6. Installation
Unpack the unit taking care to not damage its exposed parts. Before discarding the packaging,
make sure no parts or documents have been left inside. Check that the supply voltage is as
designated.
DANGER
Before starting work, disconnect the power supply. Prior to drilling holes or making cuts, make
sure that holes, screws, cables, etc. do not interfere with the equipment which has already been
installed.
The installation and handling of cooling units may be hazardous as they form a pressurised system
with electric components. Only skilled personnel may repair, inspect or maintain the cooling units.
6.1. Positioning the unit
Indoor part
Indoor part (evaporating unit) must be installed inside the room to be conditioned, horizontally (fixed
to the ceiling) or vertically (fixed to the wall).
Check that:
• There is enough space for easy application, installation and maintenance, both inside and
outside the shelter. Always observe the minimum spaces indicated in the drawings in paragraph
"Drawings".
• In case of horizontal installation, the roof of the shelter can support the weight of the indoor unit;
• In case of horizontal installation, the ceiling is not inclined towards one lateral side or the side with
air discharge;
• In case of vertical installation, the wall can support the weight of the indoor unit;
• The room to be conditioned is clean on the inside;
• The structure is watertight;
• The inside of the room allows a proper air circulation, preventing any re-circulation.
According to the kind of ceiling (or wall), use an appropriate fixing system for the indoor unit. With
concrete or brick walls, use expansion clamps. With other kinds of wall, use through clamps, sealing
them from water (rain) infiltration, or fix the indoor unit to a suitable structure prepared in advance.
In case of vertical installation it's necessary to install the deflector, which is supplied loose, to collect
the moisture,as shown on the drawing in the following page.
The rear side of the indoor unit must be installed with a minimum distance from the wall, please refer
to the measures indicated in the drawings in paragraph "Drawings".
