1. With the glasswasher powered up, toggling the START switch begins a cycle.
a) 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.

b) 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.
2. 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 glasswasher 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 57-second wash cycle, then pumps the water
out through the drain, turns off for about 8 seconds (allowing the glasswasher to refill
with clean rinse water) and then runs the pump for the 48-second rinse cycle.
3. Cam switch 3 controls the drain function. At the end of the 57-second wash cycle,
cam switch 3 energizes the drain valve solenoid allowing the pump motor to drain the
wash water out of the glasswasher. Cam switch 3 energizes the drain valve solenoid
again at the end of rinse cycle.
4. Cam switch 4 controls the water valve solenoid on the water supply to flush and fill
the glasswasher. 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 glasswasher because the drain valve is still open,
then—with the drain valve closed and the pump motor stopped— the glasswasher
begins to fill for the rinse cycle. Once the glasswasher has refilled sufficiently, the
pump motor restarts carrying out the rinse portion of the cycle as the filling of the
wash tank completes.
5. 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
6. 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
7. Cam switch 8 controls the water valve solenoid on the water supply to initial fill the
glasswasher.

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 Glasswasher), 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 5 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.
The Maintenance section of the manual is for qualified personnel and provides trouble shooting
procedures and specific maintenance instructions.
The final section of the manual is the Parts Manual. This section has the parts lists and wiring
diagram for the glasswasher.
CMA warranties the workmanship of the glasswasher.
At CMA we are committed to providing the best glasswashers and customer service in the food
and beverage industry and your feedback is welcome.

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.
2.2.1. Electrical*
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). The power connection must be such that there is
sufficient length of flexible conduit or power cord to permit the glasswasher to be moved for
cleaning.
2.2.2. Plumbing*
The glasswasher is equipped with ½” female NPT connection located at the lower left-hand corner
(facing the back) of the glasswasher. 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 glasswasher 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 glasswasher). This fitting may be removed and user provided
hardware may be used if necessary to facilitate compliance with local plumbing codes. Code
requires that the drain discharge provides an air gap no less than 1” or two pipe diameters,
whichever is greater, above the flood level rim of an approved floor drain.
2.2.3. Post Instructions
Mount the wall chart provided in a conspicuous place and instruct the operators on proper cleaning
and operation of the L-1C. The instruction chart is also provided as an appendix to this manual
(see appendix).
*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

3. Operation
3.1. Initial Setup
3.1.1. Check…
Drain screen is in place
Spay arms and end plugs are secure
3.1.2. Chemicals
•Assure there is a sufficient supply of chemicals before beginning a shift.
3.1.3. Filling the Glasswasher
•With the power ON, the glasswasher will be automatically filled until the water
level in the wash tank is about 1” deep.
3.2. General
Caution: Do not operate the glasswasher without the drain screen in place. Debris
getting into the pump impeller can damage the pump.
1. Load a rack of properly pre-scrapped dished into the glasswasher and close the door.
2. With the glasswasher filled to the proper level, toggle the Fill/Start rocker switch to
the “START” position – the glasswasher will automatically begin its cycle. The green
running light will illuminate while an operational cycle is in process.
3. At the end of the shift, drain the glasswasher by holding the Drain toggle switch in the
“DRAIN” position until the glasswasher 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 or instructions provided in Appendix A: Operator & Cleaning
Instructions).
5. Replace the drain screen and spray arms.
6. Inspect your glasswasher 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 glasswasher to run for several minutes or until the interior lime build
up has been dissolved.
•Flip De-lime switch to the “Normal” position.
Warning: Close the glasswasher 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
dishes before loading them. The L-1C is equipped with a removable drain screen. The
drain screen can be easily removed for cleaning between Operational Cycles of the
glasswasher. Properly pre-scrapping the dishes 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 can be adjusted after final installation to maximize
efficiency of chemical use (see section 4.1.1 Cam Adjustment.)
3.2.3. Proper Filling
The amount the glasswasher is automatically filled each cycle is determined by the
number 4 cam. When the number 4 cam switch actuator rides down into the cam groove,
the solenoid valve on the fill line is energized causing the glasswasher to fill. Since the
cam only controls the duration of the fill, varying water pressure can vary the amount the
glasswasher fills. If the water pressure at the facility where the glasswasher is installed is
enough higher or lower than the water pressure was at the factory, the number 4 cam may
need to be adjusted to correct the difference (see section 4.1.1 Cam Adjustment). The
glasswasher should be filling to a level about 1” deep over the entire bottom of the wash
tank, or just below the lower wash arm. If the water pressure at the facility varies
throughout the day, a pressure regulator may have to be installed on the water supply line
to the glasswasher to maintain constant pressure.
Note: If the optional sustainer heater is installed, the wash tank must be properly filled,
and the glasswasher 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.
3.2.4. Water Pump
The water pump takes in water from the drain sump and pumps it to the spray nozzles at a
rate of 68 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 the drain screen, and back to the pump.
The pump is driven by a 115 volt, 1 HP motor operating at 3450 RPM. The impeller is
mounted with a right-hand thread onto a 5/8” stainless steel shaft, which is coupled to the
motor armature shaft.
3.2.5. Pump Cavitation
By listening to the normal pumping sound of the motor it can be determined if there is
insufficient water in the glasswasher, 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 glasswasher during a cycle
(see section 4.1.1 Cam Adjustment).

Operation
MODEL L-1C INSTALLATION & OPERATION MANUAL Rev. 1.00 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).
Timer Assembly Label
Cams 2, 4,5,6,8 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 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.
