an attached piece of tubing or by any other appropriate means.
2. Fill the valve chamber with the disinfectant through the upper hose
piece.
3. Leave to act for the prescribed time.
4. Empty the valve chamber by unplugging the lower hose piece while
holding a recipient under the valve allowing the disinfectant to ow
out.
5. Connect a exible bottle with cleaned water to the upper hose piece
and rinse through the upper hose piece.
6. Leave the squeezed bottle connected to the upper hose piece and
clamp the hose to avoid contamination from air being sucked in
through the valve.
