D. Differential Pressure Gauge (DPG) - Grades B, C, D, E, F
On standard units, a gauge and installation kit are
shipped separately packaged for field installation. Refer
to diagram for proper installation. Gauge may be
installed on filter housing or on a nearby wall using the
wall mounting bracket supplied.
NOTES:
1) Make certain o-rings are in place on the bottom of
the gauge body.
2) Connect the low pressure transmission bolt (bolt
next to RED band on gauge) to the gauge port at
the filter outlet (down-stream side of filter).
3) Connect the high pressure transmission bolt (bolt
next to GREEN band on gauge) to the gauge port at
the filter inlet (upstream side of filter).
4) Torque bolts to 25 +/- 5 inch oz. A flathead screwdriver
with a 3/8” (1 cm) minimum blade width can be used
to assemble/diassemble the gauge. Small blade widths
will damage the bolt heads.
