Operation

5. At the end of the shift and after heavy periods of accumulation, clean the

three strainer trays inside the machine.

Also, at the end of each shift, remove and clean the six spray arms. Then

reinstall them into the machine.

Also, when water becomes heavily soiled, drain the tanks and refill the

machine.

6. Check chemical buckets. Make sure there is an adequate supply of

detergent, rinse aid and (EST-66 only) sanitizer. Also, verify that the pickup

line is inserted into the correct bucket.

7. Slide in a dish rack to activate the cycle start trip switch on the pre-wash end

of the machine. The 60-second time-delay-off relay will hold the machine in

the run mode for 60 seconds after a rack releases the cycle start switch and

then shut off. This time-delay relay prevents the machine from continuing to

run when a dish rack is not in the machine.

3.2.1. Chemical Dispensing

This machine must be operated with an automatic detergent feeder and automatic chemical

sanitizer feeder, including a visual means to verify that detergents and sanitizers are delivered or

a visual or audible alarm to signal if detergents and sanitizers are not available for delivery to the

respective washing and sanitizing systems. Please see instructions for electrical and plumbing

connections located in this manual and in the feeder equipment manual.

The rinse and sanitizing agents are not injected during the initial fill stage. They are injected into

the final rinse make-up water when the final rinse trip switch is activated in the final rinse tank.
