INTRODUCTION INTRODUCTION Welcome to Moyer Diebel. Thank you for choosing Moyer Diebel and for allowing us to take care of your glasswashing/ warewashing needs. This manual covers two models (MD 18-1, MD 18-2). Model numbers are shown on the front cover. Your machine has been completely assembled, inspected, and thoroughly tested at our factory to eliminate problems at installation before it was shipped to your installation site.
GENERAL GENERAL This manual covers the Moyer Diebel automatic glasswashing machine.
GENERAL Electrical Power Requirements Model MD18-1 MD18-2 Voltage 115/60/1 115/60/1 Booster Rise N/A N/A Machine Full Load Amp 12 12 Power Requirement (125% Service Factor) 15 15 NOTE: All machines come with a 5 Foot cord and plug. Standard 15 amp receptacle required.
INSTALLATION INSTALLATION Unpacking ! WARNING: Care should be taken when lifting the machine to prevent damage. 1. Immediately after unpacking your machine, inspect for any shipping damage. If damage is found, save the packing material and contact the carrier immediately. 2. Remove the glasswasher from the skid. Adjust the feet if required, then move the machine to its permanent location. 3.
INSTALLATION Plumbing Connections ! CAUTION: Plumbing connections must comply with local sanitary and plumbing codes. Water Connections 1. Connect the hot water supply (140oF/60oC Min) to the fill solenoid valve (located behind the front panel). The fill solenoid valve is equipped with a flow control that will accept water pressures from 20 psi to 70 psi. 2. Install a manual shut-off valve in the water supply line to accommodate servicing the machine.
INSTALLATION Completing Installation 1. Remove any foreign material from inside the machine. 2. Check to assure scrap basket and sump cover are in place. 3. After plumbing and electrical connections are completed, check the machine for water leaks by depressing the ON/FILL switch on the front panel, then close and latch the door(s). This allows the tank to fill and to complete the rinse cycle. Check for leaks. 4. Open the door and check the water level.
OPERATION OPERATION Operation Summary The following is a summary of your Glasswashing Machine operating cycle: 1. The cycle begins when you close the door and push the cycle switch. 2. The green cycle lamp lights and the pump starts. 3. The pump runs during the wash cycle. 4. The pump stops, and the drain valve is opened. 5. After a 2-3 second pause, the pump drain cycle begins. 6. After a 2-3 second pause, the fill valve opens, and the pump starts for the rinse cycle. 7.
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. 7. The pump will automatically stop and the green cycle light will turn off indicating the cycle is completed. 8. Open the door and remove the rack. 9. Repeat steps 4-9 for additional cycles. 10. CLEAN the scrap basket after every use period. During heavy usage, the scrap basket should be cleaned more frequently.
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.
MAINTENANCE Deliming Your glasswasher should be delimed regularly as required. This will depend on the mineral content of your water. Inspect your machine interior for lime deposits. If deliming is required, a deliming agent should be used for best results. ! DANGER: Deliming solution or other acids must not come in contact with household bleach (sodium hypochlorite) or any chemicals containing chlorine, iodine, bromine, or fluorine. Mixing will cause hazardous gases to form.
MAINTENANCE Maintenance Schedule • • 12 As Required 1. Check the temperature gauge reading. 2. Check the chemical supplies and refill as necessary. Weekly 1. Inspect all water lines for leaks and tighten them at joints if required. 2. Clean all detergent residue from the exterior of the machine. 3. Check the drain for leaks. 4. Clean accumulated scale from the heating element. 5. Remove and closely inspect each spray arm for blockage. 6. Check for damage to the scrap screen.
TROUBLESHOOTING TROUBLESHOOTING Before determining any specific cause of a breakdown or abnormal operation of your glasswasher, check that: 1. All switches are ON. 2. Wash arms are clean. 3. Scrap screen is properly positioned and clean. 4. Thermostat(s) are at their correct setting. 5. Sanitizer, detergent, and rinse additive dispensers are adequately filled. 6. All plumbing valves are open. If a problem still exists, use the following table for troubleshooting.
