General

Identify Your Hunter Product Family

Start from the label or model family before applying model-specific instructions.

Brand path

Research standard

Brand claims need current source support.

Manufacturer documentation

Model behavior, terminals, compatibility, settings, and service steps should use current official references.

No guessed compatibility

Replacement parts and model-specific instructions should not be inferred from appearance alone.

Generic vs model-specific

If the brand does not change the diagnosis, link back to the generic topic guide instead of duplicating it.
