Opus One
2.2 Compressor Unit Installation
WARNING
As per manufacturer recommendations, inspect all gaskets and o-ring surfaces to ensure
they are present, undamaged, and clean. A missing or damaged o-ring could result in
rapid, catastrophic release of high-pressure helium. Do not use any lubricants on the
connectors. Always ensure connectors are mated properly to avoid any loss of high-
purity helium.

WARNING
Do not install the helium lines to the Opus One until instructed to do so in the order

may require factory repair of the Opus One unit.

documentation.

turer documentation.
