Installation procedure
1. Turn off the power going to the dishwasher from the breaker panel
2. Remove the lower front & rear panels of the dishwashers, as per the "instruction &
maintenance manual" provided with the dishwasher.
3. Current models have a factory pre-drilled hole in the back. Remove the stainless
steel nut & bolt and insert the detergent injector fitting. Otherwise, drill a 15/32"
(12mm) hole in the back of the dishwasher tank, as per the illustration. Exact
location of the hole is not critical. However, you must ensure that the location of
the fitting will not interfere with the turning of the upper wash arm and also that
the fitting will be above the level of the dishracks in the wash tank.
4. Install the detergent injector fitting in the hole and secure the nut inside the wash tank
5. Slide one end of the vinyl tubing on to the detergent inje ctor-fitting valve and secure with the hose clamp provided. Route the free
end of the tubing into the base of the dishwasher and out the front, ensuring that areas of high heat such as the booster tank and the
pump motor are avoided.
6. Cut the vinyl tubing to the required length at the front of the dishwasher (leaving sufficient slack) and connect the free end to the
peristaltic pump outlet fitting. Inlet & outlet are identified on the pump by arrows.
7. Connect one end of the loose piece of tubing to t he inlet fitting of the pump.
8. Secure the mounting bracket (with pump) to the screw studs under the wash tank with the 5mm Hex Nuts provided. Secure the
peristaltic pump to the "L" shaped bracket with the 4mm screws, lock washers & 2 nuts provided.
9. Connect the two electrical leads from the peristaltic pump to the wiring harness in the dishwasher.
10. Route the free end of the vinyl tubing out the bottom of the dishwasher, again ensuring that areas of high heat such as the booster
tank and the pump motor are avoided. Connect the tubing to the filter with check valve.
11. Replace the lower front & rear panels of the dishwasher.
OPERATION OF THE LIQUID DETERGENT PUMP
The pump will operate automatically during the washing/rinse cycle. The pump operates whenever the water fill valve is open: during
the fill cycle and during the rinse cycle, remember that the detergent is being injected into the wash tank and is not mixing with the
fresh water from the booster that rinse the dishes. There is an adjustment screw on the pump to regulate the amount of detergent being
injected during each cycle.
