PREPARING TO INSTALL THE INDOOR UNIT

  • 

Fit the drain hose insulation 7

around the drain hose as shown in the diagram beside.

  • 

Attach the discharge chamber. (

) (10 screws)

  • 

Cut out the intake cut-out portions at the unit rear panel using a cutter or other tools to make openings.

  • 

Remove the two screws at the rear edge of the unit top panel and attach the intake chamber. (

) (8 screws)

Securing the Hanging Bolts

Switching the High State Switch (SW2)

  • 

To increase the air volume, open the control box and on the control board, switch the high state switch (SW2) to “HI”.

  • 

See the diagram for “Connecting the Indoor/Outdoor Connecting Cable”.

Installation into the Ceiling

  • 

Attach the nuts and washers to the hanging bolts, then lift up and hook the main unit onto the hanging fixtures.

  • 

Check if the unit is leveled using a level or a vinyl hose filled partially with water.
