DO NOT VENT refrigerant relief valves within a building. Outlet from rupture disc
or relief v a lve must be v e n ted outdoor s in accorda nce with th e l atest edit i on of
ASHRAE 15 (Safety Code for Mechanical Refrigeration). The accumulation of
refrigerant in an en closed space can displac e ox ygen and cause asphyxiat i on.
PROVIDE adequate ve ntilation in accordance with ASHRAE 15, especial ly for
enclosed and low overhead spaces. Inhalation of high concentrations of vapor is
harmful and may caus e he art irregularities, un co nsciousness, or death. Misuse
can be fatal. Vapor is h eav ier than air and reduces th e amount of oxygen avail-
able for breathing. Product causes eye and skin irritation. Decomposition prod-
ucts are hazardous.
DO NOT USE OXYGE N to purge lines or to pr essurize a machine for any purpose.
Oxygen gas reacts violently with oil, grease, and other common substances.
NEVER EXCEED specified test pressures, VERIFY the allowable test pressure by
checking the instruction literature and the design pressures on the equipment
nameplate.
DO NOT USE air for leak testing. Use only refrigerant or dry nitrogen.
DO NOT VALVE OFF any safe ty device.
BE SURE that all pressure relief devices are properly installed and functioning
before operating any mac hin e.
