Display shows PRR or Prr; spa may not start normal heating or filtration cycles.

Safety: Ensure all jets are open and slice valves are fully raised before running pumps.

• Step 1 – Open jets: Turn all jet faces fully counterclockwise to open.
• Step 2 – Run pumps: Use the topside control to turn each pump on and off several times to purge air. You should see strong water flow from jets.
• Step 3 – Bleed unions if needed: If a pump only hums, turn off power and slightly loosen the union on the pump discharge to release trapped air, then retighten and retry.
• Step 4 – Exit priming mode: After priming, the spa will automatically exit PRR mode or you may need to press a specific button per the Vita Spa manual.
