INSTALLATION INSTRUCTIONS I N S T R U C T I O N S VISUAL INSPECTION: Before installing the unit, check the container and machine for damage. A damaged container is an indicator that there may be some damage to the machine. If there is damage to both the container and machine, do not throw away the container. The dishmachine has been inspected and packed at the factory and is expected to arrive to you in new, undamaged condition.
CHEMICAL DISPENSING EQUIPMENT This page does not apply to the JPX-140 dishmachine. This unit is not supplied with chemical pumps. The JPX-160 and JPX-200 dishmachines are supplied with detergent and rinse additive chemical feeder pumps. I N TO PREPARE PUMPS FOR OPERATION S Locate the open ends of the chemical tubes, insert the end of each tube onto the hub on the brass weight, and place each one in the T R appropriate container. U A. Red Tubing = Detergent C T B.
CHEMICAL TIMER ADJUSTMENTS This page does not apply to the JPX-140 dishmachine. I N S T R U C T I O N S In general, it should not be necessary to alter the machine settings. The factory settings have been established to give the best results. IMPORTANT: To avoid wasting chemicals, remove tubes from soap and rinse-agent bottles before using the Service Mode. The system will always give an initial dose during the first cycle after switch-on, even though the wash tank may still be full.
CHEMICAL TIMER ADJUSTMENTS CONTINUED Use the chart below to determine the initial time values for INITIAL RINSE, CYCLE RINSE, INITIAL SOAP, and CYCLE SOAP based on the desired concentration of the chemical being used. Check the concentration of the chemicals after running a few cycles and readjust as necessary. I JPX-160 Chemical Ratio Chemical (parts water to Concentration one part chemical) (percent in water) 5000 3000 2500 2000 1500 1000 800 600 400 300 250 200 0.02% 0.03% 0.04% 0.05% 0.07% 0.10% 0.
OPERATION INSTRUCTIONS I N S T R U C T I O N S PREPARATION: Before proceeding with the start-up of the unit, verify the following: that could be harmful to human beings. In order to do this, ware must be properly prepared prior to being placed in the machine. 1. Remove all solid wastes in order to avoid obstructing strainers, drain and wash jets. DAILY MACHINE PREPARATION: Refer to the section entitled “PREPARATION” at the top of this page and follow the instructions there.
OPERATION INSTRUCTIONS (CONTINUED) JPX-140 Wash/Rinse Arm Assembly SHUTDOWN AND CLEANING: Remove the central knob (A) to remove the wash arms. Check the nozzles to ensure they are not clogged with debris. If they are, simply unscrew the nozzle retainer for the affected nozzle and remove it to clean out the debris. Flush the arms out with fresh water. IMPORTANT: Remove only one nozzle at a time to ensure that you replace all of the nozzles as required.
PC BOARD Display Contrast Adjuster. Turn clockwise to adjust the brightness of the display. It will not unscrew. When it reaches the brightest spot, it will restart at the dimmest setting. Red lights will illuminate when the corresponding output signal is “on”.
TROUBLESHOOTING SECTION WARNING: Inspection, testing and repair of electrical equipment should be performed only by qualified service personnel. Certain procedures in this section require electrical tests or measurements while power is applied to the machine. Exercise extreme caution at all times. If test points are not easily accessible, disconnect power, attach test equipment and reapply power to test. When replacing electrical parts, disconnect power at source circuit breaker.
