Wiring Connection

1. Remove the valve cover from the outdoor unit.
2. Connect the connecting cable to the terminals as identified with their
respective matched numbers on the terminal block of indoor and
outdoor unit.
3. When connecting the connecting cable to the outdoor unit terminals,
make a loop as shown in the installation diagram of indoor and
outdoor unit to prevent water coming in the outdoor unit.
4. Insulate the unused cords (conductors) from any water coming in the
outdoor unit. Proceed them so that they do not touch any electrical or
metal parts.

Setting of Remote Control
Selector Switch
When two indoor units are installed in the separated rooms, it
is not necessary to change the selector switches.
Remote control selector switch
• When two indoor units are installed in the same room or
adjacent two rooms, if operating a unit, two units may receive
the remote control signal simultaneously and operate. In this
case, the operation can be preserved by setting either one
indoor unit or remote control to B setting. (Both are set to A
setting in factory shipment.)
• The remote control signal is not received when the settings of
indoor unit and remote control are different.
• There is no relation between A setting/B setting and A room/B
room when connecting the piping and cables.
