Frequently asked questions

HOW DO I TURN THE SYSTEM ON OR OFF?


From the hose handle you have a switch that turns on or off the electric floor brush and/or the central vacuum motor. Each inlet is wired back to the central vacuum unit with low voltage wire. On a Retractable Valve, there is a switch to turn the system ON anf OFF. Low voltage wire does not require installation by an electrician.




CAN I USE TWO INLET AT THE SAME TIME?


Apart from where this has been provided for at the planning stage, domestic central vacuum installations normally envisage operation by a single user.

Nevertheless the option of two or more simultaneous can be provided for at the time of planning the installation. Ask us!




IS IT POSSIBLE TO VACUUM WITHOUT A HOSE?


Not from an inlet valve on the wall but, it is possible to use the sweep inlet (if one is installed) as a type of hose-less vacuum.




HOW OFTEN DO I NEED TO CLEAN OR REPLACE FILTERS?


Those central vacuum units which incorporate a system which monitors maintenance requirements (VAC DIGITAL) will show this on the display panel. For units which don’t have this facility, dependant on the level of usage we recommend emptying the dust container and changing the filter every two months. This should be used as a guide but everything depends on the characteristics of the installation, the central vacuum unit selected and the habits of the user of the system.





INSTALLATION

WHEN SHOULD A CENTRAL VACUUM BE INSTALLED?


The installation of our system is very simple. It is recommended that it’s carried out when the home is being constructed or when it is having alterations done to it.. Nonetheless we treat each individual project on its merits so please send us your own requirements for evaluation.




THE LARGER, MORE POWERFUL UNIT THE BETTER?


No, each home and/or Project requires a technical study to determine which central vacuum is best suited to provide the required power to the number of inlet valves, determined by the size and layout of the installation.

At SACH UK we seek to optimize these variables and adapt the system to your specific requirements to ensure that you get the maximum benefit from your system and there is no unnecessary expense.




WHY NOT USE MORE INLETS AND SHORTER HOSES?


Each installation requires the correct number of inlet valves. On conventional inlet valves. our experience tells us that an 8 metre hose provides an ample reach and just the right amount of manoeuvrability.

Wherever possible we seek to locate inlet valves in transit areas (corridors, hallways, etc .) so that we have sufficient reach to clean into all the different rooms in the house. The use of a shorter hose together with several inlet valves is not correct because in doing so, our radius of action would be severely limited and the user would be constantly needing to plug in and unplug the hose with each change of location..




CAN THE NETWORK OF PIPES GET BLOCKED?


When installing the system care is taken to provide each valve with an anti-obstacle connecting elbow which prevents any item that might cause a blockage passing into the system.

At the same time the ducting has a greater diametre (51mm) than the flexible hose (32 mm.) Should you ever accidentally vacuum up an object or garment which becomes trapped in the system we recommend that you get in contact with our technical department.




WHERE CAN THE CENTRAL VAC UNIT BE INSTALLED?


In the case of a detached house the best place to locate the central vacuum unit is the boiler room, utility room, garage or cellar/basement.

In the case of a flat or an apartment the best location would be in the utility room should there be one or within a kitchen cabinet.

Consult our Technical Department for the best location for your central vacuum unit.





SAFETY

IS IT POSSIBLE TO VACUUM PLASTER AND BUILDING RESIDUES?


Definitely not! Your central vacuum unit was not designed to vacuum up building residue.

You need to bear in mind that many of the materials used in construction (plaster, cement etc. ) are made up of very fine particles which are often not captured by the filters meaning that they pass directly to the motor with the danger of reducing both its performance and its working life.




CAN I VACUUM UP GLASS?


In principle yes, provided that the pieces are of a size which would not cause obstructions in the system.




IS IT POSSIBLE TO VACUUM WATER?


Your central vacuum system has been designed to vacuum up liquids and potentially combustible materials within reason, like hot ash. To do so you should always use our Ash and Liquid Interceptor, which is specifically designed for this purpose.

By doing this we are harnessing the suction power of our central vacuum system to intercept liquid and ash without the potential for problems within the network of piping resulting from vacuuming up such materials or liquids.




CAN I VACUUM OUTSIDE BALCONIES AND GARDENS?


We don’t recommend it, because of the possible dampness of the dirt and dust absorbed by your central vacuum which is specifically designed to vacuum dust from within your home.

INSUFFICIENT  SUCTION POWER

IS AN INLET VALVE NOT SHUT PROPERLY?


Check all inlet valves to make sure they are properly shut and it's working correctly and then close it.




DUST CONTAINER FULL?


Check if the indicator light for the dust container or dust bag is illuminated (for models incorporating these features.) Switch off the central vacuum unit, disconnect it from the electrical supply and follow the instruction manual for emptying the dust canister or replace the dust bag (depending on model)




IS THE FILTER CARTRIDGE DIRTY?


Check if the indicator light for a filter change is illuminated (for models incorporating this feature.). Switch off the central vacuum unit, disconnect it from the electrical supply and follow the instruction manual for replacing or cleaning the filter.




ANYTHING OBSTRACTING THE AIR VENT?


Check to see that there is nothing blocking the vent. If you cannot detect anything or are unable to clear the blockage get in contact with our Technical Service Team.





WON'T START UP

REASON 1 - POWER LEAD NOT CONNECTED


Connect the power lead to the electrical supply. Follow the instruction manual and in case of need contact our Technical Service.




REASON 2 - ON/OFF BUTTON IS SWITCHED OFF


Push the switch to the ON position. Check whether or not another appliance plugged into the same socket as that for the central vacuum unit, works.




REASON 3 - THE ACTIVATION CABLE IS DISCONNECTED


Follow the instruction manual and in case of need contact our Technical Service Team or an authorized service engineer.




REASON 4 - INHERENT PROBLEM WITH CENTRAL VAC UNIT


A possible problem with the PC board or the motor. Unplug the central vacuum unit and contact our Technical Service Team or an authorized service engineer.




REASON 5 - THE MOTOR OVERHEATS


If the machine has a feature protecting against power overloads, press the power reset button, unplug the unit and wait 30 minutes before switching the unit on again, by plugging it in and operating the switch on the hose handle. If the central vacuum unit is not equipped with this feature or the problem persists contact our Technical Service Team.
