  • Page 8: General

  • Page 10: Installation

    Immediately after unpacking your machine, inspect for any shipping damage. If damage is found, save the packing material and contact the carrier immediately. Remove the dishwasher from the skid. Adjust the feet if required, then move the machine to its permanent location.

  • Page 11: Plumbing Connections

    Have your chemical supplier check the concentration and make the necessary adjustments. NOTE: A nonchlorinated detergent is recommended for your dishwasher. Rinse Aid An optional rinse aid pump may be added for all models. Insert the labeled Rinse Aid pickup tube into the rinse aid container.

  • Page 12: Completing Installation

    To prime the booster, the following procedure must be followed AFTER the electrical and plumbing connections have been made and water has been turned on. Open the dishwasher door. Make sure the On-Fill/Off-Drain switch is in the Off-Drain position. Push the Detergent/Rinse prime switch “down” to the Rinse position.

  • Page 13: Operation

    Daily Operation Procedures The operation of your dishwasher will be more efficient when these procedures are followed: Check that the spray arm and scrap screen are in place. Close and latch the door. Push the ON/FILL switch to the ON position. The tank will begin filling with water.
  • Page 14 OPERATION NOTE: The machine may be stopped at any time by opening the door. When restarted, the cycle does not start over. It will continue from the point at which it was interrupted. Check the rinse temperature during the final rinse (120 seconds into cycle). The rinse temperature must be 82°C/180°F minimum for model I-UH.

  • Page 15: Maintenance

    MAINTENANCE The efficiency and life of your machine is increased by regularly scheduled preventive maintenance. A well maintained machine gives better results and service. An investment of a few minutes of daily maintenance will be worthwhile. The best maintenance you can provide is to keep your machine clean. Components that are not regularly cleaned and flushed will clog and become inoperative.

  • Page 16: Deliming

    The dishwasher will complete a regular cycle. Check the deliming results and repeat if necessary per the chemical supplier’s specifications. Operate the dishwasher for at least four complete cycles to purge the machine of any deliming chemicals. Drain the dishwasher. Deliming is complete.

  • Page 17: Maintenance Schedule

    Maintenance Schedule • As Required Check the temperature gauge reading. Check the chemical supplies and refill as necessary. • Weekly Inspect all water lines for leaks and tighten them at joints if required. Clean all detergent residue from the exterior of the machine. Check the drain for leaks.

  • Page 18: Troubleshooting

    TROUBLESHOOTING TROUBLESHOOTING Before determining any specific cause of a breakdown or abnormal operation of your dishwasher, check that: Power supply is turned on. All switches are ON. Wash arm is clean. Scrap screen is properly positioned and clean. Thermostat is at the correct setting.
