1. Press Air Temperature key. Temperature must be at control set point (120

C).
If customer assigned values replace factory values: To check control setting

When finished, press the
Clear
key to
return to normal operating mode.
Note:
Increase in Air Temperature will cause the oil viscosity to decrease
resulting in an increase in mist production.
2. Perform oil consumption test on oil mist console. Adjust oil consumption to .65
cu. in oil/Hour/SCFM air using mist head adjustments. See troubleshooting
instructions for LOW MIST DENSITY above for adjustment locations.
3. Once optimal oil consumption is achieved, refer to instructions for Oil Mist
Monitor. Select sensitivity adjustment to obtain a mist density reading of near
50%.

key. Normal mist pressure is 20 In H2O / 50mBar.
Verify that the low mist pressure alarm setting. Note whether customer assigned
values have been programmed to the replace the factory values. Press the key

to read the low alarm setting. Press the
Clear
key to
return to normal operating mode.
2. If the mist pressure is near the Low Alarm Setting (10in H2O – 25mBar) check
the oil mist header systems for broken mist lines or pipes and IVT oil mist
generator for leaks.
3. Verify that the regulated air pressure has not been changed from the original
setting established at commissioning. When adjustments are made, the EVENT
LOG records the event. See the section titled
Event Log
under
LOCAL ALARMS,
INDICATORS AND READOUT
in the Installation and Operating Manual for
instruction on how to access the event log. If it is determined that the regulated
air pressure has been changed, and that the Low Mist Pressure alarm is due the
change in regulated air pressure correct the setting. Adjust the air regulator to
achieve 20in H2O oil mist pressure, ensuring not to exceed 65PSI – 4.48Bar
Regulated Air Pressure. If regulated pressure does not increase with adjustments
to air regulator. The air regulator is defective and should be replaced (CFH-RS
part no. 77700501).
4. If adequate mist pressure cannot be achieved with a functional air regulator, the
capacity of the mist head has been exceeded. This situation occurs when the
mist system is expanded to service additional equipment and bearings. If the oil
mist system has been expanded, verify that the mist head vortex size is adequate
for the service load. If the mist generating capacity has been exceeded, the
vortex cartridge will need to be replaced to next larger size. See table in IVT
Operating Instruction Manual section CONTROLLING THE MIST for part
numbers, mist head sizes and replacement instructions.
