IMPORTANT SAFETY INSTRUCTIONS
WARNING
CAUTION
NOTE
Failure to comply with all instructions and warnings may lead to severe bodily injury or even
death. For optimal safety and functionality, it is advisable to have the product installed and serviced by a certified
service professional. Prior to using this product, installers, operators, and owners must carefully review these

IMPORTANT SAFETY INSTRUCTIONS
DANGER
WARNING
TO PREVENT EXPLOSION AND DEATH
• Air conditioning system service must be performed only by trained and experienced technicians to avoid
overfilling. Technicians opening the refrigeration circuit in automotive air conditioning systems MUST be
certified in refrigerant recovery and recycling procedures, in compliance with Section 609 of the Clean Air Act
Amendments of 1990. For additional information regarding ozone depletion and air conditioning service
regulations, visit the EPA’s website: www.epa.gov/ozone.
• Do not open the red HP Manifold Valve unless specifically instructed to do so during the recovery/evacuation
procedure. Refrigerant is under high pressure.
• Never attempt to add refrigerant through the HP (High-Pressure) side of the system, as this may cause the
refrigerant can to explode.
WARNING
Wear Safety Equipment
• Always wear ANSI-approved safety goggles and heavy-duty work gloves during setup.
• Wear goggles when working with refrigerants. Contact with refrigerants may cause serious injury.
• Wear gloves when working with refrigerants to prevent chemical burns or other injuries.
Prevent Leaks or Explosions
• Incorrect use or connections may cause leaks or explosions.
• Read and follow the instructions carefully and take all precautions to avoid leaks or explosions.
• Confirm that all associated devices are properly grounded before use.
California Proposition 65 Warning
• This product contains chemicals known to the State of California to cause cancer, birth defects, or other
reproductive harm.
Operate Only in a Well-Ventilated Area
• Ensure sufficient airflow to avoid the accumulation of refrigerant gases, which can displace oxygen and
pose serious health risks.
Avoid Moving Engine Parts
• Keep the gauge and hoses securely positioned away from any moving engine components to prevent
damage and injury.
Turn Off Engine and A/C System Before Setup
• Always turn off the vehicle's engine and air conditioning system before attaching the gauge to ensure safe
handling.
For Professional Use Only
• This manifold is designed exclusively for use by technically trained refrigeration and air conditioning service
technicians.
• Due to the unusually high pressure and presence of hazardous gases in all systems, misapplication could
result in serious injury or death.
• The manufacturer strictly warns against the sale of or use of this product by anyone other than
professionally trained personnel.
Certified Technician Requirement
• The procedure outlined is to be performed only by technicians certified in refrigerant recovery and recycling
procedures, as detailed in compliance with the Clean Air Act Amendments of 1990.

IMPORTANT SAFETY INSTRUCTIONS
TO PREVENT SUDDEN LOSS OF CONSCIOUSNESS AND DEATH
• Do not open the red HP Manifold Valve unless specifically instructed to do so during the recovery/evacuation
procedure.
• Refrigerant is under high pressure.
• Never attempt to add refrigerant through the HP (High-Pressure) side of the system, as this may cause the
refrigerant can to explode.
WARNING
TO PREVENT PERSONAL INJURY AND DEATH
IMPORTANT SAFETY NOTICE

• The refrigeration gauge has been pre-calibrated at the factory. However, due to handling and shipping, it may
require adjustment.
Adjustment Procedure:
1. Unscrew the center screw and hold it firmly using a screwdriver.
2. With your thumb and forefinger, grip the pointer near its center.
3. Gently turn the pointer to align with the zero mark.
4. Repeat this process carefully if the pointer does not align to zero.

MANIFOLD OPERATING INSTRUCTIONS
1. Purging
Purpose: To remove air and moisture from the manifold and lines.
Steps:
A. Ensure both manifold valves (A and B) are turned all the way in. The
system will now pump vapor, and both low and high-side pressures
can be read.
B. Attach the lines from the manifold to the SSV at D and leave the
connection one to two turns loose.
C. Tighten the line to the DSV at C.
D. Open both manifold valves (A and B) by 1/4 to 1/2 turn.
E. Cap the middle opening (E).
F. Slightly open the DSV (C) stem by 1/8 to 1/4 turn momentarily ("crack
the valve"). A high-pressure refrigerant surge will flow through the
lines and manifold, purging to the atmosphere at the loose D (SSV)
connection.
G. Tighten the loose connection at D (SSV) once purging is complete.
Purging should be minimized to avoid damage to the
atmosphere. Carefully test for leaks while the manifold
and lines are under high pressure. Correct any leaks immediately.
2. Observing Operating Pressures
Steps:
A. Close valve A completely (turn all the way in).
B. Close valve B completely (turn all the way in).
C. Slightly open the back seat of valve C (DSV).
D. Slightly open the back seat of valve D (SSV).
Important Safety Reminder: Always exercise extreme caution when following these
instructions to ensure the safe operation of your manifold gauge.

Gauge Calibration
The refrigeration gauge is pre-calibrated at the factory.
However, due to shipping or handling, minor adjustments may be necessary:
Dry Gauge Calibration:
• Unscrew the lens.
• Hold the center screw firmly with a screwdriver.
• With your thumb and forefinger, grip the pointer near its center and gently turn it to align with zero.
• Repeat the process if the pointer does not align with zero on the first attempt.
Wet Gauge:
• Wet gauges do not require zeroing.
• Ensure manifold valves and service connections are handled with care to prevent leaks or contamina-
tion.
• Use this equipment in a well-ventilated area to avoid inhaling refrigerants.
• Always consult the manufacturer's instructions for specific refrigerant charge, oil change, and servicing
recommendations.

1. Blue LP Side Gauge: Used to measure the low-pressure side suction or pressure.
2. Red HP Side Gauge: Used to measure the high-pressure compressor discharge side pressure.
3. Manifold Service Valves: Control the flow of refrigerant to and from the Yellow Hose, also referred to
as the Charge Hose.
4. Coupler Valves: Regulate the flow of refrigerant to the Gauges from the Red and Blue Hoses.
5. Optical Sight Glass: Allows visual inspection of the refrigerant to check its appearance and condition.
6. Yellow Charge Hose: The Yellow Hose is versatile and serves three primary purposes:
a Refrigerant Recovery/Evacuation
b. Charging (filling) the system with refrigerant
c. System Checking: To minimize the risk of leaks,
connect the Yellow Hose to both branches of the T-fitting.
7. Charge Valve: Permits simultaneous connection to a refrigerant recovery system for efficient servicing.
8. General A/C Service Instructions: This manual outlines general procedures for servicing A/C systems.
For specific procedures tailored to the type and model of an A/C system,
