8 – Pump/Dispenser Manual Test
Verify General Guidelines
Verify if the general guidelines listed below were met when installing the system’s pumps and
dispensers. If your system contains any electronic pumps, follow the appropriate installation
manual for applicable tests.
SUCs
The CFN System is capable of directly driving pump motors up to 3/4 HP at 120/240 VAC or
1-1/2 HP at 240 VAC. A starter relay must be used with pump motors exceeding these
limitations. A separate circuit breaker should be supplied for each pump to meet the current
requirements and to allow for isolated control with the circuit breaker panel in case of
problems.
Dispensers
The CFN System is capable of directly driving SUBs up to 3/4 HP at 120/240 VAC or 1-1/2
HP at 240 VAC. A dispenser with a SUB exceeding these limitations will require the use of a
submersible starter relay. A separate circuit breaker should be supplied for each dispenser in
cases where it will directly drive the SUB. Dispensers may be grouped together on a single
breaker when the SUB has its own breaker. It is recommended that no more than two
dispensers be powered from one breaker to maintain isolated control with the circuit breaker
panel in case of problems.
Manual Override Test
The pumps and/or dispensers should be tested to verify AC wiring. The steps below indicate
the proper procedure for testing and the expected results. If any of these tests fail, correct the
wiring and perform the test again. See
Figure 6-3 on page 41 for the location of the override
switches.
Power up only the PCU(s) during these tests!
