Reverse Prime injection System
Reverse Prime is not a standard feature on the peristaltic injection pump, but may
be added at any time. Contact your local teeJet technologies distributor to order
the Reverse Prime feature (Part # 54-02015).
Reverse Prime works similarly to the priming procedure except that the pump runs
backwards and moves chemical from the injection point back to the supply tank
to preserve as much chemical as possible.
The priming feature appears as an
option only if “Injection” was selected as the “drive Type” during Channel
setup.

this page is used to monitor pump priming progress during priming. the
