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.
Sharp edges and the surface of the condenser section

Switch off power supply, by opening the main switch,
before servicing the cooling fans and/or compressors.
Failure to observe this rule could result in serious
personal injury.
Do not introduce solid objects into the water pipes while
the unit is connected to the system.
A mechanical filter must be installed on the water pipe
connected to the heat exchanger inlet.
The unit is supplied with safety valves, that are installed
both on the high-pressure and on the low-pressure sides
of the refrigerant circuit.
It is absolutely forbidden to remove all protections of
moving parts.
In case of sudden stop of the unit, follow the instructions on the

- 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
Avoid installing the chiller in areas that could be
dangerous during maintenance operations, such as
platforms without parapets or railings or areas not
complying with the clearance requirements around the
chiller.
Noise
The unit is a source of noise mainly due to rotation of
compressors and fans.
The noise level for each model size is listed in sales
documentation.
If the unit is correctly installed, operated and manteined the
noise emission level do not require any special protection
device to operate continuosly close to the unit without any risk.
In case of installation with special noise requirements it could
be necessary to install additional sound attenuation devices.
Moving and lifting
Avoid bumping and/or jolting during loading/unloading unit
from the truck and moving it. Do not push or pull the unit from
any part other than the base frame. Secure the unit inside the
truck to prevent it from moving and causing damages. Do not
allow any part of the unit to fall during transportation or
loading/unloading.
All units of the series are supplied with lifting points marked in
yellow. Only these points may be used for lifting the unit, as
shown in the following figure.
Use spacing bars to prevent damage to the condensation
bank. Position these above the fan grills at a distance of at
least 2.5 metres.
Both the lifting ropes and the spacing bars must be
strong enough to support the unit safely. Please check
the unit’s weight on the unit nameplate.
The unit must be lifted with the utmost attention and care
following lifting label instructions; lift unit very slowly, keeping it
perfectly level.
Positioning and assembly
All units are designed for installation outdoors, either on
balconies or on the ground, provided that the installation area
is free of obstacles that could reduce air flow to the
condensers coil.
The unit must be installed on a robust and perfectly level
foundation; should the unit be installed on balconies or roofs, it
might be necessary to use weight distribution beams.
