1. With the machine powered up toggling the START switch begins a cycle.
a) Toggling the START switch energizes both the Cam Timer motor and the Instant Start
Relay. The Instant Start Relay latches ON the power to the Cam Timer motor so that
the START switch can be released a moment after it has been toggled without the Cam
Timer motor losing power.
b) After about 1.5 seconds the Cam Timer’s first cam—the Cam Timer Motor Cam—
latches ON the power to the Cam Timer motor and drops out the Instant Start Relay.
The Cam Timer motor continues to run for a total of 2 minutes, at which time it
switches OFF—resetting the Cam Timer—and waits for the next START command.
2. The Cam Timer’s third cam controls the Wash Pump. The Wash Pump comes ON about 3
seconds into the Operational Cycle and continues to run for 94 seconds. This 94-second
period is the Wash Cycle.
3. At the same time that the Wash Pump comes ON the Cam Timer’s fourth cam powers ON
the Optional Drain Pump—if one is present—and keeps it running for about 7 seconds
before powering OFF. This cam turns ON again midway through the Rinse Cycle and
stays ON for 10 seconds, turning OFF 2 seconds after the Rinse Cycle has completed.
4. About 3 seconds after the Wash Cycle has completed the Cam Timer’s second cam, which
controls the Rinse Cycle, turns ON—energizing the Water Solenoid—and stays ON for 16
seconds. This 16-second period is the Rinse Cycle.

2. Getting Started
2.1. Introduction to CMA-180UC
The CMA-180UC is a hot water sanitizing, single rack, under-coun ter dishmachine. It is a
standalone machine featuring a self-contained booster heater. The only external connections
necessary are power supply, water supply, drainpipe, and optional chemical dispensers. The
machine uses re-circulated wash water and fresh water final-rinse.
Operation of the CMA-180UC is extremely user friendly. To initially fill the machine each day,
push the switch marked “FILL”. The machine is full when water begins to flow into the scrap tray.
The booster 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.
The supply water to the CMA-180UC must be a minimum of 140°F at 24 PSI (Pounds per Square
Inch) with a 6 GPM (Gallons Per Minute) flow rate and 60 GPH (Gallons Per Hour) recovery rate.
The pipe supplying the water must be ½” minimum. The plumbing connection is located at the
back of the machine. (See specification sheet on page
The drain is a 1" barbed fitting on the back of the machine for easy attachment of your drain
hose.
The machine retains the features of the standard CMA-180 Series in that it has a scrap tray and
the manner in which the tank is filled ensures that the dishes are always rinsed with fresh water
instead of re-circulated water. The CMA-180UC is the first under-counter dishmachine of its kind
to discharge soil from the wash tank into a scrap tray outside of the wash chamber. This feature
keeps the wash water much cleaner over long periods of time. The scrap tray may be emptied on
a periodic basis without interruption of the flow of work, thereby providing a much cleaner
environment for the wash and rinse cycle. There are also enhancements that can be chosen
when required such as drain pump kits and other accessories. Refer to Section
for the parts list and accessories available for the machine.
This manual is structured to provide a complete reference guide to the CMA-180UC. 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.
After unpacking the machine, this manual explains how to 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 well-trained sales representatives prior to the
order being placed. In the manual, guidance is also given for installation to ensure that the
machine will be able to 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
includes diagnostic considerations for the machine when problems occur.
The next section of the manual is the
diagram for the machine. CMA warranties the workmanship of the machine.
We are committed to providing the best machines and customer service in the food industry and
your feedback is welcome.

Getting Started
2.2. Receiving and Installation
The dishwasher is shipped from the factory in a corrugated box on a wooden pallet. The
installation guidelines give a systematic procedure for setting up the machine.
Start by removing the packaging material. Unwrap the machine and check for the following
component parts:
The Wash Tank Scrap Screen is shipped inside the wash cavity of the machine. This screen must
be in place during operation. It has been designed to perform two basic functions:
1. Strain water that is circulating through the spray arms and pump assembly.
2. A basket to catch broken glass, or heavy solids that may plug the impeller.
Set the machine in place, and level from side-to-side and front-to-back.
2.2.1. Electrical
A 50-amp, single-phase 230 volt, 60 Hz dedicated circuit should be used to supply electrical
energy to the CMA-180UC dishwasher (see specification sheet page
three power wires, which include a current carrying neutral. An additional fourth wire must be
provided for ground. CMA and local codes require the CMA-180UC to be hardwired using #8
AWG (90°C) copper wire (minimum). Approximately 4-feet of ¾” flexible conduit with power leads
(L-1, L-2, Neutral and Ground) extending out of the conduit are provided for easily connecting the
power at installation. The power connection must be located such that there is sufficient length of
the flexible conduit remaining to permit the machine to be moved for cleaning.
2.2.2. Plumbing
The machine is equipped with a ½” NPT connection located at the lower left-hand corner (facing
the back) of the machine. A 140°F water line should be plumbed to this point (see specification
sheet page
2). The water line used must be of sufficient length and flexibility to permit the
machine to be moved for cleaning.
The supply water to the CMA-180UC must be a minimum of 140°F at 24 PSI (Pounds per Square
Inch) with a 6 GPM (Gallons Per Minute) flow rate and 60 GPH (Gallons Per Hour) recovery rate.
The pipe supplying the water must be ½” minimum. The plumbing connection is located at the
back of the machine. (See specification sheet on page
The CMA-180UC may be supplied with an optional drain pump for elevated drains. For floor
gravity drain applications the drain pump should not be used and a good commercial grade hose
needs to be connected to the discharge side of the diverter valve (drain valve) and run to the floor
drain. If removing a drain pump, safe-end (insulate electrically) the white and purple wires and
secure them out of the way. If a drain pump is used with a floor drain, the drain hose must rise 12
to 16” before dropping to the floor drain (to reduce any chance of the pump cavitating).
2.2.3. Detergent And Rinse Dispenser
Note: If you are installing the optional CMA Supplied Detergent and Rinse
Dispenser follow the instructions in Section
