WARNING
Both the lifting ropes and the spacing bar and/or scales must be strong enough to support the machine safely.
Please check the unit’s weight on the machine’s nameplate.
The weights shown in the "Technical data" tables in the "General Information" chapter refer to standard units.
Some specific machines might have accessories that increase their overall weight (heat recovery, etc.)
WARNING
The machine must be lifted with the utmost attention and care. Avoid jolting when lifting and lift the machine very
slowly, keeping it perfectly level.
Positioning and assembly
All units are designed for installation indoors. The machine must be installed on a robust and perfectly level foundation; should the
machine be installed on balconies or roofs, it might be necessary to use weight distribution beams.
For installation on the ground, prepare a strong cement base that is at least 250 mm wider and longer than the machine. Also, this
base must be strong enough to support the weight of the machine as stated in the technical specifications.
If the machine is installed in places that are easily accessible to people and animals, it is advisable to install protection gratings for
the compressor section.
To ensure the best possible performance on the installation site, the following precautions and instructions must be followed:

Make sure to provide a strong and solid foundation to reduce noise and vibration as much as possible.

The water in the system must be particularly clean and all traces of oil or rust must be removed. A mechanical water filter
must be installed on the machine
’s inlet piping.
Minimum space requirements
Every side of the machine must be accessible for all post-installation maintenance activities. Figure 2 shows the minimum space
necessary.

Ventilation
The temperature of the room where the unit is placed should be always maintained between 0°C and 40°C.
Sound protection
When sound levels require special control, great care must be exercised to isolate the machine from its base by appropriately
applying anti-vibration elements (supplied as an option). Flexible joints must be installed on the water connections, as well.
Water piping
Piping must be designed with the lowest number of elbows and the lowest number of vertical changes of direction. In this way,
installation costs are reduced considerably and system performance is improved.
The water system must have:
