  • Page 4: Installation Instructions

    INSTALLATION INSTRUCTIONS Jackson MSC Inc. provides technical support for all of the dishmachines detailed in this manual. We strongly recommend that you refer to this manual before making a call to our technical support staff. Please have this manual with you when you call so that our staff can refer you, if necessary, to the proper page.
  • Page 5 INSTALLATION INSTRUCTIONS (Cont.) WATER SUPPLY CONNECTION: Ensure that you have read the section entitled “PLUMBING THE DISHMACHINE” above before pro- ceeding. Install the water supply line (3/4” pipe size minimum) to the end of the Y-strainer. It is recommended that a water shut-off valve be installed in the water line between the main supply and the machine to allow access for service.

  • Page 6: Operation Instructions

    OPERATION INSTRUCTIONS PREPARATION: WARE PREPARATION: Proper preparation of ware will help ensure good results and less re-washes. If not done properly, 1. Ensure that the pump intake strainer (1) and basket overflow ware may not come out clean and the efficiency of the dishma- strainer (2) are inserted and tight.

  • Page 7: Preventative Maintenance

    PREVENTATIVE MAINTENANCE Proper maintenance of you Jackson dishmachine will insure optimum service with a minimum of down time. 1. To delime the booster tank. a. Remove the support pipe nut and lift the whole hood assembly away from the unit. b.

  • Page 8: Rinse Head/Wash Head Assemblies

    RINSE HEAD / WASH HEAD ASSEMBLIES 1. Turn master switch to off position. 2. Open hood and drain machine by lifting overflow strainer. 3. When empty, replace overflow strainer. 4. Remove the pin holding the rinse feed pipe and remove the feed pipe and rinse head assembly. 5.

  • Page 9: Timer For 10 Dishmachines

    TIMER FOR 10 DISHMACHINES General Description: The timer is a self-contained (frame mounted) timer of the repeating cycle type. It is mounted on the control panel of the control box, to control the automatic functions of the machine. It consists of a clock motor which operates on 60 cycle AC, 220 VAC.

  • Page 10: Function Of Switches, Circuit Breaker & Indicating Lights

    FUNCTION OF SWITCHES, CIRCUIT BREAKER & INDICATING LIGHTS Circuit Breaker: Rated 15 amps, controls power to the control circuit only, I.E. timer, relays, solenoid valve, water level control and motors. The circuit breaker does not cut off power in the control box at incoming terminal board and rinse heater relay contacts. Power is still applied to them when the circuit breaker is in "off' position.

  • Page 11: Thermostat Adjustment

    THERMOSTAT ADJUSTMENT The thermostat can be adjusted by turning screw #1 (see diagram) on the thermostat housing cover. (Remember the preset setting i n case the problems are elsewhere in the control circuit.) A clockwise rotation is used to obtain a lower temperature setting and a coun- terclockwise rotation is used to obtain a higher temperature setting.

  • Page 12: Rinse Tank Heater System

    RINSE TANK HEATER SYSTEM The rinse tank heater system is electrically connected in the circuit and is controlled by a heat switch (mounted on the front panel) and a thermostat (mounted near the right front leg underneath) which activates the coil on the heat relay, mounted in the control box. When higher temperature is required, power is applied to the heaters (mounted on the right end of built in boosters) when the contacts of the heat relay are closed.

  • Page 13: Wash Tank Heater System

    WASH TANK HEATER SYSTEM The wash tank heater control system is electrically connected in the circuit to operate on 208-230 Volts. The heat circuit is controlled by a heat switch (mounted right front panel), water level control (mounted top inside control box), and thermostat (mounted right front leg underneath).

  • Page 14: Water Level Control

    WATER LEVEL CONTROL This water level control is used on this machine in conjunction with a sensor, master switch, thermostat all of which help control the action of the wash tank heater. The wash heater water level control is energized when the master switch is turned on. When the water level decreases in the wash tank, the sensor (probe) sends a signal to the control which deactivates the Plug-in relay (located on the control circuit board).

  • Page 15: Water Level Control (Aprb)

    WATER LEVEL CONTROL (AS USED ON AN APRB) The water control is used on this machine in conjunction with a sensing probe, to detect the water level in the rinse tank, and to con- trol the automatic refilling of it. When the water level decreases as the rinse pump starts to push water through the rinse tubes, the probe then sends a signal to the control which deactivates the Plug-in relay (located on the control circuit board).

  • Page 16: Replacing Seal And Ceramic On Wash And Rinse Pumps

    REPLACING SEAL AND CERAMIC ON WASH AND RINSE PUMPS The pump is part of the total motor-pump system and utilizes one seal and ceramic to prevent the pump from leaking around the impeller and shaft. One gasket is used to prevent leakage in between the pump and mounting plate and the machine pump plate. REPLACEMENT of SEAL and/or CERAMIC.

  • Page 17: Troubleshooting

    TROUBLESHOOTING SECTION Problem: Nothing on the machine operates. 1. No voltage to the dishmachine. Check to see if the customer’s fuse has blown or the circuit breaker has tripped. Replace or reset. 2. Machine circuit breaker tripped or turned off. Turn on or reset. 3.
  • Page 18 TROUBLESHOOTING SECTION (CONTINUED) Problem: Vacuum breaker leaks. 1. Limed up. To disassemble: Use flat jaw wrench or channel locks. Remove the poppet. Clean poppet, top, and body. Reassemble parts removed. 2. Faulty. Replace needed parts or whole vacuum breaker. Problem: Wash arms spray water but do not rotate. 1.
  • Page 19 TROUBLESHOOTING SECTION (CONTINUED) Problem: None of the automatic functions work (wash, rinse). 1. Start switch faulty. Check switch. Replace if necessary, see instructions page concerning replacement of switches in control panel. 2. Wire connections poor. Correct the connection. 3. Timer rinse or wash microswitch faulty. See instructions page concerning timer and motor. Problem: Rinse does not work when manual rinse fill switch operated, but does work during automatic cycle.
