Notes:
1 All wiring and conduit runs must conform with all building/fire codes, all Federal, State, and
Local codes, National Electrical Code, (NFPA 70), NFPA 30, and Automotive and Marine
Service Station Code (NFPA 30A) codes and regulations. Canadian users must also comply
with the Canadian Electrical Code.
2 Pump motor can be wired as 230 VAC to reduce current draw. See breakaway view of 230
VAC WIRING. All other wiring should remain the same except for the addition of the L2
(requires 230 VAC breaker for control). If connected to equipment requiring control of the
authorization input, the Phase 2 Feed should be switched through a separate relay to prevent
false triggering of the authorization signal.
CAUTION CAUTION
To avoid damage to the CPU PC board, all unused wires must be individually capped,
and before applying power, you must verify that the RESET COMPLETE and FAST
FLOW wires are not shorted to conduit or chassis.
3 RESET COMPLETE (switch detect) line can supply 170 mA AC maximum for connecting to
fuel management system circuitry.
4 FAST FLOW line can supply 170 mA AC maximum for remote control or monitoring of the
fast flow valve found in the pump.
5 If the CONTROL/PUMP MOTOR FEED line is controlled by a fuel management system
using solid state relays, a resistor assembly must be installed between the Control Feed line
and Feed Neutral to prevent false triggering of the authorization input. The resistor assembly is
8.2K OHM, 10 Watt (P/N C05818) for 115/230 VAC domestic and 30K OHM, 10 Watt (P/N
C06683) for 230 VAC international wiring.
6 When used with an aboveground tank, the anti-siphon valve mounted on the tank must be
driven from the EXTERNAL VALVE line, have the same operating voltage as the pump
motor, and the current draw must not exceed 1 Amp. If these conditions are not met, it must be
controlled by an external relay driven from the EXTERNAL VALVE line. DO NOT connect
the anti-siphon valve or external relay to the RESET COMPLETE line. DO NOT connect two
or more EXTERNAL VALVE lines together. If more than one pump is drawing from the tank,
separate anti-siphon valves must be installed, or each EXTERNAL VALVE line must operate
an external relay which then operates the valve.
7 Use the wire size chart listed on page 5-4 when determining the wire size for the control
wiring.
8 If this unit is equipped for 230 VAC operation (international), wire as shown in the standard
115 VAC wiring layout diagram.If this unit is equipped with a TopKAT option, there will be
10 wires in the junction box. See The TopKAT Installation Manual for wiring requirements
and information.
9 Model 9853QTW1M should not be used with aboveground tanks.
