REFRIGERATION SYSTEM SAFETY
Working with refrigeration systems requires special equipment and training. If you are
not familiar with the operational theory for refrigeration systems and the special
requirements for performing service on a system, do
NOT attempt it. Use the following
precautions for working with refrigeration systems in Beckman instruments.
1. Always use protective glasses and clothing.
2. Do
NOT inhale refrigerant. It has an intoxicating effect and is harmful to your health.
3. Refrigerant can easily cause "frostbite". Be especially careful with liquid refrigerant.
4. Use caution when replacing a burnt out compressor. The oil in the compressor may
be very caustic or acidic. Use protective gloves.
5. Charge refrigeration systems with gas from the low side only. High side charging
may damage the compressor.
6. Do
NOT run a compressor without refrigerant in the system. Compressors are cooled
by the refrigerant and will burn out if there is no cooling.
