14. DO NOT use the GASBOY fuel dispensing equipment to remove water ballast from the
storage tank.
15. DO NOT use gaskets on covers of explosion-proof type boxes. The sealing compound found
around wires at various locations within conduit is a requirement of the National Electrical
Code and should not be disturbed. Ensure that the mating surfaces between the junction box
and cover are free of dirt, debris, nicks and scratches. Tighten junction box covers before
replacing panels.
16. DO NOT use knock-out boxes or flexible conduit for installing this unit. All power and lighting
wires should be run in threaded, rigid, metal conduit. All threaded connections must be
drawn up tight with five (5) threads minimum engagement. Only one opening in the AC
junction box is provided with a plug at the factory. At completion of the installation, it is the
installer’s responsibility to ensure that any unused openings are plugged.
FOUNDATION
Make sure that your installation conforms to the applicable codes required by Federal, State, and
local agencies concerning secondary containment underneath the dispenser. Follow the
installation requirements of the secondary containment manufacturer to ensure that your site is
environmentally safe and to minimize the entrance of water under the dispenser.
Secure the pump/remote dispenser to the island using anchor bolts through the two mounting
holes, which are 13 inches (330mm) apart and are indicated on each base layout. If the
dispensing unit is not securely fastened to the island, supply line leaks at unions and pipe joints
may occur. Use one of two types of bolts to anchor the pump to the island. Use two (2) 1/2" x 5"
(13mm x 125mm) machine bolts imbedded in the concrete, or, to meet minimum UL and API
requirements for universal interchangability of pumps, use two 1/2" x 3 1/2" (13mm x 90mm) lag
screws with 2" (51mm) expansion shields.
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 (3.66m) for gasoline and 13
feet (3.96m) 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.
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"
(9.525mm).
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.
