SPECIFIC PRODUCT WARNINGS AND PRECAUTIONS
WARNING!! ONLY USE REFRIGERANT R-134a WITH THIS A/C MANIFOLD GAUGE SET.
WARNING!! Never start an engine in an enclosed area (like a garage). A running
gasoline engine generates Carbon Monoxide; Carbon Monoxide is a colorless,
odorless gas that can cause serious injury and death, if inhaled.
1.
Always keep hands and fingers away from the moving parts and hot parts of
vehicle’s engine.
2.
Make sure to read and understand all instructions and safety precautions as
outlined in the vehicle manufacturer’s manual for air condition servicing. Only
qualified mechanics that are trained in servicing air conditioning systems
should use this product.
3.
When warming up an engine in preparation for testing of the A/C system, make
sure the vehicle’s transmission is placed in “Park” and the emergency brake is
applied.
4.
CAUTION! Refrigerant R-134a can cause severe frostbite if it comes in contact
with the skin. Always follow the safety warnings and instructions provided by
the manufacturer of R-134a refrigerant.
5.
Never disconnect any hose while the hose is under pressure. Pressurized
R-134a refrigerant can cause severe injury.
6.
Use caution when opening an air conditioning system line or can of
refrigerant. When testing, always place a towel around the service valves of the
air conditioning unit and High and Low Pressure Couplers (20 and 21) of the A/C
Manifold set.
7.
Keep refrigerant away from excessive heat as pressure in the container could
increase enough to rupture the can.
8.
Never discharge refrigerant into the atmosphere. Always capture refrigerant
into an approved recovery container (not included), and then dispose of properly.
Contact your local Hazardous Waste Authority for disposal guidelines.
9.
Only use refrigerant in a manner consistent with the air conditioning system’s
repair manual.
