3. Differential Pressure (
∆
P) Gauge
All accessories and a detailed instruction sheet are packed
with your gauge.
1. Mount the gauge in a location f ree fro m excessive
vibration, where the temperature does not exceed 140°F
(60°C). Avoid direct sunlight.
2. Co nnect the gauge using 1/4" plastic tubing a nd
compression fittings or 1/4" copper tubing and fittings.
3. Place a loop in the high pre s s u re line from the dirty air
housing to keep dust out of the gauge line (see diagram
below; also note the two additional, optional techniques
shown).
4. Adjust the differential pressure gauge to zero reading when
there is no flow through the separator.
Loop in tubing (dirty air side) should be at least 12” higher than clean
air connection to keep dust out of gauge line.
Small in-line filter (not provided) may also be used at inlet to dirty
side tubing.
Optional setup with 3-way valves which bleed air continuously except
when reading gauge; airflow minimizes dust plugging.
4. Discharge Valve
If an optional rotary feeder or other discharge valve has been
supplied, it should be bolted to the discharge flange of the
separator according to manufacturer’s instructions.
5. Electrical
CAUTION: All wiring and electrical adjustments or
installations must be done by a qualified electrician in
a c c o rdance with the National Electrical Code and local
codes.
NOTE: In addition to Spencer’s standard NEMA 4 enclosure
for the sequence timer and solenoids, optional NEMA 7/9
enclosures are also available.
Connect 115 volt, single phase, 60 Hz, 10 amperes power
supply to sequence timer terminals marked Line L1 and L2.
In grounded systems, connect neutral of line to L2.
I n t e rconnecting wiring between the sequence timer and
solenoid valves is installed at the factory. In operation, the
sequence timer signal starts at Solenoid 1, then activates
Solenoid 2 and continues in sequence to the last selected
solenoid, then recycles. Tu rning the sequence timer switch
OFF, then ON, resets the sequence; the cycle begins again at
Solenoid 1.
Sequence Timer adjustments are:
Pulse Time, duration of each air pulse, is factory preset
at 100 milliseconds, adjustable from 50 to 500 ms via
potentiometer (see diagram above).
Step Time, interval between pulses, is factory preset at
a p p roximately 20 seconds, adjustable from 8.5 to 180
seconds via potentiometer (see diagram above).
