■Indoor Unit Fixing

•Thread the indoor unit piping and cable through the hole.

•Hang the top of the unit onto the upper ridge of them in mounting plate.

•Make sure that the unit is correctly hung in place by sliding it to the left, then to the right.

•Press the bottom left and bottom right hand corners of the unit against the mounting plate until the fixing prongs click into place in the retainers provided to that effect.

■Fixing and Piping

•Piping must be performed by qualified personnel according 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 cutter.

•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 structure.

NOTES

•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.

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 charge to be added per extra meter of piping length when more than 7.5 meters.

■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 boodies 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.
