All workers handling the product must be aware of the weight of the components or assemblies

to be handled and manipulated during installation and maintenance.

It is essential that staff undertaking these operations are adequately trained and it is the

responsibility of the end user that only trained and competent staff undertake these duties.

This manual has been designed to assist, but it cannot replace quality training in the workplace.

However, the AVK technical staff is always available and ready to answer questions relating to

specific problems that may not be covered by this manual.

AVK's products are designed to be fit for purpose and to a high reliability standard. This

provides a safe, low risk product when used correctly for the purpose for which it was designed.

However, this assumes that the equipment is used and maintained in accordance with this

manual, and the user is advised to study it and to make it available to all staff that may need to

refer to it.

AVK cannot be held responsible for incidents arising from incorrect installation, operation or

maintenance. The responsibility for this rests wholly with the end user.
