Winterization:
When it’s time to store a motor home for the winter months or when freezing temperatures are expected, it’s crucial to properly winterize the Aqua-Hot to avoid serious damage, requiring a complete system replacement not cov-ered under the Aqua-Hot Limited Warranty Statement. The process of winterization consists of completely draining the domestic water from the system and pumping RV winteriza-tion antifreeze through to flush out the system.
Not winterizing the Aqua-Hot when freezing temperatures are present will result in SERIOUS damage to the Aqua-Hot’s Domestic Water Heating System.
