INSTALLATION REQUIREMENTS
Before machine installation and commissioning, the people involved in this activity must have acquired the information
necessary to carry out these tasks, applying all the information collected in this book all the procedures reported in the
aforementioned norms and the provided requirements by the local law.
Do not allow unauthorized and/or unskilled personnel to access the unit.
2.1
Information about installation of systems with R134a and R513A
According to the standard EN 378-1-2016, any refrigerant system that contains R134a or R513A, can be installed without
any restriction in open air or machinery rooms. Anyway, the building owner or the end user shall ensure that that access
is permitted only by qualified and trained personnel, who is aware of the general safety precautions of the building.
It is recommended to satisfy all the requirements listed in the EN 378-3-2016 for the installation.
The refrigerant shall not be able to flow into any adjacent room, doorway, or exhaust system in the event of a leak.
It is advised to install a refrigerant detection system which works also during the normal operation of the refrigerant system:
in case of refrigerant leak indeed, it can activate the alarm and all the necessary emergency procedures until the machine
shutoff.
The alarm shall also advice the authorized personnel to take the necessary steps. The refrigerant leak detector shall be
supplied by the user because it is a key component of the sprinkler system of the entire building.
2.2
Information about installation of systems with R1234ze
This product can be equipped with refrigerant R1234ze(E) which has minimal impact to the environment, thanks to its low
value of Global Warming Potential (GWP).
