4 INSERTING THE CHARGING KEY

CAUTION: If the Charging Key is not properly seated and turned to the stop, when the

Control Screw is opened, the water pressure will push the key out, causingwater to be discharged into the room.

4.1. Ensure that the arrow on the Charging Key shaft lines up with the symbol of the open

padlock (Fig 4.2). Push the Charging Key firmly in until the key is fully seated.

Turn the key to the stop, the key arrow should now be aligned with the closed padlock

symbol (Fig 4.3). If the Charging Key turns beyond this stop, it is not fully located.

Try again pushing the key upwards and turn until fully engaged. The key then should only

turn between the mechanical stops.
