INSTALLATION INSTRUCTIONS

DANGER!
Installation must only be carried out by skilled
technicians, qualified to work on air conditioning
and cooling systems. Incorrect installation could
cause the unit to run badly, with a consequent
noticeable deterioration in performance.
DANGER!
The unit must be installed according to national or
local rules in force at the time of installation. If the
installed unit is accessible to persons below 14
years of age, use protective grilles or other devices
to prevent all possibility of contact. The
documentation for accessories supplied loose
included with each kit.
DANGER!
Do not lean on the heat exchange coil and the
corners of the structure as improper use could lead
to cuts. Use suitable personal protection (gloves,
eye protection etc).
DANGER!
When the outdoor temperature is around zero, the
water normally produced during the defrosting of
the coils could form ice and make the flooring near
the installation area slippery.
If the unit is not fixed to anti-vibration supports (KSA), once it has been
set on the ground, it must be solidly bolted down to the floor using M10
metric threaded bolts (Fig. 12). Slots are provided in the base for this
purpose.
II.5.1

INSTALLATION SITE REQUIREMENTS

The installation site should be chosen in accordance with that set out in
the EN 378-1 standard and in keeping with the requirements of the
EN 378-3 standard. The installation site should also take risks posed by
accidental refrigerant leakage from the unit into consideration.
II.5.2

OUTDOOR INSTALLATION

Machines designed for outdoor installation must be positioned so as to
avoid any refrigerant gas leakage entering the building and posing a
hazard to peoples health.
If the unit is installed on terraces or building roofs, adequate safety
measures must be taken in order to ensure that any gas leaks cannot
enter the building through ventilation systems, doors or similar
openings.
In the event in which the unit is installed inside a walled-in structure
(usually for aesthetic reasons), these structures must be suitably
ventilated in order to prevent the formation of dangerous refrigerant gas
concentrations.

CLEARANCE SPACES, POSITIONING

The unit is designed for outdoor installation. It should be installed in
compliance with the minimum recommended clearances, bearing in
mind access to water and electrical connections on the left-hand side of
the machine. The unit should be correctly levelled and positioned on a
supporting surface capable of sustaining its full weight. It must not be
installed on brackets or shelves.
