These Pro Series models have different printed power labels and separate manuals.
Match the model before choosing a document
Identifier: Pro Series 615 / 628. This guide compares a family or related models. Use the exact configuration on your label.
Models covered: 615, 628. They are separate configurations; compare the applicable facts and documents below.
The 615 cover prints 1/2 HP; the 628 cover prints 3/4 HP. Use the model number, not only the Pro Series name, to choose a manual.
The 615 manual describes the serial label on the side panel; the 628 manual describes it on top. Retain that information when contacting Guardian, without publishing a personal serial number.
628FCA has separate audio-console documentation. Its suffix identifies a distinct record rather than another spelling of 628.
