LEGEND NOTES:
1. If there is no fault in memory, the Fault LED will flash code 1.
2. Codes will be displayed with a 10-second Fault LED pause.
3. Slow flash is 1 flash every 2 seconds.
4. Fast flash is 2 flashes every 1 second.
5. EXAMPLE: “Flashing Code 2” is represented by 2 fast flashes fol-

IMPORTANT: When a compressor is removed from this
unit, system refrigerant circuit oil will remain in the com-
pressor. To avoid leakage of compressor oil, the refrigerant
lines of the compressor must be sealed after it is removed.
IMPORTANT: All refrigerant discharged from this unit
must be recovered without exception. Technicians must fol-
low industry accepted guidelines and all local, state and fed-
eral statutes for the recovery and disposal of refrigerants.
IMPORTANT: To avoid the release of refrigerant into the
atmosphere, the refrigerant circuit of this unit must only be
serviced by technicians which meet local, state and federal
proficiency requirements.
IMPORTANT: To prevent injury or death due to electrical
shock or contact with moving parts, open unit disconnect
switch before servicing unit.
