Installation Procedure Vacuuming Piping vavuum method to use vacuum pump 1 Detach the service port s cap of 3 way valve the valve rod s cap for 2 way valve and 3 way valves and connect the service port into the projection of charge hose low for gaugemanifold Then connect the projection of charge hose center for gaugemanifold into vacuum pump 2 way valve 3 way valve 2 Open the handle at low in gaugemanifold and operate vacuum pump If the scale moves of gause low reach vacuum condition in a moment check the step 1 again 3 Vacuumize for over 15min And check the level gauge which should read 0 1 MPa 76 cm Hg at low pressure side After the completion of vacuumizing close the handle Lo in the vacuum pump Check the condition of the scale and hold it for 1 2min If the scale moves back in spite of tightening make flaring work again then return to the beginning of the step 3 4 Open the valve rod for the 2 way valve to an angle of anticlockwise 90 degree After 6 seconds close the 2 way valve and make the inspection of gas leakge 5 No gas leakage In case of gas leakage tighten parts of pipe connection If leakage stops then proceed the step 6 If it does not stop gas leakage discharge whole refrigerants from the service port After flaring work again and vacuumize fill up prescribed refrigerant from the gas cylinder 6 Detach the charge hose from the service port open 2 way valve and 3 way Turn the valve rod anticlockwise until hitting lightly 7 To prevent the gas leakage turn the service ports cap the valve rodis cap for 2 way valve and 3 way s a little more than the point where the torque increases suddenly CAUTION If the refrigerant of the air conditioner leaks it is necessary to make all the refrigerant out Vacuumize first then charge the liquid refrigerant into air conditioner according to the amount marked on the nameplate 23
