The vacuum function of the 800 SERIES is designed to
remove moisture from the automobile A/C system by pull-
ing a deep vacuum. This mode is most often used after
completing a repair that required opening the A/C system to
the atmosphere. Moisture in an A/C system can cause er-
ratic operation and must be removed before recharging the
system with refrigerant.
MODE 2 Operational Steps
