CONNECTIONS

DRAIN PIPE CONNECTION
The indoor unit is fitted with a condensate drain pipe to
which a lagged drainage hose should be connected leading
to a suitable drainage outlet. The appliance is designed for
condensate drainage from either side, although the drain
pipe is connected in the factory on the left.
- Remove front panel as described in Maintenence section.
- Using a tool remove fixing spring located in left condesate
pipe.
- Remove plug present.
- Place fixing spring in right condensate pipe.
- Replace front panel
Connect a lagged drainage pipe (inside ø 16 mm) to the
hose fitting of the drain pipe and direct it towards a suit-
able drainage outlet.
After installation, check that the condensation flows out
regularly.
For data regarding installation, see the section "Informa-
tion for installation".
To access the connections, see the section "Access to
connections".
The drainage pipe must have a 3% slope downwards
towards the drain.
Check all the joints for leaks.
Apply heat-insulating material to the joints.
CONNECTION TO THE WATER SYSTEM
For connections at the sides:
- Remove the relevant knockout from the housing
For connections at the rear:
- Drill a hole Ø 60 in the wall within one of the two areas A"
(see section "Information for installation").
Pass a protective plastic pipe through the hole in the
wall.
Ensure that the section of wall in question has no bear-
ing structural members, pipes or electric cables.
Upon completion of work it is advisable to close the
holes made in the wall using elastic and, if possible,
soundproofing material.
- To facilitate carrying out the water connections, keep the
unit raised by means of a spacer.
- If necessary position the connections in the space provid-
ed at the rear of the indoor unit and fix them with the pro-
vided bracket A.
Position the pipes so that they occupy as little space as
possible in order to facilitate hooking of the appliance
onto the metal plate.
