With a 7 gallon dirt tank and 640 air watts of suction power, the Electrolux PU3900C QuietClean Central Vacuum Unit is one vacuum you don't want to miss out on. Clean rooms up to 12,000 sq. ft by purchasing our Electrolux CS3000 central vacuum accessory kit that includes a 35 low voltage crushproof hose, 38 inch telescopic wand, 14 inch hard floor brush, dusting brush, crevice tool, upholstery tool, and hose hanger. Unlike some models, this central vacuum unit has a built-in LCD display that always tracks your systems performance and tells you when you need to empty out your dirt tank.

Hate changing filters? Don't worry, the Electrolux PU3900C utilizes a permanent self-cleaning filter that never needs to be replaced. Hate loud noises? No problem! Electrolux built this vacuum with sound-resistant technology. For extra peace of mind, the Electrolux PU3900C comes with a 10 year warranty.

Installing the Power Unit

The power unit is usually mounted on the wall in an "out of the way" location, such as a garage, basement, or storage room. They are installed 48 inches above the floor to allow for easy removal of the dirt tank, but never less than 12 inches from the ceiling because that does not provide adequate space for motor ventilation. Also, you should never install in an area where the temperature exceeds 120 degrees. Depending on wall type, you may need to use mounting bolts or anchors to hold the central vacuum power unit in place. Finally, connect the low voltage wires, tubing, and plug the unit into the wall.

Care and Maintenance

To get the most out of your central vacuum cleaner, you need to perform regular maintenance and safety checks. For example, the motor brushes should be checked by an authorized dealer after every 500 hours of use. You should also keep the power unit free of dust and debris by frequently dusting with a clean, soft cloth. Never use more than one inlet at a time, and never place anything on top of the power unit that could prevent proper motor ventilation. Finally, the Electrolux PU3900C cannot safely pick up construction debris.

If you ever have any trouble with your central vacuum unit, you are more than welcome to dial 1-866-972-8227 to speak with a trained vacuum specialist at absolutely no cost to you.

Q & A

Customers Questions and Answers
Question:what is the difference in "pig-tail" - (08/23/2017)
Answer:A pig tail is a cord that runs off the central vacuum hose to give it power rather than plug directly into the wall.
Question:Hi Evacstore, My Electrolux model 1590 has ceased to operate. I'm confident it's the motor (22 years old). I see that you sell a replacement motor for $98 which may be a fine fix. If I wanted to upgrade to a new model such as the PU3900C, will this work with my existing vacuum plumbing? I have no problem reconfiguring the connections to the power unit and adjusting the mounting as needed if the new unit will connect with the existing vacuum plumbing and activate properly. Thanks. - (06/04/2015)
Answer:The new PU3900 takes the same 2 inch pipe for the intake and the exhaust if you have one. Also the low voltage hooks up the same way as the 1590. We offer free installation advice from our technicians if you call 866-972-8227. In some cases you will need a small piece of flexible pipe to connect the pipe to the unit which we also sell.
