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 verified.
- These units can be placed directly on flat, level ground. The flatness 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 flooding.
- 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 (Specifications 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 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).
- 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. 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 traffic, garage doors, car parks and buses, tarmac,
human impacts, animals, whether dead or alive)
■ 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.
