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. Seconds: 0 10 120 20 30 40 50 60 70 80 90 100 110 Instant Start Relay Cam 1 Start/Stop Cam 2 Detergent Cam 3 Cam 4 RINSE WASH F L U S H Drain FILL Flush/Fill Cam 5 Sanitizer Cam 6 Rinse Pump Motor Cam 7 Heater Cam 8 1.
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.
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.
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.
Getting Started 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.
Operation 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 Machine • 3.2. 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.
Operation 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.
Maintenance 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.
