Water temperature fluctuates widely during use, feeling too hot near jets and cool elsewhere.

Safety: Monitor temperature to avoid hot spots that can cause discomfort or burns.

• Step 1 – Verify circulation: Ensure the circulation pump (if equipped) is running according to Catalina's programming. Listen for continuous low-speed flow.
• Step 2 – Adjust valves: Open diverter valves to distribute flow evenly across seats. Open air controls to help mix water.
• Step 3 – Clean filters and suctions: Remove and clean filters. Inspect suction covers for blockage.
• Step 4 – Run jets periodically: During heating, run the main jets occasionally to help mix water and equalize temperature.
