6. TROUBLE-SHOOTING
6.1When the unit get in trouble, check the following point first.
Troubled function
Possible reason
Countermeasure
No water supply.
The valve of water line is
closed.
Open the valve.
No operation.
No electric power.
Check with tester.
Off the power switch of
transformer box.
Switch on.
Turn on the UV malfunction
indicator lamp.
Replace the UV lamp
Burn out the fuse.
Replace to spare fuse.
Wrong setting of humidistat
or higher humidity than
setting level.
Reset the humidity level of
the humidistat (set higher
level for test and then set to
proper level.)
Less out put the mist.
There are water in the duct
hose.
Apply to declivity for the
duct hose.
6.2
Other possible reasons for out of order:
1.
The running of the unit after declined output of the mist for long hours, it may
cause the damage of the transistor of the PCB.
2.
If the unit is lay down or upside down and switch on the power, float switch will
operate to make running of the unit without water and it cause damage the
transistor of the PCB.
3.
If the water supply pace is slower than consumption pace of the water to make
mist, the water inlet solenoid valve will react ON-Off very often and it may cause
damage the valve. Minimum water pressure is o.3kgf/cm2.
4.
Big electric surge occurred by lightning strike may cause damage of PCB.
5.
If use megger tester to check PCB, it may cause damage of the PCB.
6.
If the water of the tank has grits, pebbles or iron powder etc, and operate for long
hours, it may cause the damage of the oscillator.
7.
If the some dirt or dust are caught at the valve, it may cause overflow.
8.
Higher voltage of the electric power supplied than specified voltage.
6.3 Countermeasures
<In case of declining of mist output at short after
the installation.>
1) If the water reservoir is contaminated with some
oil or adhesive materials used in plumbing, the
mist production will be declined. If it might be
so, switch off the power and drain the water.
And disassemble the mist outlet part and clean
the tank with neutral detergent and soft sponge.
And keep supply the water and drain it until the
bubble of the detergent will disappear to make
clean the tank.
2) Check the voltage of the electric power supply. If
it lowered, must be correct by power service
station.
<In case of declining of mist output after long hours running.>
1)
Check the surface of the oscillator. If it covered by some soil, clean up the surface
with soft cloth.
2)
If the surface is damaged or the plating is pealed off, replace it with a new
oscillator because the life has expired.
