12. Self Clean operation
13. Plasmacluster Ion function
Operating the Plasmacluster Ion button while the air conditioner is in
operation or in non-operation allows the switching of the operation
mode in the following sequence: “Air Clean operation”
→ “Stop”.
“Self Clean operation” generates about equal amounts of (+)ions
and (-)ions from the cluster unit to provide clean air.
If the Plasmacluster Ion generation function is operated together with
the air conditioner operation, the indoor unit fan speed and louver
direction are in accordance with the air conditioner settings.
If the Plasmacluster Ion generation function is used without operating
the air conditioning function, the indoor unit fan operates at a very low
speed and the upper louver is angled upward and the lower louver
remains horizontal. (The airflow volume and direction can be changed
by using the remote control.)
14. Auto restart
When power failure occures, after power is recovered, the unit will
automatically restart in the same setting which were active before the
power failure.

15. Explanation of cluster circuit
The cluster unit generates cluster ions, which are circulated through-
out the room by the air flow created by the blower fan (indoor unit fan
motor) in the air conditioner unit.
1) When microcomputer output turns "H," the Q11 output changes to
"Lo," turning ON the SSR2 and applying 100 V to the cluster unit for
the generation of cluster ions (positive and negative ions).

Heating or Fan operation and Cluster operation are performed simulta-
neously.
The judgment of whether Heating or Fan operation is used is based on
the outside air temperature at 3 minutes after the start of internal
cleaning.
The operation stops after 40 minutes.
During this operation the horizontal louver moves and stays two posi-
tions.
It turns to the lower direction and stays for 30 minutes.
Next moves upward and stays for 10 minutes.
