Getting Started 2. Getting Started 2.1. Introduction to CMA-66 The CMA-66 is designed to give maximum cleaning in 66 inches. It represents the cleaning power of machines twice its length. The curtains incorporated in the machine minimize transfer from tank to tank during the wash and sanitizing procedures. Energy costs for running the CMA-66 have been greatly reduced by the introduction of stage washing.
Getting Started 2.2. Receiving and Installation When you receive your new CMA-66, complete the assembly by installing the scrap tray assembly with its overflow chute, the two wrapper shields and the curtain rods, which are shipped inside the machine. After the box has been removed from the machine, remove the left and right stainless steel wrapper shields and bolt them in place with the nuts and bolts provided. The wrapper shield with the extra curtain clamps mounts onto the dirty end of the machine.
Getting Started 2.3. Receiving and Installation (Old Models) When you receive your new CMA-66, complete the assembly by installing the scrap tray assembly with its overflow chute, the two wrapper shields and the curtain rods, which are shipped inside the machine. After the box has been removed from the machine, remove the left and right stainless steel wrapper shields and bolt them in place with the nuts and bolts provided.
Getting Started 2.3.1. Electrical * A 3-phase 208-240 volt AC, 60 Hz dedicated circuit should be used to supply electrical energy to the CMA-66 dishwasher (see specification sheet page 2). Connect the wire that has the highest voltage (stinger lead) to the main contactor’s power terminal L2. Power lead wires (L1, L2 and L3) used for the CMA-66 at installation must comply with all local and State electrical codes. 2.3.2.

On a 3-phase machine the water pump motors are also 3-phase and, depending on which terminal each phase is connected to, the motor can rotate in either direction. Check the direction of rotation by removing the dust cap on the back of the motor. The motors must turn clockwise looking at the shaft from the back of each motor.
Getting Started 2.3.4. Scrap Tray Assembly and Overflow Chute Installation The scrap tray assembly and overflow chute, which came packaged inside the machine, can easily be installed by executing the following steps: Figure 2.3.4 below illustrates the assembly as it would appear for a Left-to-Right machine – a Right-toLeft machine would simply be the mirror image.
Getting Started 2.3.5. Pump Impeller Note Figure 2.2.5 Installation: When installing the water pump impeller the Nylon Lock Nut indicated by the arrow in Figure 2.2.5 must be in place to prevent the impeller from spinning off of the shaft and damaging the motor. Removal: The Nylon Lock Nut indicated by the arrow in Figure 2.2.5 must be removed before attempting to remove the water pump impeller. MODEL CMA-66 Installation & Operation Manual Rev. 1.

Getting Started 2.3.8. Field Installed Accessories Installation of the accessory chemical pumps must be performed by qualified personnel. 2.3.8.1. Chemical Dispensers 1. Checkvalves should be installed directly at the mixing chamber coupling. There are two 1/8” FPT mounting holes provided, which will position the checkvalves parallel to the machine avoiding any chemicals from dripping onto the stainless steel should a leak develop.
Getting Started 2.4. Safety Tips for the CMA-66 DANGER: Always turn off the circuit breaker at the wall when working on this dishmachine. Even with the machine’s power switch off there is a live connection coming to the switch, so turn off the circuit breaker as well. CAUTION: Do not get in the path of the conveyor rocker arm or the conveyor’s moving bar. Do not reach into the rocker arm area without first making sure the dishmachine is turned off at the circuit breaker.
Operation 3. Operation 3.1. Initial Setup 3.1.1. Auto Fill Timer/ Auto Re- Fill Timer Both timers for the CMA-44 are set at the factory, but may need to be adjusted at the time of installation depending on supply water pressure. When the power switch is activated, the machine should fill until water begins to overflow into the scrap tray, at which point it should be set to stop filling.
Operation Note: If at any time less than a full Auto Fill cycle is desired with the IDEC brand timer, the Auto-Fill can be interrupted (stopped) by turning off the power to the machine. The machine will resume normal operation upon restoring power without continuing the Auto Fill cycle. 3.1.3. Rinse Pressure Regulator The CMA-66 requires a supply water pressure of 24 PSI minimum. The pressure is then reduced by the supply water regulator.
Operation 3.2. Beginning Operation To run the dishmachine, perform the following steps: 1. Close both drains (valve handles in vertical position). CLOSE CLOSE 2. Turn on the power to the dishmachine. 3. Open the fill-valve and fill the machine until it overflows out of the pre-wash tank into the scrap tray or, if the Auto Fill option is present, press the AUTO FILL switch to fill the machine with water. 4. Turn the heater on. The temperature of the water in the tank should be 140°F – 150°F.
Operation 6. At the end of the shift and after heavy periods of accumulation, clean the three strainer trays inside the machine. STRAINER TRAY Also, at the end of each shift, remove and clean the six spray arms. Then reinstall them into the machine. SPRAY ARM Also, when water becomes heavily soiled, drain the tanks and refill the machine. 7. Check chemical buckets. Make sure there is an adequate supply of detergent, rinse aid and (CMA-66L only) sanitizer.
Operation The sanitizing pump operates when the fresh water enters the machine during final rinse. The water is treated at 50 PPM (parts per million). The pressure regulator is adjusted to 20-PSI. This allows 0.8 (CMA-66L), or 0.94 (CMA-66H) gallons of water to enter the machine each time a rack is washed. It is recommended that the 5-1/2% chemical solution be standardized to allow uniform dispensing of the sanitizing solution into the flow of rinse water as the machine operates.
Operation 6. Replace all the strainer trays into their proper position and fill the machine. 7. Place a rack into the machine and observe the spray pattern of the pre-wash, the wash, and the final rinse. a. Check the titration of the wash tank at this point. b. While the rack is in the final rinse, check for 50 PPM residual chlorine in the final rinse. c. Observe the final rinse vacuum breaker for leaks. 8. Run a stemware or glass rack through the machine and check the results on the glassware. a.
