WARNING
!
Only licensed installers and service technicians should perform the fuel gas piping.
Improper installation causes fire and explosion.
CAUTION
!
• A fuel gas port is fastened with an appropriate torque and shipped in a way that ensures it
will remain leak free. When connecting the gas piping, secure the connecting port in order
not to have excessive torque. Applying an excessive force when fastening can damage to
the gasket and cause a gas leak.
• Check for gas leaks from the fuel gas pipes after completing the installation.
Gas leaks cause hazards such as fire.
• Use a flexible hose when connecting to the outdoor unit.
There is a risk of gas leaks from a vibration of steel pipes.
