Getting Started

2. Getting Started

2.1. Introduction to the EST

The EST Dishmachine is safe and easy to operate with its “Auto Start/Stop” and it’s economical
to operate—using only 1.25 gallons of water per cycle and less than 1900 watts of power when
running. The EST Dishmachine’s top mounted controls include built-in chemical pumps and a
deliming system that assures proper chemical usage. Its integrated scrap tray prevents food soil
from entering the drain system. The EST can be run at a rate of 37 racks/148 covers per hour
and its heavy-duty stainless steel construction assures long life and years of trouble free
operation.

The EST is available for straight or corner applications.
This manual is structured to provide a complete reference guide to the EST Dishmachine. It is

presented in a manner that all users will be able to comprehend and use as an effective tool in
supporting the operation and maintenance of the dishmachine. The first section explains how the
machine is packaged and what to look for when receiving the machine.

After unpacking the machine, this manual explains how to install and set up the machine for use.
Requirements are given for plumbing, wiring, and space considerations. These attributes of the

machine are always taken into consideration by our well-trained sales representatives prior to the
order being placed. In the manual, guidance is also given for installation to ensure that the

machine will be able to run at optimum conditions.
The Operation section of the manual may be used for instruction and procedures when required.

We make this portion of the manual easy to understand so that all levels of operators may be
able to read and comprehend the operation of the machine. The function of the machine itself is
mostly automatic and takes little training to put into full operation. The Operation section also
includes diagnostic considerations (troubleshooting) for the machine when problems occur.

The remaining sections of the manual—Parts Manual and Electrical Diagram—have the parts
lists with exploded view drawings and the wiring diagram for the machine.

CMA warranties the workmanship of the machine.
We are committed to providing the best machines and customer service in the food industry and

your feedback is welcome.
