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
MODEL L-1X & L-1X16 INSTALLATION & OPERATION MANUAL Rev. 1.14 Page

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.

Getting Started
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 machine.
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 machine. 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 dishmachine to free them up for use. Be careful not to remove
any of the tie-wraps securing the tube bundle.
2. Set the machine in place and, using the leg adjusters, level from side-to-side and front-to-
back.
2.2.1. Electrical*
A 20-amp, 115 volt, 60 Hz dedicated circuit must be used to supply electrical power to the L-1X or
L-1X16 Dishmachine (see specification sheet page
there is sufficient length of flexible conduit or power cord to permit the machine to be moved for
cleaning.
1). The power connection must be such that
2.2.2. Plumbing*
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 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-1X and L-1X16. 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

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 Machine
• With the power ON, toggle and hold the Fill/Start switch in the “FILL” position
until the water level in the wash tank is about 1” deep, or just below the
bottom wash arm.
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 properly pre-scrapped dished into the machine and close the door.
2. With the machine filled to the proper level, toggle the Fill/Start switch to the “START”
position – the machine 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 machine by holding the Drain toggle switch in the
“DRAIN” position until the machine is completely drained. To avoid running the pump
dry, do not hold the Drain toggle 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.
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-1X and L-1X16 are 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 dishes should permit the dishmachine 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
Operation

Operation
These cams were set at the factory but can be adjusted after final installation to maximize
efficiency of chemical use (see section
3.2.3. Proper Filling
The amount the machine 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 machine to fill. Since the cam only
controls the duration of the fill, varying water pressure can vary the amount the machine
fills. If the water pressure at the facility where the machine 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
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 machine to
maintain constant pressure.
Note: If the optional sustainer heater is installed, the wash 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.
3.2.4. 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. See section Error! Reference source not found. Error! Reference
source not found. for a detailed drawing.
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 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).

Maintenance
4. Maintenance
The maintenance procedures detailed in this section are to be performed by qualified person nel.
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).
RINSESANI.FLUSHDRAINDET.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).
MOTOR
PAUSE
HEATER
*
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 machine before pulling the control drawer
out to access the timer assembly.
Caution: One of the terminals on the main power switch remain s “hot” even when the
machine’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.
