HEAD – DIS-ASSEMBLING & ASSEMBLING – All Models
Step 4. Removing Head Seal
1. Using a small screw driver or similar tool
remove the o-ring. However, do not
damage the sealing surface in any way
as it may lead to leakage.
Removing Seals
It is recommended that all seals be

It is recommended that on 80E30 vessels,
the snap ring be replaced each time head
is assembled.
Component Cleaning and examination
Step 1. Wash Components
1. Wash all components in fresh water.
2. Blow components dry with compressed
air, if available. Otherwise wipe dry with
a dry, lint-free cloth.

Step 2 Initial Component Inspection
2. Examine all components for any damage
that could affect structural strength or
sealing properties.
3. Replace any parts considered to be
structurally unacceptable.
Feed and Concentrate ports and attachments
to the shell must be carefully inspected to
ensure
materials are sound and tight. Any questions
or evidence of deterioration of these areas
should be referred to Pentair Engineers.
