2. Flaring Work and Connection of Piping
1) Flaring work
Main cause for refrigerant leakage is due to defect in
the flaring work. Carry out correct flaring work using the
following procedure.
the flaring work. Carry out correct flaring work using the
following procedure.
1. Cut the pipes and the cable.
• Use the piping kit accessory or pipes purchased locally.
• Measure the distance between the indoor and the
• Measure the distance between the indoor and the
outdoor unit.
• Cut the pipes a little longer than the measured
distance.
• Cut the cable 1.5m longer than the pipe length.
2. Burr removal
• Completely remove all burrs from the cut cross sec-
tion of pipe/tube.
• Put the end of the copper tube/pipe in a downward
direction as you remove burrs in order to avoid drop-
ping burrs into the tubing.

3. Putting nut on
• Remove flare nuts attached to indoor and outdoor
unit, then put them on pipe/tube having completed
burr removal.

• Firmly hold copper pipe in a die in the dimension
shown in the table above.
• Carry out flaring work using flaring tool as shown
below.

2) Connection of piping Indoor
• Preparing the indoor unit's piping and drain hose for
installation through the wall.
1. Route the indoor tubing and the drain hose in the
direction of rear left or right.
2. Tape the tubing, drain hose, and the connecting
cable. Be sure that the drain hose is located at the
lowest side of the bundle. Locating at the upper
side can cause drain pan to overflow inside the
unit.
lowest side of the bundle. Locating at the upper
side can cause drain pan to overflow inside the
unit.
NOTE: If the drain hose is routed inside the room,
insulate the hose with an insulation material* so that
dripping from "sweating"(condensation) will not damage
furniture or floors.
*Foamed polyethylene or equivalent is recommended.

3. Connecting the pipings to the indoor unit and drain
hose to drain pipe.
• Align the center of the pipes and sufficiently tighten
the flare nut by hand.
• Tighten the flare nut with a wrench.
• When extending the drain hose at the indoor unit,
install the drain pipe.
4. Wrap the insulation material around the connecting
portion.
• Overlap the connection pipe insulation material and
the indoor unit pipe insulation material. Bind them
together with vinyl tape so that there is no gap.
