of GB indoor unit
WARNING !!! The appliance must be installed
exclusively on a solid and vertical wall, which can bear
the weight.
In case of installation of the indoor unit in a place with a
temperature below 0 ° C, take the appropriate measures to
avoid the formation of ice in the hydraulic units.
The sections of the circuit will, in any case, be calculated
according to the normal methods, taking into account the
available flow-head characteristic reported in section 5.2.
The first ignition must be carried out by the authorized
Technical Assistance Service.
Also consider the following types of connection for the indoor
unit:
- connection to the net water system;
- connection to the central heating system;

6 - INSTALLATION
6.8 - Choosing the installation location
of STM outdoor unit
WARNING!!! Carefully choose the position of the
outdoor unit with respect to its vicinity, as it is a source
of noise.
For the installation of the outdoor unit it is good to keep in
mind some first information:
No obstacles must prevent the free circulation of air around
the outdoor unit (Figure 6-3).
Do not place the outdoor unit near the bedrooms.
Do not place the unit in front of glass walls.
Do not install the unit near balconies, etc.
Choose a location sheltered from strong winds or install
the outdoor unit at 90 ° with respect to the wind direction.
Avoid proximity to heat sources and exposure to sunlight.
Avoid proximity to combustible materials and air jets.
Avoid installation in dirty and polluted places, where volatile,
corrosive or flammable liquids or gases are present.
Make sure there is drainage around the unit to evacuate
condensate during the defrost function.
The installation of the outdoor unit in an aggressive saline
atmosphere decreases the useful life of the product.
Place the outdoor unit on a support (concrete base,
beam, concrete cubes, etc.) without fixed placements with
the room served, in order to avoid any transmission of
vibrations.
Ensure a sufficient distance from the floor (500 mm as
shown in Figure 6-9), in order to keep the unit above the
condensation water..
Always use a metal base, suitably raised from the ground,
so as to allow the condensate to drain correctly. The width
of the base must not exceed the width of the outdoor unit.
In the case of wall mounting, check the dimensions and
weight of the unit in order to choose the appropriate support.
Tighten all the nuts after fixing the support bracket, to avoid
damage to the unit.
The installer must check that the unit is firmly fixed.
The support bracket must be made of a material that does
not degrade over time.
Make slightly inclined holes for connecting the pipes (≥ 8°)
to prevent rainwater from penetrating inside.
WARNING!!! In heating , if the outdoor temperature
is above 14 ° C, the machine begins to reduce the power. In
cooling, the power is reduced if the outdoor temperature
is below 28 ° C or above 41 ° C.
