Anti-Siphon Device - Tuthill Fill-Rite 700V Serie Manuel D'installation, Fonctionnement Et Securite

Anti-Siphon Device

Your 700V Series pump comes from the factory anti-siphon
ready, easily allowing you to install an anti-siphon tube back
to the tank. An anti-siphon device (sometimes called a
vacuum breaker) is important because it will break a liquid
siphon if there is an open nozzle or a leaking hose below the
fluid level in the tank when the pump is turned off. Fill-Rite
recommends that an anti-siphon tube be installed from the
pump outlet back to the vapor space in the tank using kit #
700KTH1067.
The accompanying illustration shows where and how to install
the tube so that it terminates in the vapor space at the top of
the tank. The tube must terminate in the vapor space; if it
terminates below the fluid level in the tank, it will not prevent
siphoning. It is also very important that there are no liquid
traps in the tubing. The tubing must have a continuous slope
from the pump down to the tank. Alternately, the tubing can be
connected into any opening in the top of the tank if the tank
adapter is not used. Use reducer bushings as required for proper fit and seal.
Anti-Siphon line installed.
Make a liquid-tight connection
using the appropriate sealant
from the adapter to the 1/4 anti-
siphon port on pump outlet using
a minimum of 1/4 metal tubing that is compatible with what ever liquid is being pumped. If the
anti-siphon tank line is not installed, leave the factory installed plugs at the pump outlet and
tank adapter in place.
Fill-Rite offers Anti-Siphon kit # 700KTH1067 (available through your Fill-Rite distributor).
This kit contains the necessary fittings and tubing to complete the installation as pictured in
this section.
WARNING! Threaded pipe joints and connections should be sealed with the
appropriate sealant or sealant tape to minimize the possibility of leaks.
