(65PSI –
4.48BAR) 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 20in 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.
77700501).
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 whether
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.
1. 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
IVT Operating Instruction Manual section CONTROLLING THE MIST for part
numbers, mist head sizes and replacement instructions.
