MD SilentMaster S900r2 Specifications

Important 240-Volt Electrical Requirements

The MD SilentMaster S900r2 requires a 240-volt electrical connection and is not compatible with a standard 120V household outlet.

The manufacturer specifies a 240V, 15-amp circuit and a NEMA 6-20R receptacle. A separate electrical circuit is recommended.

If you're replacing an existing central vacuum, verify that your home's electrical supply and receptacle are compatible before purchasing.

Not sure whether you need the 120V S900r or the 240V S900r2?

Contact Redmond Vacuum before ordering. Our experienced team can help you compare the models and determine which central vacuum best suits your existing electrical setup and cleaning requirements.
