INSTALLATION

Siphoning

Do not terminate the discharge line at a level lower
than that of the liquid being pumped unless a si-
phon breaker is used in the line. Otherwise, a si-
phoning action causing damage to the pump
could result.

Eductors

An eductor may be used in conjunction with an
FDF valve to increase dispensing rates and im-
prove efficiency. An eductor may also be used to
collapse the tank service hose after the tank has
been filled or emptied.

Contact the Gorman-Rupp Company or an author-
ized distributor for specifications and performance
data on eductors or FDF valves.
