Supply power wire A:
Multipolar electric wire. Size and length of the suggested electric wire are showed on table “electrical data”. The wire
must be Mod. H07RN-F (according to CEI 20-19 CENELEC HD 22). Make sure the length of the conductors between
the fixing point and the terminals allows the straining of the conductors L, N before that of the grounding.
Connecting wire B (SHIELDED):
Bipolar electric shielded wire; size and length of the suggested electric wire are showed on table “electrical data”.
The wires have not to be lighter than Mod. H05VVC4V5-K (according to CEI 20-20 CENELEC HD21).
Connecting wire C (with ground conductor):
Multipolar electric wire; size and length of the suggested electric wire are showed on table “electrical data”. The
wires have not to be lighter than Mod. H07RN-F (according to CEI 20-19 CENELEC HD22).

●
Deoxidized annealed copper tube for refrigerant tubing connecting the units of the system; it has to be insulated with foamed polyethylene
(min. thickness 8mm).
●
PVC pipe for condensate drain pipe (ø int.18mm) in length suitable to let the condensate flow into the outside drainage.
●
Anti-freeze oil for flare connections (about 30g.).
●
Electric wire: use insulated copper wires of size and length as shown at paragraph “SYSTEM WIRING DIAGRAMS”.

L Tot. = Total tubing length (L1 + L2 + L3...)
Ln = Maximum tubing length of a single indoor unit (n=1,2,3...)
REQUIRED AMOUNT OF ADDITIONAL REFRIGERANT
For tubing 1/4 “ - 3/8” = 15g/m
For tubing 1/4 “ - 1/2” = 20g/m
For tubing Emix (3/8”) = 15g/m
LIMIT OF ELEVATION DIFFERENCE - OUTDOOR UNIT/INDOOR UNIT: 10m (H1, H2, H3, H4,H5, H6)
LIMIT OF ELEVATION DIFFERENCE BETWEEN INDOOR UNITS: 5m (H)
No additional charge of compressor oil is necessary.
