CyberAiR DX Floor Mounted IOM Manual
NOTE
Decrease the humidity set point below
ambient humidity to allow the cylinder to cool
down before removing the cylinder.
1. Turn the A/C unit Off by pressing (and holding)
the Enter key on the
E²
controller.
2. Turn off the water supply to the humidifier.
3. Turn the main power disconnect switch(es) Off
and open the doors of the A/C unit.
4. Turn the fan motor starter protectors (Q01,
Q02, Q03,...) to the Off position.
5. Fashion a jumper wire and install it across the
terminals on the airflow switch (F40).
6. Using a pair of vise grips, turn the shaft of the
main power switch to the On position to
provide power for the humidifier drain
solenoid.
7. Drain the cylinder by pushing the “On-Off-
Drain” switch to the Drain position.
8. When drained, push the “On-Off-Drain” switch to
the Off position.
9. Turn the main power disconnect switch Off to
disconnect power from the humidifier and
remove the jumper from the airflow switch.
10. The power wires to the cylinder are attached
by cylinder plugs to the electrode pins on top
of the cylinder. Pull these plugs vertically off
the pins.
CAUTION
The cylinder and steam hose may be hot and
burns may result.
11. Loosen the steam hose clamp(s) and pull the
steam hose off vertically.
12. Using a flat head screwdriver, press the tab on
the cable tie to release it. Lift the cylinder
straight up to disengage it from the humidifier.
13. Place the new cylinder on the side mounting
slots within the unit, ensuring the cylinder
mounting stubs are seated properly.
14. Replace the cylinder plugs on the pins,
ensuring the white sensor plug goes on the
single pin, which is offset from the others.
15. Ensure the plugs are secured on the pins. If the
plugs are loose, they may be temporarily
squeezed together, however, the plugs must be
replaced since a loose plug could generate
enough heat to melt and destroy the plug.
16. Replace the steam hose and tighten the clamp(s).
17. Push the “On-Off-Drain” switch to the On
position.
18. Turn the fan motor starter protectors (Q01,
Q02, Q03,...) to the On position.
19. Close the A/C unit doors and turn the main
power disconnect switch(es) to the On position.
20. Turn on the water supply to the humidifier.
21. Turn the A/C unit On by pressing the Enter key
on the
E²
controller.
22. Adjust the humidity to the desired set point.
If the humidifier is to be shut down for an extended
period, always drain the cylinder first. Follow the
above steps (1 through 8) ensuring the “On-Off-Drain”
switch is in the Off position. Failure to do this will
drastically shorten the cylinder life.
4.3.4.5 Air Filter Replacement
The air filters are accessed from inside the cabinet.
To change the filters, open the front doors of the
cabinet. For upflow units, the filters are located
behind the air intake grilles. For downflow units, the
filters are located at the top where the label “FILTER
ACCESS” appears. Remove the old filters from the
trays. Insert the new filter(s) ensuring the directional
airflow arrows on the filters are correct.
