11. OPTIONAL EQUIPMENT
FOOT-VALVE: if the difference in level
between the liquid surface and the suction
cone is more than 3.5M, this system should
be used to ensure optimal priming of the
pump.
2-WAY VALVE: located at the pump outlet, this
valve allows two different supply settings to be se-
lected using a manual lever. This system is used if
one of the two outlets is required for product mixing,
or serving two different lines. Before using the rele-
vant lever during operation, decrease the number of
pump revolutions to a minimum.
VACUUM PUMP: serves to ensure quicker, safer
priming. The instructions for using this system are
described and illustrated in the sticker located on
the tank (see the "STICKERS" chapter).
