serious personal injury. SAVE THESE INSTRUCTIONS
WARNING
TO PREVENT EXPLOSION, SERIOUS IN-
JURY, AND DEATH:
• Service of air conditioning systems must be
done only by trained and experienced techni-
cian to avoid overfilling.
• Technicians opening refrigeration circuit in
automotive air conditioning systems MUST be
certified in refrigerant recovery and recycling
procedures in compliance with section 609 of
Clean Air Act Amendments of 1990.

1. Keep work area clean and well lit.
2. Keep children away. Children must never be allowed
in the work area. Do not let them handle the A/C Mani-
fold Gauge Set.
3. There are certain applications for which this A/C
Manifold Gauge Set was designed. It will do the job bet-
ter and more safely at the rate for which it was intended.
Do not modify this A/C Manifold Gauge Set and do not
use this A/C Manifold Gauge Set for a purpose for which
it was not intended.
4. Dress properly. Do not wear loose clothing or jewelry
as they can be caught in moving engine parts. Protec-
tive clothes and nonskid footwear are recommended
when working. Wear restrictive hair covering to contain
long hair.
5. Wear ANSI-approved impact safety goggles and
heavy-duty work gloves at all times during setup and use.
6. Do not overreach. Keep proper footing and balance at
all times.
7. Maintain gauge with care. Keep the A/C Manifold
Gauge Set clean for better and safer performance.
Inspect hoses periodically, and if damaged, have them
repaired by a qualified technician.
8. Stay alert. Watch what you are doing, use common
sense. Do not operate gauge when you are tired.
9. Check for damaged parts. Before using any gauge,
any part that appears damaged should be carefully
checked to determine that it will operate properly and
perform its intended function. Check for alignment and
binding of moving parts; any broken parts or mounting
fixtures; and any other condition that may affect proper
operation. Any part that is damaged should be properly
repaired or replaced by a qualified technician.
10. Replacement parts and accessories. When servic-
ing, use only identical replacement parts. Use of any
other parts will void the warranty. Only use accessories
intended for use with this gauge.
11. Do not operate gauge if under the inuence of alco-
hol or drugs. Read warning labels if taking prescription
medicine to determine if your judgment or reexes are
impaired while taking drugs. If there is any doubt, do not
operate the gauge.
12. Maintenance. For your safety, service and maintenance
should be performed regularly by a qualified technician.
13. Industrial applications must follow OSHA requirements.
14. People with pacemakers should consult their
physician(s) before using this product. Electromagnetic
fields in close proximity to a heart pacemaker could
cause interference to or failure of the pacemaker. In
addition, people with pacemakers should observe the
following: Caution is necessary when near the coil, spark
plug cables, or distributor of a running engine.
16. The warnings, cautions, and instructions discussed
in this instruction manual cannot cover all possible condi-
tions and situations that may occur. It must be under-
stood by the operator that common sense and caution
are factors, which cannot be built into this product, but
must be supplied by the operator.
17. ONLY USE REFRIGERANT R-134a WITH THIS A/C
MANIFOLD GAUGE SET.
18. Do not 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.
19. Keep hands away from the moving parts and hot
parts of vehicle’s engine.
20. Read and understand all instructions and safety
precautions as outlined in the vehicle manufacturer’s
manual for air condition servicing. Only qualified me-
chanics that are trained in servicing air conditioning
systems should use this product.
21. When warming up an engine in preparation for
checking of the A/C system, make sure the vehicle’s
transmission is placed in “Park” and the emergency
brake is applied.
22. Refrigerant can cause severe frostbite if it comes in
contact with skin.Follow the safety warnings and instruc-
tions provided by the refrigerant manufacturer.
23. Do not disconnect any pressurized hose. Pressur-
ized refrigerant can cause severe injury.
24. Use caution when opening an air conditioning sys-
tem line or can of refrigerant. When checking, always
place a towel around the service valves of the air condi-
tioning unit and Red and Blue Couplers (22 and 23).
25. Keep refrigerant away from excessive heat as pressure
in the container could increase enough to rupture the can.
26. Do not discharge refrigerant into the atmosphere.
Capture refrigerant into an approved recovery container
(not included), and then dispose of properly. Contact your
local Hazardous Waste Authority for disposal guidelines.
27. Only use refrigerant in a manner consistent with the
air conditioning system’s repair manual.

INSTRUCTIONS

APPLICATIONS
1. The Red HP Gauge (3) is used to measure high pressure compressor discharge side pressure.
2. The Blue LP Gauge (5) is used to measure low-pressure side suction or pressure.
3. The Manifold Valves (11) control the ow of refrigerant to and from the Yellow Hose (18), also called the Charge Hose.
4. The Coupler Valves (22,23) control the ow to the Gauges (3, 5) from the Red and Blue Hoses (17,19).
5. The Sight Glass (13) allows checking the appearance of the refrigerant.
6. The Yellow Hose (18), also called Charge Hose can be used three ways:
a. Refrigerant recovery/evacuation.
b. Charging (filling) the system.
c. For checking, attach the Yellow Hose (18) to both branches of the T-fitting (16) to reduce the risk of leaks.
7. The charge valve allows for simultaneous connection of a refrigerant recovery system.
8. General instructions for A/C service are outlined in this manual. Specific procedures for each individual system type
and model should be referenced in the vehicle manufacturer’s specific A/C system service manual.
9. See Operation instructions that follow.

OPERATION
Read the ENTIRE SAFETY WARNINGS
section at the beginning of this manual
before set up or use of this product.
TO PREVENT EXPLOSION, SERIOUS
INJURY, AND DEATH:Service of air con-
ditioning systems must be done only
by trained and experienced technician
to avoid overlling. Technicians open-
ing refrigeration circuit in automotive air
conditioning systems MUST be certied
in refrigerant recovery and recycling pro-
cedures in compliance with section 609
of Clean Air Act Amendments of 1990.For
additional information regarding ozone
depletion and air conditioning service
regulations, visit EPA’s website: www.
epa.gov/ozone
TO PREVENT SUDDEN LOSS OF CON-
SCIOUSNESS, AND DEATH:Connect and
use in a well ventilated area ONLY. Re-
frigerant can displace air if allowed to
accumulate, causing sudden loss of con-
sciousness followed by death. This can
happen WITHOUT FEELING SHORTNESS
OF BREATH.
TO PREVENT EXPLOSION, SERIOUS
INJURY, AND DEATH:Do not open the red
HP Manifold Valve unless requested to do
so during the recovery/evacuation proce-
dure. Refrigerant is under great pressure.
Attempting to add refrigerant through
the HP side of the system may cause the
refrigerant can to explode.

WARNING
TO PREVENT SERIOUS INJURY FROM TOOL FAIL-
URE: Do not use damaged equipment. If abnormal
noise, vibration, or leaking air occurs, have the prob-
lem corrected before further use.
1. Before each use, inspect the general condition of
the A/C Manifold Set. Check for cracked or
broken parts, damaged Hoses (17,18,19), and
any other condition that may affect safe operation.
If a problem with the Set occurs, have it corrected
before further use.
Do not use damaged equipment.
2. Periodically, clean with a damp cloth using a mild
detergent or solvent.
