Checking for gas leakage
1) Check for leakage of gas after air purging.
2) See the sections on air purges and gas leak
checks in the installation manual for the outdoor
unit.

Attaching the connection pipe
• Attach the pipe after checking for gas leakage,
described above.
1) Cut the insulated portion of the on-site piping,
matching it up with the connecting portion.
2) Secure the slit on the refrigerant piping side
with the butt joint on the auxiliary piping using
the tape, making sure there are no gaps.
3) Wrap the slit and the butt joint with the included
insulation sheet, making sure there are no
gaps.
CAUTION
1)
Insulate the joint of the pipes securely.
Incomplete insulation may lead to water leakage.
2)
Push the pipe inside so it does not place undue force on the front grille.
