local dealer.
• Environments with large quantities of ma-
chine oil.
• Salty environments, such as coasts.
• Environments with high amounts of sulphur
gases, such as spa areas.
• Environments with high frequency machin-
ery, such as wireless equipment, welding ma-
chines and medical facilities.
• Environments that contain oxidising gases
and volatile matter.
• Environments with particular environmental
conditions.
• Environments with obstacles near the en-
trance and exit areas.
• Environments not suitable for maintenance.
• Environments that don't have the space indi-

DRILLING THE WALL AND MOUNTING
THE INSTALLATION PANEL.
Installation panel and right way up (unit: mm)
(Fig. 3-1 and 3-2).
• Fixing the installation panel (Fig. 3-3)
- Install the panel horizontally on the struc-
tural parts of the wall using the special
plate.
- If the wall is in brick, concrete or similar,
drill 5 mm diameter holes. Insert studs for
the mounting screws.
- Fix the installation panel on the wall.
• Drilling the wall
- Determine the position of the pipe hole
using the installation panel and drill a hole
(Ø95 mm) so that the pipe slopes slightly
downwards.
- Use a special guide for drilling metal rods,
laminated wood or metal plates.
INSTALLING THE CONNECTION AND
DRAIN PIPE
• Drainage
- Insert the drain pipe so that it slopes slightly
downwards. In (Fig. 3-4) shows the proper
installation and those that are not allowed.
- When connecting the drain pipe, insulate
the part connecting the extension with the
hard plastic pipe (Fig. 3-5).
• Connection pipe (Fig. 3-6)
- Install the left and rear left pipes as shown
below. Bend the connection pipe to a height
of 43 mm or less from the wall.

- Secure the end of the connection pipe (see
the tightening procedure in the section
on INSTALLING THE WATER PIPES).
When connected, cover all of the pipes
with heat-resistant material.
Note: bend and position the pipe carefully.
Ensure the pipe does not protrude from the
back of the indoor unit.
Make sure the drain pipe is connected correctly.
Insulate the supply and return pipes.
Pass the drain pipe under the supply pipe and
the return pipe.
In the event of supply and return piping con-
nections coming from the left side (looking at
the split front), we recommend using a cassette
tape to split predisposition, recessed to avoid
having joints hydronic bulwarks.
