The Wacker Neuson Inline GFI is a genuine OEM ground fault interrupter designed for Pureheat Hydronic Heaters and the full HHS Hose Handling System series. As a direct OEM replacement, the is built to Wacker Neuson's original electrical specifications, ensuring correct trip sensitivity and circuit protection performance across compatible units. Verified fitment covers the Pureheat Oil Burner, Gas Burner, and Diesel Hydronic Air Heater models, as well as HHS hose handling systems including the HHS1101, HHS1251, HHS1701, HHS2200, HHS2202, HHS2502, HHS3000, HHS3002, and HHS3004. Keep a spare on hand to restore safe, code-compliant electrical operation without delay.
Key Features
- OEM-Spec Ground Fault Protection — Matched to Wacker Neuson's original trip-current rating for this circuit, so the GFI responds correctly to fault conditions without nuisance trips or under-protection.
- Direct Inline Replacement — Connects into the existing wiring harness at the same inline position as the original, with no re-wiring or adapter hardware needed.
- Broad Fitment Across Pureheat and HHS Families — Confirmed for Pureheat Oil Burner, Gas Burner, and Diesel Hydronic Air Heater models, plus HHS1101 through HHS3004 hose handling systems.
- Sustained Heating System Uptime — A functioning inline GFI keeps hydronic heating circuits operating; a failed or tripped unit that cannot be reset will shut down heat output entirely, making a quality replacement critical on cold-weather jobsites.
- Electrical Safety Compliance — Ground fault protection is a code-required safety function on these heated systems; using a genuine OEM part maintains the designed level of personnel and equipment protection.
An inline GFI (ground fault interrupter) monitors the electrical current flowing through a circuit and cuts power almost instantly if it detects current leaking outside its intended path — a condition that can cause electric shock or equipment damage. In Wacker Neuson's Pureheat hydronic heaters and HHS hose handling systems, the inline GFI sits in the supply line to protect both the operator and the heating components from ground fault events. When the GFI fails or cannot be reset after a trip, the circuit loses power and the heating system stops functioning entirely, making prompt replacement essential for continuous cold-weather operations.
