NOTE: 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.
NOTE: All refrigerant discharged from this
unit must be recovered WITHOUT
EXCEPTION. Technicians must follow
industry accepted guidelines and all local,
