Checking for gas leakage
• Check for leakage of gas after air purging
• 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.
• Cut the insulated portion of the on-site piping,
matching it up with the connecting portion.
• 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.
• Wrap the slit and butt joint with the included in-
sulation sheet, making sure there are no gaps.
Important Hints on Isolation
• Insulate the joint of the pipes securely. Incomplete insulation may lead to water leakage.
• Push the pipe inside so it does not place undue force on the front grille.
Connecting the drain hose
• Insert the supplied drain hose into the socket of
the drain pan.
• Fully insert the drain hose until it adheres to a
seat of the socket.
Check for leakage here:
• Apply soapy water and check
carefully for leaking gas.
• Wipe soapy water off after the
check is complete.
