• Make sure that the unit does not disturb the
surrounding area or inhabitants (noise level, draught,
low temperature of the ejected air freezing the plants
in its path).
• The surface on which the appliance is installed must:
- Be permeable (soil, gravel, etc.).
- Support its weight easily.
- Allow a solid fastening base,
- Not transmit any vibration to the dwelling. Anti-vibratory
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.
2.2.2 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 (gure 14).
- Fasten the outdoor unit by means of screws and
rubber tightening or toothed lock washers to prevent
them from coming loose.
" Warning
In areas with heavy snowfall, if the intake and outlet
of the outdoor unit is blocked with snow, heating may
become di󰀩cult and a failure is likely to occur.
Construct a canopy or place the unit on a high stand
(local con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.
2.2.3 Condensate drain pipe
(see gure 14)
" The outdoor unit can generate a large volume of
water (called condensate).
If the use of a drain pipe is necessary:
- Install the condensate drain pan (optional / code 074008)
for Alféa Extensa Duo A.I. models 5, 6 and 8 only.
- Use the elbow provided (C) and connect a 16 mm-diameter
hose for draining the condensate.
- Use the plug(s) provided (B) to block the opening of
the condensate drain pan.
Allow for the condensate to 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.
