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 downfl 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 use.

2.1 Connecting the refrigeration piping

The piping can be positioned in 3 different directions as indicated with
numbers 1, 2 and 3 in the adjacent fi gure. When the pipes are posi-
tioned in directions 1 or 3, the special groove designed 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 (2), taking care not to constrict
them in any way, and tape the cooling piping, condensation 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 (ø 18,2 mm) at the bottom 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 turning on the appliance,
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. In-
stallation: fasten the drain pipe (Ø 15 mm) fi tting to hole on the bottom
of the unit, as illustrated in the diagram on the right. Connect 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 specially designed piping for ACR type air conditioning units
- Protect all connection cables and pipes in order to prevent them being damaged.
- Never use pipes that have a thickness which is less than 0,8 mm.
- The appliance must be installed in full compliance with national system regulations.
- During the installation process, the refrigerator should be connected fi rst, followed by the electricity supply. In
the event of replacement, proceed in the reverse order.
