Jandy r0303900 Inlet/Outlet Header – Replacement Kit for Hi-E2 Heaters
The Jandy R0303900 Inlet/Outlet Header is a genuine OEM replacement component engineered for the Hi-E2 EHE series pool and spa heaters (models 220/350 kBTU). It provides the machined bronze header assembly that connects the heat exchanger, siphon loop, and plumbing inlets and outlets for reliable circulation and structural integrity.Â
Key Features
-
Genuine Jandy (Zodiac) OEM header replacement kit.Â
-
Designed specifically for Hi-E2 series heater models (EHE 220 & EHE 350) with bronze construction. Provides combined inlet and outlet porting in a single header block for efficient plumbing and alignment.Â
-
Ships with hardware kit including bolts, gaskets, plugs and installation components (as listed in installation instructions).Â
-
Heavy-duty construction (shipping weight approximately 26 lb) for durability and long service life.Â
-
Maintains original factory flow geometry to ensure heater performance and warranty compliance.Â
Product Overview
The R0303900 Inlet/Outlet Header serves as a critical component in the hydraulic and thermal circuit of the Jandy Hi-E2 heater line. It interfaces between the heat-exchanger tube bundle and the external plumbing (return and supply lines) and also provides mounting for the siphon loop, temperature sensor, and high-limit switches. Over time, headers may corrode, crack or leak due to thermal cycling and chemical exposure. Replacing the header with this OEM unit ensures the heater returns to original specification and maintains safe, efficient operation.
The installation involves draining the system, removing side panels, loosening the siphon loop compression nut, removing bolts securing the flow valve and header, cleaning the header plate surface and installing the new assembly with new gaskets and hardware. Because this part is large and heavy, it’s best handled by qualified service technicians. For your e-commerce catalog or parts listing, highlight the high-value, performance-critical nature of the header kit and the fact that it's a factory-authorized replacement to maintain warranty and system longevity.
