Flush the Equipment

To avoid fire and explosion, always ground equipment
and waste container. To avoid static sparking and
injury from splashing, always flush at the lowest pos-
sible pressure.
Failure to flush prior to material beginning to cure in
the system will result in damage to system and may
require replacement of all parts in contact with the
material.
System and hoses must be flushed with water. Flush-
ing equipment with non-water flushing agents (sol-
vents) may cause damage to system and hoses.
The pressure relief ball valve (J) must be flushed to
prevent material hardening. Hardening may cause
damage to system.
Flush before changing colors, before fluid can dry in
the equipment, at the end of the day, before storing,
and before repairing equipment.
Flush at the lowest pressure possible. Check
connectors for leaks and tighten as necessary.
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
material flushing agent between flushes and
replacing it with clean material flushing agent.
For some mortars, it is recommended to flush every
3-5 kits. Others can run continuously without
flushing. See material manufacturer
recommendation.
