2. Getting Started
2.1. Introduction to CMA-180VL
The CMA-180VL is a hot water sanitizing, single rack, door-type dishmachine. It is a stand-alone
machine featuring a self-contained booster heater. The only external connections necessary are
power supply, water supplies, drainpipe, and chemical dispensers. The machine utilizes re-
circulated wash water and fresh water final rinse.
The machine is equipped with the built in Heat Recovery System which reduces significantly the
humidity in the dishwashing room. The Heat Recovery System uses the heat of the steam
generated during the wash cycles to warm up the in-feed water (41F -65F) before entering the
booster heater.
This manual is structured to provide a complete reference guide to the CMA-180VL. 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.
CMA warranties the workmanship of the machine.
Caution: the CMA-180 VL has a Heat Recovery (HR) system comprised of heat exchange coils that can become
restricted or clogged if the water supplied to the machine contains lime scale, also known as hard water
condition. The cold water supplied to the CMA-180 VL should be analyzed and treated to maintain maximum 3.5
grains per gallon (gpg) or 60 parts per million (ppm) water hardness to prevent scale build up conditions and to
optimize dishmachine operation. The first sign of scale build up conditions will be restricted water flow or
having no flow of water to the rinse arms.
CMA recommends utilizing a water softening system to maintain water hardness measurements of 3.5 gpg or
less. This will assure maximum results and optimum operation of the dishmachine.
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.

2.1.1. Plumbing Chart
The buildings ambient or cold tap water (41F-65F) is supplied to the dishwasher through the cold
water inlet valve located at the bottom of the dishwasher. The ambient/cold water enters the
condenser at the top of dishwasher, as the water travels down through the condenser. The steam
and heat rising through from the wash cabinet is used to preheated the incoming water to 130 to
140 degrees to feed the dishwashers own booster heater. The booster heater located underneath
the wash tank boosts the final-rinse water temperature to 180 to 190 degrees for a proper
sanitizing final-rinse. At the end of the 60 second wash-cycle, a 30 second steam evacuation
cycle will immediately begin. Once the steam evacuation cycle has been completed, the
operation indication light will turn off indicating the cycle has been completed and the rack of
dishes can be removed and a new wash-cycle can be started.
The hot water source is used to fill the dishwasher with hot water needed to fill the wash tank,
and to flush or clean down the condenser. The flush-down or cleaning of the condenser is only
done at the end of day and sometimes after each service when the main power switch is turned
to the off position.

2.2.2. Plumbing
*
Minimum 140°F hot water supply 1/2”. Minimum 41°F cold water supply ½”– minimum 20
psi, 6 gpm flow rate. Plumbing connections located on the bottom of the machine.
Notice to Plumber: The plumber connecting this machine is responsible for making
certain that the water lines are THOROUGHLY FLUSHED OUT BEFORE connecting to
the dishwasher.
Ask your municipal water supplier for details about your local water conditions prior to
installation. Recommended water hardness is 3 grains per gallon or less.
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 dishwasher or booster heater reveals lime buildup after the
equipment has been in service, water treatment is recommended. If water softener is
already in place, ensure there is a sufficient level of salt.
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.

8. A 7/8” detergent fitting hole is provided in the wash tank behind the machine.
9. Check the machine operating temperatures. Adjust if necessary.
a. After the machine has warmed up for five to ten minutes (5 – 10 min.), observe
the wash and rinse temperatures. The wash temperature must be 155°F
minimum. The rinse temperature must be 180°F minimum. If necessary, adjust
the temperatures by removing the panel in front of the respective heater and
turning the adjustment stem clockwise to increase.
NOTE: Rinse water temperature must be observed during the rinse cycle.
10. Check all water and drain fittings for leaks.
11. Install the wall chart and instruct the machine operator on the proper cleaning and
operation of the CMA-180VL.
The flush-down or cleaning of the condenser is done when the main power switch is turned to the
off position.
Caution: Booster Heater
Booster heater is shipped on the dishmachine empty to prevent freezing. When the
machine is powered up for the first time, the booster heater must be filled immediately to
prevent damage to the heating element. See Section 2.2.7 (4c.)
To prevent booster heater element damage, CMA has removed a wire from the high limit
switch. When initially filling of a newly installed dishmachine, you must fill the booster
tank prior to connecting the removed wire. When water is observed entering the wash tank
this indicates the booster tank is full and removed wire can be connected. Failure to follow
these important instructions will destroy the heating element because of dry -firing.
Warning:
The Door Safety Interlock (DSI) is used to prevent the wash cabinet doors from being
opened while the dishwasher is in operation. The interlock prevention arm is extended
when the wash cycle begins, and remains extended during the duration of the full 61-
second wash/rinse cycle including the 41-Second steam evacuation cycle. Once the full
cycle is finished, the door safety interlock arm will be retracted thus allowing the doors to
wash cabinet to be opened.
