Description
The Pentair Fan Guard (473786Z) is the OEM replacement fan guard for the UltraTemp ETi heat pump series. This is the protective grille assembly that mounts over the fan discharge on the top of the unit.
IMPORTANT: LICENSED PROFESSIONAL INSTALLATION REQUIRED
Heat pump components must be serviced by a licensed pool professional or qualified HVAC technician. Do not attempt to service high-voltage components without proper certification.
The fan guard shields the rotating fan blade from contact while allowing unrestricted airflow through the heat pump’s discharge path. A damaged or missing guard exposes the fan assembly to debris ingestion and presents a safety hazard. Replacing a cracked, corroded, or deformed guard restores both the protective function and the structural integrity of the unit’s top panel assembly. Match the part number on your existing guard before ordering confirm your unit is the UltraTemp 220 ETi model.

Pro Tip
Before ordering, visually inspect the mounting points on your existing guard. Fan guards on heat pumps are exposed to UV, poolside chemicals, and seasonal temperature extremes if the grille is warped or the mounting tabs are cracked, replace it promptly. A loose or improperly seated guard can contact the fan blade during operation, causing vibration and accelerated bearing wear.
