12.1.8 Switching the High State Switch (SW2)
To increase the air volume, open the control box and on the control board, switch the FAN switch (SW2) to “HI”.
See the diagram for “Connecting the Indoor/Outdoor Connection Cable”.
12.1.9 Note: Enabling long-range remote control
To maintain EMC emission limits, cabling interconnecting the HA terminal and subsequent opto-coupler, must be
no more than 1.9 m length.
Loop four turns of this cable through a suitable small EMC ferrite toroid, and protect with a short length of large
diameter heat-shrink tube.
There is no similar length limit for cable following on from the opto-coupler isolation.
12.1.10 Check the Drainage
Check after connecting the power supply.
Pour approximately 600 cc of water into the drain pan of the main unit using a squeeze bottle, etc.
Press the drain test run switch on the control board in the control box to start the drain motor and check whether
the water drains normally.
(The drain motor operates for approximately 5 minutes and then stops automatically.)
(See the diagram for “Connecting the Indoor/Outdoor Connection Cable”.)
