1. With the ma chine powered up, toggl in g the START switch begins a cycle.
a) Toggling the START sw itch en ergizes both the Cam Timer motor a nd the Instant Staii
Relay. Th e Instant S ta1i Relay latches ON the power to the Cam Tim er motor so that
the START sw itch can be released a moment after it has been toggled without the C am
Timermotor losing power.
b) After about 1. 5 seco nd s the C am Timer 's first cam- the C am TimerMotor Cam-
latches ON the power to the Ca m Tim er motor and drops out the Instant Staii Relay.
Th e C am Timer motor continues to nm for a total of 3 mi nu tes, at which time it
sw itches OFF- resetting the Cam Time r- and waits for the next START command.
2. Th e C am Timer 's third cam controls the Wash Pump. Th e Wash Pump comes ON about 3
seco nd s into the Operational Cy cle and conti nu es to nm fo r 96 seco nd s. 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 “Safe-
T-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.

2. Getting Started
2.1 . Introduction to CMA-181VL
The CMA- 181 VL is a hotwatersanitizing, single rack, under-counter glasswashe r. It is a stand-
alone machine featuring a self-contained booster heater. The only external connections
necessary are po w er supply, cold water supply, drain pipe, and chemical dispensers. The glass
washer uses re-circulated wash waterand a fresh water final-rinse.
The unit is equipped with a built in Heat Recovery System whi ch 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 cycl es to warm up the incoming cold water
(41 F -65F) before entering the booster heater.
Operation of the CMA-181VL is extremely userfriendly. To initially fill the machine each day,
push the Power switch to the "ON" position. The glass washer wi ll be automatically filled to the
correct level.
The boostertank heater wi ll maintain the wash water temperature at appr ox imate ly1 55° F. The
booster heater wi ll produce a minimum of 180°F final rinse water each cycle.
The co ld water supply to the CMA-181VL must be be tw een 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 (Gallons per
Hour) recovery rate. The pipe supplying the water must be½ " minimum. The plumbing
connection is located at the low er right rear of the glass washer (if facing the front). (See
specification sheet on page 2 ).
This manual is structured to provi de a complete reference gui de 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 operati on and ma intenance of the glass washer. The first section explains ho w
the unit is packaged and what to lookfor when receiving the glass washer.
After unpacking the glass washer, this manual explai ns how to install and set up for proper
operation. Requirements are given for plumbing, wiring, and space considerations. Guidance is
given for insta ll ation to ensure that the glass washer wi ll be ab le to operate at optimum level s.
The Operation Section of the manual may be used for instruction and procedur es when required.
We make this porti on of the manual easy to understand so that all levels of operators may be
ab le to read and comprehend the operation of the machine. The function of the glasswasher
itself is mostly automatic and takes little training to put into fu ll operati on . The Operati on Section
also includes diagnostic considerations for the machine when probl ems occur.
We are committed to pr ov iding the best machines and customer service in the food industry and
your feedback is welcome.

CMA does NOT endorse "Tankless On-Demand" water heaters for use on CMA Dishmachine products. On mostapplications, the
volume of hot water required for commercial dishmachines exceeds the capacity of these types of heating sources. You will find
that most, if n ot all, commercial dishmachines have been programmed wi th auto-filling features that requi re quick filling, with a
designated li mited ti me .
CMA .Q,Q,5§. endorse, and highly recommends, the standard "ta nk" style water heaters, sized properly to handle each pa rt icular
facil ity w it h their water heating requirements. A "ta n k" 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 supp li ed to the dishmachi ne . If the facilities' "tank" style water heater is margi na l 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). Al l are designed to adequately
achieve results.

The building's co ld tap water (41F-65F) co nn ec ts to the stainless steel braided hose at the rear of
the glass w as h er .The co ld / ambient wat er travels from there through the condenserto the unit's
booster heater. Atthe end of operating cycle, hot/humidi fi ed air inside the wash chamber is
circulated past the condenser coils, raising the temperature of the incoming water fl owing through
those coils to approximately 130F to 140F degrees before entering the booster heater. The
booster heater, locat ed below th e wash chamber, wi ll raise the fi nal-rinse wat er temperature to
approximately 180F to 190F degrees ensuring a proper sanitizing final-rinse. The glasswash er
has a SAFE-T-TEMP feature which wi ll extend the wash cycle if the final rinse temperature in the
booster heater has not reached a minimum 180F. After an operating cycle is finished, which is

2.2. Receiving and Installation
The glass washer is shipped from the factory in a corrugated box on a wooden pallet. The
installation guidelines give a systematic procedure for setting up the glass washer.
Start by removing the packaging material. Unwrap the unit and check for the following
component parts:
The Wash Tank Scrap Screen is shipped inside the wash cavity. This screen MUST t be in place
during operation to strain the water circulating through the pump assembly and spray arms,
catching the broken glass or debris that could otherwise clog the pump impeller and plug the
spray arms.
Set the unit in place, and level from side-to-side and front-to-back to prevent door leaks.
Some water vapor generated from normal operation may escape from the door jambs. Wood,
laminates, veneers, etc. are unsuitable materials for use in areas exposed to this escaping water
vapor and detergents. Stainless steel or other moisture-resistant shields are recommended for
surfaces adjacent to sides and tops of under counter glass washers.
2.2.1. Electrical1
Prior to installation make sure the electrical supply is compatible with the specifications on the
glass washer data plate.
A single-phase 230 volt, 60 Hz dedicated circuit should be used to supply electrical energy to the
CMA-181VL glass washer (see specification sheet page 2). This system requires three power
wires, which include a current carrying neutral. An additional fourth wire must be provided for
ground. 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 unit to be moved for cleaning.
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.
2.2.2. Plumbing2
Notice to Plumber: The plumber connecting this unit is responsible for making certain that the
water lines are THOROUGHLY FLUSHED OUT BEFORE connecting to the glass washer.
The unit is equipped with a 48” braided hose with ½” NPT connection located at the lower left-
hand corner (facing the back) of the unit. A cold 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 unit to be moved for cleaning.
The pipe supplying the water must be ½” minimum. The plumbing connection is located at the
back of the glass washer. (See specification sheet on page 2). Note: high iron levels in the water
supply can cause staining and may require an iron filter. High chlorine levels in the water supply
can cause pitting and may require a chloride removal system. If an inspection of the wash tank or
booster heater tank reveals lime buildup after the glass washer has been in service, water
treatment is recommended. If a water softener is already in place, ensure there is a sufficient
level of salt.
1,2All electrical and plumbing connections must be made by a qualified person and comply with all
available Federal, State, and Local Health, Electrical, Plumbing and Safety codes listed in Sec.17.1 of
UL921.

Warning:
CMA recommends utilizing a water softening system to maintain water hardness
measurements of 3.5 gpg (grains per gallon) or less. This will assure maximum results
and optimum operation of the dishmachine.
2.2.3. Detergent And Rinse Chemical Dispenser (Optional).1•
Optional bu ilt-in chemical dispenser Assembly (CMA P/N 14585.00) has easy access for
chemical settings behind the front kick pane
l. Bo th initial charge and recharge is factory pre-set.
Basic settings for both detergent and rinse speed are 50%. Operating fine-adjustment screws on
the dispenser can control the amount
of chemicals drawn into chemical lines.
■
I II
.
e
■
5 0o/o -
Undercounter machine wi th the optional dispenser must be ordered separately, as option at time
of order. Optional dispenser has to be pre-wired pri
or to shipment (see electrical diagram for
wiring options).
Note: Use only commercial-grade detergents and rinse aids recommended
by yourchemical
professiona
l. Do not use detergents and rinse ai ds formulated for resi de ntial dishwashers.
2.2.4. Safe -T-Temp Feature
The CMA "Safe-T-Temp" feature assures the fi nal rinse cycle is always at a consistent minimum
of 180 degrees.
How it works: the "Safe -T-temp" function operates offthe 5th cam (labeled "Safe -T-Temp") on
the timer assembl
y. When the cam timerassembly completes th e wash cycle, and approach es
the final rinse portion of the cycl e, the "Safe -T-Temp" micro switch wi ll drop into the cam sl ot and
pause the cam timer assembly
if the booster heater has not reached 180 degrees. The glass
washer wi
ll remain in wash cycle mode until 180 degree rinse temperature is met, and at this time
the cam timerw
il l advance automatica ll y into the rinse cycle and dispense 180 degrees rinse
water over the glasses.
