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.
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 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.
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 welltrained 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.
We are committed to providing the best machines and customer service in the food industry and
your feedback is welcome.
CMA warranties the workmanship of the machine.

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
*
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
MODEL CMA-180 INSTALLATION & OPERATION Rev. 2.03
Page 5
flexibility to permit the machine to be moved for cleaning without having to
disconnect any wiring.
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.

female connectors provided, and connected to the pre-wired violet wires in
the control box.

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. Insert the probe into the hole from inside the wash tank and
secure it with the probe retaining nut provided. Connect ring connectors to the
probe with nuts and star washers provided.
5. The final step of installing the CMA supplied Detergent and Rinse Dispenser is
programming it to your specific application. The reference manual supplied with
the dispenser shows you how to program it.
Keep in mind while reading the reference manual that the CMA-180 operates
in “probe” mode. (This mode is selected by setting a value of “1” in screen
21).
Screen 22 must be set to “1” (Door).
There are four user functions with this dispenser. Their operation is described in the
reference manual.

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).
SINGLE PHASE POWER
NOTE: 80 amp service is required when CMA-180 is wired for single-phase with the booster
heater. See “Electrical Requirements” section for DUAL 1-phase power supply. Circuit breaker

NOTE: CMA recommend that this Model CMA-180 initial parts kit be
kept on hand, as a back up supply, in the event your machine should
require emergency service. All the parts included in this kit are
unique to the CMA-180 dishmachine, and are essential to the “quality”
operation and customer service to the CMA-180 unit.
