DO NOT USE YOUR WATER HEATER WHILE THE SYSTEM
IS WINTERIZED. Heating when filled with antifreeze (or while
drained) may cause unwarrantable damage to the water heater
and/or other components of the plumbing system.
Next Season:
• Thoroughly FLUSH the water heater and system with clean
drinking water through the hot and cold side before using.
• FILL water heater at City Water Connection & DRAIN
several times. See draining steps 17-19 (above).
• SANITIZE the water system per the recommendations
of your coach manufacturer. See page 20.
