9. Circulate clean water:
a. Fill the system hopper with clean water.
b. Use a scrub brush to scrub the walls of the
hopper.
c. Turn the motor power switch (S) to ON to begin
circulating water.
d. While pumping, open the fluid drain/purge
valve. Allow the water to flush out any material
to prevent material hardening in the valve. Once
the water appears clean, close the fluid
drain/purge valve.
e. Turn the motor power switch (S) to OFF.
f. Place hose outlet in a waste container.
g. Turn the motor power switch (S) to ON to
dispense into a waste container.
h. Dispense into a waste container until hopper is
almost empty then turn the motor power switch
(S) to OFF.
i. Repeat this entire “Circulate clean water” step
one more time to ensure system is thoroughly
flushed.
10. Remove the remaining material with a hose
clean-out ball. See
Replacement Parts and
Accessories
on page 30 for a list of available
clean-out balls and appropriate hose sizes to use
with them.
a. Place the hose outlet in the waste container.
b. Remove the hose inlet from the pump outlet and
place a hose clean-out ball within the hose inlet.
The ball must be wetted down before inserting.
c. Reattach the hose to the pump outlet and turn
the motor power switch (S) to ON to resume
flushing the hose.
d. The hose clean-out ball will be pushed out of
the hose after several minutes. Once the ball is
pushed through the hose, turn the motor power
switch (S) to OFF and repeat the entire process
listed in step 10 one time to ensure the system
is thoroughly flushed.
11. After performing the previous step at least twice,
drain remaining water from system:
a. Place a drain pan beneath pump lower inlet
connection.
b. Detach pump from hopper.
c. Use a screwdriver to lift the pump lower inlet
ball. This will drain the remaining material from
the pump lower. When the pump stops draining,
release the pump lower inlet ball.
d. Reattach pump to hopper.
e. Starting at the pump, raise the hose bundle
above your head and slowly move towards the
applicator. As you move towards the hose
outlet, the remaining fluid in the hose will drain
from the hose into the bucket.
12. Dispose of all waste material in accordance with
local codes and regulations. See manufacturer’s
SDS for additional information.
NOTICE
Material left on the throat seal can dry out and damage
the seal. Always stop the pump at the bottom of the
stroke to avoid damage to the throat seal.
