2. Remove the diptube using one of the diptube
removal tools (part number NA-13), Figure 15.
3. This step does not apply to a 20-liter canister with
NC-W2 closure. In this configuration, the diptube
was removed by the end user along with the
dispense connector.
• If using the NA-13 tool, insert the tool into
the coupler and tilt at an angle to the side.
Lift straight up to extract the diptube from
the retainer.

4. (200-liter canister only) Remove the fitment adapter
from inside the canister neck, Figure 4, page 6. Use
either of these methods:
• Manual: Pull up on the edges of the adapter to
disengage the O-ring or use the liner removal tool.
• Liner removal tool (part number DA-04): Place the
bottom opening of the tool over the top of the
adapter and turn clockwise until it stops. While
holding the liner with one hand, pull up on the
liner removal tool with the other hand until the
O-ring is disengaged from the liner fitment.
5. Drain any residual chemical from the canister
before removing the liner from the canister.
6. Remove the liner from the canister. The liner
should be fully collapsed before performing this
step, Figure 16.
• Place the liner removal tool over the top of
the fitment.
• Rotate the liner removal tool 90° until it stops.
• With one hand, pull up on the liner removal tool
while the other hand guides the liner out of the
canister. Use a gentle, side-to-side motion to
prevent tearing of the liner during removal.
• When the liner is completely removed from the
canister, disconnect the liner removal tool from
the retainer.
• Install the appropriate liner disposal plug (part
number NA-07 for 4- to 40-liter canisters) in
the liner fitment. Make sure the disposal plug
is firmly seated.
• Consolidate used liners, then dispose of the liners
in an appropriate manner based on the chemical
in the liner.
WARNING: Used liners may contain small amounts
of chemical vapor. Proper ventilation and safety
equipment are required for liner removal. Dispose
of used liners in accordance with local laws and
regulations for contaminated waste.
IMPORTANT: If the liner tears during removal, and
chemical spills inside the canister, the canister
interior must be thoroughly cleaned before being
recycled or reused.
