Fluid rate is below or exceeds rated service flow of injector.

Has the new injector been stored for an extended period? If so, submerge the
injector in room temperature fluid for 24 hours so that the working parts can
reabsorb fluid and swell back to the proper size.
Operating pressure exceeds maximum limit. Install a pressure reducer valve.
