COMPRESSOR (EMBRACO) (ULTRA-2)
Important Safeguards:
• Trained service personnel with the knowledge of servicing and troubleshooting refrigeration systems or
related components should be used.
• Always be alert of smell and sounds (arching, popping and humming) coming from the compressor. Discon-
nect power or unplug immediately and get away.
• Always ensure main power is disconnected before any removal of a protective cover.
• Compressor oil and refrigerant being vented can create a hazardous condition of chemical burn, frostbite or
fire.
• Never reset a breaker or replace a blown fuse without checking the compressor or related components for a
short circuit or ground fault condition first.
• Always wear and use the appropriate safety gear when servicing a refrigeration system. Protective gloves,
eyewear, shoes, clothes and tools.
• If compressor ground fault condition exists, keep power off, disconnect power leads, mark or tag compres-
sor to indicate ground fault or defective compressor before replacing with a new compressor.
