Outdoor installation
If installation is outdoors it will be necessary to carefully select the position of the equipment, in
order to avoid noise pollution and fire hazards.
To minimize noise pollution, position the equipment as far from houses as possible and far from
possible noise-reflecting sources.
To minimize fire hazards, do not position the equipment next to flammable material. A fire event
would raise the pressure in the liquid receiver vessel and consequently cause a discharge of
refrigerant in the atmosphere.
Positioning the equipment with the electrical panel facing north will make reading the controller
display easier and will protect the polycarbonate casing.

Detectors and alarms
When plant rooms are near areas in which people are present on a regular basis, restricted areas of
difficult evacuation, detectors and alarms must be installed as established by standards EN378-3 in
order to speedily give warning of any hazardous concentration of cooling fluid vapor in the air.
Such devices must operate an attended alarm and/or a noticeable alarm that may enable the
consequent actions by the personnel.
Equipment serviceability
To access the system’s internal parts in versions with indoor and outdoor enclosure, it is necessary
to remove the casing panels using the appropriate key.
To set or service the electronic module (controller box), open the door using the appropriate key
that only the authorized technical personnel has.
Power connections
The electrical board was designed to operate on 380V-400V/3Ph/50-60Hz and 220V-
230V/3Ph/50-60Hz.
To select operating voltage it is necessary to relocate the jumpers on the auxiliary
transformer as appropriate.
The electrical board must be supplied power using a cable with a
cross-section suitable for the equipment’s power rating and for the laying conditions existing in
the place of installation.
The serial number plate on the machine shows, among other details,
maximum electric power. This value is also indicated in the relevant table, in the DESCRIPTION
/ TECHNICAL DETAILS section of this manual. It is the electrician’s duty to design the wiring
