2.4. ROOM TEMPERATURE AND AIR EXCHANGE
2.6. ELECTRICAL CONNECTION
2.5. REFRIGERATION POWER
For the air condensed refrigeration units, operating
room temperature must not exceed 32 °C. The declared
performances are not guaranteed beyond this tempera-
ture.
The remote condensing units must be installed in appro-
priate rooms or outside, in a place sheltered from direct
sunlight. If needed, the installer must evaluate using a
cover or roof (in any case sufficient air exchange must
be assured).
For further details, see 8 vedi Table 2.

Install a differential automatic circuit-breaker switch
upstream every appliance, according to the Standards
in force in the Country of installation.
The power supply must be brought to the blast chiller electri-
cal control board, according to the data carried on Table 4.
The electrical power supply cables must have the
correct size and be chosen depending on the real
laying conditions;
The electrical cables must enter and be blocked in
the appropriate cable sleeve and laid adequately
depending on the installation ambient;
Each conductor must be inserted in the correspondi-
ng terminal;
The earth conductor must be connected directly to
an effective earthing system.
The manufacturing company declines all liabi-
lity and warranty obligations if persons are harmed
or appliances and objects damaged, due to incor-
rect installation and/or lack of compliance with laws
in force.
If the power supply cable is damaged, it must
be replaced by the manufacturer or by the technical
assistance service or anyhow by a person with a
similar qualification, in order to avoid every risk!!!

The size of the connection cables must comply with
the information contained in the electric data of the
technical files. The voltage of the plants must be
within the limit of +10% and voltage unbalance of
the phases must not exceed 3%. The electric power
connection must be carried out by qualified person-
nel, in compliance with the directives and laws of
the country where the unit is installed.
