WARNING
To avoid the release of refrigerant into the atmosphere, 
the refrigerant circuit of this unit must be serviced only by 
technicians who meet local, state and federal profi ciency 
requirements.
All refrigerant discharged from this unit must be recovered 
WITHOUT EXCEPTION. Technicians must follow industry 
accepted guidelines and all local, state and federal statutes for 
the recovery and disposal of refrigerants.
If a compressor is removed from this unit, system refrigerant 
circuit oil will remain in the compressor. To avoid leakage of 
compressor oil, the refrigerant lines of the compressor must 
be sealed after it is removed.
WARNING
This unit contains HFC-(R410A), an azeotropic mixture of R-32 (Difluoromethane) and R-125 (Pentafluoroethane). 
DO NOT VENT HFC-(R410A) to the atmosphere. The U.S. Clean Air Act requires the recovery of any residual 
refrigerant. Do not use R-22 service equipment or components on R410A systems.
WARNING!
WARNING! To avoid possible injury or death due to electrical 
shock, open the power supply disconnect switch and secure it 
in an open position during installation.
CAUTION!
CAUTION! Use only copper conductors for field installed 
electrical wiring. Unit terminals are not designed to accept 
other types of conductors.
SAFETY 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 CRF Part 82, subpart F of the Recycling 
and Emissions Reduction Act. Scroll compressors are used in this equipment. Phase verification is required for proper
