Safety
The unit must be firmly secured to the soil.
It is essential to observe the following instructions:
It is forbidden to access the electrical components
without having opened the main switch and
switched off the power supply.
It is forbidden to access the electrical components
without using an insulating platform. Do not access
the electrical components if water and/or moisture
are present.
The sharp edges can cause injuries. Avoid direct
contact and use adequate protection device
Do not insert solid object in the water pipes.
A mechanical filter must be installed on the water
pipe connected to the heat exchanger inlet.
The unit is supplied with high pressure switches
and/or safety valves, that are installed both on the
high-pressure and on the low-pressure sides of the
refrigerant circuit:
be careful.
It is absolutely forbidden to remove the protections
of moving parts.
In case of a sudden stop. follow the instructions listed in
the
Control Panel Instruction Manual
which is part of
the on-board documentation.
It is strongly recommended that the installation and
maintenance operations not be performed along but
with other people.
In case of accidental injury or unease, it is necessary to:
keep calm
Press the alarm button, if present at the installation
site, or open the main switch
move the injured person in a warm place far from
the unit and in rest position
contact immediately emergency rescue personnel of
the building or the Health Emergency Service
wait without leaving the injured person alone until
the rescue operators come
Give all necessary information to the rescue
operators.
Positioning and assembly
The unit must be installed on a sturdy and perfectly
level foundation. For the earthing, a resistant base is
cement must be created with a width greater than that
of the unit. This base must be able to support its
weight.
Anti-vibration supports must be installed between the
frame of the unit and the cement base of the steel
beams; for their installation follow the dimensional
drawing provided with the unit.
The frame of theunit must be perfectly levelled during
installation, if necessary using shims to be inserted
under the anti-vibrators.
Before the first start-up, it is mandatory that the
installation be verified as being level and horizontal
using a laser level or another suitable instrument.
The error in the levelness and the horizontal position
must not be greater than 5 mm per unit up to 7 metres
and 10mm per unit over 7 metres.
If the unit is installed in places that are easily accessible
to people and animals, we recommend that protection
grates be assemble all around to prevent free access.
To guarantee the best performance in the place of
installation, the following precautions and instructions
must be respected:
- Make sure to provide a strong and solid foundation to
reduce noise and vibrations.
- Avoid installing the unit in areas that could be
dangerous during maintenance operations, such as
platforms without parapets, railings or areas not
complying with the requirements to leave a clearance
space all the way around it.
Respect the minimum access distances around the unit:
- 1500 mm in front of the electric panel;
- 1000 mm on all the other sides.
