B. Mounting
1. Wall mounting brackets - Mount bracket to filter
head:
(1) remove four (4) screws holding black plastic top
cap to filter head
(2) place bracket on head over plastic cap
(3) install screws supplied with bracket.
2. Differential Pressure Gauge Mounting to Filter head
(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 the RED band on gauge) to the gauge
port at the filter outlet (downstream 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 the filter).
(4) use a coin or a flat head screwdriver to tighten/
loosen bolts. The tip width of the screwdriver
should be at least 3/8" inch (9.5 mm). Torque
bolts to 25 +/-5 inch oz.
DO NOT OVER TIGHTEN.
