Installation
Water Connections
1. All models have a 6 ft. exible hot water ll hose with a 3/4" GHT connector.
2. A 1/2" or larger main incoming supply line should be installed to the dishwasher.
3. A 1/2" or larger shut-off valve should be installed in the water supply line as close to the
dishwasher as possible for service.
4. The hot water supply must provide a minimum of 140°F/60°C, measured at the dishwasher for
the 40°F/ 22°C rise booster.
5. For the 70°F/39°C rise booster the hot water supply must provide a minimum of 110°F/43°C
measured at the dishwasher.
Note
Plumbing connections must comply with national, local plumbing and sanitary codes.
IMPORTANT
Make sure that the exible water supply and drain hoses are not kinked.

5
Installation
1. The dishwasher has a 6ft. 3/4" I.D. drain hose. The maximum drain height
connection must not exceed 3 ft.[9 m].
The recommended drain height is 17" [.4 m] or less above the oor.
2. The drain hose is secured to the rear of the machine by a clamp to maintain a
goose-neck bend in the drain hose.
DO NOT REMOVE THE DRAIN HOSE RETAINING CLAMP.
DO NOT STRETCH THE DRAIN HOSE.
3. A 3/4" hose barb tting is strapped to the drain hose to use in connecting the
drain hose to building drain line.
The service part number for the
hose barb is P/N 0512321.
4. Install the drain hose to a "WYE" drain tting. Connection to a "TEE" tting will
prevent the dishwasher from draining completely.
5. The maximum drain ow is 8 U.S. gpm/7 Imp. gpm/30 L.P.M.
6. Make sure the drain hose does not kink. Kinks will prevent the dishwasher
from draining completely, and the dishwasher will overow out the front door.
NOTE: DO NOT CONNECT THE DRAIN HOSE TO A DISPOSER.
THE DISHWASHER WILL NOT DRAIN CORRECTLY.
Drain Connections
ATTENTION
Do not connect the drain hose to a disposer. The dishwasher will not drain correctly.
The dishwasher flexible drain hose
must be connected to a WYE fitting. Do not connect the dishwasher
flexible drain hose to a TEE fitting.

Adjusting the Chemical Dispenser Pumps
The amount of detergent and rinse-aid that are dispensed during the dishwasher cycle are controlled by
adjustable cams on the timer assembly. Variables such as the type of chemicals used and the hardness
of the water supply often require that the timer cam settings must be changed. It is recommended that
the chemical supplier make these adjustments.
(Refer to the illustration below).
Note:
Only the Detergent and the Rinse-aid cams are adjustable. Do not attempt to adjust any other timer cam.
To adjust the chemical dispensing pump timer cams:

The pressure and temperature gauges are located on the lower-left corner
of the lower-front access panel.
ATTENTION
At the beginning of the day, run 2 empty cycles before checking the final rinse
operating temperature. The first cycle will take longer than normal because the
water temperature in the booster is low.

14
Extended Wash Mode
The Extended Wash Mode is used to wash heavily soiled items such as pots, pans and other wares that
require more washing time than the standard 100-second Normal Wash Mode.
The dishwasher will remain in the Extended Wash Mode until the operator exits the mode.
1. Load a dish rack into the dishwasher, close the door.
2. Press and hold the START button for 1-second then release.
3. The green in-cycle light will illuminate and the dishwasher will begin a normal wash cycle.
4. Press the EXT WASH button to place the dishwasher in the Extended Wash Mode.
5. The green extended wash light will illuminate indicating that the machine is in the
Extended Wash Mode.
6. The dishwasher will continue to wash until the operator presses the EXT WASH button again.
7. Press the EXT WASH button. The green extended wash light will go out indicating that
the dishwasher has returned to the Normal Wash Mode.
8. The dishwasher will nish the wash cycle and perform a nal rinse of the wares.
Operation
The nal rinse water temperature must be a minimum of 180ºF/82ºC during the final rinse cycle to ensure that all
wares are sanitized. If for any reason, the hot water temperature in the booster tank cannot provide this temperature,
the dishwasher will enter a Safe-T-Temp Mode of operation and extend the cycle time.
The Safe-T-Temp changes the Normal Operation Mode as described below:
1. The Safe-T-Temp constantly monitors the water temperature inside nal rinse booster.
2. If the temperature inside the booster heater falls below 180ºF/82ºC then the Safe-T-Temp
will extend the wash cycle time until the booster heater water temperature reaches the proper
temperature.
3. The in-cycle light will remain illuminated during the Safe-T-Temp Mode.
4. The RINSE water temperature gauge must be monitored to ensure that a minimum of
180ºF/82ºC is maintained during the rinse cycle.
5. The temperature range for the final rinse water is180-195ºF/82-91ºC.
6. An extraordinarily long wash cycle may indicate a low incoming water temperature or a
problem with the booster heater operation.
DO NOT REMOVE WARES UNTIL THE FINAL RINSE CYCLE HAS
SANITIZED THE WARES AND THE GREEN CYCLE LIGHT GOES OUT.
Safe-T-Temp Mode
Normal Wash Mode (continued)
11. Opening the door when the dishwasher is in-cycle will stop the dishwasher. The cycle will resume
automatically when the dishwasher door is closed fully.
12. The nal rinse cycle begins at the end of the wash cycle and runs for approximately 15-seconds Check the
RINSE temperature gauge during the nal rinse and make sure that it indicates a minimum of 180ºF/82ºC.
The acceptable range of operation is180-195ºF/82-91ºC.
13. At the end of the rinse cycle, the in-cycle light will go out. Open the door and remove the clean
rack of wares. Repeat steps 8-12 for additional dish racks.
14. Refer to the Cleaning Instructions, "After Each Meal Period or every 8 Hours of Operation", on
page 15 for the procedures to drain and clean the dishwasher.
