Note: The required flowing water pressure to the dishwasher is 30-65 PSIG. If pressures are higher
than 65 PSIG, a pressure regulating valve must be installed in the water line to the dishmachine (by a
qualified person). If flow pressure is lower than 30 PSIG, improper operation may result.

1.2. CMA-181VL Operational Cycle
The CMA-181VL Operational Cycle (including water vapor evacuation) has a total cycle time
of three (3) minutes (180 seconds). The Timing Diagram and the steps listed below detail the
individual functions that are executed during each Operational Cycle.

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 th e 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 3 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 96 seconds. This 96-second
period is the Wash Cycle.

3. The Cam Timer’s fourth cam powers ON the Drain Pump midway through the Rinse
Cycle and stays ON for 10 seconds, turning OFF 2 seconds after the Rinse Cycle has
completed. 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 14 seconds. This 14-second period is the Rinse Cycle.
4. After the Rinse Cycle is completed Cam Timer’s sixth cam turns Fan for 60 seconds steam
evacuation.
5. The Cam Timer’s seventh cam controls the fill. The fill comes on 2 seconds after the fan
starts. Water fills into the booster until the fill pressure switch senses that the booster is
full and closes the water fill solenoid. The water fill solenoid will close before cam timer
times out.
6. When the Cam Timer assembly approaches the final rinse portion of the cycle, the “SafeT-Temp” fifth micro switch will pause the cam timer assembly if the booster heater has
not reached 180 degrees. The Dishmachine will remain in wash cycle mode until a
minimum 180-degree rinse temperature is reached, at which time the Cam Timer will
advance automatically into the rinse cycle and dispense 180 degree rinse water over the
glasses.

Getting Started
2. Getting Started
2.1. Introduction to CMA-181VL
The CMA-181VL is a hot water sanitizing, single rack, under-counter glass washer. It is a standalone machine featuring a self-contained booster heater. The only external connections
necessary are power supply, cold water supply, drain pipe, and chemical dispensers. The glass
washer uses re-circulated wash water and a fresh water final-rinse.
The unit is equipped with a built in Heat Recovery System which significantly reduces the water
vapor created during the wash and rinse cycles. The Heat Recovery System uses the heat from
the water vapor generated during the wash and rinse cycles to warm up the incoming cold water
(41F -65F) before entering the booster heater.
Operation of the CMA-181VL is extremely user friendly. To initially fill the machine each day,
push the Power switch to the "ON" position. The glass washer will be automatically filled to the
correct level.
The booster tank heater will maintain the wash water temperature at approximately155°F. The
booster heater will produce a minimum of 180°F final rinse water each cycle.
The cold water supply to the CMA-181VL must be between 41°F - 65°F at a minimum 30 PSI.
(Pounds per Square Inch) with a 6 GPM (Gallons per Minute) flow rate and 60 GPH (Gallon s per
Hour) recovery rate. The pipe supplying the water must be ½” minimum. The plumbing
connection is located at the lower right rear of the glass washer (if facing the front). (See
specification sheet on page 2).
This manual is structured to provide a complete reference guide to the CMA-181VL. 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 glass washer. The first section explains how
the unit is packaged and what to look for when receiving the glass washer.
After unpacking the glass washer, this manual explains how to install and set up for proper
operation. Requirements are given for plumbing, wiring, and space considerations. Guidance is
given for installation to ensure that the glass washer will be able to operate at optimum levels.
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 glass washer
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
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 heal th 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.

2.1.1. Plumbing Chart
The building’s cold tap water (41F-65F) connects to the stainless steel braided hose at the rear of
the glass washer. The cold / ambient water travels from there through the condenser to the unit's
booster heater. At the end of operating cycle, hot/humidified air inside the wash chamber is
circulated past the condenser coils, raising the temperature of the incoming water flowing through
those coils to approximately 130F to 140F degrees before entering the booster heater. The
booster heater, located below the wash chamber, will raise the final-rinse water temperature to
approximately 180F to 190F degrees ensuring a proper sanitizing final-rinse. The glass wash er
has a SAFE-T-TEMP feature which will extend the
booster heater has not reached a minimum 180F. After an operating cycle is finished, which is
indicated by the “CYCLE” light turning off, the fan circulating the air inside the wash chamber will
continue to run an extra 65 seconds. This allows additional condensation removal. Opening the
door anytime after the operating cycle is finished and before the fan has timed out, will stop the
fan and allow the start of a new cycle.
