11. DO NOT use power line wiring of inadequate capacity. (Use gauge specified by the wiring
diagram or wire chart provided in Section 3).
12. DO NOT use a circuit breaker of improper size. (See Section 3).
13. DO NOT install fill pipe to tank where it can be submerged with standing water.
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
mating surfaces between the box and cover are
free of dirt, 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 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 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/dispenser to the island using anchor bolts through the two mounting holes,
which 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) long machine bolts
imbedded in the concrete, or, to meet minimum UL and API requirements for universal
interchangeability of pumps, use two 1/2" x 3 1/2" (13mm x 90mm) long lag screws with 2" (51mm)
long expansion shields.
The drawing on the following page, Installation Layout, illustrates a recommended installation of
the Model 552A & 553A power pump. In selecting a location for the pump and tank, bear in mind
that a suction pump will draw liquid horizontally up to 100 feet, but on a vertical lift it is not
advisable to exceed 12 feet (3.6m) for gasoline, or 13 feet (4m) for diesel.
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 (3.6m) for gasoline and 13
feet (4m) for diesel and can vary according to conditions of the installation and fuel temperature.
