Keep Components A and B Separate
Cross-contamination can result in cured material in
fluid lines which could damage equipment or cause
serious injury if injected or splashed on skin or in
eyes. To prevent cross-contamination of the equip-
ment's wetted parts, never interchange component
A and component B parts.
g. Use supply systems to load the system.
h. To prime the pump, cycle the pump a few times
or until air-free fluid dispenses. See Home
Screen on page 32 for instructions on priming
the pump through the ADM.
To prevent serious injury from splashing, dispense
fluids at a low pressure.

pense valve until both fluids flow freely from the
nose piece without any air.
