1. Verify that the regulated air pressure has not been changed from the original
setting established at commissioning.
IMPORTANT: CARE MUST BE TAKEN WHEN ADJUSTMENTS TO THE
REGULATED AIR PRESSURE SETTING IS MADE. MAKE CERTAIN THAT ALL
RECLASSIFIER FITTINGS ARE PROPERLY INSTALLED. CHECK ALL
DISTRIBUTION HEADER AND BRANCH PIPING FOR BREAKS AND LEAKS
WHERE MIST FLOW CAN ESCAPE. CHANGING THE REGULATED AIR
PRESSURE CHANGES THE TOTAL MIST VOLUME (SCFM) BEING
PRODUCED AND DISTRIBUTED TO THE EQUIPMENT BEING SERVICED.
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 no
occurrence of a Low Mist Pressure is recorded, then the setting may be corrected.
Increase the regulated air pressure to achieve 20 inches H2O oil mist pressure. If
regulated pressure does not change with adjustments to air regulator. The air
regulator is defective and should be replaced (CFH RS part no. 77780127).
If a Low Mist Pressure alarm is recorded in the Event Log, then it possible that
adjustments to the regulated air pressure setting were made to correct the mist
pressure alarm. Correct the source of the low mist pressure alarm.
2. Press
Mist Pres
key. If pressure is near Low Alarm Setting (10in H2O – 25mBar)
check the oil mist header systems for broken mist lines or pipes.
Note:
Check to see whether the customer assigned values have been
programmed to the replace the factory values. To check low alarm setting press
key combination
Set
,
Mist Pres.
Press the
Clear
key to return to normal operating
mode.
3. If adequate regulated air pressure adjustment cannot be achieved to maintain the
normal operating mist pressure, the system oil mist flow requirement may be
greater than the operating capacity of the mist head. This situation can occur when
the mist system has been expanded and equipment is added to the system. If the
oil mist system has been expanded, verify that the mist head vortex size is correct
for the service load. If the mist generating capacity is under capacity, the vortex
cartridge will need to be replaced to a larger size See table in

sizes and replacement instructions.
