2.4. ENVIRONMENTAL TEMPERATURES AND AIR EXCHANGE
2.6. ELECTRICAL CONNECTION
2.5. COOLING CAPACITIES
For air-cooled chiller units, the temperature of the
operating environment must not exceed
30°C
. The
performance declared is not guaranteed above this
temperature.
The remote condensing units must be installed in oppo-
site rooms or outdoors, in a place protected from direct
sunlight. If the circumstances should make it necessa-
ry, the installer must evaluate whether the use of a
cover or roof is required (in all cases sufficient air
exchange must be guaranteed).

Install an automatic differential circuit breaker switch
upstream from every appliance, for omnipolar discon-
nection of the power supply, according to the Standards
in force in the country of installation.
The dimensions of the connection cables must be in
compliance with the information contained in the electri-
cal data on the technical data sheets. The voltage of
the systems must be within the limit of +10% and the
voltage distortion of the phases must not exceed 3%.
The electrical power connection must be performed by
qualified staff, in compliance with the directives and
laws in the country of installation. The power supply is
to be taken to the electrical control panel of each single
appliance, according to the data in
Table 5
.
The electrical power supply cables must be correctly
sized for the units installed;
The electrical cables must be laid and blocked in the
relevant cable gland and installed properly according
to the place of installation;
Every wire must be inserted into the corresponding
terminal;
The earth wire must be correctly connected to an
efficient earthing system.
