Jandy Heater Temperature-Rise Measurement Kit | R0336000

Temperature-rise measurement service kit; catalog applications include JXi, LXi, Legacy, LX/LT and Lite2 heaters.

The temperature-rise measurement kit. Heater, gas manometer and any separately required service equipment are separate; the catalog does not enumerate every kit component.

The manufacturer lists this kit for temperature-rise measurement on the named Jandy heater families. Use the exact installed heater manual and measuring location; the kit does not make every model share the same target temperature rise or flow setting.

The R0010400 manometer checks gas pressure; R0336000 measures temperature rise. These are separate service instruments and neither is a complete heater or a substitute for the matched diagnostic procedure.

Have a qualified technician follow the complete model-specific temperature-rise and flow procedure. This is service measurement equipment, not a universal replacement control-board temperature sensor or permission to bypass heater safety controls.

Jandy’s current Limited Warranty, H0333803 Rev AB, lists purchased replacement-parts coverage as 90 days, subject to the exact category and all statement conditions. Its internet-purchase exclusion contains exceptions for parts, pool accessories and valves under 3 inches; that does not extend an unconditional warranty to every installation. Qualified licensed installation/service where required, first-purchaser/original-site, geographic limits and labor/transport exclusions apply. Do not apply a complete heater’s advertised heat-exchanger term to this separately purchased part or kit.

The Fluidra 2026 heater-accessory ordering table, page134, identifies this exact part.
