OUTDOOR UNIT

■Fixing and Piping

•Piping must be performed by qualiﬁed personnel ac-

cording to good refrigeration systems practices.

•Piping materials and insulation materials must be of

refrigerant quality.

•Select the pipe diameters according to the size of unit

and cut the pipe to design length by using pipe cut-

ter.

•Install the ﬂare nuts and ﬂare the end of the pipes.

•Check that no foreign bodies are inside the piping.

•Align the central of the connecting pipes and tighten

the ﬂare nut.

•Fix piping with pipe clamps and check that any pipe

vibrations cannot be transmitted to the building struc-

ture.

•Connect the pipe correctly.

•Do not apply the excessive torque.

•Use an appropriate bending tool to form curves and

avoid over-tightening the refrigerant tubes.

•To prevent heat loss, the two lines must be insulated

separately.

■Maximum Piping Length

The suction line must have a 2% gradient up to the

compressor on horizontal sections.

Where piping lengths are unusually long and include a

large number of oil traps, it may be necessary to adjust

to compressor charge.

■Refrigerant piping connections

(FLARE connections)

To avoid alteration of unit capacities, check that piping

lengths and changes in elevation are kept to a strict

minimum.

Before connectiong the refrigerant lines, follow the

procedures below (if pre-charged connection lines are

not supplied):

•Select copper pipe diameters according to the size of

unit to be installed.

•Install the refrigeration lines, checking that no foreign

bodies get inside the piping.

•Install the ﬂare connectors and ﬂare the ends of the

pipes.

•Evacuate the piping. This operation, which should last

at least 15 minutes if there are large piping lengths and

changes in elevation, should be followed by a leak test.

Refrigerant charge to be added per extra meter

of piping length when more than 7.5 meters.
