INSTALLATION

OBLIGATION
All the phases of installation must be covered in the general project.
Before starting these phases, in addition to defining the technical requirements, the person
authorised to perform the work must, if necessary, implement a "safety plan" to safeguard
the safety of the people directly involved, and strictly implement the safety rules and, in
particular, the laws that apply to mobile construction sites.
Before installation, check:
• that the area is perfectly flat and can ensure long-term stability;
•
that in case of installation on a raised building floor, this is of adequate capacity;
•
that it is easily accessible to all people who must interact with it during its expected
useful life;
• that it is possible to perform all maintenance and replacement operations (routine
and extraordinary) easily and without risks to people, and in compliance with the
laws in force concerning safety at work.
•
that the volumetric spaces are adequate to ensure appropriate air flow for correct
machine operation and ventilation;
•
that the minimum space requirements for operation and inspection indicated in this
manual are ensured;
•
that air intake and delivery are never hindered or obstructed, even partially.
The machine must be installed indoors, in a non-aggressive atmosphere.
OBLIGATION
The unit must be installed according to the requirements of
standard EN 378-3 and the local regulations in force, in particular
taking into account the category of occupation of the premises and
the safety class defined by EN 378-1.

OBLIGATION
The machine must be placed in an area only accessible by
OPERATORS, MAINTENANCE PEOPLE and TECHNICIANS; if this is
not possible, it must be surrounded by a fence that is at least two
metres from the external surface of the machine (if possible).
The staff of the INSTALLER or any other visitors must always be
accompanied by an OPERATOR. Under no circumstances, must
unauthorised personnel be left alone in contact with the machine.
The MAINTENANCE MAN must limit him/herself to the controls of
the machine only; the only panel that can be opened by him/her is
the one that accesses the control module - no other must be
touched. The INSTALLER must limit him/herself to connecting the
plant to the unit.
Access the machine using the relative personal protective
equipment and only after having read and understood the
documents and instructions, which must always be kept close at
hand.
2.2.1

OVER POSITIONING

The machine is placed directly on the floor.
It is advisable to place an elastic rubber seal between the base of the machine and the
floor, covering the entire support surface, to prevent the transmission of noise and
vibrations.
Once the machine has been positioned, it must be checked that it is level.
A level deviation of more than 5 mm between the ends of the base may cause the
condensate to overflow from the collecting tray.

UNDER MACHINE POSITIONING

The machine is placed directly on the floor.
It is advisable to place an elastic rubber seal between the base of the machine and the
floor, covering the entire support surface, to prevent the transmission of noise and
vibrations.
Once the machine has been positioned, it must be checked that it is level.
A level deviation of more than 5 mm between the ends of the base may cause the
condensate to overflow from the collecting tray.
