INSTALLATION
2.10.2 Models UH-100B, UH-100
Chemical discharge tubes were installed at the factory and stowed in the base of the machine.
Installation of the optional detergent pump and/or the rinse aid pump requires mounting
the pump, connecting all tubing to the pump(s) and making the electrical connections.
WARNING:
When working on the dishwasher, disconnect the electric service and place a red tag at
the disconnect switch to indicate work is being done on that circuit.
Refer to Fig. 2.10.3 at right.
The illustration shows the typical
installation of the detergent and
rinse aid pumps. Pump kits contain
the necessary parts for field installation
and are available from your authorized
Champion parts supplier.
• The detergent pump is a peristaltic
pump enclosed in a black housing.
• The rinse aid pump is a peristaltic
pump enclosed in a black housing.
To install the detergent pump:
1. Remove the lower front access panel.
2. Mount the pump on the machine base with two screws.
3. Route the detergent pick-up tube and tubing out the rear of
the machine through the access hole located above and
between the fill and drain hoses.
4. Connect the supply and discharge tubing to the pump.
Pump rotation is clockwise. The supply tube connects on the
left side of the pump; the discharge tubing connects on the right
side of the pump.
5. Chemical discharge tubing runs to the fill chute assembly
located on the left side of the machine.
