Oxygen gas reacts violently with oil, grease, and other common substances.
NEVER EXCEED specified test pressures. VERIFY the allowable test pressure by
checking the instr uc tion literature and th e de sign pressures on the eq ui p ment
nameplate.
DO NOT USE air for leak testing. Use only refrigerant or dry nitrogen.
DO NOT VALVE OFF any safe ty device.
