2 STP isolation relays are required for all dispensers.
3 Retail electronic only: Use twisted-pair wires as specified for new
installations, or where new wires are pulled. Do not use shielded wires.
4 All wiring must be stranded with copper of specified gauge and
insulation casing.
5 All grounds must be properly connected as per the installation manual
requirements as well as state, local, and national codes.
6 Conduit must be approved for hazardous locations and properly sized
for the wiring involved. • NFPA 30A
• NFPA 70
• UL 87
• NEC
7 Properly size all circuit breakers for the units/unit options involved. NEC and local codes

9 All power wiring and circuit breakers to Gasboy equipment must be
dedicated and not shared with other equipment.
10 All circuit breakers to Gasboy equipment must be clearly labeled and
readily accessible.
11 Isolation relays must be used for dispensers to ensure that the power
is completely removed from a dispenser during service power down.
12 All pumps/dispensers must be wired to the same phase of electrical
power.
13 New site wiring must be Megger-tested. Old site wiring must be
continuity and short-tested with a digital meter. “Testing New Field

Calibration
Though all units are calibrated at the factory, all units must be checked for calibration and
recalibrated as required, before their use by customers.
Note: Units must be properly purged before calibration or calibration verification.
Incomplete purging of air can result in inaccurate calibration or errors in calibration
verification testing.
Calibration is accomplished by first pumping the product into a correctly sized prover can to
determine the accuracy of the unit. The size of the prover can is established by Weights and
Measures (W&M), depending on the flow rate of the unit.
