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.
CAUTION! To avoid equipment damage, DO NOT use
these units as a source of heating or cooling during the
construction process. The mechanical components and
fi lters will quickly become clogged with construction dirt
and debris, which may cause system damage.
WARNING! 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,
refrigerant circuit oil will remain in the compressor. To
avoid leakage of compressor oil, refrigerant lines of the
compressor must be sealed after it is removed.
