11. In 24 hours, take an oil sample. Observe the color
and test for acidity. If the oil is dirty or acidic,
replace the suction line filter-drier.
12. In 2 weeks, examine oil to determine if another
suction line filter-drier change is necessary.
4.3.4.4 Humidifier Cylinder Replacement
After an extended period of operation a red light will
illuminate on the humidifier cabinet, indicating that the
cylinder is completely used and a replacement
cylinder must be installed. The cylinder is disposable
and cylinder life is dependent on water supply condi-
tions and humidifier usage. The following procedures
are to be followed when replacing the cylinder.
CAUTION
Failure to replace cylinder at the end of cylinder
life may result in humidifier damage.
NOTE
Decrease the low humidity setpoint below am-
bient humidity to allow the cylinder to cool down
before removing the cylinder.
1. Turn off the water supply to the humidifier.
2. Drain the cylinder by pushing the AUTO/ON-OFF-
DRAIN switch to the DRAIN position.
3. When drained, push the AUTO/ON-OFF-DRAIN
switch to the OFF position.
4. Disconnect power to the humidifier at the main
power disconnect switch.
5. 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.
6. Loosen the steam hose clamp(s) and pull the
steam hose off vertically.
7. Lift the cylinder straight up to disengage it from
the humidifier.
8. Place the new cylinder on the side mounting slots
within the unit; ensuring the cylinder mounting
stubs are seated properly.
9. Replace the cylinder plugs on the pins, ensuring
the white sensor plug goes on the single pin which
is offset from the others.
10. Ensure the plugs are secured on the pins. If the
fitting 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.
11. Replace the steam hose and tighten the clamp(s).
12. Connect main power to the humidifier at the main
power disconnect switch.
13. Push the AUTO/ON-OFF-DRAIN switch to the
AUTO/ON position.
14. Turn on the water supply to the humidifier.
If the humidifier is to be shut down for an extended
period, always drain the cylinder first. Follow the
above steps 1 through 4 ensuring the AUTO/ON-OFF-
DRAIN switch is in the OFF position. Failure to do this
will drastically shorten the cylinder life.
4.3.4.5 Filter Replacement
The filter(s) are located inside the cabinet and are
accessed through the front, hinged access door. Open
the access door and remove the old filter(s). Insert the
new filter(s), ensuring the directional airflow arrows on
the filter(s) are correct then close the access door.
