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.
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 diff erent directions as indicated by
numbers 1, 2, 3, 4 in the adjacent fi gure. In case of confi guration “1”,“3”
remove plastic cover. Turn the pipes in the direction of the hole in the
wall, taking care not to constrict them in any way, and tape the re-
frigeration system piping, condensation drain pipe and electrical wir-
ing 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 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 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.
NOTE: The condensation drain tube is pre-installed on the same side
as the refrigeration pipes. The internal unit, however, has a further
housing, sealed by a rubber plug, on the opposite side to the refrig-
eration pipes. It is, therefore, possible to swap the positions of the
drain tube and the rubber plug, making sure that the plug is correctly
fi tted to avoid water leakage
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 fi tting (diameter 16 mm) to the hole on
the bottom of the unit, as illustrated in the adjacent diagram. 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.
