WET TEST, STAGE II
After determining the absence of any major leak in Stage I testing, PEN-
TAX Endoscopes may be immersed to test for loss of integrity in their
watertight construction.
1)
With the Leak Tester securely attached to the scope and the
scope pressurized with the gauge indicator in the GREEN zone,
and the soaking cap securely attached over the electrical con-
tacts on the umbilical cable of the scope, the entire scope may
be immersed in clean water.
2)
Observe the instrument carefully while fully angulating the dis-
tal tip of the scope. A few bubbles may occur initially from the
recessed areas of the scope. This is normal. If a continuous
stream of bubbles is observed from the same spot, a leak is
indicated. Immediately remove the scope from the water. DO
NOT use the scope.
3)
After removing the scope from water, release the air pressure
within the scope by pushing the “IN” pressure “RELEASE”
trigger on the handle of the Leak Tester. After the gauge indi-
cates ‘zero’, disconnect the Leak Tester from the scope.
4)
If leakage was discovered in step (2), thoroughly dry the instru-
ment and contact your PENTAX Service Center.
5)
If no leakage was discovered in step (2), you may proceed with
cleaning and disinfection/sterilization of the scope as described
in the Operating Manual for the specific PENTAX scope
involved.
NOTE:
Only the Leak Tester connector and a small portion of its tubing
should be immersed. NEVER immerse the entire Leak Tester or
bulb/gauge areas.
NOTE:
NEVER
connect or disconnect the Leak Tester under water. This
will cause leakage of water into the scope and Leak Tester.
