2 - INSTALLATION
2.1 Preliminary operations
To operate the ROOF COOLER, you need:
- Electrical network with voltage and frequency characteristics suitable for the machine, with earth
conductor and protection devices;
- Water supply connection. Required pressure: 2 to 4 bar
- Water drainage connection.
Connections to the electricity and water mains must be made by qualified personnel
in accordance with the safety regulations in force in the country of destination
.
2.2 Positioning
The ROOF COOLER must be positioned respecting the minimum recommended distances that allow
the correct operation of the machine and maintenance.
For optimal operation, the ROOF COOLER should be installed outside the building, as required:
-
on roof, flat or sloping, with bottom air outlet (Fig. 2.2.1)
-
wall-mounted, with side, bottom or top air outlet (Fig. 2.2.2, 2.2.3, 2.2.4)
For an efficient cooling action and for the control of the room humidity, it is essential to ensure a
continuous renewal of the air in the room to be cooled, by means of ventilation openings of suitable
size, placed at the maximum possible distance from the cooler(s), which must be kept open during
operation. Instead of, or in addition to openings, some air extractors can be installed, so that the
extracted air flow rate is at least 80% of the air flow rate introduced into the room by the cooler(s).
The efficiency of the process, and therefore the room temperature drop, will be greater the higher the
temperature of the outside air and the lower its relative humidity.
ATTENTION!
•
The installation must guarantee compliance with the requirements of standard UNI
EN ISO 13857:2008, with regard to protection against accidental contact by operators
with moving parts of the machine and the relevant safety distances
.
•
The ROOF COOLER must normally be connected to a ducting system. If the unit is
installed without ductwork, with the air outlet at a height of less than 2.7 m from the
floor, it is mandatory to install the fan protection grid P/N 2900501 supplied as an
accessory, or provide external protection (fence, etc.) to prevent access by
unauthorised persons. It is FORBIDDEN TO USE THE UNIT WITHOUT PROTECTION
GUARDS. DANGER OF CONTACT WITH MOVING PARTS!
•
The system must only be designed and built by qualified personnel, in accordance with
the legal, technical and work safety regulations in force in the country where the
appliance is to be used.
•
Regardless of the type of installation chosen, ensure that the structure and supporting
elements are able to safely support the weight of the cooler and its accessories. Have the
necessary structural verifications carried out by qualified personnel.
