Before you buy — quick checklist

  • Confirm your Raypak heater assembly accepts a 3" x 3" square flange element
  • Verify your system runs on 230V before ordering — do not install on a mismatched voltage
  • Inspect the heater housing for corrosion or scale buildup before installing a new element — a fouled housing will shorten element life
  • Check that the existing element reads as failed with a multimeter (open circuit or very low resistance) before replacing
  • Note the OEM part number on your existing element to confirm 001802F is the correct cross-reference

Reading the checklist now prevents 90% of returns. Worth the 60 seconds.
