5.After a 2-3 second pause, the pump drain cycle begins and continues for approximately 30 seconds.
6.After a 2-3 second pause, the fill valve opens, and the pump starts for the rinse cycle.
7.Within approximately 25 seconds, the rinse cycle is complete. The pump stops, the green cycle lamp turns off, and the cycle is complete.
8.Open the door and remove the rack of clean ware. The door must remain open for 5 seconds to allow the timer to reset before starting another cycle.
Operation Procedures
The operation of your dishwasher will be more efficient when these procedures are followed:
1.Check that the spray arms and scrap screen are in place.
2.Close the door and depress the front edge of the door latch toward the door. Push the ON/FILL switch to the ON position. The tank will begin filling with water. This procedure is followed only when the tank is empty.
3.When the tank is full, check the wash tank temperature gauge. Minimum wash temperatures are:
•UH-150B, UH-150 – 150°F/66°C.
•UL-150 – 140°F/60°C.
4.Scrap and preflush all items to be washed, and load the items into the rack. DO NOT OVERLOAD the rack. Wash only one layer of silverware in a rack.
5.Open the door and insert the rack into the machine.
6.Shut the door, and depress the door latch. This will start the wash cycle. The green cycle lamp located on the front control panel will light. This lamp will remain on until the entire wash and rinse cycle is completed.
8
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 180°F/82°C minimum for models UH-150B, UH-150, and 140°F/60°C for model UL-150.
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 UH-150B, UH-150, but not on model UL-150, 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.

MAINTENANCE
MAINTENANCE
The efficiency and life of your machine is increased by regularly scheduled preventive maintenance. A well maintained machine gives better results and service. An investment of a few minutes of daily maintenance will be worthwhile.
The best maintenance you can provide is to keep your machine clean. Components that are not regularly cleaned and flushed will clog and become inoperative.
Intervals shown in the following schedules represent an average length of time between necessary maintenance. Maintenance intervals should be shortened whenever your machine is faced with abnormal working conditions, hard water, or multiple shift operations.
Cleaning Schedule
•Daily – Every 8 Hours
1.Depress the OFF/DRAIN switch to OFF and close and latch the door to drain the tank.
2.Open the door and remove both the upper and lower spray arms by unscrewing the knurled fastener holding each spray arm.
3.Remove the scrap screen carefully to keep soil or waste particles from falling into the sump.
4.Clean inside the tank with clean water. Backflush the scrap screen until it is clean. Do not strike the screen against solid objects.
5.Clean the wash arms to remove any debris from spray openings. Do not strike the spray arms against solid objects.
6.Reinstall the scrap screen and spray arms.
7.Leave the door open overnight to allow drying.
8.Report any unusual conditions to your supervisor.
•Meal Periods
1.Clean the scrap screen after every meal period and more frequently during heavy usage. Do not allow the scrap screen to become clogged with soil or waste particles.
10
MAINTENANCE
Deliming
Your dishwasher should be delimed regularly as required. This will depend on the mineral content of your water.
Inspect your machine interior for lime deposits. If deliming is required, a deliming agent should be used for best results.
If you have the chemical sanitizing model (UL-150), carefully follow the following procedure before deliming:
DANGER:
!Deliming solution or other acids must not come in contact with household bleach (sodium hypochlorite) or any chemicals containing chlorine, iodine, bromine, or fluorine. Mixing will cause hazardous gases to form. Skin contact with deliming solutions can cause severe irritation and possible chemical burns. Consult your chemical supplier for specific safety precautions.
1.Remove the sanitizer tube from the container. Place the tube into a container of hot water.
2.Depress and hold the SANITIZER prime switch (located on the front panel) until clear water enters the tank through the fill air gap.
3.Close the door and depress the door latch. Complete two operating cycles to purge the machine of all sanitizer.
Deliming Process
Complete the following procedure to delime your machine:
1.Add the delime chemical to wash the tank (per chemical supplier specifications).
2.Close and latch the door.
3.On models UH-150B and UH-150, depress the EXTENDED WASH/DELIME switch on the front panel as soon as the cycle starts. On model UTL, proceed to step 5 of this procedure.
NOTE:
The EXTENDED wash/delime switch will operate only during the wash cycle. When this switch is in the ON position, the machine stays in the wash cycle until the switch is OFF. After switching to OFF, the machine will finish the cycle.
4.After 2-1/2 to 3 minutes (or as long as required), turn off the EXTENDED WASH/ DELIME switch. The machine will finish a complete cycle.
5.Complete two cycles with the machine empty to purge the machine of all delime chemicals.
6.Deliming is complete.
