6) Rotate the dry air volume adjusting knob while
checking the value in the dry air volume display and
adjust the dry air volume.
*The setting range of dry air volume is 0.2~0.75 m3/min.
Operate the unit within the setting range.
* *During spray drying the powder that cannot be
collected with the cyclone adheres to the outlet filter,
thereby lowering the dry air volume.
If necessary, rotate the dry air volume adjusting knob
to adjust the dry air volume.
*If the dry air volume is below 0.1m3/min, the abnormal
dry air volume alarm works and the dry air volume
alarm lamp blinks.
(The unit operation continues)
(Buzzer sounds in 1-sec periods)
If the dry air volume increases to more than 0.11
m3/min within 30 sec after the abnormal dry air
volume alarm starts, the alarm will be deactivated
automatically.
If the condition below 0.1m
3
/min continues for more
than 30 sec, the dry air volume alarm lamp changes
to illumination and all operations excluding agitation
stop. (Buzzer keeps ringing for 30 sec)
7) Press the spray air intake key.
Spray air supply lamp illuminates and supply of spray
air starts.
8)Rotate the spray pressure adjusting knob while
checking the value in the spray pressure display and
adjust the spray pressure.
*The spray pressure adjusting knob has a locking
mechanism. When adjusting pressure, lightly pull the
knob to unlock before operating it.
*The setting range of spray pressure is 20~250 kPa.
Operate the unit within the setting range.
**If spray pressure 0 kPa continues for 5 sec after start of
spray air supply, the abnormal spray pressure alarm
works and the value in the spray pressure display
starts blinking.
(The unit operation continues)
(Buzzer sounds in 1-sec periods)
If the condition 0 kPa still continues for another 30 sec,
all operations excluding agitation stop.
(Buzzer keeps ringing for 30 sec)
**If spray pressure goes up to 300 kPa or higher, the
abnormal spray pressure alarm works and all
operations excluding agitation stop. (Buzzer keeps
ringing for 30 sec)
