PIPING AND CONNECTIONS
ATTENTION:
- do not drink the condensation water (personal injury from poisoning)
- Position the condensation drain pipe in such a way as to allow for the correct
downflow of water in dedicated areas, and to prevent any inconvenience or
damage to people, things, animals, plants and structures.
- Use manual tools and equipment suitable for the intended use (in particular,
make sure that the tool is not worn and that the handle is intact and fully fastened
to the rest of the tool); use them correctly and make sure they don’t fall from
a height. Put them safely back in place after use. (Personal injury from the falling
splinters or fragments, inhalation of dust, shocks, cuts, pricks and abrasions).
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 figure on the right. When the pipes are positioned 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, taking care not to constrict them in any way, and tape the copper
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 flow freely.
2.2 Draining the condensation from the internal unit
The proper draining of condensation from the internal unit is fundamental
for a good installation.
1. Keep the condensation drain pipe 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 water and
do not leave it in the vicinity of places emanating unpleasant 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 operation in
heating mode can be removed via the drain pipe fitting.
Installation: fasten the drain pipe fitting to the 25 mm hole on the bottom of the
unit, as illustrated in the diagram on the right.
Connect the condensation drain pipe to the drain pipe fitting and ensure the
other end of the pipe is ducted into a suitable drain.
ATTENTION:
-ONLY use copper pipes for ACR type air conditioning units or suitably insulated
copper pipes.
-Protect all connection cables and pipes in order to prevent their being
damaged.
-For R410A gas, use copper pipes with a suitable thickness
- Never use pipes that have a thickness which is less than 0,8 mm.
