NOTE: This instruction covers operation of chillers equipped with Electro-Mechanical or Solid State Starters. If chiller is equipped with Variable Speed Drive, Form 160.00-O1 is to be used in conjunction with this manual.

WARNING

This equipment generates, uses and can radiate radio frequency energy and if not installed and used in accor- dance with the instructions manual, may cause interference to radio communications. Operation of this equip- ment in a residential area is likely to cause interference in which case the user at his own expense will be required to take whatever action may be required to correct the interference.

Additionally, any electronic equipment can generate EMI (electromagnetic interference) which, depending upon the installation and magnitude, may affect other electronic equipment. The amount of EMI generated is deter- mined by the source inductance, load inductance, and circuit impedances. Responsibility for assuring the satisfactory operation of other equipment included in the same power source as the YORK equipment rests solely with the user. YORK disclaims any liability resulting from any interference or for the correction thereof.
