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
When constructing the pump island for the dispensing equipment, be sure to extend the island
excavation beyond the depth of the frost line. Leave open an area from the inside edge of the
unit's base as shown on the specific base layout. Unless required by local regulations, do not
cement the pipes and conduits into the island. The open area within the base will provide access
for future servicing of the fittings, check valve and conduit assemblies. Fill in the boxed-in
section with dry sand to keep condensation in the pump housing to a minimum and to help
prevent fogging of the totalizer window.
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 by an X. 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).
