SECTION 1 - INTRODUCTION 1 INTRODUCTION 1.1 Overview of Equipment The Meiko Model DV 120.2 is a commercial dishwasher/pot and pan washer. It is designed for cleaning dishes, glassware, trays, cutlery, pots, pans and kitchen utensils with a minimum of employee intervention or supervision. The DV 120.2’s Variotronic™ control system allows easy selection of three different dishwashing cycles.
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 120.2 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 3-7. 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 3-8. 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 3-10. 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 3-8. 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. Check that the rinse additive and detergent are compatible with the unit. In particular, a commercial (not a domestic) detergent MUST be used. 2 Check that the containers/dispensers are correctly installed according to the manufacturer’s instructions. 3.
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 The DV 120.2 can be positioned in either of two tabling configurations; straight through, or in a corner installation. See Figure 3-15. 1. IF the machine will be positioned in a corner, perform the following steps before attaching the tables: • Position the machine so that the LEFT REAR corner of the machine faces the corner of the wall, as shown in Figure 3-15.
SECTION 3 - INSTALLATION CAUTION After adjusting the height of the machine, always check that it is level to ensure proper operation. 3. Position each table lip-in at the machine, as shown in Figure 3-17. Be sure to seat the lip-in against the inner, vertical mounting surface. CAUTION If the table lip-in extends beyond the vertical mounting surface, and down to the angled face of the inside of the machine, it will not seat properly.
SECTION 3 - INSTALLATION 3.14 Final Assembly 1. Check and tighten all electrical terminal screws. 2. Replace all panels onto the machine. 3. Switch the circuit breaker/fused disconnect to the ON position. Be sure to prime the detergent pumps and check for correct chemical concentration before operating the unit. 3.
SECTION 4 - OPERATION 4 OPERATION 4.1 Location and Description of Controls The machine controls are on the keypad on the front panel. See Figure 4-1.
SECTION 4 - OPERATION 4.2 Startup 4.3 Loading Check the level of the external detergent and rinse additive dispensers. If necessary, replace or refill the dispensers. The loading guidelines shown here will lead to faster, more efficient cleaning of your ware. Press any of the three POWER/VARIOTRONIC CYCLE SELECT keys to turn on the machine. Load plates, soup bowls, etc. at an angle with the inside face pointing up. Ensure that water cannot pool in the bottom of bowls.
SECTION 4 - OPERATION Do not stack items in the dishwasher. Stacked items require longer or multiple cleaning cycles because the wash water cannot reach the food residue as effectively. It is more efficient to load the dishwasher with fewer items and run multiple, shorter cycle times. 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/ VARIOTRONIC CYCLE SELECT key has stopped flashing.
SECTION 5 - CLEANING 5 CLEANING WARNING! Before ANY cleaning, check that the circuit breaker/fused disconnect is in the OFF position and that the unit is switched off. IMPORTANT The headings Daily Cleaning and Weekly Cleaning in this section are general recommendations based on typical soiling. Because of the large quantity of food soiling present on many pots and pans, it may be necessary to clean the machine more often and more extensively than a traditional dishwasher.

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 by placing a service call. Info Codes appear for minor difficulties. Error codes appear for more complex issues.
