Description
1.
Purpose
The air purifying control function is to
alert
the user to trouble in the plasma purifier
operation.
2.
Description
Trouble is determined to have occurred
(indicated by the plasma purifier
lamp
indicator) in the following two cases.
1)
When the panel switch has been set to
OFF by the opening of the air inlet
gri
l
le, etc.
2)
When an abnormal discharge caused
by a symptom such as the build-up of
dirt has been detected while the air
purifier is ON
* Trouble case are deemed to
have
occurred when the action
concerned
continues for more than
one second.
3.
Operation
The sequence that plasma ionizer
purifier
lamp indicator is turned on are
described
in the left flowchart.
1) A trouble detected within 1 minute
after activation of the air is
immedi-ately judged as an error
and the plasma ionizer purifier
lamp indicator goes on.
2) In case that 1 minute passed after
activation of the plasma ionizer
purifier, it is turned off while the
PURE indicator keeps ON. After 10
minutes passed, restart the plasma
ionizer purifier and an error is judged
again.
12. Discharge temperature control
* When the breaker is turned [ON] (In restart time
after power failure) or RESET button is pressed
the air purifier is not turned on until the integrated
operation time of the indoor fan exceeds 1 hour
after operation start (It is nor the Plasma ionizer
purifier operation time).
It is the safety measures considering an incom-
plete drain when electric dust collector has been
cleaned with water.
1. Purpose
This function detects error on the
refrigerating cycle or error on the com-
pressor, and performs protective control.
2. Operation
Control of the compressor speed
The speed control is performed as
described in the left table based upon
the discharge temperature.
