3.INSTALLATION OF THE COMPONENTS
SPLIT QUATTRO air-conditioners are composed by the compressor unit and by the evaporator. SPLIT 4
QUATTRO and SPLIT 8 QUATTRO are pre-charged with R134A and endowed with rapid couplings. The
refrigerant gas circulates between them through pre-charged copper pipes with rapid couplings for the con-
nection. The standard pipe connected to the evaporator is 70 cm long. It is possible to separate two units by
means of extension leads of different lenght. During the connection, observe the directions of labels on two
sides: “Compressor side” and “Evaporator side” according to the following outlet. Handle pipes carefully to
avoid breakages due to incorrect use. The least bending radius is 50 mm.
3.16- PRE-CHARGED GAS PIPES WITH RAPID COUPLINGS (only for SPLIT models)
Except SPLIT 4 QUATTRO and SPLIT 8 QUATTRO
models, all other models of SPLIT QUATTRO range
are not pre-charged.The connection between two
units is a “FLARE” type connection. So only qualified
personnel must carry out the discharge and the
charge of the system.
For the section of outlet and inlet pipes, it is necessary to follow carefully the directions on each SPLIT QUAT-
TRO unit.
3.17 - CONNECTING PIPES
It’s not VECO S.p.a. but the installer to provide the material
for this operation.
The flare must be perfect (without any burr or imperfection).
The lenght of the flare walls must be the same.
