WARNING!!
• Wear Safety Glasses / Wear Gloves
• If eyes come in contact with refrigerant, immediately flush with plenty of water.
Seek medical attention immediately.
• Keep the manifold in a dry place. Do not allow moisture to enter the unit.
• NOTE (R744): CO2 systems work under extremely high pressures. Only
professional technicians are recommended to service these systems. Please use
proper safety equipment while servicing.

BATTERY REPLACEMENT
1. Please take off the rubber boot, loosen the two screws and remove the rear case.
2. Use a flat screwdriver to take out the battery in the same direction as shown below:
3. Place a new battery into the compartment with the flat side facing out. Replace the rear
cover, screws (please note the screws must be tightened) and rubber boot.
PRE-SERVICE INSTRUCTIONS
1. Before connecting to the system, zero the gauge if necessary.
2. Close both valves on the manifold gauge set by turning the high and low knobs clock-
wise.
3. Connect the (red) hose to the high side port and the (blue) hose to the low side port on
the manifold gauge.
TESTING AND CHARGING
To properly diagnose the problem in the R/AC system, first check the system’s overall
performance. This includes monitoring the system’s pressure as well as leak testing. Your
manifold gauge set will give accurate readings of your system’s pressure.
NOTE: Be sure that the knobs on the manifold gauge set are in the closed position.
Always wear gloves and safety goggles when working with refrigerant.
1. Remove the protective caps from the system ports. Check for leaks at the ports.
2. Connect the low side service hose (blue) to the suction side of the compressor. Connect
the high side service hose (red) to the discharge side of the compressor.
3. If using adapters, make sure that they are fully tightened and piercing the access valve.
Failure to properly access the valve core will prohibit refrigerant flow.
IMPORTANT NOTES
• A system that has been opened or one that is found to be excessively low on refrigerant
pressure as a result of a leak, must be fully evacuated by means of recovery machine
and deep vacuum pump.
• A system that has been evacuated must be repaired, leak tested and evacuated to a
required level of vacuum.
• If charging on the liquid or high side, use only the high side valve on the manifold gauge
set. Make sure the low side valve is closed.
• After charging, test the system by turning on the engine or system and running the A/C
with both valves closed on the manifold.
• After testing, disconnect the hoses from the system and make sure to use a recovery/
recycling machine to evacuate any refrigerant remaining in the hoses or manifold.
