Cure the wiring connecting port and remote controller connecting port with paste or heat
insulation so that insects or dust will not enter the unit
CAUTION
Do not bundle the remote controller cable, or wire the remote controller cable in
parallel, with the indoor unit connection wire (to the outdoor unit) and the power supply
cable. It may cause erroneous operation.
3. 7. Remote controller installation
• Install according to the installation manual for remote controller.
4. CASSETTE GRILLE INSTALLATION
• Install according to the installation manual for Cassette grille.
• Be sure to con
fi
rm there is no gap between the panel and main unit after installing the

5. 2. External input and output
5.2.1. External input
• Indoor unit functions such as Operation/Stop or Forced stop can be done by using
indoor unit terminals.
• “Operation/Stop” mode or “Forced stop” mode can be selected with function setting of
indoor unit.
• A twisted pair cable (22 AWG) should be used. Maximum length of cable is 150 m (492 ft.).
• Use an external input and output cable with appropriate external dimension, depending
on the number of cables to be installed.
• The wire connection should be separate from the power cable line.
