WARNING
High voltage is used to operate this equipment . Failure to observe standard electrical safety procedures may result in serious injury . Only persons qualified and /or properly trained should
attempt to install, operate and maintain this equipment . These chillers come fully charged with refrigerant . Installation, and start - up should be accomplished by technicians who are fully
certified to handle refrigerants, as required by 40 CER Part 82, subpart F of the Recycling and Emissions Reduction Act . Scroll compressors are used in this equipment . Phase verification is
required for proper rotation direction . Incorrect rotation will result in elevated sound and internal overload trip failure .
