Frequently asked questions

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!

SAFETY

IS THE SYSTEM SAFE? IS THERE A RISK OF ELECTRIC SHOCK ON CHILDREN?


There is definitely no risk, the system is completely safe.

The system is operated by low-voltage current so there is no safety risk should a child play with an inlet valve.




CAN THE UNIT BE INSTALLED IN THE SAME ROOM AS A BOILER OR ANOTHER POSSIBLE SOURCE OF COMBUSTION?


Yes, just like any other type of domestic appliance the central vacuum is an item of electrical equipment which does not affect other items. You should however take account of any regulations pertaining to other equipment located in the boiler room (for example lift equipment.)

In any event our Technical Department will provide the advice you need regarding installation options.




HOW CAN A CENTRAL VAC AFFECT SYMPTOMS ASSOCIATED WITH ASTHMA AND ALLERGIES?


Portable vacuums exhaust fine dust back into the living space. These allergens are breathed in, resulting in irritation to the lungs. Those who suffer from asthma and allergies are particularly affected by this. Central vacuums are more powerful than portable vacuums and convey the allergens to the vacuum unit located in a non-living space area and possibly outside. More dirt and allergens are removed from the living space. There is no emission of allergens into the living space.




DO I NEED TO CLEAN THE INSIDE THE PIPES PERIODICALLY?


It’s not really necessary since the dust mixed with the air circulates at high speed inside the pipe-work leaving no residue behind. Nonetheless should you consider it to be appropriate it is possible to clean the inside of the tubes by feeding serrated rubber balls into the system, which are designed with this specific purpose in mind. Ask us!





VACUUMED MATERIALS

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.

TROUBLESHOOT

Do I have to register my hands when I become a black belt?


No, that is an urban myth. Martial Artists are not required to register their hands.




Do I have to be in good shape before I start?


No, you will get into shape as you train. We have a series of exercises that you will learn as you progress through the ranking system which will enable you to perform the self defense techniques.




I am 31 years old, am I too old to start martial arts?


No, you are not too old to begin martial arts training. Kenpo regularly has students start from adolecense through their 50's and older. Kenpo is a practical and effective martial art that does not incorporate gymnastics.




What is the difference between Tae Kwon Do and Kenpo?


Tae Kwon Do is a Korean Martial Art that focuses primarily on kicking techniques. Some Tae Kwon Do schools also teach Olympic style fighting. Kenpo is a practical self defense system which trains the student for modern day self defense encounters. Kenpo students are taught to use their hands and feet with multiple strikes to multiple targets on each attacker, in a multiple attack situation.




I am very busy with my work schedule, how much time do I need to devote to kenpo classes?


The two 1 hour classes are week are recommended, as is practicing at home. As you progress through the ranks if you want more 1:1 attention we offer 30 minute private lessons which can further help hone your skills.




How long does it take to get a black belt?


In Kenpo Karate, it takes approximately 5 years to reach student black belt.




What sort of things should I consider when choosing a school?


My instructor Master Professor Bill Grossman has a great write up about choosing a martial arts school on his website here: http://grossmanskenpo.com/choose_school.php
