INTRODUCTION The KLE 175 GT dishwasher is designed to provide years of excellent warewash results under many types of condi-tions. Each unit is configured as an automatic start dishwasher, meaning that the dishwasher starts when the doors are closed. The dishwasher includes a three product chemical dispenser located on top of the dishwasher which dispenses liquid detergent, rinse product, and a chemical sanitizer suitable for low temperature (recommended 140 deg.)

5 F applications.) Options and additional features are also available. Contact your nearest KNIGHT representative for more details. INSTALLATION - Caution Access into electrical enclosure must be performed by authorized personnel. 1. Inspect the dishwasher upon initial receipt. Lift the door arm and open the accessory package located inside the dishwasher. Note that it includes spray arms and other equipment required for installation. 2. Examine the spot where the dishwasher is to be operated. Insure that all electrical and plumbing connections, as well as dish table placement have been considered for installation. Parameters: 3. Install leg extensions. Each leg requires 4 bolt assemblies, 1/4-20x1/2 long, to se-cure legs to dish machine.

6 Bolts are located in the accessory kit envelope and on stand. This job requires two people. Lean the machine back and install two leg extensions, lean the machine in the other direction and install the other two legs. 3/4 FPT 1-1/2 MPT 4. Install detergent, sanitizer, and rinse tubing to the peri-staltic pumps. Use the provided hose clamp ties to secure delivery tubing to squeeze tubing. Feed outlet tubing to 70 deg. elbow on side of pan directly over the sump. Tubing installation is easier if done before tabling installation. Attached to stand, remove and reinstall to attach legs 9641606 Rev: G (03/15) Page 3 of 20 Water level INITIAL OPERATION 1. Check pump intake screen for proper installation. 2. Start with all switches in the OFF position.

Turn ON the RUN POWER switch and with doors in closed position the machine will start to wash. Allow ma-chine to run through one cycle and watch machine sequence through the following wash cycle: (90 second cycle evaluated ). Machine can be adjusted to 360, 120, 90 or 72 second cycles. See below for more details. Cycle adjustments will need to be done by authorized personnel only. 1 second wash pump motor turns on 3 seconds detergent pump runs for adjusted period of time. 45 seconds drain opens and machine drains for 15 seconds.

8 Adjustable 48 to 60 seconds fresh water valve opens and rinses inside of dishwasher (drain is still open). 60 seconds drain closes and fill remains open for period of time to fill dish machine. 70 seconds sanitizer and rinse pumps run for an adjustable period of time. 70 seconds wash pump motor stops for three seconds then starts to burp the machine. 90 seconds machine will stop. This is the end of the wash cycle. 5. Machine is factory adjusted but may need to be adjusted to local water pressure to operate properly.

9 The time settings for detergent pump, fresh water fill, sanitizer pump, and rinse pump are done inside the control box using the single turn pots. The pots control the time duration of each of the listed components. Use the chart below to make settings. POT CONTROL ACTIVE TIME IN 90 SECONDS SPAN OF POT TIME ADJUSTMENT COMMENTS Detergent Pump at time = 3 seconds 2-30 seconds pot turns from 7 o'clock to 5 o'clock or 10 divisions. Each division is seconds. Pump flow is approximately ml/sec. Sani Pump at time = 70 seconds 0-15 seconds pot turns 7 o'clock to 5 o'clock or 10 divi-sions. Each division is seconds. Pump flow is approximately ml/sec. Rinse Pump at time = 70 seconds 0-15 seconds pot turns 7 o'clock to 5 o'clock or 10 divi-sions.

10 Each division is seconds. Pump flow is approximately ml/sec. Fill Start at time = 48 to 59 seconds 0-11 seconds fill start is activated during the fixed drain cycle (45 to 60 seconds) at the 7 o'clock setting time is 0 and will start fill at 48 sec-onds in cycle. At the 5 o'clock setting time is 11 seconds and will start fill at 59 seconds in cycle. Fill start is set according to water pressure and the required time to rinse de-bris down the drain. Normal setting at 20 psi flow pressure is 12 o'clock or seconds. Fill Time determined by fill start 10-42 seconds begins at the setting of the fill start. Once fill start is set the fill time determines the dura-tion of time fresh water solenoid valve re-mains open.
