2. Getting Started

2.1. Introduct i on 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.

Operation of the CMA-180 is automatic. When the door is opened and then closed, the wash cycle begins automatically. To initially fill the machine daily, open the hand operated fill valve (optional auto fill available) on the top of the machine. The machine is full when water begins to flow into the scrap trap. The wash tank heater will maintain the wash water temperature at 155°F. The booster heater will produce a minimum of 180°F final rinse water each cycle providing the incoming water supply is a minimum 140°F.

This manual is structured to provide a complete reference guide to the CMA-180. It is presented in a manner that all users will be able to comprehend and use as an effective tool in supporting the operation and maintenance of the dishmachine. The first section explains how the machine is packaged and what to look for when receiving the machine.

Instructions are provided in the manual explaining how to unpack the machine and then install and set up the machine for use. Requirements are given for plumbing, wiring, and space considerations. These attributes of the machine are always taken into consideration by our we ll- trained sales representatives prior to the order being placed. In the manual, additional installation guidance is given to ensure the machine can run at optimum conditions.

The

Operation Section of the manual may be used for instruction and procedures when required.

We make this portion of the manual easy to understand so that all levels of operators may be able to read and comprehend the operation of the machine. The function of the machine itself is mostly automatic and takes little training to put into full operation. The Operation Section also includes diagnostic considerations for the machine when problems occur.

Our mission is to provide our customers with the highest quality products and the highest quality service, always delivering more than we promise and more than he or she expects. We will strive to do business the way the customer wants to do business, on a mutually profitable basis.

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. Electrical

The control panel provides a 1” conduit connection point on the rear of the panel. Refer to Section 3 for wiring options.

This machine is equipped to handle both single and three phase applications. See Section 1: Specifications 1.1 for the proper electrical ratings.

2.2.2. Plumbing

Minimum 140°F / Minimum 180°F (if machine ordered without booster heater, water supply ¾” – minimum 20 psi, 6 gpm flow rate and 60 gph recovery rate. Plumbing connection located on the top of the machine.

The drain is a two inch (2”) pipe sleeve attached by “No-Hub” plumbing connection at the bottom of the scrap trap. Account’s drain should be no higher than 11” to allow the machine to drain properly.

2.2.3. Nova Detergent and Rinse Dispenser

The NOVA Detergent and Rinse Dispenser has its own reference manual. Familiarize yourself with the dispenser’s reference manual before proceeding with installation.

1. The NOVA dispenser is pre-wired with a multi-conductor electrical cable that is to be run through a conduit to the power block inside the control panel drawer. Use a ½” watertight conduit meeting all local and national codes. A conduit fitting is present on the bottom of the dispenser where the power cable exits. Use the same conduit fitting in the back of the control box. The probe is also pre-wired (see two violet wires routed from the control box to the probe location inside the wash tank heater thermostat enclosure).

i. Run an appropriate length of ½” conduit from your dispenser to the control

box where it will be secured. The conduit needs to be of sufficient length and flexibility to permit the machine to be moved for cleaning without having to disconnect any wiring.

Electrical and pluming connections must be made by qualified person who comply with all

available Federal, State, and Local Health, Electrical, Plumbing and Safety codes

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.
