DO NOT VENT refrigerant relief devices within a building. Outlet from rupture
disc or relief valve must be vented outdoors in accordance with the latest edition
of ANSI/ASHRAE 15 (American National Standards Institute/American Society of
Heating, Refrigeration, and Air Conditioning Engineers). The accumulation of
refrigerant in an enclosed space can displace oxygen and cause asphyxiation.
PROVIDE adequate ventilation in accordance with ANSI/ASHRAE 15, especially
for enclosed and low overhead spaces. Inhalation of high concentrations of
vapor is harmful and may cause heart irregularities, unconsciousness, or death.
Misuse can be fatal. Vapor is heavier than air and reduces the amount of oxygen
available for breathing. Product causes eye and skin irritation. Decomposition
products are hazardous.
DO NOT USE OXYGEN to purge lines or to pressurize 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 safety device.
BE SURE that all pressure relief devices are properly installed and functioning
before operating any machine.
