3.4 Attaching accessories to the endoscope
The air/water valve and the suction valve do not require
lubrication. Lubricants can cause swelling of the valves’
seals, which will impair valve function.
Attaching the suction valve
1.
Align the two metal ridges on the underside of the suction valve with the two
holes in the suction cylinder.
2. Attach the suction valve to the suction cylinder of the endoscope (see
Figures 3.15 and 3.16). Confirm that the valve fits properly without any
bulging of the skirt. Also confirm that the valve cannot be rotated.
