½” female NPT
conduit connection
for AC wiring
2.2.2. Shelf Installation on Aboveground Storage Tank
•
The Wayne 700 Series may be mounted on a shelf on the side of the tank to make the
user controls more accessible with larger tanks.
•
The installer must provide the necessary mounting hardware, piping, and safety valves
according to the federal, state, and local codes.
•
If the pump is mounted below the product level, it is necessary to install an emergency
gate valve in the piping immediately after it exits the tank followed by a solenoid valve
controlled by the pump’s auxiliary AC control lead (see Section 2.3.4). A pressure
regulator valve with shear section, or equivalent valve, must be installed beneath the
pump. All valves must be equipped with a pressure relief mechanism. Pressure in the
pump cannot exceed 50 psi.
2.3. Electrical
Wiring
2.3.1. General
•
Wayne recommends employing a qualified electrician for all wiring.
•
A hazardous liquid is being handled, so it is important to ensure that all wiring and
conduit is in accordance with all federal, state and local regulations, including, but not
limited to, the National Electrical Code (NFPA 70), NFPA 30, NFPA 30A, and NFPA
395.
2.3.2. Circuit Breakers & Cutoff Switch
•
Wire the pump to a dedicated 15 AMP circuit breaker.
•
Two pumps may be wired to the same circuit breaker.
•
In addition to the circuit breaker requirements, an emergency power cutoff should be
installed that provides a single control to simultaneously turn off all AC power to all of
the site dispensing equipment. The switch should be located within a convenient distance
of the fueling equipment.
2.3.3. Conduit:
•
Use ½” threaded, rigid, metal conduit and properly
sealed connectors.
•
All threaded connections must be drawn up tight and
have a minimum of five threads engaged.
•
Do not use flexible conduit or knockout boxes.
