Note: If just the cold water system is
being used, without water heater, the heater
tank is also filled up with water. Therefore,
order to avoid damage through frost, the
water contents must be drained by opening
the drain valve when the system is no longer
in use.

1. Disconnect power for water pump (main
switch or pump switch).
2. Open hot water taps in bathroom
and kitchen.
