6. Screw the bearing housing into the assembly
in the instrument.
7. Insert the bearing shaft assembly into the
bearing assembly. The shaft connector
attaches the motor shaft to the bearing shaft.
The bearing shaft is inserted through the
center of the bearing assembly. The bearing
shaft is secured in place with the small
bearing plate, which is screwed into the
bearing assembly with the one large thumb
screw. After screwing the shaft assembly into
the instrument, ensure that the four smaller
thumb screws are properly secured.
NOTE: Do not run the test bearing
without greasing it first.
The ball bearing located in the secondary
bearing housing on the motor side is greased
prior to shipment. Under normal operating
conditions, the ball bearing should be
replaced and greased every two years or as
needed. Refer to the Maintenance Procedure
for these instructions.
8. Fill the water bath distilled water. The pan in
the bath has markings to indicate the
minimum and maximum water level. Be sure
the drain valve (located on the side of the
instrument) is closed before adding water to
the bath. This water level must be maintained
to avoid the heater burning out.
NOTE: Always double check the water
level before beginning a test
9. Turn on the instrument and adjust the
temperature controller (Figure 5) to the
desired temperature as stated in the
standardized test method.
10. When the water has reached the specified
temperature, adjust the Flow Rate Control
Knob to the prescribed speed and verify
using the procedure outlined in Section 5.1.
11. To start a test, turn the spray switch to the
Start Test position to start the timer and the
motor.
NOTE: Make sure the cover is closed
before running a test. The test will not run if the
cover is open.
12. Proceed in accordance with the test
methods listed in Section 1.2.
13. Remove the water from the water bath by
placing a waste container under the drain
valve. Open the valve. Allow the water to fully
drain before closing. Be sure the drain valve
is closed before adding more water to the
bath. The drain valve is closed when the knob
is perpendicular to the spout.
6 Maintenance

6.1 Routine Maintenance
The K19201 Water Washout Tester requires
little routine maintenance to provide many years
of continuous service. However, over the course
of time, some instrument parts may need to be
replaced. When ordering replacement part(s),
please provide the model number, serial number,
and product shipment date of your equipment so
that we can ensure you will receive the proper
replacement part(s).
6.2 Bath Cleaning
•
To clean the instrument’s exterior, which
includes all painted surfaces and glass, either
a solution of soap and water or laboratory
grade detergent may be used.
•
Apply cleaner to clean wipe or cloth, not to
the instrument directly. Wipe surface clean.
•
Do Not clean bath exterior with organic
chemicals such as Acetone, Toluene,
Hexane, etc.
•
For more difficult cleaning of finished
surfaces, a dilute solution or isopropanol in
water may be used.
•
It is not recommended that more aggressive
solvents be used on painted surfaces since
paint color will tarnish or be stripped from the
instrument.
