Electrolux Quiet Clean PU3650, Installation Manual

Installation Step 2: Decide 
how many inlets you will need.

To make sure your central vacuum system reaches 

every room throughout the house, you must fi rst

determine the number of inlets you will need and 

where to place them. One inlet valve can serve

700-800 square feet (63-72 sq m). Use only interior 

walls if possible, so you won’t have to deal with

insulation typically found in exterior walls.

Installation Step 3: Decide 
where to place inlets.

Good locations are centrally located in hallways or 

closet walls and/or doorways. Do not place inlets

behind doors or furniture.

Existing home:

 The inlet valve must be within 6 feet 

(1.83m) of an electrical outlet to provide power to the 

powerhead. A switch on the handle sends a signal 

through “low-voltage” (24 volt) wiring to turn the power 

unit on and off.

New construction:

 If your home is under construction, 

you should consider using “electrifi ed” inlet valves. 

Electrifi ed valves have low-voltage and household

wiring connections built in, so there’s no need for

a nearby electrical outlet. Inlet valves should be

installed before drywall is hung. Installation must

be coordinated with an electrician to hook up the

electrical line after the tubing has been installed 

(electrifi ed valves sold separately). 

Choosing the right spot for the
inlet valve.

Use a stud fi nder, or sound out the wall, to make sure 

the site for the inlet valve is between the studs and 

that the space is open behind the wall board. Also 

check the other side of the wall to make sure it’s clear 

of obstructions such as utilities and outlets. 

Caution: 

Do not install an inlet behind a door or in a wall 

that has a pocket door.

 Then have a helper hold the 

end of the hose at the proposed site for the inlet valve 

and take the other end and walk around the room(s). 

If you have no helper, use a piece of cord or string 

that is 30 feet (9.15m) long—the length of the hose. 

You want to be able to reach everywhere from fl oor to 

ceiling even with furniture in the way. You may have 

to choose a different location or add another inlet to 

cover the entire fl oor. Remember, one inlet usually lets 

you cover about 700-800 square feet (63-72 sq m). 

Repeat this on each fl oor of your home.

What about installing inlet valves
upstairs? 

Because there are fi nished walls above and below the 

second-fl oor sole plate, installing inlet valves upstairs 

can take a little more ingenuity. There are several

options: Place an inlet outside a closet wall and then 

run the tubing through the wall and through the inside 

of the closet and down 

(see Fig. 03, Page 07)

. 

Another option is to run the tubing up into the attic 

then across and down to the inlet. Yet another

solution is to install the upstairs inlet valve directly

into the fl oor. 

Note: Although plastic inlet valves

are acceptable as long as they’re installed next 

to the wall where no one will step on them, metal 

fl oor inlets provide added durability. Hint: Do not 

install fl oor inlets where furniture will be.

To run tubing through a

closet, mount the inlet

outside the closet and 

run tubing into the closet

and down through the

closet fl oor.
