******************

High gas pressure is present within the system and can cause serious injury if suddenly vented. Follow specified procedures when assembling and disassembling the self-sealing gas couplings on the flexible gas lines. Use caution to avoid puncturing the flexible gas lines.

Follow these instructions to ensure operator safety:

- Disconnect all components from the electrical power source before making component interconnections.
- Shut off the compressor power (with the switch) before connecting it to a power source. 
- Do not connect the cold head power cable to the cold head while the compressor is running.
