SECTION 1 - INTRODUCTION 1 INTRODUCTION 1.1 Overview of Equipment The Meiko Model DV 270.2 is a commercial pot and pan washer/dishwasher. It is designed for cleaning pots, pans, trays, kitchen utensils, cutlery, dishes and glassware with a minimum of employee intervention or supervision. A control keypad allows easy selection of three different washing cycles to accommodate different types of ware and levels of soiling. A digital display permits easy monitoring of operation.
SECTION 3 - INSTALLATION 3 INSTALLATION 3.1 Overview of Installation The owner should contract with qualified personnel to move the appliance to the installation location, unpack it, and prepare it for final utility connections. In most cases, local codes prevent the final utility connections from being made by any party other than a licensed electrician and/or plumber.
SECTION 3 - INSTALLATION 3.3 Uncrating, Positioning and Leveling 1. Remove all shipping and packaging material from the appliance, including supports and wrappings. Leave the shipping skid in place at this time to allow for easier movement to the installation location. 2. Check for shipping damage as described in Section 2, “Transport and Shipping.” If damage is present, call Meiko Customer Service at 1-800-868-3840, providing full details on the customer, serial number and extent of damage present.
SECTION 3 - INSTALLATION 3.5 Main Electrical Supply Connection WARNING! Check that the circuit breaker/fused disconnect is in the OFF position and that the unit is switched off before making the electrical utility connections. IMPORTANT In some cases, local codes dictate that electrical supply connections be made only by a certified professional. 1. Check that the incoming power leads are of sufficient rating for the appliance’s current draw.
SECTION 3 - INSTALLATION 3.6 Dispensing system overview The DV 270.2 is designed for use with a liquid rinse aid, and either solid or liquid detergents. Units equipped with optional liquid internal detergent and rinse aid pumps have two tubes exiting the machine at the lower rear. These tubes can simply be attached to detergent and rinse aid containers. See Figure 3-6. Units that are NOT equipped with the internal pumps have: • A blue rinse aid line exiting the machine at the lower rear.
SECTION 3 - INSTALLATION CAUTION If the unit will NOT use one or both of the chemical supply tubes, cut the unused tube(s) close to the point where it exits the machine’s exterior panel and seal it using the supplied plug and wire clamp. See Figure 3-7. For units equipped with the optional internal chemical dispensing system, skip ahead to Section 3.10, “Connecting Chemical Containers or Dispensers.” 3.7 Installing an External Detergent System To install a detergent dispensing system: 1.
SECTION 3 - INSTALLATION 3.8 Installing an External Liquid Rinse Aid System A pre-plumbed, blue 1/4” ID tube at the lower rear of the unit serves as the connection point for the rinse aid supply. See Figure 3-9. If a liquid rinse aid system will NOT be used, cut the tubing near the rear panel. Then, close and seal it with the plug and wire clamp that are supplied on the end of the tube. See Figure 3-7. To install a liquid rinse aid dispensing system: 1.
SECTION 3 - INSTALLATION 3.10 Connecting Chemical Containers or Dispensers (if so equipped) This section applies to units with either internal or external chemical dispensing pumps. 1.

SECTION 3 - INSTALLATION 3.11 Fresh Water Supply Connection CAUTION Before connecting the water supply hose, the line MUST be flushed clean of all debris, including (but not limited to) pipe sealant, metal particles, solder, etc. This debris can damage the appliance. IMPORTANT In some cases, local codes dictate that water supply connections be made only by a certified professional. 1. Check that iron or other metal particles cannot contaminate the fresh water supplied to the dishwasher. 2.
SECTION 3 - INSTALLATION 3.13 Tabling Attachment 1. Position the machine and tables as follows: • Check that the centerline of the opening at the end of each table is aligned with the centerline of the basket track of the machine. See Figure 3-14. • Check that the surface height of each table matches the height of the basket track of the machine, to ensure a smooth transition. The standard table surface height is 34” (864mm). • Check that the machine is level.
SECTION 3 - INSTALLATION 3.14 Final Assembly 1. Check and tighten all electrical terminal screws. 2. Replace all panels onto the machine. 3.

Be sure to align the racks with the locator guides in the bottom of the wire basket. Glasses loaded with the open side facing DOWN Locator guides Glassware rack Two 20x20” racks OR Rack with hold-down grid For greater efficiency in loading cutlery, you can use cutlery holders.
SECTION 4 - OPERATION 4.4 Operation Press the CYCLE/DRAIN key to begin the selected cycle. The key will not work unless the light above the selected POWER/ CYCLE SELECT key has stopped flashing. The machine will begin a wash and rinse cycle. The Soft Start feature pumps the water through the arms slowly for the first few seconds of the cycle to protect fragile ware. After a few seconds, full pressure will engage. The time of the total cycle will be at least as long as the times shown in Section 4.1.
SECTION 5 - CLEANING 5 CLEANING 5.1 Daily Cleaning (or as required) 1. The machine automatically enters a selfcleaning cycle when it is turned off. The interior will be sprayed with hot, fresh water as the booster tank empties. 2. AFTER this cycle ends and the machine shuts down, open the door, and wheel the basket out of the machine. Any food soil clinging to corners, etc. of the basket can be wiped off with a clean, damp cloth. 3.
SECTION 5 - CLEANING 2. Remove and disassemble the wash and rinse arms. The machine is equipped with: • Five upper wash arms (identical) • Five lower wash arms (identical) • Two removable upper rinse arms (identical) • Two removable lower rinse arms (identical) • Two additional fixed lower rinse arms (leave these in place) All four removable rinse arms are identical. The upper wash arms are slightly longer than the lower arms to prevent their reinstallation in the wrong location.
SECTION 5 - CLEANING 5.3 Exterior cleaning (as required) 5.4 Deliming (as required) CAUTION When cleaning the exterior of the machine, be sure to follow these guidelines: • Meiko strongly recommends using detergent when cleaning the exterior of the unit, instead of commercial stainless steel cleaners. These cleaners can damage the surface of the control panel. • Never use abrasive cleaners or pads when cleaning the exterior of the machine. These can scratch the surface of the unit.
SECTION 6 - TROUBLESHOOTING 6 TROUBLESHOOTING If the machine encounters a problem, an Info Code or Error Code will usually appear in the display. If you use this troubleshooting guide to resolve simple problems, you can often return the appliance to operation faster than placing a service call. Info Codes appear for minor difficulties. Error codes appear for more complex issues. After correcting the condition, if the unit does not return to normal operation automatically, press or to clear the message.
