Flush
•
Flush if the materials in the system are about to
reach their cure time.
•
Flush any time the flow rate starts to decrease as
this is a sign that material is starting to thicken and
cure.
•
Always flush the system at least twice, draining all
water between flushes then replacing with clean
water.
•
Flush using water only.
1. Relieve pressure (see
on page 18).
2. Remove applicator tip and retainer.
3. Place applicator outlet in a waste container. The
waste container must be large enough to hold all
dispensed material.
4. Turn motor power switch (S) on.
5. Turn adjustment knob (H) clockwise slowly to
increase pressure, until a steady stream flows from
applicator.
6. When the material level in the hopper is within a few
inches of the material inlet at the bottom:
a. Scrape the material down the sides of the
hopper.
b. Fill the hopper with water as the material runs
out and continue dispensing.
7. Keep the hopper filled with water while dispensing.
NOTE:
Be prepared to decrease the flow
adjustment knob (H) when the material exiting the
hose changes to water.
8. When water begins to exit the applicator outlet, turn
the motor power switch (S) to OFF to stop
dispensing.
9. Place applicator in the system hopper with the outlet
pointing down to enable fluid circulation.
10. 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.
NOTICE
Failure to flush prior to material curing in the system will
result in damage to system and may require
replacement of all system parts in contact with the
material.
NOTICE
If the fluid/drain purge valve has been used to relieve
pressure, the valve must be flushed to prevent material
hardening in fluid/drain purge valve. If that is not
sufficient, remove, disassemble, and clean the valve
then reinstall.
