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 constructor has at your disposal
a refrigeration and air conditioning
service school. The principal aim
of this is to give operators and
maintenance 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.
