RECOVER
REFRIGERANT
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 proficiency
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
rotation direction . Incorrect rotation will result in elevated sound and internal overload trip failure .
! ATTENTION INSTALLER
3 Phase Scroll Compressor Units
• If this unit uses a 3 Phase Scroll Compressor, the following
instructions MUST BE followed:
- Unit power supply MUST BE wired in the proper sequence to avoid
damage to the 3 Phase Scroll Compressor;
- Scroll Compressors with INCORRECT rotation show the following
characteristics:
1.) High sound level;
2.) High suction pressure and low dischage pressure;
3.) Low current draw.
- If any of the three above characteristics exist, swap two of the
three supply wires at the disconnect and recheck compressor for
incorrect rotation.
