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.
