Wiring Diagrams
Figure 5-17: Wiring Diagram: 9852TW2, 9853TW2, 9853TW1M Pumps
Diagrams shown are for Q Model pumps. If your pump is an A model, DC junction box will be separate.
Notes:
1. The power resistor assembly is 8.2K OHM, 10W (P/N C05818) for 115/230 VAC domestic units and 30K OHM, 10W (P/
N C06683) for 230 VAC international units.
2. Before applying power, the TopKAT Pump Control PCB jumpers must be set for electronic pulser as shown in
Block ID" on page
34. Failure to properly set the jumpers will damage the TopKAT.
3. Wire colors shown reflect current production since June 1998. If your 9800 is older than June 1998, your wire colors
may vary.
4. 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.
