GETTING STARTED
Introduction to EAH and EC
CMA dishwashers have been used world wide for many years. This manual has been written to help you, the
operator, in your job. Your job is one of the “most important” in this restaurant. Why? Your product, the dishes
and glasses, is the first thing the customer notices when he sits down. Clean, sparkling dishes and silverware will
set the mood for the customer when he observes the table setting.
Receiving and Installation
The dishwasher is shipped from the factory bubble packed on a pallet. The guidelines are listed in a step-by-step
procedure for your reference.
1.
Packaging
Unwrap the machine and check for the following component parts:
Scrap accumulator complete with lid and scrap tray. This is normally an integral part of the
machine
Tube stiffeners. Tube stiffeners must be used to prevent the feed tubes from curling inside the
chemical pail and sucking air. These are pre-installed to the chemical pump and attached to the
back of the dishmachine. The ends of the chemical tubing have been flared so that the tubing will
not pull out of the stiffener. Red is for detergent, white for sanitizer, and blue for rinse aid.
2.
Plumbing
The machine needs the following:
2” pipe for the drain outlet
½” pipe for the incoming water
A flex hose or quick disconnect union. The water inlet is at the top left corner of the dishwasher
3.
Electrical
The machine is 110 volt. The master switch is at the top left side of the control box.
4.
Chemical Feeder
The peristaltic pumps are assembled and included within the machine.
5.
Scrap Trap Accumulator
The scrap trap accumulator is designed to perform two basic functions:
It allows a method to discharge all the heavy solids out of the machine with each wash and rinse
cycle.
It provides capacity to drain the contents of one cycle regardless of the ability of the existing drain
to accept the discharge rate.
There is a drain connection sleeve (2”) on the bottom of the scrap accumulator (See drain connection
instruction).
CMA standard dishwashers operate on 110 volts. Other voltage requirements are available on request.
When installing the single rack units, either model EAH or EC, it is recommended that a clean 20 amp
circuit be provided to the machine.

Water Line
6.
The model EAH & EC should plumbed with ½” hot water line. The time necessary to deliver water to
the machine is controlled by the number four cam. This cam provides the serviceman with the
opportunity to fine-tune the machine to deliver the proper amount with each cycle. Refer to the service
manual for an in depth discussion of this procedure.
7.
Activating Machine
The machine is equipped with a prime switch to activate the peristaltic pump at any time the master
switch is “ON”.
Following the completion of the installation, always fill the machine with water before the machine is
started.
Hold the fill button until the water level is approximately ½” to ¾” below the overflow hole in the
PVC standpipe. This water level should be approximately even with the bottom edge splash guard
in sump area of machine.
Activate the prime switches for the three chemical pumps until the product is discharging into the
sump.
To start the machine, close the doors and the machine will cycle automatically.
The amount of product delivered by each cam is controlled by changing the opening in each cam. When
the micro switch rides down into the cam, the peristaltic pump motor begins to rotate. It will continue to
rotate until it rides up out of the groove. Therefore, to extend the amount of product delivered to the
machine, open the groove. To reduce the amount of product delivered to the machine, close the groove.
Cams are slip fit. A cam adjustment wrench is provided, but the cam can be adjusted with a small
screwdriver or the edge of a table knife.
Technical personnel are available during normal b usiness hours should you, as an installer, have any
questions. We are available to serve you at 800-854-641 7.
