Flexible sleeve Support
- 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-flow 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-filters on the fresh
air intake.
Freezing fog can very quickly block the fresh air inlet filters. 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 qualified personnel in
accordance with the regulations in force at the installation site.
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 fitting anti-vibration mounts between the unit's support and frame (see
diagram below), flexible connectors on the hydraulic pipes and flexible sleeves on the ducts.
- 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 fitted.
- Leave sufficient 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 fix the unit to the floor.
- Under outdoor installation conditions, the unit must be fixed to the floor (windproofing).
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 specifications 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).

EN - 8
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. 2) (Frame and mounts supplied by the customer).

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 sufficient servicing space to allow easy maintenance and assembly of the blocks.
The blocks must be assembled in accordance with the instructions in this manual.
Electrical safety – CE marking
The manufacturer cannot declare units supplied unassembled (flat) as compliant with the low voltage or EMC directive.
Units without control systems must be electrically connected by the customer.
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 installed in CE zones, CE certification for the complete assembled unit is the responsibility of the person
assembling it, unless the latter is a subcontractor.
Make sure the ground is flat 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.
