2. Getting Started 2.1. Introduction to CMA-180 The CMA-180 is a hot water sanitizing, single rack, door-type dishmachine. It is a stand-alone machine featuring a self-contained booster heater (optional). The only external connections necessary are power supply, water supply, drainpipe, and chemical dispensers. The machine utilizes recirculated wash water and fresh water final rinse. The CMA-180 can be converted both as a straight through and corner with a door handle kit.
2.2. Receiving and Installation Step 1: Remove packaging material. Step 2: Remove service manual and machine legs from inside the wash tank. Step 3: Install legs into dishmachine leg lockets and adjust the feet. Set the machine in place. Level the machine side – to – side and front – to – back. Step 4: It is recommended that a distance of at least eight inches (8”) be between the table scrap sink and the dishmachine. 2.2.1.
ii. Run your dispenser wires through the conduit to the control box. iii. Run your probe wires to the control box. iv. With the machine’s power “OFF”, connect your detergent and rinse dispenser wires to the red and blue terminals of the power block supplied inside the control box. The table that follows lists the function of each conductor of the multiconductor electrical cable.
2. Remove the plug from the mixing chamber located by the vacuum breaker on the back of machine; and install the rinse injection fitting (supplied with your dispenser). 3. A 7/8” detergent injection hole is provided in the back of the wash tank. Remove the S.S. plug and install the detergent fitting (supplied with your dispenser). 4. A 7/8” chemical probe hole is provided in the front of the wash tank heater just below hi limit switch.

2.2.6. Installation Checklist Dishmachine checked for concealed damage. Hot water supply is 140° (60°C) Incoming water supply line is ¾”. Incoming water supply is 6 gpm minimum capable at 20 psi flow pressure. Machine circuit breaker is properly sized. Service voltage and phase type are correct to machine data plate. High leg of voltage is connected to L2 (three-phase). Dishmachine is properly ventilated. Floor drain plumbing is installed with air gap. MUST MEET LOCAL CODES.
NOTE: Rinse water temperature must be observed during the rinse cycle. 10. Check all water and drain fittings for leaks. 11. Install the wall chart and instruct the machine operator on the proper cleaning and operation of the CMA-180. NOTE: Booster Heater Booster heater is shipped on the dishmachine empty to prevent freezing. When the machine is powered up for the first time, the booster heater must be filled immediately to prevent damage to the heating element. See Section 2.2.6 (4d.
2.2.8. Electrical Requirements The CMA-180 comes standard factory, wired for 3-phase operation. Check the electrical data plate to confirm this. If the account requires 1 phase, refer to “Electrical Requirements”, Section 1-A, for proper wiring instruction for conversion. Also check the wiring diagram to properly wire the terminal power block, tank heater, and booster heater for 1 phase (or 1B diagram below).
