(ONLY SUITABLE FOR MG-2-R134A)
4.4.1 Please connect the blue hose to the blue quick coupling, red hose to the red quick
coupling, yellow hose to the vacuum pump intake port.
4.4.2 Quick coupling should be insert to automotive air conditioner connector’s connector
correspondingly, and then open the valve.

5 - SAFETY GUIDE
5.1.1 Please do not overexert when switching valves.
5.1.2 Manifold are high precision measuring istruments. After use, store manifold gauges
always in the carrying case.
1.1 The manifold has been designed especially to measure pressure in refrigeration equipment.
The manifold may only be used by trained technicians.
1.2 The manifold must not be used for other than refrigeration applications in connection with
refrigerants. The manifold is not suitable for other liquids or gases than those indicated on the
gauge.
1.3 The manifold must not be used with pressures higher than the pressure scale indicated on the
high presure gauge of the manifold.
1.4 Safe goggles and gloves must be worn at all time during the use of the manifold.
1.5 The gauges are correctly calibrated at the factory before shipment. If calibration is required,
remove the lens by first removing the bezel. Insert a straight blade screwdriver into the adjusting
screw on the gauge face.
1.6 Cleanup the connection interfaces in order to prevent contamination entering to refrigeration
system.
1.7 The charging hoses must be checked and clean of oil residue before each use. A visible
control is also necessary to ensure that the hoses and the connection are undamaged and tight.
1.8 Do not connector refrigerant directly it may cause personal injury.
1.9 Do not vent refrigerant into the atmosphere.
1.10 The seals and gaskets of the manifold gauge are parts of use and must therefore be replaced
from time to time. The manifold is tobe tested regularly to ensure the valves are still tight.
1.11 Make sure to use the right pressure gauge.
1.12 Manifolds are high precision measuring instruments. After use, disconnect all hoses from the
system and open valves and then store the manifold always in the carrying case.
1.13 Dispose of the manifold gauges according to the rules and regulations of the country of use.
