Electrolux Central Vacuum\015 A few weeks ago I noticed intermittant power when runnig the vac. Today the area got very hot where the handle and wand connect. I have the type of tube to clean carpeting, with the two wires that connect to the wand. Thanks! Should I send out for repair or replace?\015

How to Identify and Fix Common Vacuum Problems ?

Our sources include academic articles, blog posts, and personal essays from experienced Vacuum Technicians :

When using the central vacuum system, you simply plug a hose into one of the inlet valves. The hose connects to the power unit, creating a powerful suction that pulls dirt, dust and debris through the tubing system and into a collection canister.
Ducted vacuum systems work by attaching a vacuum cleaner motor to a large pipe via a wall inlet on the outside of your house. This pipe runs throughout your house, opening up into a number of different access points called inlets.
Q: My Electrolux Central Vacuum has low suction? A: This is probably a clog within your central vacuum pipe. You should contact a local Electrolux central vacuum repair technician to get the clog out without any damage.
Push a broomstick through the hose to force any large clogs out. Take the end of the broomstick and feed it through the hose. Push the stick in slowly so you don`t accidentally break or puncture the hose. If there is a large clog in your hose, the broomstick will force it out from the other end.
The air flows in from the inlet filter, normally located under your instrument panel, directly into the inlet ports on your Artificial Horizon and Directional Gyro. The Suction Gauge is fitted between the Outlet and Inlet ports to give a differential pressure measured in Inches of Mercury.
Vacuum Pump Silencers/Separators

They work by absorbing the sound waves that are produced by the vacuum pump, which reduces the overall noise that is emitted. Vacuum pump silencers are typically made of metal or plastic, and they can be either inline or muffler-style.

Clean or replace the filter. A clogged filter will restrict the air flow, meaning there may not be enough suction to pick up dust and dirt. A simple filter change might be all your vacuum needs. Your vacuum should be cleaned every so often, as well.
The three major pipe options for installing a central vacuum plumbing pipe, flexible hose and vacuum tubing. There are essentially three major options for pipe choices for installing a central vacuum: Plumbing Pipe (such as schedule 40 PVC), Flexible Hose, and Vacuum Tubing designed specifically for central vacuums.
Central vacuum without a bag

A central vacuum that does not use a bag, has other perks just as attractive. First, the cyclonic suction assures a constant suction power while preventing the motor from overworking. Also, saving on dust bags is significant and eco-friendly!

The Main Parts Of A Vacuum Pump

We have the electrical motor on the back, the compressor at the front, a handle on top and a support base on the bottom. We then have an inlet which connects to the system to remove the air from the system and we also have the exhaust to disperse this to atmosphere.

Vacuum Pump Basics

The pressure ranges are placed into several groups: Rough/Low Vacuum: 1000 to 1 mbar / 760 to 0.75 Torr. Fine/ Medium Vacuum: 1 to 10–3 mbar / 0.75 to 7.5–3 Torr. High Vacuum: 10–3 to 10–7 mbar / 7.5–3 to 7.5–7 Torr.

Even when you use a vacuum cleaner to clean a floor, the vacuum doesn`t actually suck up the dust. Instead, the machine creates a volume of low pressure in its canister, and the air in the room gets pushed into the pipe by atmospheric pressure in order to fill that void, dragging the dust along with it.
With the hose in the exhaust, try gently flexing the hose starting at the exhaust and moving towards the open end. Or, use a broom handle, or a length of conduit long enough to reach where it`s clogged and gently try to dislodge it. A plumber`s snake would work too.
It is mechanical pump oil vapor. It is normal for the pump to emit vapor when pumping on a chamber from atmosphere. Since all the air that is removed from the chamber by the pump moves through the oil in the oil resevoir, some of that oil is vaporized when a lot of air is moving through it.
Water Consumption. Liquid ring pumps require fluid to create the seal between the inlet and discharge pressures, thus fundamental to their operation.
Clog located in the vacuum hose

Turn the unit on and feel the suction at the end of the hose handle. If there is no or low suction, then the clog is in the hose. You can remove the clog by running a long, stiff object through the hose, such as a butter knife, starting at the wall end.

If there is a clog in the vacuum, you won`t have good suction and the vacuum won`t work. The clog can be in the vacuum head, the hose or where the hose meets the actual vacuum.
The most common problems found in vacuum cleaners are low suction force, excessive noise, burning smell, vacuum not turn on, and overheating. These issues can be fixed by either cleaning the device or replacing some parts of the device. At times, it is best to seek a professional to fix the cleaner effectively.
While different factors affect how long a system lasts, many central vacuums can last 20-30 years, or even longer, depending on how often they are used.
But to completely remove those dangerous particles, it is recommended that all central vacuums be vented outside. Venting is a simple and relatively inexpensive process to guarantee to your customer that their living space can be dust and allergen free.
The hose contains both the high voltage (120v) for the electric powered brush and the low voltage (24v) used to turn the system on and off. Both sets of wires are molded into the hose. This hose will work with standard vacuum inlets.
Aside from being somewhat easier to coil and manage, the smaller diameter hose has an effect on performance as well. As you shrink the diameter of your opening, two things occur simultaneously. Your CFM (air volume) drops and your water lift (suction power) increases.
Yes, you can use standard, plumbing PVC found at any hardware store to run the pipes for your central vacuum system. It not only saves you time not having to scour the planet for hard-to-find central vacuum piping, it also saves you money because standard plumbing PVC is so much more affordable.
Power Usage

The amount of power used by a central vacuum system is roughly the same as that of a portable vacuum cleaner. Yet, it has 3 to 5 times the power of a portable vacuum cleaner. You are getting more suction power, which translates into more efficient cleaning, at no extra energy usage.

Central vac our central vac will not work unless the main vac in the garage is switched on manualy…. its sucking fine but i have to switch it off at the main switch in the garage after i have used it normaly i just plug in the hose and vac away and it switches itself off we have just had cable installed with a fisher guy in the walls do you think that would be the problem thanks a lot
ANSWER : It is possible that the low voltage wiring that controls your central vacuum has been damaged during the cable work. You can check to see if the low voltage relay is working by shorting the two terminals together at the unit. Just disconnect the two small (18-22 gauge) wires from the unit and short across the terminals where the wires connect. If the unit comes on, the vacuum is fine, and it is most likely the low voltage control wires that have been damaged. It should be a pretty easy fix, if you can get to where the wires are located. They are probably just pulled apart at a joint. Good Luck!!

Central Vac will not turn on.
ANSWER : These problems are nearly exclusively caused by a bad circut board and replacing it is the fix. Bad boards can cause many different effects so its nearly impossible to be sure. The 9v signal wire is not enough to short out an entire unit so it is unlikely the hose. If it is a direct connect system and you are pulling power from the 110 somehow that would cause main unit problems but that is unlikely at best. Sounds like a failed board to me.

ANSWER : The power head requires 120 Volts. Some hoses have a receptacle in the handle for the power head plug, and the hose has a cord at the wall inlet end that plugs into a receptacle. Some hoses have a plug at the wall inlet end that plugs into a 120Volt receptacle built into the inlet. The hose plugs into this receptacle when you push the hose into the inlet. The power for this built-in receptacle is wired with line voltage when the system is installed.
