  • Verify your existing heater is a T-style configuration, not a flow-through or flo-thru style
  • Match the SKU or part number on your existing heater label before ordering
  • Check that your spa uses a HydroQuip control system — fitment is specific to HydroQuip-equipped units
  • Inspect your plumbing connections and union fittings before installation to confirm they match this heater's ports
