5.4 Checking and replacing ultrasonic oscillator
The oscillator located at the bottom of the water
reservoir (round shape from top view) becomes worn
out after use and the producing mist volume will
decline. When it happen, renew the oscillator by
replacement.
1)
Shut the water supply valve and switch off the
electric power supply.
2)
Unscrew two flange nuts fixing the oscillator at
the bottom of the water reservoir from the outside.
(Use box type screw driver for 3mm- nut)
3)
Unplug two wires, yellow and orange colored one
from PCB (printed circuit board) and remove the
oscillator from the water reservoir.
4)
Put the new one and fix it using the same
3mm-nuts. Keep the balance of the tightening for
two nuts.
5)
Connect/plug in the two wires to the PCB
according to the color indication.

5.5 Caring strainer
Strainer must be set between the water line and the water inlet pipe to protect
the unit by eliminating the dirt or the dust.
1)
Close the water supply valve.
2)
Turn the knob of the strainer holder counter clockwise to remove the knob.
3)
Take out the strainer from the holder and clean up if there are dirt or dust.
4)
Return the strainer to the right place and shut it by knob.
CAUTION:
The safety fuse will burn out if switch on the unit without connecting the
oscillators.
REMARK:
The life of the oscillator is around 5,000 running hours in total. We recommend
you to change the oscillator for new one a little earlier than 5,000 hours.
CAUTION:
● Close the knob/cap firmly and tightly before test running or after maintenance
and Checking.
● Be sure not to have water inside of the strainer holder when close the know/cap.
Otherwise, the water pressure may twist the O-ring and it may cause water
leakage.
