Frequently asked questions

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.





INSTALLATION

ONE INLET VALVE IS NOT WORKING


Either there is a faulty electrical connection or the inlet valve’s micro-switch is damaged.




SOME VALVES WORK OTHER DON'T


Disconnect the central vacuum from the power supply. Remove the dust canister from your central vacuum unit. Create a reverse suction effect by using a conventional vacuum cleaner at each inlet valve starting the process with the valve located furthest away from the central vacuum unit and systematically moving through all the valves. When inserting the hose into the valve cover any gap to ensure there is no leakage of debris. Check all the valves even though you may believe that the blockage has been removed at the beginning of the process. In normal use check that the blockage has been resolved. If not contact our Technical Service Team.




THE CENTRAL VAC UNIT CONTINUES TO WORK EVEN WHEN VALVES ARE CLOSED


It is possible that the micro-switch on one of the inlet valves is faulty or the PC board needs replacing. Whatever the reason, contact our Technical Service Team.




I HAVE ACCIDENTLY DRILLED THROUGH A PIPE IN THE SYSTEM


Accidents happen. There are two ways to get it sorted. Either call us or do it yourself. If you do it yourself... 1) Cut a square out of the wall where the pipe has been drilled 2) Cut out the defective pipe section.
2) Slide over the existing pipe a pair of slip couplings.
3) Insert the new pipe section in position.
4) Apply PVC glue to the both ends of pipes and never to the couplings, slide back into position the two slip couplings!
You are done!

HOW TO USE

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.
