Flaring work and connection
of piping
1 Flaring work
The main cause for gas leakage is due to defects in flaring
work. Carry out flaring work using the following procedure.
A Cut the pipes and the cable.
• Use the piping kit accessory (if applicable) or the pipes
purchased locally.
• Measure the distance between the indoor and the
outdoor unit.
• Cut the pipes a little longer than measured distance.
• Cut the cable 1.5m longer than the pipe length.
B Burrs removal
• Completely remove all burrs from the cut cross section
of pipe/tube.
• Place the end of the copper tube/pipe in a downward
direction as you remove burrs in order to avoid dropping
burrs into the tubing.
C Putting flare nut on
Flare nut
• Remove flare nuts attached to indoor and outdoor
unit, then put them on pipe/tube having completed

Note: It is not possible to put them on after flaring work.
D Flaring work
• Carry out flaring work using flaring tool as shown below.
Ensure the flaring tool is suitable for R410 refrigerant and
in good condition. Refrigerant leaks from poorly made
flares are not covered by the product warranty.

Hold copper pipe firmly in a die according to the dimension
show in the table above.
E Check
• Compare the flared work with the adjacent diagram.
• If flare is found to be defective, cut off the flare section
and do flaring work again.
2 Connection of pipes – Indoor
• Prepare the indoor unit's piping and drain hose for
installation through the wall.
• Remove the tubing retainer (see illustration below) and
pull the tubing and drain the hose away from chassis (if
required). For some models this is not needed.
• Replace the tubing retainer in its original position.
