OTHER INSTALLATIONS OF THE MURAL UNIT
The indoor unit may also be installed in the following positions:
1. With rear outlet to the left.
2. With side outlet to the left.
3. With side outlet to the right.
4. With outlet facing downwards.
To install the unit with rear outlet to the left, proceed as indicated below:
1. Drill a 70 mm hole near the outlet on the left.
2. Make the hydraulic connections between the pipes of the indoor unit and those
of the outdoor unit.
3. Re-position the pipes in the housing on the indoor unit and fix them with the rel-
ative plate as shown in the figure on the right.
To install the unit with outlets to the side or facing downwards, proceed as
follows:
1. Remove the pre-cut plate (1-Fig.3) near the desired direction.
2. Turn the pipes carefully and set them in the desired direction.
3. Make the refrigerant connections between the pipes of the indoor unit and those
of the outdoor unit.
CONNECTION PIPES
The pipes are wound and already flared at both ends. The dimensions are those
given in the "LIMITS TO THE LENGTH AND HEIGHT DIFFERENCE OF
COOLANT PIPES" section.
Route the coolant pipes as required, with as few bends possible. Use an
appropriate pipe bender and comply with a minimum bending radius to prevent
them from being squashed. Remember that the bending radius must not be less
than 3.5 times the outer diameter of the tube (Fig. 4).
If you do not wish to cut off any excess pipe after routing, wind it up so that the
coil axis is horizontal.
Bear the following indications in mind when installing the pipes:
• Take care to unwind the pipe in the direction in which it was wound.
• Wrap the two pipes together with tape before passing them through the holes
in the wall to prevent the insulation from being damaged and dust from infiltra-
