Installing the indoor unit
INSTALLATION INSTRUCTIONS
Checking for gas leakage
1) Check for leakage of gas after purging air
2) See the sections on air purges and gas leak checks in the
installation manual for the outdoor unit.
1) Thoroughly insulate the joint of the pipes.
Incomplete insulation may lead to water leakage.
2) Push the pipe inside so it does not place undue force on the
front grill.
Connecting the drain hose
Insert the supplied C drain hose into the socket of the drain pan.
Fully insert the drain hose until it adheres to a seat of the socket.
CAUTION
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 butt joint with the included insulation sheet, making sure there are no gaps.
Check for leakage here
• Apply soapy water and check
carefully for leaking gas.
• Wipe soapy water off after the
check is complete.
