Excessive water leak-
ing from the ear.
The water is not turned
on high enough. Turn the cold water on full in
order for the suction system to
work properly (but still within the
right temperature range).
Ear tip attachment
problem. Replace the ear tip with the tab
side pointing upwards.
Tubing connection
problem. Ensure that both tube fittings are
fit snugly into the chamber.
Incorrect technique. Check the Quick Reference
Guide to verify you are aiming
the water correctly.
Suction not adequate. Check suction by immersing tip
only into a graduated cup. Verify
the suction is at least 180 ml per
20 seconds. **
Difficulty removing
ear wax.
Water too cold Slowly increase water tempera-
ture until desired results occur.
Water flow inadequate With an ear tip attached, spray
water from the handle into a
graduated cylinder or measuring
cup for exactly 20 seconds. If
there was less than 100 mL or
more than 134mL of measured
water, replace the tip and repeat.
If the results are the same, con-
tact your Welch Allyn Technical
Service Department.
Patient has very hard
ear wax. Apply ear drops for about 5 - 10
minutes then retry. If unsuccess-
ful, have patient apply ear drops
overnight then retry.
Rotate tip within the ear canal (to
direct stream of water to differ-
ent areas rather than the same
spot).
Lack of a clean water
stream coming from
ear tip. Installation of ear tip
has caused a problem. Apply a new ear tip with the tab
side pointing upwards.
