CAUTION
Threaded pipe joints and connections should be sealed with the appropriate sealant or sealant tape to minimize the possibility of leaks.
Anti-Siphon Device
Your FR700V Series 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.
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.
The 1/4" NPT opening in the side of the tank adapter terminates in the vapor space of the
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 1/4" NPT
opening is not used 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 ONLY works for tank top installations.
If not using the KIT700AS, you will need the KIT700AVB. This will allow you to connect a
line either back to the tank, or to the bung adapter.
Bung Adapter / Suction Pipe Assembly and Installation
FR700V Series pumps feature a 2" Bung Adapter with integral connection for an
anti-siphon device. When installing the suction pipe into the bung adapter, the suction
pipe must be inserted into the bung adapter correctly for proper operation. The suction
pipe threads into the tank adapter, and must be cut to a length that positions it at least
3" from the bottom of the tank.
1.
Measure and cut suction pipe to fit as described above.
2.
Examine the bung adapter to determine top and bottom for proper insertion of
the suction pipe. The bung adapter is labeled to help: the end marked "PUMP
SIDE" is the top of the bung adapter. Note that the internal threads for the
suction pipe are at the TOP of the opening.
3.
Wrap the threads of the suction pipe with the appropriate sealant for the fluid
being pumped. Insert the suction pipe (with the threaded side up) into the
bottom of the bung adapter until the threads engage.
4.
Tighten the suction tube into the bung adapter to create an air / fluid tight seal.
5.
Apply an anti-seize thread compound to the external threads on the bottom of
the bung adapter. Install the assembled bung adapter and suction pipe into the
bung opening on the tank. Tighten to a fluid / air tight seal.
6.
Install pump onto bung adapter using appropriate fluid sealant, and tighten to a
fluid / air tight seal.
