Head Disassembly and Inspection
Step 1 Remove the Head O-ring
– Use a non-metallic, rounded tool to start the o-ring
out of the o-ring groove. Once a small portion of the o-ring has been lifted out of the
groove, use your hand to work the remainder of the o-ring out of the groove. Damaged
or cut o-rings must be replaced during re-installation of the head.
Step 2 Remove Adapter
– Grasp the adapter slowly pull from the bearing
plate/permeate port. A slight rotating motion may ease the removal of the adapter.
There is a set of double o-rings on the inside diameter of the permeate port that must be
inspected for damage once the adapter is removed. Damaged o-rings must be
replaced before re-installation.
Step 3 Remove Bearing Plate
– Use a wrench to remove the permeate port Locknut.
The locknut is reveres threaded (or left hand threaded) and must be turned clockwise to
be removed and counter clockwise to be installed. After removing the locknut, the
bearing plate and sealing plate can be separated.
Step 4 Clean All Components
– All components should be cleaned with a mild soap
