CMA Dishmachines L-1X16 Manual De Usuario

Operation  

These cams were set at the factory but can be adjusted after final installation to maximize 
efficiency of chemical use (see section 4.1.1 Cam Adjustment.) 

 

The amount the machine is automatically filled each cycle is determined by the number 4 
cam.  When the number 4 cam switch actuator rides down into the cam groove, the 
solenoid valve on the fill line is energized causing the machine to fill.  Since the cam only 
controls the duration of the fill, varying water pressure can vary the amount the machine 
fills.  If the water pressure at the facility where the machine is installed is enough higher or 
lower than the water pressure was at the factory, the number 4 cam may need to be 
adjusted to correct the difference (see section 4.1.1 Cam Adjustment).  The machine 
should be filling to a level about 1” deep over the entire bottom of the wash tank, or just 
below the lower wash arm.  If the water pressure at the facility varies throughout the day, a 
pressure regulator may have to be installed on the water supply line to the machine to 
maintain constant pressure. 

Note:  If the optional sustainer heater is installed, the wash tank must be properly filled, 
and the machine properly leveled, or the float switch, which prevents the heater from 
turning on if the level is too low, will not permit the heater to turn on. 

 

The water pump takes in water from the drain sump and pumps it to the spray nozzles at a 
rate of 68 gallons per minute and a pressure at the nozzles of approximately 7 to 10 PSI.  
After being released through the spray arms and washing or rinsing the dishes, the water 
runs down the pan to the sump, through the drain screen, and back to the pump. 

The pump is driven by a 115 volt, 1 HP motor operating at 3450 RPM.  The impeller is 
mounted with a right-hand thread onto a 5/8” stainless steel shaft, which is coupled to the 
motor armature shaft.  See section Error! Reference source not found. Error! Reference 
source not found. for a detailed drawing. 

 

By listening to the normal pumping sound of the motor it can be determined if there is 
insufficient water in the machine, as you will hear a hesitation in the normal pumping 
rhythm, which is created by the air getting into the pump.  Cam 4 can be adjusted to 
increase the amount of water that is automatically fed into the machine during a cycle (see 
section 4.1.1 Cam Adjustment).
