B. Operating instructions
MW-05A DUAL is an Ionizer with two MW-05A ionizer fans, it has independent
five-stage adjustable ions quantity, independent Adjustable air volume and an
independent protection of high voltage output abnormal. By using with the accessory
AC adapter, MW-05A DUAL is suitable for 110Vac/220Vac supply voltage.
1. AC adapter installation
Please connect the plug of the accessory AC Adapter with 110Vac/220Vac power
outlet, connect with Y-type DC cable and insert Y-type DC cable plug into the DC IN
connector on the back of ionizer fan. Note: do NOT use non- accessory AC adapters.
2. Operation
MW-05A DUAL is an Ionizer with two MW-05A ionizer fans, it has sequentially
five-stage adjustable ions quantity and adjustable air volume, the two ionizer fans are
independent operation. The single fan operation rule is as follows:
2.1 Initial Stage
Turn the power switch ON, and the fan spins up. ‘POWER’LED and
‘H.V.’LED become light up. The ion number is zero in initial stage.
2.2 First stage
Push the ion quantity adjustment switch (ION ADJ) in the initial stage, MW-05A
DUAL will enter into first stage. The fan keeps spinning and the buzzer will beep
once. The ‘POWER’LED,‘H.V.’LED and four LEDs of ion quantity indicator
become light up. The generated ion number is largest in first stage.
2.3 Second stage
Push the ion quantity adjustment switch (ION ADJ) in the first stage, MW-05A
DUAL will enter into second stage. The fan keeps spinning and the buzzer will beep
once. The ‘POWER’LED,‘H.V.’LED and right-hand side three LEDs of ion
quantity indicator become light up. The generated ion number is secondly large in
second stage.

2.4 Third stage
Push the ion quantity adjustment switch (ION ADJ) in the second stage,
MW-05A DUAL will enter into second stage. The fan keeps spinning and the buzzer
will beep once. The ‘POWER’LED,‘H.V.’LED and right-hand side two LEDs
of ion quantity indicator become light up. The generated ion number is medium in
third stage.
2.5 Fourth stage
Push the ion quantity adjustment switch (ION ADJ) in the third stage, MW-05A
DUAL will enter into fourth stage. The fan keeps spinning and the buzzer will beep
once. The ‘POWER’LED,‘H.V.’LED and rightmost LEDs of ion quantity
indicator become light up. The generated ion number is little in fourth stage.
2.6 Initial stage
Push the ion quantity adjustment switch (ION ADJ) in the fourth stage, MW-05A
DUAL will re-enter into initial stage. The fan keeps spinning and the buzzer will beep
once.
2.7 Air volume control
The FAN ADJ knob is fan speed control, turn the knob in a clockwise direction
can increase air volume, in a counterclockwise direction can decrease air volume, if
knob turn to end of the counterclockwise, the fan speed will operation in low speed
and minimum air volume.

becomes light up and the buzzer sounds. If this abnormal condition is not solved
within 1 minute, MW-05A DUAL will be locked.
3.2 When the foreign object contacts the discharge needle unit, ‘ALARM’LED
becomes light up and the buzzer sounds. If this abnormal condition is not solved
within 1 minute, MW-05A DUAL will be also locked.
3.3 Holding the ion quantity adjustment switch (ION ADJ), the buzzer sounds until
release the ion quantity adjustment switch.

maintain proper function.
3. The discharge needle may have carbon deposits and consumption due to corona
effect. It is recommended to replace the discharge needle unit every 3 months or
when the static elimination performance is degraded.
4. Clean both side louvers by a soft brush or compressed air at least once a week.
If the filter is used, the filter cotton should be cleaned or replaced per month.
