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.
DANGER!
The machine is designed for outdoor 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 (EKSA), once it has
been set on the ground, it must be solidly bolted down to the floor using
M12 metric threaded bolts. 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. When selecting the installation site, risks posed by
accidental refrigerant leakage from the unit should also be taken into
consideration.
II.5.1.1 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.5.2
CLEARANCE SPACES, POSITIONING
