Cma est-ah Owner's Manual

Operation  

All machines are equipped with switches to prime the peristaltic pumps at anytime the master 
switch is "ON". 

Following completion of the installation, always fill the machine with water before starting the 
machine. 

1.  With the power “ON” hold the fill button until the water level overflows into the scrap 

accumulator. 

2.  Check the chemical lines to the chemical containers. 

a.  Red: detergent line. 

b.  Blue: rinse agent line. 

c.  Clear/White: sanitizers destainer line. 

3.  Activate the prime switches for the three chemical pumps until product is 

discharging into the machine. 

4.  To start the machine, close the doors - this will automatically start the machine.  The 

machine will run through its cycle. 

5.  Operate the machine one cycle and watch to ensure that the chemicals are 

delivered and stop during the cycle.  Remember:  red tube - detergent: blue tube - 
rinse: and clear/white tube - sanitizer.  Check temperature at the end of the cycle for 
140

°F, 60°C. 

The amount of product delivered by each cam is controlled by adjusting the cam’s 
opening.  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 
grove; to reduce the amount of product delivered to the machine, close the groove.  
The cams are slip fit and a cam adjustment wrench is provided. 

CAUTION:  The motors on the new peristaltic pumps may be stalled by excessive tightening of 
the cover plate screws.  If a peristaltic pump does not turn when the micro switch is activated, 
loosen the screws on the cover plate. 

Technical personnel are available during normal business hours at CMA Headquarters should 
you, as an installer, have any questions please call 800-854-6417.
