1. Check the supply air shut off valve for main unit located at the operator panel,
ensure the valve is in the full open position.
6. Verify that the air supply source has sufficient capacity to service the oil mist
demand. Check the supply air piping system to ensure that all block valves are
fully opened and that piping is sufficiently sized to eliminate unacceptable
pressure drop at operating conditions.
2. 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 NOT PLUGGED AND THAT ALL
DISTRIBUTION HEADER AND BRANCH PIPING IS FREE FROM
OBSTRUCTIONS AND TRAPS. 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 High 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 High 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 high mist pressure alarm.
Note:
Oil mist generating head will not produce oil mist with a regulated air
pressure below 10PSI - .69Bar
3.
4. If installed, confirm that all collection containers have been properly drained and
checked. Also, confirm that all Automatic Drain Leg reservoirs installed in oil mist
systems are draining correctly.
Note:
Overfilled collection containers or drain leg reservoirs will produce a higher
oil mist pressures condition.
5. If adequate regulated air pressure adjustment cannot be achieved to maintain the
normal operating mist pressure, the system oil mist flow requirement may be less
than the minimum operating capacity of the mist head. This situation occurs
when the mist system is reduced and equipment is removed from the system. If
the oil mist system has been down scaled, verify that the mist head vortex size is
correct for the service load. If the mist generating capacity is over capacity, the
vortex cartridge will need to be replaced to next smaller size. See table in IVT
Operating Instruction Manual section CONTROLLING THE MIST for part
numbers, mist head sizes and replacement instructions.
