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. The
documentation for accessories supplied loose
included with each kit.
DANGER!
The machine is 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 personal protection gear.
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 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 that set out in
the EN 378-1 standard and in keeping with the requirements of the EN
378-3 standard. When selecting the installation site, risks posed by
accidental refrigerant leakage from the unit should also be taken into
consideration.
II.4.1.1 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 people's 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 that 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 concentrations of
refrigerant gas.
II.4.2

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 designed for outdoor installation. The unit should be installed
to comply with the minimum recommended clearances, bearing in mind
the access to water and electrical connections. 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.

WATER CONNECTIONS

II.5.1

CONNECTION TO THE SYSTEM

IMPORTANT!
The layout of the water system and connection of
the system to the unit must be carried out in
conformity with local and national rules in force.
IMPORTANT!
We recommend installing isolating valves that
isolate the unit from the rest of the system. Mesh
filters with a square section (longest side = 0.8 mm),
of a suitable size and pressure drop for the system,
must be installed. Clean the filter from time to time.
○ The unit is equipped with threaded male water connections and a
manual air bleed valve positioned inside the shell.
○ It is advisable to install intercept valves the isolate the unit from the
rest of the system. It is also advisable to install elastic connection joins.
○ It is essential to fit a metal mesh filter (square mesh of no greater
than 0.8 mm) on the unit return piping.
○ The water flow through the heat exchanger should not fall below a
value corresponding to a temperature differential of 8°C.
○ During long periods of inactivity, it is advisable to drain the water
from the system.
○ It is possible to avoid draining the water by adding ethylene glycol to
the water circuit (see Protecting the unit from frost).
