REFRIGERANT PIPING WORK
See the installation manual supplied with the Multi outdoor unit for outdoor unit.
1 FLARING THE PIPE END
1. Cut the pipe end with a pipe cutter.
2. Remove burrs with the cut surface facing
downward so that the chips do not enter the pipe.
3. Put the flare nut on the pipe.
4. Flare the pipe.
5. Check that the flaring is properly made.
WARNING
Do not use mineral oil on flared part.
Prevent mineral oil from getting into the system as this would reduce the
lifetime of the units.
Never use piping which has been used for previous installations. Only use
parts which are delivered with the unit.
Do never install a drier to this R-410A unit in order to guarantee its lifetime.
The drying material may dissolve and damage the system.
Incomplete flaring may cause refrigerant gas leakage.
2 REFRIGERANT PIPING
1. Align the centres of both flares and tighten the flare nuts 3 or 4 turns by hand.
Then tighten them fully with the torque wrenches.
●
Use torque wrenches when tightening the flare nuts to prevent damage to
the flare nuts and escaping gas.
2. To prevent gas leakage, apply refrigeration machine oil on both inner and
outer surfaces of the flare. (Use refrigeration oil for R-410A)
●
Wrap only the gas line side with the sealing pad. Bend the pad over the
insulation for fitting (union) from above.
