INSTALLATION- CONNECTIONS

REFRIGERANT CONNECTIONS

This air conditioner uses the R410A
refrigerant gas.
Before an y type of inter vention, c heck
the type of r efrigernat gas loaded in
the outdoor unit. Onl y use equipment
suitable for the gas used.
Do not use differ ent gas to r efill the
existing r efrigerant. T he follo wing must
be respected:
- Seal all open ends of the pipes with
a plug or other making sure it is
connected properly.
- Pay attention during the connection of
pipes making sure that w ater, dirt etc.
do not enter in to pipes or in the system.
- The pipes connected to the indoor and
outdoor unit must be new.
The thic kness of the pipes must be
0.8mm or more.
- Use only R410A refriger ant gas in
compliance with that alread y loaded
in the outdorr unit w hen refilling the
existing refrigerant gas. Never add oil to
the system.
- To prev ent accidental loading of other
gases, the outdoor units loaded with
R410A refriger ant gas are equipped
with a three w ay v alve connection
service with a diameter of (1/2"UNF).
To prepare the copper pipes, proceed as
follows:
- use copper pipes with a thic kness of
at least 0.8mm, new and thermically
isolated.

- cut the copper pipes to measure with a
pipe cutter;
- smooth the ends using a flaring end;
- isolate the pipes and insert the conical
nuts before countersinking;
- for countersinking use a conical pipe
flanger;
- check that the conical surface is centred
on the pipe, is smooth and does not
have an y fr actures and has a uniform
thickness.
- close the ends with tape so that dirt
does not enter.
For the refriger ant lines, proceed as
follows:
- Pay attention during the connection of
pipes making sure that w ater, dirt etc.
do not enter in to pipes or in the system.
- pass the lines, the condensate drain tube
and the electric cables throught the hole
prepared in the w all so that the ends
coincide with the units connection;
- make the refriger ant lines connections
in correspondance to the internal unit;

Do not install the unit in rooms w here
flammable gas is a vailable or acid or
alcaline substances that could damage
the copper or aluminium heat exchangers
or internal plastic components.
Do not install the unit in w ork shops
or kitc hens w here v apours mixed with
treated air could deposit on the exc hange
batteries, reducing performance or on the
internal parts of the unit damaging plastic
parts.
- shape the refriger ant lines to bring
them in correspondence to the external
unit connections (please do not create
refrigerant lines curv es with a r adius
below 100 mm to a void crushing the
pipe section
- before connecting the lines with the
unit, ensure that the position is final
and then proceed in tightening using
a spanner and a loc k nut to a void
torsions on the mac hine enclosure and
be careful to clean the surfaces of the
joints in order to ensure perfect contact
between the tightened surfaces;
- connect the v acuum pump to the gas
line's connecting pin
- do not open the cocks (the vacuum must
be done on the lines and on the indoor
unit)
- create a v acuum until reac hing 760

- once all abo ve steps ha ve been
completed and after ha ving, definitely,
disconnected the v acuum pump,
completely open the coc ks oper ating
the nuts using a 4 mm hexagon male
spanner;;
- replace caps and tighten them;
- after ha ving c hecked that ev erything
is correct and the position of the lines
are final, fasten the cables and the
refrigerator lines together and anc hor
them with clamps.
