INTRODUCTION

The KLE 175 GT dishwasher is designed to provide years of excellent warewash results under many types of
conditions. 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. 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:

Electrical Water line Drain line

- 120V 20 AMP circuit or

- 240V 10 AMP circuit (not field

20 psi flow pressure 140 deg. F
3/4” FPT on machine

1-1/2” MPT on scrap accumulator

convertible)

3. Install leg extensions. Each leg requires 4 bolt assemblies, 1/4-20x1/2” long, to se­cure legs to dish machine. 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.

4. Install detergent, sanitizer, and rinse tubing to the peri­staltic 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.

5. Place the dishwasher at the spot desired for
normal operation. Level the dishwasher using
adjustable bullet feet at the bottom of the legs.
Install spray arms included in the accessory box.

6. Connect hot water supply line to the 3/4 FPT
line strainer at rear of machine. Ensure that wa­ter pressure is sufficient for fill (approx. 10

3/4 FPT

GPM flow @ 20 psi.). Connect drain to 1-1/2”
MPT nipple on scrap accumulator.

7. Make electrical connections (refer to data plate for voltage and current ratings)
to the labeled barrier provided at the inside back of the control box. Run all elec­trical wire through suitable conduit and insure all connections are made in accor­dance with local wiring codes. It is recommended that the circuit breaker carrying
the dishwasher load have NO OTHER ELECTRICAL DEVICES connected.

1-1/2 MPT

8. Attach prewash and drying tables to the dishwasher, insuring that sufficient
space is provided for the dishwasher operator. Insure that adjustable legs on
prewash and drying tables have been adjusted for proper drainage of water.

INLINE OR CORNER DOOR CONVERSION

Conversion from inline to corner can be done by changing the location o f the tray stop on the tray rails and install­ing door conversion bracket and screws in the accessory kit. Two 7/16 wrenches will be needed to make the con­version.
Conversion of the machine is easier
if done before tabling is attached.
Machines are factory set in the
inline configuration.

1. Remove the two (A) bolts/nuts
securing the tray rail stop located
on the tray rail and reposition to

A

desired configuration.

2. Make sure sump screen is in place over the pump
intake tube so no parts fall in to the pump! Remove
the two knockouts on the front door. One is located in
the center and the other is directly below the right
side door stop bumper. Remove one knockout directly
below bumper on right side door.
