Page 11: Installation
INSTALLATION Unpacking WARNING: Care should be taken when lifting the machine to prevent damage. 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 glasswasher from the skid. Adjust the feet if required, then move the machine to its permanent location. -
Page 12: Plumbing Connections
Drain Connections Your Moyer Diebel glasswasher is supplied with a flexible 5/8" I.D. drain hose, which must be connected to a 1-1/2" drain using a wye (Y) fitting. Additional drain hose may be purchased from a Moyer Diebel parts distributor. -

Page 16: Maintenance
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 17: Deliming
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. -
Page 18: Maintenance Schedule
MAINTENANCE 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. -

Do you have a question about the MD18-1 and is the answer not in the manual?
Questions and answers
I have a much older MD-18 and the heat element corroded out , I went to replace it only to find it was a 220/240 volt HE which was installed in a 110/120 volt unit..? Was this the original idea by MoyerD.? Or did maybe someone replace with WRONG heat element during a service situation? This unit ran fine until the HE fried.. was that machine designed for a 220/240 v heater? TY
