INSTALLATION INSTRUCTIONS

DANGER!
Installation must only be carried out by skilled
technicians, qualified for working on air
conditioning and refrigeration systems. Incorrect
installation could cause the unit to run badly, with a
consequent deterioration in performance.
DANGER!
The unit must be installed according to national or
local rules in force at the time of installation. The
documentation for accessories supplied loose
included with each kit.
DANGER!
The machines are designed for indoor installation.
Segregate the unit if installed in areas accessible to
persons under 14 years of age.
DANGER!
Some internal parts of the unit may cause cuts. Use
suitable individual protection devices.
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 M6
metric threaded bolts. Slots are provided in the base for this purpose.
II.4.1

INSTALLATION SITE REQUIREMENTS

The installation site should be chosen in accordance with the provisions
of Standard EN 378-1 and in keeping with the requirements of Standard
EN 378-3. When selecting the installation site, risks posed by accidental
refrigerant leakage from the unit should also be taken into
consideration.
II.4.1.1 Indoor installation
The service rooms destined for the installation of cooling units must
always be constructed in compliance with current accident prevention
legislation in the country in question.
Service rooms are not normally constructed exclusively for the
installation of cooling machines. In many cases, they may also house
equipment such as burners that run on gas, solid fuel or liquid fuel, with
a consequent increase in risks to personal safety.

CLEARANCES AND POSITIONING

IMPORTANT!
Before installing the unit, check the noise limits
permissible in the place in which it will be used.
IMPORTANT!
The unit should be positioned to comply with the
minimum recommended clearances, bearing in
mind the access to water and electrical
connections.
The unit is envisioned for indoor installation. 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.

IMPORTANT!
Incorrect positioning or installation of the unit may
amplify noise levels and vibrations generated
during operation.
The following accessories are available to reduce noise and vibration:
KSA - Anti-vibration mountings.
When installing the unit, bear the following in mind:
non-soundproofed reflecting walls near the unit may increase the
total sound pressure level reading near the appliance by as much as 3
dB(A) for every surface;
install suitable anti-vibration mountings under the unit to avoid
transmitting vibrations to the building structure;
make all water connections using elastic joints. Pipes must be firmly
supported by solid structures. If the pipes are routed through walls or
panels, insulate with elastic sleeves. If, after installation and start-up of
the unit, structural vibrations are observed in the building, which provoke
such strong resonance that noise is generated in other parts of the
building, consult a qualified acoustic technician for a complete analysis
of the problem.
