  • Magnetic drive slowly starts to ensure that it’s well primed with water.
  • Water lubricated that should not be operated without water in the spa. If the pump does run dry, it has an internal safety device (thermal cut-off) that will automatically shut it off should it overheat. You can reset the pump by turning it off for 10 seconds then turn it back on.
