Carrier HFC-134a, Installation Instructions Manual

Page: 2 / 67

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
American National Standards Institute/American Society of Heating, Refrigeration
and Air Conditioning Engineers (ANSI/ASHRAE) 15. The accumulation of refriger-
ant 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. Inten-
tional misuse can be fatal. Vapor is heavier than air and reduces the amount of
oxygen available for breathing. Product causes eye and skin irritation. Decompo-
sition 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.
DO NOT USE air to leak test. Use only refrigerant or dry nitrogen.
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 VALVE OFF any safety device.
BE SURE that all pressure relief devices are properly installed and functioning
before operating any machine.
