Aqua-Hot 200 Series fluid winterization prep

Use this Aqua-Hot 200 Series guide to document fluid, winterization, model, control, and service details before support.

Owner-safe checklist

• Record the 200 Series model, control-panel state, hot-water symptom, cabin-heat symptom, fluid status if visible, and winterization status.
• Shut the Aqua-Hot system off if there is a leak, unusual odor, overheating, or unsafe hot-water condition.
• Use Aqua-Hot support or qualified Aqua-Hot service for fuel, exhaust, hydronic fluid, installed electrical, heat, or parts decisions.
