MDE-4340A Series 9800Q Pumps and Dispensers Installation/Operation Manual · January 2006 Page 3-3
Installation
Suction Pump
The pump and the tank should be located close to each other with as few changes in direction
of the supply line, as possible. This reduces the possibility of vaporization (gasoline only),
attains the highest possible flow rate, and results in a lower installation cost. Avoid long
supply lines and excessive vertical lifts. The dynamic lift for this unit is rated at 12 feet (4m)
for gasoline and 13 feet (4m) for diesel and can vary according to conditions of the installation
and fuel temperature.
If a pump is to be used with an above-ground tank, a pressure regulator valve is required on the
suction side of the pump; consult your Gasboy representative for details. The tank should be
free of water and dirt. It is recommended that the tank be pressure tested to verify it is tight.
This type of installation is not recommended for Models 9840Q and 9853QTW1M; consult
your Gasboy representative for details.
Note: The outlet fitting at the top of the float chamber should be connected to drain back to
the storage tank. The pipe size for the return line to the storage tank should be at least
3/8" (10mm).
Remote Dispenser
Locate the remote dispenser and tank with submersible pump as close to each other as possible
to attain minimum possible pressure drop and the highest possible flow rate, consistent with
the pump capacity. Consult the submersible pump manufacturer's recommendations for pipe
sizing and installation instructions pertaining to the model of submersible pump being
installed.
A Listed emergency shut-off valve (OPW 10RUS or equal) must be installed under each
remote dispenser with the shear groove at the same level as the top of the concrete island +
(plus) 1/2" (13mm). The shear valve should be rigidly supported to ensure proper shearing and
closure of the valve in the event that the remote dispenser is dislodged. According to the type
of shear valve, a different supply nipple may be required.
After a shear valve has operated on an emergency basis from fire or mechanical shock, or if it
does not operate correctly when inspected, repairs must be made before putting the remote
dispenser into service.
It is required by the Flammable and Combustible Liquids Code that a leak detector be installed
in the system to prevent underground leaks from going unnoticed.
