1.2. L-1X and L-1X16 Operational Cycle
The L-1X and L-1X16 Operational Cycle has a total cycle time of 2 minutes (120
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 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 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 57-second wash cycle, then pumps the water
out through the drain, turns off for about 8 seconds (allowing the machine 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 th e
wash water out of the machine. Cam switch 3 also increments the rack counter by one
each cycle.
4. 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.
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 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.

Getting Started
2. Getting Started
All sections of the manual address both the L-1X and the L-1X16. Separate information on each
machine is only provided where differences exist between the two models.
2.1. Introduction to the L-1X and L-1X16
The L-1X and L-1X16 Dishmachines are unique in their field; they have all the features of a
standard commercial size machine packed into an under-counter, standalone dishmachine.
Operation of the L-1X and L-1X16 are extremely easy. After initially filling the machine (see
section
Operational Cycle, which runs automatically.
To reduce service time, all electrical components are mounted in a sliding drawer for easy access.
This “Works-In-A-Drawer” can be removed by unplugging a single connector for easy
serviceability.
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 sustaine r 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 machine is not being run. See section Error! Reference
source not found. Error! Reference source not found. for the parts list and accessories available
for the machine.
The supply water to the L-1X and L-1X16 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 machine. The
drain is a 1" barbed fitting located at the back of the machine for easy attachment of your drain
hose. See section
This manual is structured to provide a complete reference guide to the L-1X and L-1X16. 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 dishmachine. The first section
provides the specifications and details of the operational cycle. The next section explains how the
machine is packaged and what to look for when receiving the machine. After unpacking the
machine, this manual explains how to install and set up the machine for use. Requirements are
given for plumbing, wiring, and space considerations. These attributes of the machine are al ways
taken into consideration by our well-trained sales representatives prior to the order bei ng placed.
In the manual, guidance is also given for operation to ensure that the machine will be able to run
optimally.
The
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
diagnostic considerations for the machine 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 machine.
CMA warranties the workmanship of the machine.
At CMA we are committed to providing the best machines and customer service in the food and
beverage industry and your feedback is welcome.
