With the machine powered up, toggling the START switch begins a cycle.

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.

After about 2 seconds, Cam 1—the Start 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.

Cam switch 7 controls the pump motor. The pump motor comes ON at the beginning
of the operational cycle and continues to run until the end of the drain function
(controlled by cam switch 3), at which time it turns off for about eight seconds
allowing time for the machine to refill enough to avoid running the pump dry before
the pump motor restarts and runs to the completion of the operational cycle.

The pump motor runs the pump for the 58-second wash cycle, then pumps the water
out through the drain, turns off (allowing the machine to refill with clean rinse water)
and then runs the pump for the 32-second rinse cycle.

Cam switch 3 controls the drain function. At the end of the 58-second wash cycle,
cam switch 3 energizes the drain valve solenoid allowing the pump motor to drain the
wash water out of the machine. Cam switch 3 also increments the rack counter by one
each cycle.

Cam switch 4 controls the water valve solenoid on the water supply to flush and fill
the machine. At the end of the wash cycle the drain valve is opened, the pump motor
continues to run (to pump the wash water out through the drain), and the Flush
function begins. At first, flushing the machine because the drain valve is still open,
then—with the drain valve closed and the pump motor stopped— the machine begins
to fill for the rinse cycle. Once the machine has refilled sufficiently, the pump motor
restarts carrying out the rinse portion of the cycle as the filling of the wash tank
completes.

Cam switch 2 controls the detergent pump and turns ON about 5 seconds after the
operational cycle is started and runs for a few seconds to provide sufficient detergent
for the wash cycle. This cam can be adjusted as necessary for proper detergent
dosage.
See section

4.1.1

Cam Adjustment

Cam switches 5 and 6 control the sanitizer and rinse pumps respectively. They turn
ON at the beginning of the rinse cycle and run for a few seconds to provide sufficient
sanitizer and rinse aid for the rinse cycle. These cams can be adjusted as necessary for
proper chemical dosage. See section

4.1.1

Cam Adjustment

Cam switch 8 operates the optional sustainer heater. This cam assures that the
sustainer heater only turns on when the dishmachine is

not

in a cycle. This prevents

the machine from drawing too much electrical current at any one time.

2. Getting Started

All sections of the manual address both the L-1C.Separate information on each glasswasher is only
provided where differences exist between the two models.

2.1.

Introduction to the L-1C

The L-1C Glasswashers are unique in their field; they have all the features of a standard commercial
size glasswasher packed into an under-counter, standalone glasswasher.

Operation of the L-1C is extremely easy. After initially filling the glasswasher (see section

3.1.3 Filling

the Machine

), toggling the Fill/Start switch to the “START” position begins the Operational Cycle, which

runs automatically.

To reduce service time, all electrical switches are mounted in a sliding drawer for easy access. The only
external connections necessary are the power source, water supply and drainpipe.

There are also accessories that can be chosen when desired such as the optional sustainer heater and
6” legs. The optional sustainer heater with thermostat is extremely practical for maintaining wash tank
temperature between cycles. The 800-watt heater will hold the wash tank temperature between 130°F
and 140°F while the glasswasher is not being run. See section

for the parts list and accessories

available for the glasswasher.

The supply water to the L-

1C must be a minimum of 140°F. The pipe supplying the water must be ½”

minimum. The plumbing connection is located at the back of the glasswasher. The drain is a 1" barbed
fitting located at the back of the glasswasher for easy attachment of your drain hose. See section

2.2.2

Plumbing

This manual is structured to provide a complete reference guide to the L-1C. It is presented in a manner
that all users will be able to comprehend and use as an effective tool in supporting the installation,
operation and maintenance of the glasswasher. The first section provides the specifications and details
of the operational cycle. The next section explains how the glasswasher is packaged and what to look
for when receiving the glasswasher. After unpacking the glasswasher, this manual explains how to
install and set up the glasswasher for use. Requirements are given for plumbing, wiring, and space
considerations.

These attributes of the glasswasher 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

operation to ensure that the glasswasher will be able to run optimally.

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 glasswasher. The function of the glasswasher itself is mostly
automatic and takes little training to put into full operation. The Operation section also includes
diagnostic considerations for the glasswasher if problems occur.

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 he

ating 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

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 glasswasher.

1. Start by removing the box and packaging material. Check for the following component parts:

A. Drain Screen:

The Wash Tank Scrap Screen is shipped inside the wash cavity of the glasswasher. This screen
must be in place during operation. It has been designed to perform two basic functions:



Strain water that is circulating through the spray arms and pump assembly.



A basket to catch heavy solids or broken glass that may plug the impeller.

B. Spray Arms

The end caps on the spray arms have been taped to protect them in shipping. Remove the tape
from the spray arm end caps.

C. Tube Stiffeners:

The tube stiffeners must be used to prevent the feed tubes from curling up inside the chemical
pail allowing the tip to rise out of the chemical. Remove the tie-wraps securing the tube
stiffeners to the glasswasher to free them up for use. Be careful not to remove any of the tie-
wraps securing the tube bundle.

2. Set the glasswasher in place and, using the leg adjusters, level from side-to-side and front-to-back.

Steam generated from normal operation may escape from door. Wood, laminates, veneers, etc. are
unsuitable materials for use in areas exposed to dishwasher steam and detergents. Stainless steel or
other moisture-resistant shields are recommended for surfaces adjacent to sides and tops of under
counter dishwashers.

2.2.1. Electrical

Prior to installation make sure the electrical supply is compatible with the specifications on the machines
data plate

A 15-amp, 115 volt, 60 Hz dedicated circuit must be used to supply electrical power to the L-1C
Glasswasher (see specification sheet page 1).

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.

Electrical and plumbing connections must be made by a qualified person who will comply with all available

Federal, State, and Local Health, Electrical, Plumbing and Safety codes

MODEL L-1C INSTALLATION & OPERATION MANUAL Rev. 1.00 A

Page

2.2.2. Plumbing



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.

The machine is equipped with a gate valve with a ½” female 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. The
water line used must be of sufficient length and flexibility to permit the machine to be moved for cleaning.
A 1” male NPT fitting is provided for the drain connection on the discharge port of the diverter valve
(lower, right-hand corner of machine). This fitting may be removed and user provided hardware might be
used if necessary to facilitate compliance with local plumbing codes. Code requires that the drain
discharge provide an air gap no less than 1” or two pipe diameters; whichever is greater, above the flood
level rim of an approved floor drain.

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.

3.1.2. Chemicals



Assure there is a sufficient supply of chemicals before beginning a shift.

Note:

Use only commercial-grade detergents and rinse aids recommended by your chemical

professional. Do not use detergents and rinse aids formulated for residential dishwashers.

Low Temperatures chemical-sanitizing dishmachines must not exceed 6% sodium hypochlorite
solution (bleach) as the sanitizing agent. Higher levels may damage stainless or components.
Follow the directions precisely that are on the litmus paper vial and test the water on the surface
of the bottom of the glasses. Concentration should be 50 p.p.m. minimum to 100 p.p.m.
maximum. If concentration is incorrect contact your chemical supplier.

3.1.3. Filling the Machine



With the power ON, press and hold the Fill/Start switch

in the “FILL” position until

the water level in the wash tank is about 1” deep, for best results use water level
indicator located at the back of the wash tank.

3.2.

General

Caution:

Do not operate the dishmachine without the drain screen in place. Debris getting into

the pump impeller can damage the pump.

1. Load a rack of glass into the machine and close the door.

With the machine filled to the proper level, press rocker Fill/Start switch to the “START”
position

– the machine will automatically begin its cycle. The green running light on the

switch will illuminate while an operational cycle is in process.

At the end of the shift, drain the machine by holding the Drain rocker switch in the “DRAIN”
position until the machine is completely drained. To avoid running the pump dry, do not hold
the Drain rocker switch in the “DRAIN” position any longer than necessary.

4. Remove and clean the drain screen. Remove and clean the spray arms. (See wall chart

instructions).

5. Replace the drain screen and spray arms.

6. Inspect your dishmachine interior for lime deposits. If de-liming is required, a de-liming

agent should be used for best results in accordance with chemical supplier’s instructions.





Toggle De-

lime switch to the “De-lime” position.



Allow the machine to run for several minutes or until the interior lime build up has
been dissolved.



The chemicals and water level must be programmed by a qualified chemical specialist.

The de-liming agents are highly caustic and de-liming must be done by qualified chemical specialist.

MODEL L-1C INSTALLATION & OPERATION MANUAL Rev. 1.00 A

Page



Flip De-

lime switch to the “Normal” position.

Warning: Close the dishmachine door before activating the De-lime Switch.

Skin contact

with de-liming solutions can cause severe irritation and possible burn. Always wear
protective clothing and goggles when handling chemicals. Contact your chemical supplier
for specific safety procedures for the use of de-liming solution.

3.2.1. Pre-Scrapping

It is essential that the operator thoroughly understand the importance of pre-scrapping the
glasses before loading them. The L1C is equipped with a removable drain screen. The drain
screen can be easily removed for cleaning between Operational Cycles of the dishmachine.
Properly pre-scrapping the glasses should permit the glasswasher to operate for an entire shift
before needing to remove and clean the drain screen.

3.2.2. Proper Chemical Dosage

The amount of chemical delivered, whether it is detergent, sanitizer or rinse aid, is determined
by its respective cam on the cam timer.



Cam number 2 runs the detergent pump



Cam number 5 runs the sanitizer pump



Cam number 6 runs the rinse aid pump

These cams were set at the factory but must be adjusted after final installation to maximize
efficiency of chemical use (see section

4.1.1 Cam Adjustment

3.2.1. Proper Filling

The #4 cam must be adjusted properly to automatically dispense the correct amount of water
each cycle. When the #4 cam switch actuator rides down into the cam groove, the water
solenoid valve will activate to fill the machine. This cam only controls the duration the water
valve is activated dispensing water inside the wash tank

(see section

4.1.1 Cam

Adjustment

).The #4 cam is properly adjusted when the water level in the wash tank is at the

“Fill Line” located on the back wall of the wash tank. If water pressure fluctuates, install a
Pressure Regulator Valve (PRV) to maintain proper water levels between cycles. If water level is
too low wash pump will cavitate and become noisy and lose pressure to wash arms.

Note:

The tank must be properly filled, and the machine properly leveled, or the float switch,

which prevents the heater from turning on if the level is too low, will not permit the heater to turn
on.

3.2.2. Water Pump

The water pump takes in water from the drain sump and pumps it to the spray nozzles at a rate
of 35 gallons per minute and a pressure at the nozzles of approximately 7 to 10 PSI. After being
released through the spray arms and washing or rinsing the dishes, the water runs down the pan
to the sump, through drain screen, and back to the pump.

A 115-volt, 1 HP motor operating at 3450 RPM, drives the pump. The impeller is mounted with a
right-hand t

hread onto a 5/8” stainless steel shaft, which is coupled to the motor armature shaft.

3.2.3. Pump Cavitation

By listening to the normal pumping sound of the motor it can be determined if there is insufficient
water in the machine, as you will hear a hesitation in the normal pumping rhythm, which is
created by the air getting into the pump. Cam 4 can be adjusted to increase the amount of water
that is automatically fed into the machine during a cycle (see section

4.1.1 Cam Adjustment

MODEL L-1C INSTALLATION & OPERATION MANUAL Rev. 1.00 A

Page

4. Maintenance

The maintenance procedures detailed in this section are to be performed by qualified personnel.

4.1.

Timer assembly

The standard timer assembly consists of a ½ RPM (2 minutes per revolution) motor turning a common
shaft, which, in turn, rotates eight cams. As the cams rotate, they control various functions and the
sequence of the operational cycle.

The individual function of each of the 8 cams is identified by a label on the timer assembly. Cams 1
through 8 are positioned from left to right beginning with the “START” cam (cam 1).

START

Timer Assembly Label

The “HEATER” label is not present if the optional sustainer heater is not installed on the machine.

Except for cams 1, and 3, all other cams can be user adjusted. The cam positions are all set at the
factory and only the cams controlling the chemical pumps (cams 2, 5 & 6) should ever need adjusting.
Each micro switch on the timer assembly is turned on and off by the cam its actuator rides on. For all of
the cams, except cams 1, 7 and 8, its corresponding switch is ON when its actuator is down in the cam
groove.  (Cams 1, 7 and 8 are reverse acting and are turned ON when the micro switch actuator is up
out of the groove.)  Opening the groove of any cam other than cams 1, 7 or 8 will increase the amount of
time that the micro switch is held ON. The cams are slip-fit and a cam adjustment wrench is provided (a
small screw driver or the edge of a table knife can also work to adjust the cams).

4.1.1. Cam Adjustment

The two sides of each cam connect to the shaft with a slip-fit so all cam adjustments are made
by rotating one side of the cam on the shaft to either increase or decrease the size of the cam
groove.

1. Turn off the circuit breaker providing power to the glasswasher before pulling the control

drawer out to access the timer assembly.

Caution:

One of the terminals on the main power switch remains “hot” even when the

glasswasher’s main power switch is turned off—so turn the power off at the circuit breaker.

2. Remove the two 8

–32 x ½” Screws securing the control drawer and slide it out to its fully

extended position.

3. Using the timer assembly label, determine which cam is to be adjusted. Double check by

counting over from cam 1 to the cam to be adjusted.

4. Determine which edge of the cam groove to be adjusted is the leading edge (contacts the

limit switch actuator first when the shaft is rotating) and which edge of the groove is the
trailing edge. The leading edge of the cam groove determines when in the cycle the control
action begins and should not be changed.

5. Adjust the trailing edge of the cam groove by rotating the appropriate side of the cam in the

proper direction to either increase or decrease the cam’s groove; resulting in increasing or
decreasing the total time that switch will be held ON.
