WARNING
Wear safety goggles when working with
refrigerants. Contact with refrigerant can
cause eye injury.
Disconnect hoses using extreme caution!
Pressurized refrigerant may be present in
hoses. Point hoses away from you and
anyone nearby.
Disconnect power before servicing unit.
Incorrect use or connections can cause
electrical shock.
USE ONLY WITH REFRIGERANT TYPE
R-134a! Cross-contamination with other
refrigerant types will cause severe damage
to the A/C system and to service tools and
equipment. DO NOT MIX REFRIGERANT
TYPES THROUGH A SYSTEM OR IN THE
SAME CONTAINER!
Avoid breathing A/C refrigerant and
lubricant vapor or mist. Exposure may
irritate eyes, nose, and throat. To remove
R-134a from the A/C system, use service
equipment certified to meet the require-
ments of SAE J2210 (R-134a recycling
equipment). If accidental system discharge
occurs, ventilate work area before resum-
ing service.
Do not pressure test or leak test HFC-134a
service equipment or vehicle A/C systems
using compressed air. Some mixtures of
air/HFC-134a have been shown to be
combustible at elevated pressures. These
mixtures are potentially dangerous and
may result in fire or explosion causing
injury or property damage.
Additional health and safety information
may be obtained from refrigerant and
lubricant manufacturers.
