PLANNED MAINTENANCE
REFRIGERATION CIRCUITS
At least once a year, carry out an in-depth inspection of the
refrigerant circuits.

permanently) the tasks listed in the maintenance contract must
be performed, i.e. check the refrigerant charge, evaporation
and condensing temperatures etc...
This work must be carried out by a trained refrigeration
engineer. We shall therefore keep the details of the work and
the type of checks to be performed to a minimum.
