Aqua-Hot 600D model and energy-source prep

Use the Aqua-Hot 600D page to capture AHE-600 model, 600-series energy-source notes, diesel status, controls, and service details.

Owner-safe checklist

Record the Aqua-Hot 600D or AHE-600 model, 600-series notes, diesel status, cabin-heat symptom, hot-water symptom, and control state.
Save photos of the model label, control panel, visible alerts, and service paperwork from normal owner access.
Shut the Aqua-Hot system off for leaks, unusual odor, overheating, unsafe hot-water condition, or repeated control symptoms.
Use Aqua-Hot support or qualified Aqua-Hot service for heating system, diesel source, engine-preheat, installed power, parts, warranty, or repair decisions.
