h) Remove the stopper, lift the device slightly and lower it
in order to connect it to the plateis lower hooks resulting
in a perfectly sturdy fixture (fig. 10).
i)
Pull the appliance downwards and to the side to check
that it has been hooked up properly to the plate.
j)
Connect to the mains as indicated in paragraph 3.7.
k) Close the front panel once more, tighten the screws
inside the air outlet and the two screws within the upper
door.
l)
Check once again that the unit is perfectly level or,
at most, that it slants 2 mm towards the side where
condensation is drained.

Location selection of external unit
The external unitis location must be selected so that:
- The appliance is protected from direct sunlight.
- The base is strong enough to hold the weight of the
appliance; if, in order to carry out maintenence jobs, it is
necessary to stand on the base, then the said base will
have to be strong enough to hold both the person and the
appliance.
- The appliance remains above the base at a distance
equal to that of the maximum foreseeable snowfall.
- The appliance never remains exposed to heavy downpours
(as can happen when a drain pipe gets clogged up and the
gutter overflows).
- Sufficient space is left around the appliance to inable air
circulation and maintenance as specified in the overall
dimensions.
- Pathways are not obstructed.
- The appliance can be securely fixed to the base.
- Neither fumes nor noise emissions can disturb the
neighbourhood in any way. As regards noise levels, the
Hygiene Regulations in force on the site must always be
respected. If noise levels are too high, soundproofing
should be installed without obstructing neither air-
circulation nor maintenance.
- The appliance is facing prevalent winds according to fig.
11.
- The appliance is not in a leeward position as regards burnt
gas smoke stacks and does not undergo contact with
vapours and oily or corrisive gas emissions.
- The condensate can be easily removed (in the case of
heat pump appliances).
- The internal unit connecting lines (or internal units in the
case of the Multisplit series) are not longer than 15 m in
each direction (when more than 10 m, the charge must be
topped up with 25 g of R410A for each extra meter).
Furthermore, the maximum difference in height between
the external and internal unit (or in the case of Multisplit,
the internal units) is not more than 5 meters.
The external unit must be perfectly horizontal and therefore
before going ahead with its positioning it is essential to
ensure that the support surface is perfectly level.
If the appliance has to be installed in an overhanging
position on the wall it is advisable to use an "Assembly
