Safety Precautions
1. Never close the compressor discharge valve while the system is operating.
2. Keep hands clear of the fans and belts when the system is running, especially when opening or
closing the compressor service valves.
3. When working with refrigerant, always wear eye protection; refrigerant can cause severe damage
to the eyes.
4. Never apply heat to a sealed refrigerant system or container.
5. Refrigerant produces phosgene gas when exposed to an open flame. Phosgene gas is hazardous.
It is colorless and is detectable by its unpleasant odor. Phosgene gas can cause severe respiratory
irritation and exposure can be fatal.
6. Exercise caution when working near exposed coil fins. Fins are extremely sharp and could cause
painful lacerations.
Refrigerant Precaution
Although Freon is a safe refrigerant, certain precautions must be observed when handling or servic-
ing any system which uses this cooling medium. If released into the atmosphere when in a liquid state,
refrigerant will evaporate rapidly and will freeze anything it comes in contact with. Frostbite could occur
from exposure to Freon.
