Picture 1 – Detail picture of head removal tools.
Picture 2 – Thread the center piece into the permeate port of the head assembly, to
hand tight. Do not over tighten the center piece.
Picture 3 – Position nut, bearing rod, and bearing block as shown. Turn bearing rod
clockwise. The head will move with the bearing rod as it moves toward the end of the
vessel. You will be able to remove the head once it has cleared the retaining groove
area of the vessel.
Alternative Head Removal
– It is possible to remove the head assembly without the
ROPV head removal tools. A 1” NPT Male threaded piece of PVC (or similar material)
pipe should be threaded into the head permeate port to hand tightness. Pull the pipe
outward to remove the head. If the vessel has been in operation for an extended time,
a slight rocking motion or forceful tug may be required to break the head seal bond.
Also, a handle at the end of the pipe will ease head removal – forming a T with the pipe
that threads into the permeate port.
