Note: The required flowing water pressure to the dishwasher is 15-65 PSIG. If pressures higher
than 65 PSIG are present, a pressure regulating valve must be installed in the water line to the
dishwasher (by others). If flowing pressure is lower than 15 psi, improper machine operation may
result.

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. To initially fill the machine daily, press “Auto Fill” rocker
switch. Auto Fill timer will fill the machine until water begins to flow into the scrap trap. When the
door is opened and then closed, the wash cycle begins automatically. 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 machine canbe used as a Low Temp machine provided NSF Standard 29 Chemical
Sanitizing Feeder (not supplied with machine) is installed.
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 well-
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.
We are committed to providing the best machines and customer service in the food
industry and your feedback is welcome.
DISCLAIMERS
CMA expressly disclaims any and all warranties, express or implied, relating to the installation of any and all CMA equipment that is installed by chemical dealers, contracted servicers or third
party servicers to CMA equipment. If the installation instructions are not followed exactly (to the letter), or, if any person or company conducting the installation of the CMA equipment, revise the
installation procedures or alter the instructions in any manner, the CMA warranty becomes void. If, due to the improper installation of CMA equipment, this equipment ceases to operate properly or
affects other parts of the CMA dishwashing equipment, in that the other parts become defective, the CMA warranty becomes void. CMA will not be liable or responsible or warrant CMA
equipment, due to improper installation of any CMA model dishwasher.
CMA does NOT endorse “Tankless On-Demand” water heaters for use on CMA Dishmachine products.On most applications, the
volume of hot water required for commercial dishmachines exceeds the capacity of these types of heating sources. You will find
that most, if not all, commercial dishmachines have been programmed with auto-filling features that require quick filling, with a
designated limited time.
CMA DOES endorse, and highly recommends, the standard “tank” style water heaters, sized properly to handle each particular
facility with their water heating requirements. A “tank” style water heater stores and supplies a large capacity of preheated water
before providing hot water to the dishmachine. To meet required health codes, there must be a reliable and consistent flow of
adequate hot water supplied to the dishmachine. If the facilities’ “tank” style water heater is marginal in size, CMA recommends
installing a proper size Hatco Booster Heater, a CMA’s E-Temp 40 or 70-degree-rise Booster Heater (that can be installed on CMA
Conveyors), or a CMA Temp-Sure Booster Heater (for door and undercounter dishmachines). All are designed to adequately
achieve results.

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
*
Prior to installation make sure the electrical supply is compatible with the specifications
on the machines data plate.
WARNING: Electrical and grounding connections must comply with the applicable
portions of the National Electrical Code and/or other local electrical codes.
Note: For supply connections, use copper wire only rated at 90 degree C minimum.
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.
