6 - INSTALLATION
6.1 - Warning
Before installing, make sure that the components are clean, and clean them if necessary.
Warning!
Follow the safety instructions (see § 2 - SAFETY INSTRUCTIONS).
6.2 - Selecting a location
■ Before setting up and connecting the unit, the installer must check the following points:
-The unit's earthquake resistance has not been veried.
-These units can be placed directly on at, level ground. The atness value must be the best possible, around one per
thousand.
-For outdoor installation, take into account the regulations in force and the weather conditions at the installation site
(risk of snow, height from the ground, risk of wind, etc.).
-The selected location must not be liable to ooding.
-Raise the unit to ensure that the unit's operation is not affected by a buildup of snow.
-Take into account the required height of the siphon, the slope and the length of the condensate drainage container.
-There are three support options:
• ADJUSTABLE FEET
• RISERS
• RISERS + CYLINDERS (Specications section 6.4)
-The unit must be perfectly level (see diagram in § 6.3 Assembling the blocks).
-The surface of the ground or structure must be strong enough to bear the unit's weight.
-For outdoor installation with no weather protection, the unit must be equipped with the roof option. Make sure this option
is tted.
-Leave sufcient space around and above the unit for servicing and maintenance operations (see dimensional drawing).
Take into account the space required to open the doors.
-Leave space equivalent to the total depth of the unit on the utilities side to allow internal components to be removed.
See dimensional drawing.
-Under normal indoor conditions of use, there is no need to x the unit to the oor.
-Under outdoor installation conditions, the unit must be xed to the oor (windproong).
■ Depending on the regulations in force in the storage and installation location, precautions must be taken, particularly for roof
installation, to ensure that the unit is stable (strong winds, earthquake, etc.). This may involve mounting on the ground or the support
frame.
-For indoor installation, the room must conform to the regulations in force at the installation site. In particular, if the unit is equipped
with a thermodynamic system, the room must conform to standard EN 378-3 or other specications governing the installation
location (outside EC).
-Connections must not place mechanical stresses on the unit.
-When connecting directly to the unit, the hydraulic pipes and air ducts must be held using supports close to their point of connection
on the unit (Fig. 1).

Duct
suspensions
Duct
bracket
Fig.1 Fig.2
Bracket
-The hydraulic control valve kits must be supported close to their point of connection on the unit (Fig. 2)
-No connection should obstruct the unit's access doors, hatches or drawers.
■ Dual-ow units should be installed so as to prevent direct recirculation between the discharge and intake nozzles.
■ For installation in very dusty environments or areas with high pollen levels, we recommend a system of pre-lters on the fresh air
intake. The air inlets should be positioned so as to minimise adverse effects on the quality of air entering close to local emissions,
such as discharge air, radon, smoke, odours or other disruptive sources (road trafc, garage doors, car parks and buses, tarmac,
human impacts, animals, whether dead or alive)
■ Freezing fog can very quickly block the fresh air inlet lters. Fit an air preheating system (option available) for temperatures between
approximately +3°C and -3°C.
■For units equipped with a gas heater (GGS or Make-Up type), the gas connection must be made by qualied personnel in accordance
with the regulations in force at the installation site.
15

Sound level
■ Our units are designed to operate quietly.
■ As soon as you begin designing your system, you should take into consideration the outdoor environment to estimate the radiated
noise, and the building type for the noise transmitted through the air and by solid materials.
■ To minimise solid-borne vibrations, we recommend tting anti-vibration mounts between the unit's support and frame (see diagram
below), exible connectors on the hydraulic pipes and exible sleeves on the ducts.
Have an analysis carried out by an acoustical engineer.
For units supplied in separate elements, a counter frame must be used to add anti-vibration mounts (Fig. 1) (Frame and mounts
supplied by the customer).
Fig.1
Firebreak:
Fire can spread between the supply and the return (e.g. through the heat recovery system or the mixing air).
Fit the mandatory safety devices based on the regulations in force at the installation site (e.g. re dampers).

6.3 - Assembling the blocks
Ensure sufcient servicing space to allow easy maintenance and assembly of the blocks.
The air inlets must be capped if installation is interrupted. A waterproof lm is recommended to prevent white rust.
Electrical safety
The components and cables must be selected in accordance with the regulations in force at the installation site.
Always comply with the overvoltage, pollution and insulation voltage categories set by the standards and regulations.
Take into account the altitude when selecting the components and cables
Reminder: For units delivered unregulated and installed in CE zones, CE certication for the complete assembled unit is the
responsibility of the person assembling it.
Make sure the ground is at for the purposes of installing the unit and connecting the blocks.
To ensure a tight seal between joined sections, they must be shimmed and levelled to compensate for any unevenness of the
mounting surface.

6.3.1 - Gasket removal procedure:
■ To ensure proper sealing, the gasket must be tted as a single piece.
■ The connection must be at the bottom, ideally in the centre, but not in a corner.
■ To guarantee optimal long-term integrity, the gasket must not be removed when taut.
■ Likewise in the corners, it must not be taut, but should form a rim inside the corner.
