1. Testing
A. Place complete toilet assembly over sink or drain opening. Arrange with toilet drain valve
opening above sink or drain.
B. Connect 28 VDC Power to the toilet. See the wiring diagram (Figure 101) for connection.
C. Connect a variable pressure water source to the water inlet fitting.
D. Rinse Test
(1) Introduce the water source at 60 psi(g) to the tank. Check and ensure that solenoid valve
is open.
(2) Observe pump spray nozzle for free rotation and adequate rinsing of the toilet tank.
(3) Remove the water source, disconnect the power source.
(4) Check and ensure that the solenoid valve is closed. Check for leaks around the inlet
fitting, antisiphon valve and pump exterior.
E. Motor Pump and Timer Test
(1) Connect the pump and timer to a regulated power supply which conforms to specified
voltage and current requirements.
(2) Depress push-button switch and note toilet function. Cycle duration shall be 10+2
seconds. The swirl pattern should be consistent and vigorous, washing the complete
inner surface of the bowl.
(3) Repeat flush cycle 3 to 4 times.
