Electrolux Quiet Clean PU3650, Installation Manual

Deciding where to mount the power unit. 

To be sure that dust and dirt are effectively removed 

from living areas in your home, mount the power unit 

in your attached garage. If you do not have an

attached garage, the basement, utility room, storage 

room or mud room is the best alternative location. 

Find a spot that is close to an electrical source, yet 

with plenty of room for air to circulate on either side of 

the unit. You’ll need a dedicated 15- or 20-amp circuit. 

Check the owner’s manual.

Installation Step 4:
Plan the tubing installation.

Before you install tubing to carry dust and dirt to the 

power unit, plan your route. Run the tubing beneath 

the sub-fl oor whenever possible because it makes

tubing easier to work with and creates the shortest 

path between the inlet valves and the power unit.

If the tubing has to run next to a water heater or 

chimney fl ue—for your safety and to comply with 

building codes—use metal central vacuum system 

tubing for that section. 

Hint: A local central vacuum 

system dealer may provide metal tubing.

 If the

tubing runs through an unheated attic or other

unprotected environment, wrap it with insulation to 

prevent condensation and the possibility of clogging.

Installation Step 5:
Install the inlet valves. 

Existing home inlet valve installation.

Directly beneath the proposed inlet site, use a fl at-

bladed screwdriver to wedge the molding aside. Then, 

take a wire coat hanger and snip a long straight piece 

from it. Insert the wire into the chuck of your drill and 

then holding the drill vertically beneath the intended 

inlet site, slowly drill down into the fl oor alongside the 

baseboard or where the wall and fl oor intersect.

Release the wire from the drill chuck and leave it in 

the pilot hole to serve as a locator. Then go to the 

basement and look for the wire protruding from the 

ceiling. 

Now you can see where the inlet valve is going to be 

above you. Measure from the wire to fi nd the center 

of the sole plate and wall cavity. 

Note: You may want 

to drill a 3/4" (1.9cm) diameter inspection hole to 

avoid cutting into the bottom of a stud or other 

inner-wall obstructions.

 Then using a fl ashlight 

and/or probe, inspect the interior of the wall to be sure 

there are no obstructions. If there are obstructions, 

you may have to move the inlet site. If there are no 

obstructions, drill a 2-1/4" diameter hole (5.7cm) in 

the bottom of the hollow wall through the sole plate. 

Make sure to cut in between the walls. The tubing is 2" 

(5.08cm) in diameter, so the hole will give you room 

to manipulate the tubing. Again, check for obstructions 

using a fl ashlight and a length of tubing. If there are 

no obstructions, go back upstairs and mark the inlet 

location on the wall. To do that, at the electrical outlet 

adjacent to the inlet site, measure up from the fl oor 

to the center of the outlet. At the proposed inlet site 

measure up from the fl oor the same distance. This will 

be the center of your inlet valve. If you prefer, you may 

locate the inlet at a more convenient height. Some 

homeowners prefer the inlet at fi ngertip height, about 

30" (76.2cm) above the fl oor.
