It is recommended to conduct this sequence check in the auto fill cycle after draining the wash tank and booster tank. See “II.C. Sequence of Operation” for further details.

1)Use the “ON/OFF” button on the operation panel to turn off the unit.

2)Pull out the overflow pipe to drain the wash tank.

3)Drain the booster tank through the drain hose.

4)Replace the overflow pipe and drain hose in their correct positions.

5)Enter the switch open/closed display mode according to the above procedure.

6)Auto Fill Cycle

a.After the service panel is closed and the “ON/OFF” button is pressed, the inlet water valve in the booster tank opens in 10 seconds to start water supply.

b.After a while, the booster tank water level float switch closes, segment C in the display comes on, and the inlet water valve closes to stop water supply.

c.The rinse pump starts to feed water to the wash tank. When the booster tank water level goes down, the water level float switch opens, segment C in the display goes off, and the inlet water valve opens to start water supply.

d.After the rinse pump is energized for a preset time to fill the wash tank, the wash tank water level sensor closes, and segment E in the display comes on.

e.In normal operation, the booster tank backup water level float switch does not close, and segment A in the display stays off. If the booster tank water level float switch fails or the booster tank water level reaches the overflow level, segment A comes on.

7)Wash Cycle/Rinse Cycle

a.When a rack is loaded from the wash compartment entrance and the wash start switch closes, segment B in the display comes on and the wash pump starts the wash cycle for a preset time. When the conveyor moves the rack forward and the wash start switch opens, segment B goes off and the wash pump stops after the preset time. Segment E in the display stays on.

b.If the booster tank is below the predetermined water level, segment C in the display stays off. The inlet water valve stays open until segment C comes on.

c.When the wash cycle ends and the rinse start switch closes, segment D in the display comes on and the rinse pump starts the rinse cycle for a preset time. When the rinse start switch opens, segment D goes off and the rinse pump stops after the preset time. When the rinse cycle starts, the booster tank water level goes down and segment C in the display goes off. The inlet water valve stays open until segment C comes on.

Diagnosis: If any problem is found by the above sequence check, refer to “III.B. Error Codes,” “III.C. Service Flow Charts,” “III.D. Float Switch Check and Cleaning” and “III.E. Thermistor Check.”
