OPERATION

NOTE:

The machine may be stopped at any time by opening the door. When restarted, the cycle does not start over. It will continue from the point at which it was interrupted.

7.Check the rinse temperature during the final rinse (120 seconds into cycle). The rinse temperature must be 82°C/180°F minimum for models 501HT, 501HTN, 501UT and 501UTLC and 60°C/140°F for models 501LT and 501UTL.

8.The pump will automatically stop and the green cycle light will turn off indicating the cycle is completed.

9.Open the door and remove the rack.

10.Repeat steps 4-9 for additional cycles. Machine operation is automatic.

11.CLEAN the scrap screen after every meal period. During heavy usage, the scrap screen should be cleaned more frequently.

!CAUTION:

Poor machine performance and/or damage to the machine can occur if the scrap screen becomes clogged with soil or waste particles.

12.After completing usage for the day, water in the tank should be drained by depressing the OFF/DRAIN switch and closing and latching the door. This initiates a 100 second wash and drain cycle that drains the tank.

!CAUTION:

DO NOT LEAVE WATER IN THE TANK OVERNIGHT. Water left in the tank overnight will allow harmful chemicals to deteriorate the tank.

Extended Wash Cycle

On models 501HT, 501HTN, 501UT and 501UTLC, but not on models 501LT and 501UTL, an extended wash cycle is available for pots, pans and heavily soiled items.

To use the Extended Wash Cycle:

1.Insert the loaded rack into the machine. Close the door and depress the latch. Wait 10 seconds for the detergent to be dispensed automatically.

2.Flip the Extended Wash/Delime Switch to the UP position. The green cycle light will go out, indicating that the machine is in a CONTINUOUS wash mode.

3.When your desired wash time has passed, flip the Extended Wash/Delime Switch to the DOWN position. The green cycle light will come on, indicating a return to the normal wash mode. The machine will now complete the remaining portion of the automatic cycle.
