2. PIPING AND CONNECTIONS

WARNING:
- Do not drink the condensation water (personal injury from poi-
soning).
- Position the condensation drain pipe in such a way as to allow
for the correct downward fl ow of water in dedicated areas, and
to prevent any inconvenience or damage to people, things, ani-
mals, plants and structures.
- Use manual tools and equipment that are suitable for the in-
tended purpose.

2.1 Connecting the refrigeration piping

The piping can be positioned in different directions as indicated by
numbers 1, 2, 3, 4 in the adjacent fi gure. When the pipes are posi-
tioned in directions 1, 3, the special groove marked on the side of
the internal unit should be cut using a suitable tool. Turn the pipes
in the direction of the hole in the wall, taking care not to constrict
them in any way, and tape the refrigeration system piping, condensa-
tion drain pipe and electrical wiring together with electric (insulating)
tape, keeping the condensation drain pipe at the bottom so that the
water can fl ow freely.

2.2 Draining the condensation from the internal unit

The proper draining of condensation from the internal unit is funda-
mental for a good installation.
1. Keep the condensation drain pipe (diameter 16,5 mm) at the bot-
tom of the hole in the wall.
2. Make sure the condensation drain pipe has a continuous gradient
of approximately 3 cm per metre.
3. Do not include any traps in the condensation discharge piping.
4. Do not immerse the free end of the condensation drain pipe in wa-
ter and do not leave it in the vicinity of places emanating unpleas-
ant odours.
5. When the installation is complete, before switching on the appli-
ance, make sure the condensation drain pipe works properly by
pouring some water into the condensation drip water tray situated
inside the internal unit.

2.3 Draining the condensation from the external unit

The condensation or water that forms in the external unit during op-
eration in heating mode can be removed via the drain pipe fi tting.
Installation: fasten the drain pipe fi tting (diameter 16 mm) to the hole
on the bottom of the unit, as illustrated in the adjacent diagram. Con-
nect the condensation drain pipe to the drain pipe fi tting and ensure
the other end of the pipe is ducted into a suitable drain.
WARNING:
- Only use piping specifi cally designed for ACR air conditioning
units.
- Protect all connection cables and pipes in order to prevent their
being damaged.
- Never use pipes with a thickness of under 0.8 mm.
- The appliance must be installed in full compliance with national
system regulations.
- During the installation process, the refrigeration system should
be connected fi rst, followed by the electricity supply. In the
event of replacement, proceed in the reverse order.
