1. Purpose
The air purifying control function is to alert
the user to trouble in the ionizing or air
purifying operation.
2. Description
Trouble is determined to have occurred
(indicated by the FILTER indicator) in the
following four cases.
1) When a count of 1000H has been
reached on the timer
2) When the panel switch has been set to
OFF by the opening of the air inlet grile,
etc.
3) When an abnormal discharge caused
by a symptom such as the build-up of
dirt has been detected while the air
purifier is ON
4) When the electric dust collector has not
been installed correctly
* Trouble case (2) or (3) is deemed to
have occurred when the action
concerned continues for more than
one second.
3. Operation
The sequence that FILTER indicator is
turned on are described in the left flow-
chart.
! When 1000H timer counts up, the
FILTER indicator keeps lighting even if
the operation is stopped by the remote
controller.
The timer is stored in memory of the
microcomputer, and the operation time
is cleared by filter RESET button on the
indoor unit or a power failure. (FILTER
indicator goes off.)
" A trouble detected within 1 minute after
activation of the air is immediately
judged as an error and the FILTER
indicator goes on.
# In case that 1 minute passed after
activation of the purifier, the purifier is
turned off while the PURE indicator
keeps ON. After 10 minutes passed,
restart the purifier and an error is
judged again.
