Maintenance for humidifier
1.Prior to performing maintenance
(1) Turn off main power switch and close water feed service valve before maintenance operation.
(2) High frequency vibration unit should be delicate, so do not make some scratch upon it with
driver.
(3) Do not feed power with high frequency vibration unit disconnected.
(4) Do not perform Mega Ω test and High Voltage test because electric components would be
caused trouble.
(5) Do not use except for genuine components.
(6) Use appropriate sized equipments. Too much or poor tightness would be caused trouble.

Compressor ON/OFF control
1) ON point:
With compressor delay timer is “0” and PV is continuously higher than
SV-0.3㷄 (ON point), compressor is forcibly turned on.
2) Compressor delay timer:
zCompressor would not turn on for 2min. since compressor
was turned off.
zCompressor delay timer initially set at “120” (2min.) when
compressor turns on.
zCompressor delay timer set at “120” (2min.) when the
power is supplied.
3) OFF point:
When PV goes lower than SV-3.0㷄 (OFF point), compressor is forcibly
turned off.
In case SV is higher than 45.0㷄 and Light Step (LS) is 0, 1, 2, 3:
zWhen PV-SV is equal or lower than -0.8㷄, compressor is forcibly turned off.
zWhen PV-SV is equal or higher than 1.5㷄, compressor is forcibly turned on.
Note) Compressor starts running with 2min. delay since the power was supplied.

Defrost control in evaporator
When unit starts defrosting, compressor is forcibly turned off and ratio of heater output is
100%.
Unit automatically finishes defrosting and retrieves normal operation or programmed
operation when temperature in DEF sensor is over than 10.0㷄.
Unit automatically finishes defrosting if it continues for 30min. or more.
7.
Control in evaporator for de-humidity
When setting RH is lower than 75%RH, evaporator for de-humidity is forcibly turned on.
When setting RH is higher than 75%RH, evaporator for de-humidity is forcibly turned off.
In condition that SV is lower than 40.0㷄, setting RH is 75%RH~85%RH and Light Step (LS)
is 0, 1, 2, 3:
zWhen displayed RH setting RH is equal or higher than -4%, evaporator for
de-humidity is forcibly turned off.
zWhen displayed RH setting RH is equal or lower than 4%, evaporator for
de-humidity is forcibly turned on.
In condition that SV is higher than 30.0㷄, setting RH is lower than 75%RH and Light Step
(LS) is 0, 1, 2, 3:
zWhen displayed RH is equal or lower than setting RH +15%, evaporator for
de-humidity is forcibly turned off.
zWhen displayed RH is equal or higher than setting RH +18%, evaporator for
de-humidity is forcibly turned on.
8
Defrost control in evaporator for de-humidity
In evaporator for de-humidity turns on, automatic defrosting starts at both AM3:00 and
PM 3:00. Once defrost begins, DEF relay turns on (heater side) from off (valve side).
When temperature in de-humidity DEF sensor is over than 15.0㷄, defrosting finishes
automatically with DEF relay turned off (valve side).

(Ex) In RH is 55%RH, Analog RH is 495 and analog output voltage
is 53mV, input “505” in column of Analog RH to get analog output
voltage to 55mV
