Note: The required flowing water pressure to the dishwasher is 15-65 PSI. If pressures higher than 65 PSI are present, a pressure regulating valve must be installed in the water line to the dishwasher (by others). If flowing pressure is lower than 15 psi, improper machine operation may result.
1.2. L-1Xe Operational Cycle
The L-1Xe Operational Cycle has a total cycle time of 1½ minutes (90 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 90 seconds, 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 46-second wash cycle, then the drain pump drains the water out through the drain, turns off (allowing the machine to refill with clean rinse water) and then runs the pump for the 29-second rinse cycle.

3. Cam switch 2 controls the detergent pump and turns ON about 3 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

4. Cam switch 3 controls the drain function. At the end of the 46-second wash cycle, cam switch 3 energizes the drain pump allowing the drain pump motor to drain the wash water out of the machine. Cam switch 3 also increments the rack counter by one each cycle.

5. Cam switch 4 controls the water valve solenoid on the water supply to flush/fill the machine. At the end of the wash cycle the drain pump energizes (to pump the wash water out through the drain). With the drain pump stopped— the machine begins to fill for the rinse cycle. Once the machine has refilled sufficiently, the pump motor restarts continuing the rinse portion of the cycle as the filling of the wash tank completes.

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 wash tank heater. This cam assures that the wash tank 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

2.1. Introduction to the L-1Xe
The L-1Xe low temperature Dishwasher/Glasswasher is unique in its field; it has all the features of a standard commercial size machine packed into an under-counter, standalone dishwasher/glasswasher.
Operation of the L-1Xe is extremely easy. After initially filling the machine (see section 3.1.3 Filling the Machine), toggling the Fill/Start switch to the “START” position begins the Operational Cycle, which runs automatically.
The only external connections necessary are the power source, water supply and drain.
There are also accessories that can be chosen when desired such as the optional 4” and 6” legs.
See parts manual for the parts list and accessories available for the machine.
The supply water to the L-1Xe required is 120°F and recommended at 140°F. The pipe supplying the water must be ½”. The plumbing connection is located at the back of the machine. The machine comes with a drain hose. See section 2.2.2 Plumbing. This manual is structured to provide a complete reference guide to the L-1Xe. 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 dishwasher/glasswasher. 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. 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 if problems occur. CMA warranties the workmanship of the machine.
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.

2.2. 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. 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  to prevent door leaks.
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.
115 volt, 60 Hz dedicated circuit must be used to supply electrical power to the L-1Xe Dishmachine (see specification sheet page 1).

DO NOT USE POWER CORD OR GF OUTLET
This unit MUST BE hard-wired to a dedicated appropriately size circuit breaker.
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
  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 ball valve with a ½” female NPT connection located at the lower left-hand corner (facing the back) of the machine. A required 120°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.
  Machine is equipped with a ½” drain hose. 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.
  CMA recommends utilizing a water softening system to maintain water hardness measurements of 3.5 gpg (grains per gallon) or less. This will assure maximum results and optimum operation of the dishmachine.
  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.
  2.2.3. Installers Checklist

  • Dishwasher/Glasswasher checked for concealed damage
  • Hot water supply is required 120° F (49 C), recommended140° F (60 C)
  • Incoming water supply line is ½”

  • Service voltage and phase type are correct to machine data plate
  • Drain hose is installed with adequate air gap
  • Dishwasher/Glasswasher is properly grounded
  • Dishwasher/Glasswasher is properly leveled
  • Machine circuit breaker is labeled “DISHWASHER” or “GLASSWASHER”
  • Machine has been connected with correctly sized wire

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
The de-liming agents used to de-scale a commercial dishwasher, are highly caustic and de-liming must be done by a qualified chemical specialist.

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.

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 Temperature chemical-sanitizing dishwasher/glasswasher 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, toggle and hold the Fill/Start switch in the “FILL” position  until the water level in the wash tank reaches the water fill line.

3.2. General
Caution: Do not operate the dishwasher/glasswasher without the drain screen in place. Debris getting into the pump impeller can damage the pump.

1. Load a rack into the machine and close the door.
2. With the machine filled to the proper level, toggle Fill/Start switch to the “START” position – the machine will automatically begin its cycle. The red cycle light will illuminate while an operational cycle is in process.
3. At the end of the shift, drain the machine by holding the Drain push button switch, depressed position until the machine is completely drained. To avoid running the pump dry, do not hold the Drain push button switch 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 dishwasher/glasswasher interior for lime deposits.

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.

3.2.1. Pre-Scrapping
It is essential that the operator thoroughly understand the importance of pre- scrapping the wares before loading them. The L-1Xe 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 should permit the glasswasher/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

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 bottom 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, become noisy and reduce pressure to wash arms.
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 52 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 thread 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).
3.2.4. Deliming Dishmachine
Here are some recommendations for deliming dishmachine:

• If your dishmachine uses chemical sanitizers like chlorine, iodine, consult your chemical professional to verify chemicals used for deliming. Mixing chemicals can create a noxious gas or acid which could be harmful to humans or damage your machine.
• You have to manually drain the tank and fill with fresh water before adding the deliming agent.
• After filling the machine with fresh water, add the correct amount of deliming solution as recommended by the chemical manufacturer. Close the door.
• Toggle delime switch located behind lower front panel to “Delime” position and run the machine until the interior lime build up has been dissolved.
• After deliming, inspect the inside of the machine.
• If it is not delimed, run it again, following the deliming solution’s instructions.
• If the machine is, delimed, flip delime switch to “Normal” position, drain and refill the machine.
• Run for several minutes to remove residual deliming solution.
• Drain and refill the machine.

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.

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 (90 sec 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
All cams can be user adjusted except for cams 1, 3, and 8. The cam positions are all set at the factory and only the cams controlling the chemical pumps and water fill (cams 2, 4, 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 machine before gaining access to the timer assembly.
   Caution: One of the terminals on the main power switch remains “hot” even when the machine’s main power switch is turned off—so turn the power off at the circuit breaker.

2. Remove the (4) 10–32 x ½” screws securing front bottom panel.

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.
