* To properly test suction, follow the steps below:
The water splash is
making a mess or
splashing onto adja-
cent electrical units. Excess water pressure
from the water line. Ensure that the chamber aerator
is attached to the bottom of the
chamber.
The water pressure
from the ear tip
seems too high or
too low.
Installation of ear tip
has caused a problem. Apply a new ear tip with the tab
side pointing upwards.
There is leakage from
the chamber aerator
and/or adapter Tighten the aerator and/or
adapter with a pair of pliers.
The return water exit
port is clogged on the
bottom of the cham-
ber. Remove the chamber from the
faucet and dislodge any foreign
materials from the exit port. Pro-
ceed with the normal cleaning
procedure.
There is an internal
malfunction. Check
water pressure from
the sink. 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 the flow is still above 125
ml / 20 seconds, either add regu-
lation to the faucet or move to a
faucet with adquate water pres-
sure and flow. Otherwise, con-
tact your Welch Allyn Technical
Service Department.
