1.4 WARNING
● Do not see the light of the UV lamp, It may cause loss of visual power.
● Do not touch any electric circuit during power on especially by wet
hands. It will get electric shock.
● All of electric cable/wire should not damage, processing, pulling or
forcibly bending.
It will cause electric leakage and make re or electric shock.
● All of electric cable/wire should not bind or tie not to cause electric
leakage or ring
● When you have noted smoking or abnormal smell, shut o electric
power source immediately and also o the power switch of the unit.
And manual valve for water supply should be closed. If you keep
running the unit it may cause re or electric shock. Then please report
it to your supplier immediately.
● Do not disassemble the unit except cleaning purpose and also do not
modify the unit. It may cause re or electric shock.
● Do not splash any water on the unit. It may cause short circuit or
electric shock.
● Be careful not to expose the light of UV lamp to the skin too long.
It will cause skin inammation.
● Do not move or shake the unit during the operation. It may cause
electric shock or leakage.
● Do not install or locate the unit where such as unstable or vibrating
places. It may cause fall down the unit and hurt the people around there.
● Do not install or locate the unit where dusty place , sun shine light
exposing directly, high temperature, close to re.
All are very risky for the re of the unit.
1. Introduction
Page 7 9124654 Service ManualUltra Sonic Humidier 30001322 2021
● Keep open through around the electric safety breaker to shut down the
power easily at any emergency cases.
● Use only specied electric power source and no other voltage required.
● Connect Ground without fail.
● Do not use megger tester for the electric circuit check.
It may cause out of order of the electric parts due to the high voltage.
● In case of using the unit at cold weather location, such as lower then
freezing point, all of water pipe lines should be protected from freezing.
Otherwise, pipes may brake due to the freezing.
● The life of the oscillator is about 5,000 hours. The life some times
become shorter because of the using conditions such as water itself,
or cleaning of the scale etc.
Timely replacement of the oscillator required.
● To keep clean inside of the water tank and inside of the blow o
duct hose, Clean up every three days. It may happen, the miscellaneous
germs or bacteria become breeding.
● Cut o the power source when you do the cleaning. Otherwise, It may
have Electric shock.
● Drain o all water of the water tank if you stop the running for a while.
Otherwise, it cause the oensive odor created by some bacteria and it
may aect health.
● Use only clean water for the unit. Other liquid may cause trouble of the
unit and make re or electric shock.

2. Installation
2.1 Water Supply
● Use 1/2 inch pipe for water supply. Install a water supply valve and
a strainer (80 mesh or ner) near the humidier unit to remove
impurities in water.
● Connect to the main unit the black pressure-tight tube and half union
that are supplied along with the unit.
Before connecting, be sure to ush out any oil and dirt that may be
inside the pipe work with running water.
● Insert the vinyl hose into the overow port to connect with the drain pipe.
● Leave the black cap on the drain port as is. (It is to be used for draining
at the time of repair or inspection.)
CAUTION:
Install a water shock absorbing device in the water supply line
where water hammering is likely to occur.
Page 9 9124654 Service ManualUltra Sonic Humidier 30001322 2021
Before Operating:
● Be sure the voltage of the power supply before starting the running.
● If you use the unit with humidistat, set the dial of the humidistat at your
expecting level.
Then switch ON the power of the unit.
● Open the valve of the water supply.
Operation:
The running order of the unit after switch on.
● Open the water supply valve and turn the power on to begin water
supply.
● When the water level reaches at the rst specied level, the oat switch
to prevent waterless operation is released and humidication will start.
● When the water level raise to reach the second specied level, the oat
switch for water supply is activated to stop the supply of water. After that,
as the water level lowers due to water consumption for humidication,
the water supply is resumed and this process repeats itself
automatically.
● When the water supply is cut o, the oat switch to prevent waterless
operation becomes activated and the humidication stops automatically.
● If the water pressure becomes abnormally high, it activates the oat
switch for water supply and it may start emitting a tic-tic noise, in which
case turn the valve own to adjust.
● Ensure there is no leak in any part of the pipe work.
CAUTION:
● Do not lift or move the unit while operating.
● Do not lay the unit on its side or upside-down. (This will cause a
waterless operation and damage the ultrasonic oscillator circuit.)
● Do not use a megger tester to check the circuit. (This may damage the
transistors)
3. Operation
Page 10 9124654 Service Manual Ultra Sonic Humidier 30001322 2021
3. Operation
WORKING AND ADJUSTMENT ULTRASONIC HUMIDIFIER
If you switch on the humidier the UV lamp turns on and the water tank
automatically lls up to the rst level with ltered water.
Now the oscillator starts to vibrate and the water molecules are blown out of
the unit, by means of the blower, as a very ne mist and this mist is spread
over the products.
The water tanks is lled up to the second level and then stops.
Now the water level drops to the rst level and is lled up again, and so on.
Points of attention:
- Inside the UV lamp there is a measuring cell.
If UV lamp is worn out the red indication lamp on the transformer is lit.
- UV lamp and oscillator have to be replaced every year.
- Outside on the water tank a clixon is placed as a safety. Set on 55°C.
- Clean the air lter under the water tap.
- Check the position of the adjusting plate slide on top of the humidier.
