unit.
This line must be equipped with a special magneto-thermal
protection placed upstream and must be of such a section as to
avoid a voltage drop higher than 2.5 V.
G)
Proceed with connecting the flow and return of the heating
system using the 3/4” fittings
ATTENTION! the circulator mounted on the machine is
able to provide the nominal water flow rate with the head
indicated in the technical data table. Check that the pressure
drops are not higher than the available available head.
However, it is recommended to comply with the following
requirements:
- the diameter of the pipe of the withdrawal line from the
network must not
never be less than that of the attachment of the machine;
- adequately fix the pipes, the weight of which must not
burden the device;
- properly insulate the pipes to get them
heat dispersion.
H)
Connect a special safety drain at the 1/2 “female threaded
connection of the safety valve.
F)
Once the indoor unit has been positioned, proceed with the
connection to the heating system using the pipes indicated below
to which you will have to apply 2 3/4 “tightening fittings contained
within the transparent package.
B)
Once the position of the fixings has been marked, make
appropriate holes for inserting the wall plugs to be chosen based
on the weight of the indoor unit in operation and based on the
structural type of the wall.
C)
Insert the fixing bracket again and tighten with the wall screws,
chosen on the basis of the indications given in point B.
D)
Hook the indoor unit without cover cabinet to the bracket just
fixed to the wall by positioning the “L” bracket already fixed to the
structure of the indoor unit
(see figure below).
E)
Firmly lock the indoor unit to the rear wall with 2 wall plugs
to be applied to the 2 holes in the vertical uprights(
see figure
below).

4.3 ASSEMBLY PROCEDUREA)
Place the wall fixing bracket on the wall where you want to install
the indoor unit.
Using a level, make sure that the bracket is perfectly horizontal
and that the support surface is regular.
Use the bracket as a template and mark the position of the holes
to be made.
