Verification of correct installation and testing:
Check for any gas leaks from the seals or joints
made during the installation phase.
Check the good insulation of the connection pipes
between cabinet holder and remote condensing unit
(when foreseen).
Check the electrical connection.
Check absorption.
Check the standard pressures.
Check the water connection by regulating the pressu-
re valve during operation and the good circulation of
the condensing water (when the holding cabinet is
water-cooled).
Perform at least one complete preservation cycle
(reach the set temperature), and one manual defro-
sting cycle.
Inform the customer regarding the exact use
of the appliance with specific reference to use and
the requirements of the customer him/herself.
Installation and the start-up must be perfor-
med by authorised staff.

Fuse holders (C): they contain the fuses and they
allow the opening and isolating of the circuits.
Electronic boards (D): depending on the parameters
acquired, they command and control the various
devices connected to the machine.
