WARNING
High voltage is used to operate this equipment Failure to observe standard electrical safety procedures may result in serious injury Only persons qualied 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
certied 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 verication is
required for proper rotation direction Incorrect rotation will result in elevated sound and internal overload trip failure
