Note - If water is allowed to freeze in the system, serious damage to the pipe work and pump may occur. Failures of
this type will invalidate warranty. To best avoid this damage, completely drain the water system.
WARNING - The power source must be turned off before draining and refi lling this Water Heater.
1. Drain the complete freshwater system either using the pump or a drain valve.
2. Open all the faucets (including the Water Heater drain valve) and allow pump to purge the water from the
system, and then turn the pump off.
3. Disconnect the pump and turn on to purge into an adequate basin. Only reconnect the pump when water
system is to be used.
4. Remember to leave all faucets including the Water Heater drain valve open to avoid any damage (except for
Whale Twist™ Deck Shower if installed).
