CS6 Hard Wired for Power Management

use 14 gage Romex wire

CS6 version was designed for limited amperage availability. If for example you use the microwave oven or your air conditioner with the vacuum cleaner at the same time your circuit breaker might be overloaded.AFTER INSTALLING THE FOLLOWING ELECTRICAL CONNECTIONS YOU CAN ONLY RUN ONE APPLIANCE AT A TIME.

For Power Management CS-6 only

Hard Wiring model CS-8 or CSRM

Power Management to prevent overloading the circuit breaker:

Step 1. Turn off the breaker to the area you will i11stall the unit.Step 2. Find the power cable connecting the Microwave Oven to the Circuit Breaker.Step 3. Disconnect the exiting cable at the Microwave Oven. Reroute the cable to the Vacuum cleaner installation.Step 4. In the back of the vacuum find the wire connections.Step 5. Strip all 3 wires by about 5/8″.Tip: leave a loop in the wires from the vacuum to the wall where the cables are securely attached.Step 6. From the Microwave (or other appliance) connect the Black wire to “L”(line)(switched), the White wire into “N” (neutral) and connect the Ground wire under the washer screw head to “G”.Step 7. From the Circuit Breaker run a new 14 or 12 gage Romex cable to the back of the vacuum.Step 8. Strip the 3 wires and attach the Black to “L”, the White wire into the other “N” (neutral) and the GROUND wire to the other “G” connection.Step 9. Attach the wire cover (supplied) over the connections by guiding the wires through the opening at the bottom of the cover and screw cover into place.Step10. On the front side of the vacuum, toggle the switch to “SOURCE”.Step11. Switch-on the circuit breaker and check if the other appliance is operating.Step12. Now toggle the switch on the Vacuum to “VAC”.The other appliance will stop operating and the Central Vacuum is ready for use.

CS-8 Installation Instruction

The central vacuum should be mounted so that power supply cord can be plugged directly into a electrical outlet.Choose a place that is centrally located to maximize the reach with the vacuum hose.The minimum wall thickness is 3/8” the maximum is 1”.

The cut-out in the wall is 11“ wide X 6” high and requires 6” depth.Very important: If you installed the vacuum in a very small cabinet you must make provisions to exhaust the air from the vacuum out of the cabinet.Cut a hole in the cabinet a minimum , attach a louver to cover the hole.Use our part #AS-61 exhaust fitting with a diameter flex-hose to guide the warm air to the outside, or to where ever you prefer. See page 12 options.

Step A.  Tape the paper template against the surface at a comfortable operating heightStep B. With a skill saw cut along the dotted line of the paper templateStep C. Slide the unit, power cord in first, into the opening and secure by tightening the four attached screws behind the front panel with the “clamps”.Do not over-tighten.Step D. Check to be sure dust bag and motor filter are in place.

FIG 7.With a Phillip head screw driver adjust the distance between the clamp and the vacuum frame so the clamp reaches behind the frame.

FIG 8.Slide the vacuum with the cord into the opening. You might have to hold the 2 lower clamps up.

FIG 9.Now tighten the 4 screws the clamps will press against the back of the wall, Do not over tighten. When removing vacuum only unscrew 2 or 3 revolutions.

Installation Instruction


1) Inside the vacuum chamber you will find the flanged pipe with 4 screws.Attach the black flanged pipe into the back hole of the power unit.2) Install the vacuum valve about 3 to 4 feet from the vacuum. (the 2”dia. flex-hose is 4 feet long).3) with a circular saw, see above on the right and below, cut a 2-1/2” hole, with a jig saw open the hole so that the vacuum valve is flush with the wall.4) then route the 2” flex-hose form the vacuum to the valve.Route the supplied (low voltage, 24v.) white wire (the wire has 2 small leads) along the flex-hose to the back of the vacuum to the 2 yellow pigtails.IMPORTANT: leave 3” of slack at the connections.Do not: remove the 2 screws at the valve completely unscrew just enough to get the wires under the screw heads.5) connect the yellow wires with wire nuts outside the housing.6) secure the wires.

A) Pipe coupling to be press-fit to flanged pipe.#P-30B) Threaded pipe couplings, #D-900C) Flex-hose, 2“ diameter, 4 feet, #X-640D) Flanged pipe coupling attached to vacuum housing. #D-920E) Vacuum valve with reducer attached.#E-40NOTE for circle; screw the threaded pipe coupling counter clockwise into the flex-hose and press-fit the other side into the connectors.

Do not clean in washing machine. Let filter dry completely and reuse as needed.


TIP : Model CS-RM if you do not have any suction power, but the motor runs:

A) one of the gray hoses connecting the vacuum with a valve came loose or was not connected properly.B) The slider on the vacuums front panel is not closed.


  1. The most common cause is a clogged hose. Disconnect vacuum hose from cleaner, hold one end high up in the air and drop a quarter or similar object into the hose. If the quarter gets stuck the hose is clogged. Try to unclog the hose with a long stick or see below “cleaning the hose”.
  2. The bag is overfilled or fine dust has clogged the bag.Replace with new bag.DO NOT EMPTY AND REUSE
  3. The vacuum cleaning tools are clogged.
  4. Vacuuming large amounts of dust other than household dirt, such as dry-wall or fine wood dust can block the bags pores fast, even if the bag is fairly new.
  5. The motor filter is dirty and should be cleaned or replaced.
  6. If vacuum unit is installed in a air tight compartment the exhausting air cannot escape, the motor can overheat and shut off until it has cooled down and is restarted, see page 10


The stretch hose, besides all its’ conveniences, has a tendency to get clogged, especially if you have pets.

a) lift the hose up on both ends and dispense some liquid detergent into both ends.b) with a garden hose, holding both ends still up, fill ¾ with water.c) shake hose up and down, let detergent loosen the dirt.d) stretch the hose as far as you can ( 2 people required) and wash the dirt out with the full pressure of the garden hose. Repeat if necessary.e) Hang hose up, let hose drain and dry completely. up to 24 hours.


a) keep vacuum chamber clean. Use a brush to clean out dirt if accumulated.
