How to Choose a Power Unit
There is not a simple formula for choosing the correct size power unit for your cleaning system. If you live in a high altitude area (5,000 to 7,000+ ft. above sea level), you may need to move to the next larger size power unit, or go with a double motor unit.Remember, you can never have a power unit that is too big, or have too many inlets in your home!
