The KLE 150 GT dishwasher is designed to provide years of excellent warewash results under many types of conditions. This unit is configured as a push button start dishwasher. The dishwasher includes a three product chemical dispenser 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. Open the door and locate the accessory package inside the dishwasher. Note that it includes a spray arm and other equipment required for installation.

2.Examine the spot where the dishwasher is to be operated. Insure that all electrical and plumbing connections have been considered for installation Parameters:

	sure that water pressure is sufficient for fill
	(approx. 10 GPM flow @ 20 psi.). Connect
	drain to 1-1/2” MPT nipple on scrap accu-
	mulator to the lower right.
	6.	Make electrical connections (refer to	3/4 FPT
	data plate for voltage and current ratings)		1-1/2 MPT
	to the stationary conduit box located on the
	stand tray behind electrical box. Remove
	cover from stationary conduit box and
	make connections (use appropriate wire

			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 debris down
			the drain. Normal setting at 20 psi flow pressure is 12
			o'clock or 5.5 seconds.
Fill Time	determined by fill start	10-42 seconds	begins at the setting of the fill start. Once fill start is
