new oil reintegration, and charging. The values for the quantity
of gas recovered, quantity of oil recovered, vacuum time,

couplings bearing in mind that BLUE must be connected to the
low-pressure side and RED to high pressure. If the A/C system is
equipped with a single quick-connect coupling for high or low
pressure, connect only the relative hose.
