Figure 7-17: 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 8.2 kilo-ohm, 10 W (part number C05818) for 115/230 VAC domestic units and 30 kilo-
ohm, 10 W (part number 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 “Terminal
Block ID” on page 42 . Failure to properly set the jumpers will damage the TopKAT.
3. The wire colors may vary. Refer to current pump wiring diagrams.
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.
