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.  
For further solutions, please consult manufacturer 
representative.
