To drain the Conditioner, proceed as follows:
1. Shut down the entire system by clicking the System Shutdown button on the Browser window.
2. Switch OFF the Generator and MDR circuit breakers in the Generator Cabinet.
3. Prepare the Empty container to receive the used coolant. Place the end of the purge tool into the
container.
4. Disconnect the coolant input pipe from the Conditioner. The pipe connector seals automatically.
5. Connect the disconnected coolant input pipe to the purge tool. The connector is now unsealed, and
coolant can drain into the prepared container.

7. Coolant drains into the container, until the “Check Fluid” alarm stops the flow.
8. Switch OFF the MDR circuit breaker.
Note:
The Conditioner is now empty.

word Empty on the label, and copy the information from one of the coolant containers (Flush or Top-
ping) provided in the kit. See below for disposal.
