SECTION 2: INSTALLATION/OPERATION INSTRUCTIONS 12
SECTION 2: INSTALLATION/OPERATION INSTRUCTIONS INSTALLING THE JFT DISHMACHINE NOTE: All JFT models are accompanied by a certified Jackson technician for the initial installation. Many of the questions and problems that arise, as well as the proper procedures for installation, should be directed to this person. 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.
SECTION 2: INSTALLATION/OPERATION INSTRUCTIONS INSTALLING THE JFT DISHMACHINE (CONTINUED) CONNECTING THE DRAIN LINE: The drains for the models covered in this manual are gravity discharge drains. All piping from the 2” connection on the load section must be pitched (1/4” per foot) to the floor or sink drain. All piping from the machine to the drain must be a minimum 3” N.P.T. and shall not be reduced. There must also be an air gap between the machine drain line and the floor sink or drain.
SECTION 2: INSTALLATION/OPERATION INSTRUCTIONS INSTALLING THE JFT DISHMACHINE (CONTINUED) STEAM TRAP CONNECTIONS: There are steam traps provided on the discharge side of all steam heating devices. A typical unit will have traps on the following: wash section heating coil outlet, power rinse section heating coil outlet, rinse booster heater outlet, and an optional blower dryer section heating coil outlet. All steam traps can be seen by removing all of the above mentioned sections lower dress panels.
SECTION 2: INSTALLATION/OPERATION INSTRUCTIONS INSTALLING THE JFT DISHMACHINE (CONTINUED) gram to see the order in which the provided washers, wheels, locknuts, and plate connectors are arranged for proper operation. Continue this process of pulling sections through and connecting sections until the belt is completely installed.
SECTION 2: INSTALLATION/OPERATION INSTRUCTIONS DELIMING OPERATIONS DELIMING OPERATIONS: In order to maintain the dishmachine at its optimum performance level, it will be required to remove lime and corrosion deposits on a frequent basis. A deliming solution should be available from your detergent supplier. Read and follow all instructions on the label of the deliming solution.
SECTION 2: INSTALLATION/OPERATION INSTRUCTIONS DETERGENT CONTROL Detergent usage and water hardness are two factors that contribute greatly to how efficiently your dishmachine will operate. Using detergent in the proper amount can become, in time, a source of substantial savings. A qualified water treatment specialist can tell you what is needed for maximum efficiency from your detergent, but you should still know some basics so you’ll understand what they are talking about.
SECTION 2: INSTALLATION/OPERATION INSTRUCTIONS OPERATING INSTRUCTIONS Before the first start up of the machine, check that all tools, cleaning rags, and all foreign parts are removed from the operation areas of the machine. PREPARATION: Before proceeding with the start-up of the unit, verify the following: 1. Ensure wash arms, rinse arms, pump suction strainers, pan strainers, and curtains are all installed correctly. 2. Close all doors on dishmachine. 3. Close the drain valve(s). 4.
SECTION 2: INSTALLATION/OPERATION INSTRUCTIONS OPERATING INSTRUCTIONS (CONTINUED) DAILY MACHINE PREPARATION: Refer to the section entitled “PREPARATION” at the top of this page and follow the instructions there. Afterwards, check that all of the chemical levels are correct and/or that there is plenty of detergent available for the expected workload. WASHING WARE: To wash, simply place ware on the track at the load end of the machine.
SECTION 3: PREVENTATIVE MAINTENANCE 21
SECTION 3: PREVENTATIVE MAINTENANCE PRE-SCRAPPING/STRAINERS Preventative maintenance should only be performed by authorized service personnel. If you have questions about who is authorized then please contact Jackson Technical Service. Maintenance performed by unauthorized personnel can void a warranty. Note: No maintenance should be performed during normal operation of the machine.
SECTION 3: PREVENTATIVE MAINTENANCE DAILY/WEEKLY/MONTHLY MAINTENANCE Daily: 1. Drain and clean the dishmachine as per the cleaning instructions supplied with this manual. During cleaning, any items that may appear to be broken or failed should be reported to authorized service personnel. Weekly: 1. Delime the machine. NOTE: The deliming agent that you may use may require more or less frequency in application.
SECTION 3: PREVENTATIVE MAINTENANCE MONTHLY (CONTINUED)/QUARTERLY/ANNUAL MAINTENANCE found. Correct any deficiencies before returning the unit to an operating status. 5. Verify that the conveyor operates in both high and low speed. Start the machine as normal, ensuring that all personnel are clear. Put the machine in low speed using the Speed Selector Switch located on the front panel. Allow the unit to operate normally for five minutes ensuring that the speed appears to remain constant.
SECTION 3: PREVENTATIVE MAINTENANCE ITEMS NOT REQUIRING MAINTENANCE Items that should not require maintenance: 1. Thermostats - the thermostats for your JFT machine are factory set so that your machine will operate in accordance with accepted regulatory parameters. Upon initial installation, your Jackson representative may adjust the the thermostats if required but otherwise they should never need to be corrected again.
SECTION 4: TROUBLESHOOTING SECTION 26
SECTION 4: TROUBLESHOOTING SECTION COMMON PROBLEMS 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.

SECTION 5: SERVICE PROCEDURES 29
SECTION 5: SERVICE PROCEDURES VACUUM BREAKER REPAIR PARTS KIT These dishmachines are equipped with vacuum breakers to serve as back-flow prevention devices. ASSE requirements specify what type of back-flow prevention is necessary on dishmachines. Vacuum breakers, unlike air gaps, have certain parts that have specific tolerances and design aspects that must be met in order to function properly.
SECTION 5: SERVICE PROCEDURES VACUUM BREAKER REPAIR PARTS KIT (CONTINUED) 7. If any of these conditions are present, replace the old plunger with the new one from your kit. Verify that the new plunger is also free from defects. If it is not, contact your Ecolab representative immediately. 8. The plunger should drop into the vacuum breaker and seat. Ensure it is not flipped upside down (the orange seal ring should be up towards the top of the vacuum breaker). 9. Pick up the cap and examine it.
