6. Once the hot tank is empty, reconnect the line between the hot tank and its solenoid.
7. Disconnect the line between the Cold Tank and its solenoid. Because the cold tank is air locked at
the top, it will not immediately begin to drain. Connect the line coming out the bottom of the
cold tank to the drain line setup previously. Then, disconnect the line in the top compartment
between the Cold Tank and outlet solenoid.
8. Water will begin draining from the Cold Tank once disconnected. Once the Cold Tank is empty,
reconnect the solenoid in the top compartment AND in the lower cabinet between the cold tank
solenoid and the cold tank.
