C. Piping
1. Before installing, blow out pipe line to remove scale
and other foreign matter.
2. This unit has DRYSEAL pipe threads; use pipe com-
pound or tape sparingly to male threads only.
3. Mounting (Grades 11,9,7,5,3) - mount so that inlet
and outlet connections are horizontal (filter bowl
vertical) to ensure proper liquid drainage.
4. Flow Direction - install so that the air flow is in the
direction of arrows on the filter head.
NOTE:
Grade 6 flows from outside to inside the
element. All other grades flow from inside to out-
side the element. Observe flow arrows on cap.
5. Direct filter-to-filter (modular) connection - Filter
heads may be joined without using a pipe nipple
a. Bayonet type heads - Use two (2) modular con-
nectors, o-ring, and four (4) socket head cap
screws (sold as kit)
Remove black plastic top cap, apply generous
amount of lubricant to o-ring, install o-ring in
groove, and insert connectors. Screw connec-
tors to head using socket head cap screws.
