1. INTRODUCTION
This manual describes the recommended procedures for installation, operation, maintenance and safety
precautions for AVK channel penstocks.
Please read thoroughly all the instructions in the manual prior to installation, and contact an AVK
representative in case of any questions.
The manual makes reference to the “General Arrangement Drawing” (GAD). The GAD is the
drawing that is sent to and approved by the customer prior to the production of the penstock.
AVK assumes no responsibility or liability if the channel penstock is not installed, operated and
maintained in strict accordance with the procedures described in this manual.
2. SAFETY PRECAUTIONS
Standard safety procedures should be followed to prevent personal injury or equipment damage during
installation and maintenance.
•
Penstocks are usually of large dimensions and heavy. Appropriate lifting devices must therefore be
used for secure handling.
•
Penstocks shall be lifted from the main frame or from the yoke if applicable. Holes are available for
lifting eyes. Slings can also be used.
•
Never lift the penstocks in inverted positions. Do not use stems, slides or actuators as lifting points.
•
Passing through the penstocks' openings must never be attempted unless slides have been properly
secured. In any case, this type of work should be avoided unless it is absolutely necessary.
•
Penstocks must never be manipulated when the system is under pressure.
Personnel that is handling penstocks must be correctly trained to avoid accidents. The correct
observation of installation and maintenance instructions will not relieve the personnel from being
adequately trained. AVK will not be held responsible for any accidents arising from incorrect
handling or installation.
