Filter Disassembly / Assembly - AquaTools AT8695 Manual De Usuario

D. If the ring was already locked, remove it and the fil-
ter lid assembly. Inspect and clean the O-ring and all
sealing surfaces. Relubricate the O-ring, if necessary.
NOTICE: Lubricate the O-ring sealing area inside the
upper tank lip with silicone grease, as other lubricants
may cause the ring to swell. DO NOT lubricate the Posi-
Ring™ or the threads on tank shell as this may collect
grit and make removal difficult.
After the filter is operating, record the filter pressure
gauge reading in the owner's manual for future use.
FILTER DISASSEMBLY/

Figure 4 – Depress safety latch to unscrew the
Posi-Ring™.
b. Hold the latch in the release position and rotate the
ring COUNTERCLOCKWISE to remove it. If the ring
is difficult to turn, tap it gently with a rubber mallet
to overcome initial resistance.
5. Inspect the O-ring for cuts, cracking, deformation or
signs of wear; replace if necessary.
NOTICE: Do not remove the O-ring unless you need
to replace it. To remove it, hook it out of its groove with
a stiff curved piece of wire inserted through the small

groove. Replace damaged parts as necessary.
2. Install the filter cartridge in the tank. Push down firmly

NOTICE: Lubricate the O-ring sealing area inside the
upper tank lip with silicone base grease, as other lu-
bricants may cause the ring to swell. DO NOT lubri-
cate the Posi-Ring™ or the threads on the tank shell
as this may collect grit and make removal difficult.
3. Install the O-ring in the tank lid assembly O-ring
groove. Be sure that the O-ring is clean and not
twisted.
