1.) Introduction
To obtain perfect operation of fans, thorough execution of all work stages, from
production to final assembly, is essential. Therefore, this guideline is to provide
assistance for all operations which are under your responsibility.
It is one of our policies that each fan leaving our works is submitted to strict
examination and a test run to check for output and vibration.
To this documentation additional documents are appended which should also be
noted. If you need more information about the fan than is included in this manual,
please contact your supplier directly. This manual only applies to directly driven
designs. Technical design of the fan is in accordance with DIN 24166 "Fans –
Technical Delivery Conditions".
