S1 Vivaldi II Owner’s ManualPage 8There is a switch labeled ON / OFF on top of the controller box adjacent to the 15A/20Aswitch shown in the above photo. (The ON/OFF switch is hidden in the photo.) This switchmust be set to OFF if you do not have the Timer plugged in and it must be set to ON whenthe timer is installed. Also, the state of this switch is only sensed when the power cable isunplugged, then plugged back in. So if you need to change this switch you will need tounplug the machine for at least 5 seconds after you do so.WARNING: If you do NOT have the Timer installed but you have the switch set to ON, thepump will not come on when you try to pull a shot.4.3 Initial Installation Before Connecting PowerAfter removing the VII from its packing carton and setting it on the counter, check foradditional installation instructions that may be included. You should also have all theaccessories shown in the photo below including a rubber backflush disk (not shown).Tip the VII on its side. Twist all four rubber feet (3) hand tight as they may vibrate looseduring shipping. While performing that task, use a screwdriver to ensure that the four screwson the bottom (two on each side between the rubber feet) which fasten the two side panels(5) to the chassis bottom are tight. These steps will help ensure the quietest possibleoperation of your VII.Be sure you connect the included water hose to the threaded water inlet on the bottom of themachine. Proper connection is obvious since there is only one place it can attach. Theopposite end of the hose - which connects to the water supply - may require adapters fromyour local hardware store depending on your specific situation. Contact your VII dealer foradvice if the solution isn’t obvious. Also, your VII dealer may request that you check that yourwater hardness is below a certain level to ensure long life and trouble free operation.
