Evacuating the System

Some systems are equipped with vacuum capabilities; all are equipped with purge capabilities. Purge gas
exits through the anti-siphon exit port assembly.
CAUTION: Never place any type of valve between the EM exhaust and the anti-siphon exit port
assembly.
MISE EN GARDE: Ne placez jamais un type de vanne quelconque entre l'échappement EM et
l'ensemble de l'orifice de sortie anti-siphon.
The EM is equipped with a vacuum meter assembly for determination of the vacuum level.
