INJURY, AND DEATH:

• Service of air conditioning systems must

be done only by trained and experienced

technician to avoid overlling.

• T

echnicians opening refrigeration circuit in

automotive air conditioning systems MUST be

certied in refrigerant recovery and recycling

procedures in compliance with section 609

of Clean Air Act Amendments of 1990. For

 WARNING: USE ONLY R-134A REFRIGERANT

WITH THE A/C MANIFOLD GAUGE SET

WARNING: READ, UNDERSTAND AND FOLLOW ALL INSTRUCTIONS AND WARNINGS BEFORE

OPERATING THIS TOOL. FAILURE TO DO SO MAY RESULT IN PERSONAL INJURY AND/OR

PROPERTY DAMAGE AND WILL VOID WARRANTY.

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 Manifold Gauge Set.

3. There are certain applications for which this A/C Manifold Gauge

Set was designed. It will do the job better 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. Protective clothes and nonskid

footwear are recommended when working. Wear restrictive hair

covering to contain long hair.

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 qualied 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

xtures; and any other condition that may affect proper operation.

Any part that is damaged should be properly repaired or replaced by

a qualied technician.

10. Replacement parts and accessories. When servicing, 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 alcohol 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 qualied technician.

13.

Industrial applications must follow OSHA requirements.

14. People with pacemakers should consult their physician(s) before

using this product. Electromagnetic elds 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.

15. The warnings, cautions, and instructions discussed in this

instruction manual cannot cover all possible conditions and situations

that may occur. It must be understood by the operator that common

sense and caution are factors, which cannot be built into this product,

but must be supplied by the operator.

16. ONLY USE REFRIGERANT R-134a WITH THIS A/C MANIFOLD

GAUGE SET.

17. 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.

18. Keep hands away from the moving parts and hot parts of

vehicle’s engine.

19. Read and understand all instructions and safety precautions

as outlined in the vehicle manufacturer’s manual for air condition

servicing. Only qualied mechanics that are trained in servicing air

conditioning systems should use this product.

20. 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.

21. Refrigerant can cause severe frostbite if it comes in contact with

skin. Follow the safety warnings and instructions provided by the

refrigerant manufacturer.

22. Do not disconnect any pressurized hose. Pressurized refrigerant

can cause severe injury.

23. Use caution when opening an air conditioning system line or

can of refrigerant. When checking, always place a towel around the

service valves of the air conditioning unit and Red and Blue Couplers

(22 and 23).

24.

Keep refrigerant away from excessive heat as pressure in the

container could increase enough to rupture the can.

25.

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.

26. Only use refrigerant in a manner consistent with the air

conditioning system’s repair manual.

NOTICE: Indicates important information, which if not

followed, MAY cause damage to equipment.

SAFETY GUIDELINES / DEFINITIONS

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 (lling) the system.

c. For checking, attach the Yellow Hose (18) to both branches of the T-tting (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. Specic procedures for each individual system type

COMPONENTS AND FUNCTIONS

OPERATION

Read the ENTIRE SAFETY WARNINGS section at the beginning of this manual before set up or use of this product.

WARNING:

TO PREVENT EXPLOSION, SERIOUS INJURY, AND DEATH: Service of air conditioning systems must be done

only by trained and experienced technician to avoid overlling. Technicians opening refrigeration circuit in automotive air

conditioning systems MUST be certied in refrigerant recovery and recycling procedures 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

WARNING:

TO PREVENT SUDDEN LOSS OF CONSCIOUSNESS, AND DEATH: Connect and use in a well ventilated area

ONLY. Refrigerant can displace air if allowed to accumulate, causing sudden loss of consciousness followed by death. This

can happen WITHOUT FEELING SHORTNESS OF BREATH.

Coupler Valve (22, 23) operation:

CCW = Close

CW = Open

WARNING:

TO PREVENT EXPLOSION, SERIOUS INJURY, AND DEATH: Do not open the red HP Manifold Valve unless

requested to do so during the recovery/evacuation procedure. Refrigerant is under great pressure. Attempting to add

refrigerant through the HP side of the system may cause the refrigerant can to explode.

Note: Throughout this manual:

HP means High-pressure

LP means Low-pressure

CW means Clockwise

CCW means Counterclockwise

Note: Procedures such as charging refrigerant through the HP side of the system and adding lubricant to the system are

beyond the scope of this manual.

Note: For additional information regarding the parts listed in the following pages, refer to the Assembly Diagram near the

end of this manual.

TO PREVENT SERIOUS INJURY FROM TOOL

FAILURE: Do not use damaged equipment. If

abnormal noise, vibration, or leaking air occurs, have

the problem 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.

3. When storing, keep the set clean and dry. Also,

connect the Red Coupler (22) and the Blue

Coupler (23) to its corresponding Coupler Storage

Plug (7 or 6 respectively) to prevent contamination.
