• The surface on which the appliance is installed must:
- Be permeable (soil, gravel, etc.).
- Be perfectly fl at,
- Support its weight easily.
- Allow a solid fastening base,
- Not transmit any vibration to the dwelling. Anti-vibration
blocks are available as an option.
• The wall bracket cannot be used where it is likely to
transmit vibrations. Installing the unit on the ground is
preferred.

Positioning Outdoor Unit
The outdoor unit must be raised at least 50 mm above
ground level. In areas prone to snow, this height should
be increased but should not exceed 1.5 m (fi g. 18).
- Fasten the outdoor unit by means of screws and
rubber tightening or toothed lock washers to prevent
them from coming loose.
In areas with heavy snowfall, if the inlet and
outlet of the outdoor unit are blocked with
snow, heating may become diffi cult and a
failure is likely to occur.
Construct a canopy or place the unit on a high stand
(local confi guration).
- Place the unit on a solid stand in order to minimise
impacts and vibrations.
- Do not place the unit directly on the ground as this will
cause problems.

Condensate drain pipe
The outdoor unit can generate a large volume
of water (called condensate).
If the use of a drain pipe is necessary (e.g., superposition
of the outdoor units) :
- Install the condensate drain tray (optional) for
models 3, 5, 6 and 8 only. Use the elbow provided
C
and connect a 16 mm-diameter hose / pipe for draining
the condensate.
- Use the stopper or stoppers provided
B
to block the
opening of the condensate tank.
Allow for the condensate to fl ow away under the force of
gravity (waste water, rain water, gravel bed).
If installation is carried out in an area where the
temperature stays below 0°C for long periods,
equip the drain pipe with trace heating to
avoid it icing up. Trace heating must heat not
only the drain pipe but also the bottom of the
appliance's condensate collection tank.
