ELECTRICAL TERMINALS
At least once a year:
- Power down the machine, blow away any dust
from inside the unit, and check and tighten if
necessary the connections.
- Power up the machine, test the safety
mechanisms.
- An analysis of the terminal in operating mode can
throw light on any strange noises from the
contactors or other units. Foreign bodies can
disrupt the operation of the components and
causes noisy vibration.
To avoid accidents, remember that this type of
maintenance requires electrical expertise.
REFRIGERATION CIRCUITS
At least once a year, carry out an in-depth inspection
of the refrigerant circuits.
In addition, before each season (or every 3 months if
used permanently) the controls listed in the
maintenance contract must be performed, i.e. check
the refrigerant change, 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.
IN ACCORDANCE WITH THE LAW
REFRIGERATION FLUIDS MUST BE COLLECTED
DEGASSING INTO THE ATMOSPHERE IS
FORBIDDEN.
