PR displayed after power-up; pumps may run automatically.

Note: PR indicates Priming mode on many Aquavia Spa systems and is not a fault.

• Allow priming: After power-up, let the spa run through its priming cycle. Open all jets to help release air from the plumbing.
• Exit priming: Follow the display prompts or wait for the system to automatically exit priming and enter normal heating mode.
• Check for air locks: If pumps continue to surge or PR does not clear, bleed air from pump unions and ensure water level is adequate.
