Turn off the power and water supply to the booster water inlet.
21. Before proceeding provide a method of draining about 3.5 gallons of water from
the tank. Now drain the water from the booster heater. Loosening a connection
at the booster water inlet will aid in draining.

the two wire nut screws and separate the wires. Unscrew and remove the green
ground wire.
23. Remove the pump’s electrical strain relief using needle nose pliers.
24. Remove upper screw on the Power supply bracket and bend forward to help
access pump flange bolts.
25. Using a 5/8” wrench remove the four bolts from the two pump flanges. Remove
the pump.
26. Install the new pump using the new flange o-ring seals provided with the
replacement pump and reinstall the four bolts.
27. Open the new pump electrical cover by removing the one cover screw. Use the
wire nut screws to attach the black supply lead to the bottom wire in the pump
and the white supply lead to the top wire in the pump. The green ground wire
attaches to the ground screw.
28. Re-install the pump electrical cover.
29. Turn water ON and open the booster outlet to fill the booster and remove air.
Also, check for water leaks. Run 2-3 racks through dish machine with power off
