Safety Precautions
General Practices
1. ALWAYS WEAR GOGGLES OR SAFETY GLASSES, refrigerant liquid,
refrigeration oil, and battery acids can permanently damage the eyes.
2. Never operate the system with the compressor discharge valve closed
3. Keep your hands, clothing and tools clear of the fans and belts when the
system is running. This should also be considered when opening and closing
compressor valves.
4. Make sure gauge manifold hoses are in good condition. Never let them come
in contact with a belt, fan pulley, or any hot surface.
5. Never apply heat to sealed air conditioning system components or container.
6. Fluorocarbon refrigerants, in the presence of an open flame or electrical short,
produce toxic gases that are severe respitory irritants capable of causing death.
7. Make sure that all mounting bolts are tight and the correct length for their
particular application.
8. Use extreme caution when drilling in the units. The holes may weaken
structural components, and holes drilled into electrical wiring can cause fire or
explosion. Drilled holes may also puncture pressurized system components
causing leaks, exercise caution when drilling close to coil, tubing, hoses and
other system components.
9. Use caution when working around exposed coil fins. The fins can cause
painful lacerations.
10. Use caution when working on a refrigerant or air conditioning system in any
enclosed or confined area with a limited air supply, Refrigerant gas will displace
air causing oxygen depletion resulting in suffocation and possible death.
11. EPA Section 608 is required to work on Air Conditioning Systems.
