APPLICATION:
This gauge measures the level of refrigerant in R-134A AC systems by
checking the low side pressure.
NOTE:
It is important that your system is fully charged for maximum cooling, but not over-
charged, which could damage the compressor.
DIRECTIONS:
1. Start your engine. Never do this in a garage!
2. Run the air conditioner for 3 minutes.
3. Press the R-134A Gauge onto the low-pressure port of your AC system.
NOTE:
The low-pressure port will generally be found on the larger diameter line that be-
comes cool, located between the compressor and the evaporator. On most late model GM
& Ford cars it is located on the accumulator drier. If you can’t locate it, check your vehicle’s
service manual.
4. Remove gauge and view reading. Press the button on the side to reset gauge. See
chart below.
LOW 0~25 PSI System may require additional refrigerant.
FILLED 25~45 PSI System has proper amount of refrigerant.
ALERT 45~65 PSI System may be overcharged. DO NOT ADD
REFRIGERANT.
DANGER 65 + PSI Your system may have other problems.
IMPORTANT:
When adding refrigerant, check system’s pressure after adding one can. If
the pressure has not changed, do not add more refrigerant. Pressures listed are based on
averages for most vehicles at ambient temperatures of 75 to 85 degrees Fahrenheit. They
will be higher at temperatures above 85° and lower at temperatures below 75 degrees.

CARbON MONOxIDE HAzARD!
Engine use in enclosed area will build up
invisible, odorless, carbon monoxide that can cause
SERIOuS INjuRY
or
DEATH
.
Engine must be running to operate AC. Run engine only in well-ventilated area
.
Service of air conditioning systems can result in overfilling, creating a
serious
ExPLOSION HAzARD
, if done by an untrained or inexperienced
technician.
All Technicians opening the refrigeration circuit in automotive air conditioning
systems MuST be certified in a refrigerant recovery and recycling procedures
in compliance with Section 609 of the Clean Air Act Amendments of 1990.

WARNING:
Be very careful when working on a running engine. Hot parts can cause BURN
HAZARD. Never wear jewelry or loose clothing that can be entangled in moving parts.
