KT Electrodes Humidifiers
To resume the procedure; turn clockwise the trimmers to increase the out-put of the humidistat,
or, turn the trimmers counter clockwise to decrease the output of the humidistat. In particular, P2
increases the output, P4 decreases the output.
P3:
This trimmer converts the steam production in a voltage to be compared with the demand of the
humidistat.
It's calibrated in the factory. Do not touch!!
P5:
This trimmer adjusts the timing between the water supplies.
The water enters in the boiler in small quantity between large time intervals to allow the
electronic card to control the water quality, ...
P6:
This trimmer is important only when the humidistat output is not usual. Few kind of humidistats
don't give "0 Volt" when they are meant to stop the steam production (humidistat asks
humidification when the output is between 3 and 10 V, and dehumidification when the output is
between 0 and 3 V).
In this case, set the humidistat to the minimum (20% UR) and turn the trimmer P6 clockwise until
the humidifier stops steam production and then set the humidistat to the maximum (90%) verifying
that the humidifier lights the led no. 2.
WARNING: FOR ALL OTHER HUMIDISTAT, leave the trimmer P6 fully counter-clockwise!!!

6. Start up

Before turn ON the humidifier check following points:
- the installation of the humidifier is solid and vertical
- the earth terminal of the metallic parts is correctly connected
- the water supply is cleaned, and at a right pressure
- the drain plumbing is well sized and not siphoned
Disconnect the humidistat, connect the screws 1 & 2 of the humidifier electronic card to simulate
the humidistat "on", and connect the screw 4 & 5 to simulate the airflow "on".
Switch on the power supply and the cover micro switch: LEDS 1 and 2 should be on. LED 4 lights up
and the water starts to fill the boiler washing the hydraulic system completely. If the process
completes correctly LED 6 turns ON for few seconds. Water fills completely the siphon (7) and LED
4 turns OFF. At that time, LED 6 turns OFF and water starts entering in the boiler for steam
production. Input solenoids stops when the production is at its minimum (0.5 A), then the solenoid
