Non Controller Operation
The pump can be controlled using an external, user sup-
plied, controller.
NOTE:
•
When using an external controller, Pump ON (Run)
Time should be set for no longer than 30 minutes.
•
In most cases, Pump OFF (Rest) Time should be
twice as long as Pump ON (Run) time. If alternative
ON / OFF times are required, contact Graco Cus-
tomer Service for assistance.
