General Information

Safety recommendations

To avoid accidents and damage, the
following recommendations should
be observed during maintenance
and service visits:
1. The maximum allowable

pressures for system leak testing
on low and high pressure side are
given in the chapter “Installation”.
Always provide a pressure
regulator. 

2. Disconnect the main supply

before any servicing on the unit. 

3. Service work on the refrigeration

system and the electrical system
should be carried out only by
qualified and experienced
personnel.

Maintenance contract

It is strongly recommended that you
sign a maintenance contract with
your local Service Agency. This
contract provides regular
maintenance of your installation by a
specialist in our equipment. Regular
maintenance ensures that any
malfunction is detected and
corrected in good time and
minimizes the possibility that serious
damage will occur. Finally, regular
maintenance ensures the maximum
operating life of your equipment. We
would remind you that failure to
respect these installation and
maintenance instructions may result
in immediate cancellation of the
warranty.

Training

The equipment described in this
manual is the result of many years of
research and continuous
development. To assist you in
obtaining the best use of it and
maintaining it in perfect operating
condition over a long period of time,
the manufacturer has at your
disposal a refrigeration and air
conditioning service school. The
principal aim of this is to give
operators and technicians a better
knowledge of the equipment they
are using, or that is under their
charge. Emphasis is particularly
given to the importance of periodic
checks on the unit operating
parameters as well as on preventive
maintenance, which reduces the cost
of owning the unit by avoiding
serious and costly breakdown.
