SECTION 2: INSTALLATION/OPERATION INSTRUCTIONS INSTALLATION INSTRUCTIONS VISUAL INSPECTION: Before installing the unit, check the container and machine for damage. A damaged container is an indi- cator 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.
SECTION 2: INSTALLATION/OPERATION INSTRUCTIONS ELECTRICAL INSTALLATION INSTRUCTIONS ELECTRICAL POWER CONNECTION: Electrical and grounding connections must comply with the applicable portions of the National Electrical Code ANSI/NFPA 70 (latest edition) and/or other electrical codes. Disconnect electrical power supply and place a tag at the disconnect switch to indicate that you are working on the circuit. The dishmachine data plate is located on the right side and to the front of the machine.
SECTION 2: INSTALLATION/OPERATION INSCTRUCTIONS CHEMICAL DISPENSING EQUIPMENT TO PREPARE PUMPS FOR OPERATION The PA-1/PA-2 dishmachines are supplied with detergent, rinse additive and sanitizer dispensing chemical feeder pumps. Locate the open ends of the chemical tubes with the tube stiffeners and place each one in the appropriate container. A.
SECTION 2: INSTALLATION/OPERATION INSCTRUCTIONS OPERATING INSTRUCTIONS PREPARATION: Before proceeding with start-up verify the following: A. Sump strainer is in place. B. Drain stopper is installed. C. Check that the wash arms are securely screwed into the stationary bases and rotate freely. Also check that the end plugs are securely screwed into the ends of all wash arms.

SECTION 2: INSTALLATION/OPERATION INSCTRUCTIONS OPERATING INSTRUCTIONS (CONTINUED) PREPARING DISHES: Preparation of the ware will help ensure good results and less re-washes. If not done properly the dish- es will not be clean and will reduce the efficiency of the dishmachine. The following steps should be followed to ensure good results: A.
SECTION 2: INSTALLATION/OPERATION INSCTRUCTIONS CAM TIMER OPERATION (PA-1/PA-2) The PA-1/PA-2 cam timer is a 1 minute, 30 second, 8-cam timer that controls the operation of the dishmachine. The following is a description of the set points for each cam and the function of each switch. CAM 1: Cam 1 is a cut cam with a single notch and serves as the cycle/reset control.
Page 21
SECTION 2: INSTALLATION/OPERATION INSCTRUCTIONS CAM TIMER OPERATION (PA-1/PA-2) (CONTINUED) CAM 6: Cam 6 is an adjustable can and controls the detergent pump. FUNCTION: The detergent pump cam works off the normally closed contacts of cam 6. This requires the switch arm to be held open by the cam and allowed to drop into the notch to operate the pump.
SECTION 2: INSTALLATION/OPERATION INSCTRUCTIONS TIMING SEQUENCE (PA-1/PA-2 MODELS) 2 SECONDS INTO CYCLE *Wash pump starts, runs for 40 seconds, then shuts down. Controlled by C2 cam. 4 SECONDS INTO CYCLE *Detergent feed pump is energized. The length of time will be field determined. Time will depend on the detergent used and water conditions.
SECTION 3: PREVENTATIVE MAINTENANCE PREVENTATIVE MAINTENANCE The dishmachines covered in this manual are designed to operate with a minimum of interaction with the operator. However, this does not mean that some items will not wear out in time. There are many things that operators can do to prevent catastrophic damage to the dishmachine. One of the major causes of component failure has to do with prescrapping procedures.
SECTION 4: TROUBLESHOOTING SECTION COMMON PROBLEMS WARNING: inspection, testing and repair of electrical equipment should be performed only by qualified service per- sonnel. 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 re-apply power to test.
Page 28
SECTION 4: TROUBLESHOOTING SECTION COMMON PROBLEMS Problem: Dishmachine cycles continuously. 1. “Cycle reset” switch is loose. Reposition the switch assembly, bend the metal lever if necessary. 2. Faulty “cycle reset” switch. Measure between the BLACK/YELLOW and ORANGE wires on the “cycle reset” switch while the timer is rotating.
Page 29
SECTION 4: TROUBLESHOOTING SECTION COMMON PROBLEMS Problem: The wash motor does not run even when the wash relay is manually depressed; other functions work. 1. Loose wire connections to motor, delime switch, or from contactors. Tighten wires as necessary. 2. Mechanical binding in pump. If the motor has the correct incoming voltage, and its overload is tripping, repair or replace the pump.
Page 30
SECTION 4: TROUBLESHOOTING SECTION COMMON PROBLEMS Problem: Sanitizer pump runs continuously. 1. Shorted prime switch. If there is not 120 volts between the GREY and WHITE/RED wires to the prime switch, replace it. 2. Shorted sanitizer microswitch on the cam timer. If there is not 120 volts between the ORANGE and GREY wires on the san- itizer microswitch when the switch is out of the “home”...
SECTION 5: SERVICE PROCEDURES RINSE SOLENOID VALVE REPAIR PARTS KIT STEPS These dishmachines are equipped with electrical solenoid valves to allow for automatic fill and rinse. These valves are designed to specific tolerances and design aspects 1. Remove the top screw with the 5/16” nutdriver. Remove the that must be met in order to function properly.
