Section 2
Avoid:
•
direct exposure to sunlight;
•
closed sites with high tempuratures and poor air
circulation;
•
indoor environments at high temperatures and poor air
circulation, and avoid installing the machine near any
heat sources
3.4 - Ambient temperature and air exchange
For air cooled liquid chillers, the ambient operating
temperature must not exceed 90°F (32°C). Above this
temperature the declared performance is not guaranteed.
The machine can operate safely up to a temperature that is
referref to by the climate class indicated on the serial plate.
Remote condensing units must be instaled in special rooms
or, if outdoors, in a place protected from direct sunlight,
from adverse weather conditions and from heavy wind
(above 5m/sec). Where circumstances so require, it is the
responsibility of the installer to evaluate the use of a cover
or canopy (costs to be borne by the purchaser). In any case
sufficient air circulation must be guaranteed.
3.5 - Hydraulic connection for water cooled condensing
units
It is advisable to install a valve between the mains and
the appliance's inlet hose in order to be able to stop the
passage of water if necessary.
For appliances with water cooled units the water supply
temperature must be between 50°F (10°C) and 86°F (30°C)
and the operating pressure must be between 0.1 MPa (1 bar
- 14psi) and 0.5 MPa (5 bar - 72 psi).
3.6 - Electrical connection
No responsibility is accepted for damage to
,
persons, animals or property cause by failure
to earth the appliance and the creating of an
electrical installation that does not comply with
current standards.
The mains connection must be made according to existing
national rules and by experienced, qualified personnel.
Before connecting the appliance to the mains make
sure that the mains voltage corresponds to the voltage
indicated on the data plate.
Verify that the electrical installation is adequate to the
maximum power of the appliance, as indicated on the
plate. Upstream of each device it is mandatory to install
a differential thermal breaker according to current
Part Number: 9294045 07/19
,
regulations in the country of installation.
The electric connecting cables must be dimensioned
in accordance with the rules in force in the country of
installation. In cases wwhere the power cord of the
appliance is damaged, it must be replaced with another
with characteristics that comply with the rules in force in
the country of installation and performed by a qualified
personnel in order to prevent any risk to persons.
The earthing conductor must be correctly connected to
an efficient earthing system.
The manufacturer declines any responsibility and any
warranty obligation in the event of damage to the
equipment, to persons and property caused by incorrect
installation and/or failure to respect the applicable laws.
3.7 - Remote group refrigerator connection
The diameters of the supply lines of the equipment
are sized for distances of up to 10 meters. Contact the
manufacturer for longer distances.
3.8 - Condensate drainage connection (if applicable)
It is necessary to provide a drainage pipe for the
condensation and washing water of a minimum diameter
of 1". It is advisable to dispose of the condensate through an
open drain at ground level and fitter with a siphon with a
minimum diameter of 1/2".
3.9 - Notes for the installer
•
Verify the correct installation and system testing before
starting up the machine (test report).
•
Check for any gas leaks from the welds or joints made
during the installaition phase.
