General
B-Tech AV Mounts recommends that a professional AV installer or other suitably
qualified person install this product.
Great care must always be taken during installation as most AV equipment is of
a fragile nature, possibly heavy and easily damaged if dropped.
If you do not fully understand the instructions or are not sure how to install
this product safely, then please consult a professional for advice and/or to
install this product for you. Failure to rnount this product correctly may
cause serious injury or death, both during installation and at any time
thereafter.
Do not mount any AV equipment that exceeds the specific weight limit of the
product you are installing.
This weight limit will be clearly stated on each product and its packaging and
will vary from product to product.
Product location
Please pay careful attention to where this product is located. Check load
capacity of the ceiling and girder/purlin prior to installation as some
structures are not suitable for installation or for any additional load.
Designed for indoor use, this mount is suitable for public or home
installation. If located in a public or frequently populated area ensure that
the product is out of the immediate reach of people. If any AV equipment is to
be suspended over the likely path or location of people then great care should
be taken to secure all parts of the installation from falling. As the product
will be installed on a high level, the installer should be careful to avoid
any hazards and have the correct safety equipment to carry out the
installation. When drilling holes it is essential to avoid contact with
electrical cables and water or gas pipes contained within. Use of a good
quality live wire detector and hidden object locator is therefore recommended.
Only drill into structures when you are sure it is safe to do so.
Fixing hardware
It is highly recommended that all fixing screws be used where supplied and
that the purpose of all other fixing hardware is fully understood. In some
cases more AV equipment fixing hardware will be supplied to accommodate
different models of equipment and set up configurations. The installer must be
satisfied that any supplied fixing hardware is suitable for each specific
installation.
If any fixing screws or included hardware are deemed not sufficient for a safe
installation then please consult a professional or your local hardware store.
Hazard limitation
When routing cables take advantage of any built in cable management features
that the product might provide and ensure that all cables are tidy and secure.
Check to see that any moving aspect of the product can do so unhindered by any
cabling.
Some products have moving parts and the potential to cause injury through the
crushing or trapping of fingers or other body parts. Particular attention to
the nature of moving parts is required especially when assembling installing
and adjusting during set up. Immediately after installation double-check that
the work done is safe and secure. Double-check all necessary fixings are
present and are of ample tightness.
It is recommended that periodic inspections of the product and its fixing
points are made as frequently as possible (no more than 6 months apart) to
ensure that safety is maintained.
If in doubt consult a professional AV installer or other suitably qualified
people.
