The R32 refrigerant gas is slightly inflammable and odour-
less. Carefully read the safety data sheet available from the 
dealer and see table "Minimum floor area" 

p. 9 inside 

the technical data paragraph and the installation manual of 
the indoor unit installed. 

Use pipes with the thickness indicated in the following table:

Maximum operating pressure 4.3 Mpa.

In case of a drop in excess of 5 m, a siphon must be installed 
every 5-7 metres.

The given measures are the maximum permitted values.

Cooling connections featuring shut-off valves are preconfig-
ured for flare connections.

Cooling lines must be as straight as possible and any neces-
sary bends must have a radius grater than 40 mm.

Use clean hoses. Make sure the inside is free of dust, resi-
dues, water.
