Anti-Siphon Device; Nozzle Boot Installation - Tuthill FILL-RITE 300V Serie Mode D'emploi

Anti-Siphon Device

Your series 300V pump comes from the factory ready to install an anti-siphon tube back to
the tank. An anti-siphon device (a.k.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 anti-siphon kit #KIT700AS be installed
from the pump outlet back to the vapor space in the tank.
Anti-siphon line
for the tubing, leave the factory installed plug in place.
Fill-Rite offers Anti-Siphon kit # KIT700AS (available through your Fill-Rite distributor).
This kit contains the necessary fittings and tubing to complete the installation as pictured in
this section. NOTE: This kit is required ONLY for tank top installations.
WARNING! Threaded pipe joints and connections should be sealed with the
appropriate sealant or sealant tape to minimize the possibility of leaks.

This illustration shows where 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 very
important there are no liquid traps in
the tubing; it must have a
continuous slope from the pump
down to the tank, and 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.
We recommend using the anti-
siphon tank adapter with a ¼ NPT
opening in the side. This opening
terminates in the vapor space of the
Tank Adapter
tank. Make liquid-tight connections
using the appropriate sealant from
the adapter to the anti-siphon outlet
using a minimum of 1/4 metal tubing
that is compatible with whatever
liquid is being pumped. If the anti-
siphon tank adapter is being used
and the ¼ NPT opening is not used

Nozzle Boot Installation

The nozzle boot is installed
using the lower two screw holes
on the side of the boot. Use
supplied attaching hardware to
install the nozzle boot.
When the nozzle is mounted
correctly it will be in a horizontal
position.
