3 - POSITIONING
Operate in compliance with safety regulations in force.
For detailed information (dimensions, weight, technical
characteristics etc.) please refer to the TECHNICAL
INFORMATION section.
Use single protection devices : gloves, glasses etc.
During positioning consider these elements :
• technical spaces requested by the unit and the system
• choice of the unit installation place
• electrical connections
• water connections
3.1 PRELIMINARY INFORMATION
3.4 FRESH AIR PROBE
The external probe allows to automatically change the unit set
point according to the external enthalpy (temperature +
humidity).
It is then possible to optimize the unit energy efficiency.
3.2 FUNCTIONAL CLEARANCES
3.3 POSITIONING
The functional clearances have to :
• guarantee the unit good operating
• allow the maintenance operations
• safeguard the authorized operators and the exposed
person
Respect the functional clearances indicated in the
TECHNICAL INFORMATION - DIMENSIONS section.
Double the functional clearances if more units are aligned.
The unit has been designed to be installed :
• INDOOR
• in fixed position
• in premises with Max ambient temperature= 40 °C
(49 °C with “electrical panel ventilation” option)
• in premises with Max ambient RH = 50% at 40 °C
Limit the vibration transmission:
• use vibration isolators on the unit support points
• install the flexible joints on the water connections.
Installation criteria:
• safe accessible position
• avoid flood-prone places;
• verify the unit weight and bearing point capacity;
• verify that all bearing points are aligned and levelled
• install the unit raised from the ground
SAFETY VALVE GAS SIDE
The installer is responsible for evaluating the opportunity of
installing drain tubes, in conformity with the local regulations in
force ( EN 378 )
POSITIONING
The sensor should not be influenced by factors that can
distort the reading (eg direct sunlight, air exhausted from the
fan or other sources, contact with the unit structure or other
heat sources, accumulations of snow / ice).
Examples to position the external probe :
• A roof
• B under a terrace
• C if at free wall provide a small roofing
