CANISTER – DISASSEMBLY/ASSEMBLY
• Remove the counterlungs and hoses by unscrewing the hose lock rings,
counterclockwise. Clean and inspect the sealing face for each end cap
seal, hose ends, and counterlung ports.
• Disconnect the LCV balance cap and tube from the exhale counterlung
to the Canister at the counterlung (Fig. 2.20). This is a 1/2 turn (counter-
clockwise) unlock. Release the locking tabs, as shown (Fig. 2.21).
• Inspect the LCV counterlung mushroom valve and cap sealing ring for
damage (Fig. 2.22). Replace/re-lubricate as required.
• In normal diving operations the canister should be flushed with fresh
water, rinsed with sanitizing solution, and wiped clean.
STANDARD ABSORBENT SCRUBBER PACK -
DISASSEMBLY/ASSEMBLY
! WARNING: Filling a scrubber improperly could lead to a hypercap-
nia incident and possible death.
• Disassemble and discard the absorbent material as per local regulations.
Wash the scrubber pack in warm soapy water to remove absorbent debris.
Sanitize as required.
• Inspect the scrubber pack for damage, especially around the Quad ring
sealing surface.
• Inspect the quad ring seal before every dive. It must be replaced at the
first sign of wear or damage.
!
DANGER: The quad ring seal is extremely important, and it should
be regularly cleaned and inspected. It is vital in preventing CO
2
bypass. Additionally, it must be replaced at the first sign of wear
or damage.
!
DANGER: The quad-ring is not a standard O-ring. It must not be
replaced with anything else.
• Inspect the cannister and lid mesh for damage.
• Place a Dust Filter inside at the base of the scrubber canister (Fig. 2.23).
It should lay smoothly against the metal screen bottom with the tabs along
the radial edge folded upwards. Ensure that the tabs lay smoothly against
the inner walls of the scrubber canister.
!
NOTE: The Dust Filter must be replaced if it begins to show signs
of deterioration or becomes torn.
