3 INSTALLATION

3.1 Overview of InstallationThe owner should contract with qualifiedpersonnel to move the appliance to theinstallation location, unpack it, and prepare itfor final utility connections. In most cases,local codes prevent the final utility connectionsfrom being made by any party other than alicensed electrician and/or plumber.IMPORTANTIt is the responsibility of the owner to ensurethat all aspects of the installation comply withall applicable local and national codes.IMPORTANTThe appliance’s warranty is not valid until aMeiko Authorized Service Agent performs aStartup and Demonstration on the appliance.This Demonstration should be scheduled afterinstallation.Installation of the dishwasher involves thefollowing steps:• Verifying that the utility connections are

present, are appropriate for the appliance,and comply with all applicable local andnational codes.

• Unwrapping the appliance (leaving theshipping skid in place for easier move-ment) and checking for shipping damage.

• Moving the appliance to the installationlocation, removing the skid, and levelingthe feet.

• Connecting the electrical supply.• Installing the chemical dispensing system.

For units equipped with the optionaldispensing system, this involvesconnecting the warewasher’s detergent andrinse additive tubes to appropriate dispensers.For units without the optional system, thedispensing system installer should followthe manufacturer’s instructions AND theinstructions in Section 3 of this Manual.

• Connecting the fresh water supply.• Positioning the drain hose.• Connecting the machine to tabling.

• Contacting your Meiko Authorized ServiceAgent to perform a Startup andDemonstration on the appliance. This stepalso validates the appliance’s warranty.

3.2 Requirements Before InstallationBefore the installer can uncrate and move theappliance to the installation location, thefollowing conditions MUST be met:• INSTALLATION AREA REQUIREMENTS

- The area MUST be frost-free. Freezingtemperatures (32°F/0°C or lower)inhibit proper operation and candamage internal components.

- The area MUST have a firm floorsurface. It is possible to compensate foruneven flooring by adjusting the feet.

- The area should be away fromappliances, furniture or surfaces thatcan be damaged by steam. If this isnot possible, these items should beprotected from the small quantities ofsteam that are released during normaloperation of the dishwasher.

• UTILTITY CONNECTION REQUIREMENTS- Connections must be present and

ready for hookup to the appliance. Allutility supplies must comply with theelectrical information labels, with theinformation on the data plate, and withall applicable local and national codes.

3.6 Dispensing system overview

The DV 200.2 is designed for usewith a liquid rinse aid, and eithersolid or liquid detergents.Units equipped with optional liquidinternal detergent and rinse aidpumps have two tubes exiting themachine at the lower rear. Thesetubes can simply be attached todetergent and rinse aid containers.See Figure 3-7.Units that are NOT equipped withthe internal pumps have:• A blue rinse aid line exiting the

machine at the lower rear.• Two dummy plugs covering

holes in the back of the washtank that can be used for de-tergent injection. The plugs areaccessed by removable panelson the sides of the machine.Either plug can be used.

• A hole in the bottom of the washtank for the installation of a de-tergent concentration probe.

A dispensing system terminal block(shown in Figure 3-7) providescontacts for two line voltagerelays. These relays, when closed,provide a “window” for externalpump systems to activate.• The rinse aid pump relay closes

for approximately 16.5 secondswhenever the booster tankrefills (once per cycle).

• The detergent pump relaycloses whenever the washpump is in operation.

Activation of the pumps can becontrolled as follows:• Solid detergent systems should

use a detergent concentrationprobe installed in the wash tankto activate the external pump.A dummy plug at the bottom ofthe wash tank provides aninstallation location for the probe.

3.8 Installing an External Liquid Rinse AidSystem

A pre-plumbed, blue 1/4” ID tube at the lowerrear of the unit serves as the connection pointfor 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, closeand seal it with the plug and wire clamp thatare supplied on the end of the tube. SeeFigure 3-8.To install a liquid rinse aid dispensing system:1. Route the rinse aid supply line to the blue

1/4” ID tube at the lower rear of themachine.

2. Fasten the line in place and seal theconnection.

3. Check that the pump is correctly installedaccording to the manufacturer ’sinstructions.

3.9 Wiring External Chemical DispensingSystems

IMPORTANTSome local codes dictate that electricalconnections be made only by a certifiedprofessional.1. Locate the chemical dispenser terminal

block. See Figure 3-3.2. Thread the incoming leads from the

chemical pumps through the extra strainreliefs (at the lower rear of machine) andto the chemical dispenser terminal block.

3. Connect the wires as shown in Figure3-11. Note that the terminal block suppliesLINE VOLTAGE SIGNALS. An additionaltransformer may be required dependingon the supply requirements of the externalpumps.

4. Adjust the strain reliefs to fasten the wiringin place. Leave enough slack in the wiringto prevent stress on the terminalconnections. Bundle the wires togetherusing wire ties to prevent them fromtangling when repositioning the appliance.

3.10 Connecting Chemical Containers orDispensers (if so equipped)

This section applies to units with eitherinternal or external chemical dispensingpumps.1. Check that the rinse additive and

detergent are compatible with the unit. Inparticular, a commercial (not a domestic)detergent MUST be used.

2 Check that the containers/dispensers arecorrectly installed according to themanufacturer’s instructions.

3. If the dishwasher is equipped with factoryinternal chemical dispensing pumps, twostrainer assemblies for the chemicalcontainers are also included. See Figure3-12. These strainers should beassembled onto the lids for the detergentand rinse additive containers.

4. For liquid detergent systems, locate theCLEAR liquid detergent tube. Connect thetubing to the detergent container.For solid detergent systems, connect thedetergent supply line according to themanufacturer’s instructions.

5. Locate the BLUE liquid rinse additive tubeat the lower rear of the unit. Connect thetubing to the rinse additive container.

6. If using the strainers shown in Figure3-12, be sure to use the supplied wireclamps to fasten the chemical supplytubes securely. Meiko STRONGLYRECOMMENDS the use of a sealingcompound on these connections toprevent leakage.

3.11 Fresh Water Supply ConnectionCAUTIONBefore connecting the water supply hose, theline MUST be flushed clean of all debris,including (but not limited to) pipe sealant,metal particles, solder, etc. This debris candamage the appliance.IMPORTANTIn some cases, local codes dictate that watersupply connections be made only by acertified professional.1. Check that iron or other metal particles

cannot contaminate the fresh watersupplied to the dishwasher.

2. Check that the incoming water pressureis within the acceptable range for theappliance (14.5-72.5 psi, 1.0-5.0 bars). Itmay be necessary to increase the pres-sure (with a booster pump) or to reducethe pressure (with a reducing valve).

3. Check the incoming water temperature.Meiko recommends a water temperatureof 140°F/60°C for optimum operation,although if necessary the appliance willoperate correctly using water at anytemperature of 140°F/60°C or lower.Colder water will result in a longer preheattime (during initial startup) and may extendthe cycle time to allow the final rinse waterto heat to 180°F/82°C.

4. Check the incoming water hardness.Meiko recommends a hardness of 4 grainsper U.S. gallon (7 DH German hardness).

5. Because the water inlet incorporates astainless steel dirt trap, an additional trapis unnecessary unless required by local,national or international codes.

6. The dishwasher includes a water supplyline that ends in an enclosure containingthe water inlet valve and the Aqua-Stopshutoff valve (see Figure 3-13). Connectthe customer-supplied water line to thefitting on the end of this enclosure. Use asealing compound on the threads to ensurethat no leaks are present in the connection.

7. Check that the water line is long enoughto permit the unit to be repositioned forservicing.

3.12 Drain Hose Positioning1. Check that the end of the drain hose will

empty into a drain with a minimumdiameter of 1-1/2”/38mm.

2. Check the type of drain that will be used.Because the DV 200.2 uses a pumped drain,either a floor or wall drain is acceptable.CAUTIONNo portion of a wall drain system may behigher than 24” (610m) A.F.F. to ensurethat the drain pump is operating withinrated specifications. See Figure 3-14.

3. Route the drain hose to the drain. In somecases, a grease trap (supplied by others)must be fitted into the waste water line. Ifthis trap is required for your installation,check that it is present.

3.13 Tabling AttachmentThe DV 200.2 can be positioned ineither of two tabling configurations;straight through, or in a cornerinstallation. See Figure 3-15.1. IF the machine will be

positioned in a corner, performthe following steps beforeattaching the tables:• Position the machine so that

the LEFT REAR corner ofthe machine faces thecorner of the wall, as shownin Figure 3-15. For cornerinstallations, this placementis necessary to ensure thatthe control panel can bereached by the operator.

• Remove the FRONT LEFTrack guide as shown inFigure 3-15. The guide isheld in place by two screws.Replace the guide on theLEFT SIDE position in the2 mounting holes provided.

2. Position the machine and tablesas follows:• Check that the centerline of

the opening at the end ofeach table is aligned withthe centerline of the racktrack of the machine. SeeFigure 3-16.

• Check that the surfaceheight of each tablematches the height of therack track of the machine,to ensure a smooth transi-tion. The standard table sur-face height is 34” (864mm).

• Check that the machine islevel.

The height of the machine, andof most tables, can be adjustedby rotating the feet at the endof the legs.

CAUTIONAfter adjusting the height of the machine,always check that it is level to ensureproper operation.

3. Position each table lip-in at the machine,as shown in Figure 3-17. Be sure to seatthe lip-in against the inner, vertical mount-ing surface.CAUTIONIf the table lip-in extends beyond thevertical mounting surface, and down to theangled face of the inside of the machine,it will not seat properly. The lip-in shouldbe no more than 3/4” (19mm) in depth toensure correct mounting to the machine.

4. For corner installations, check that thesides of the front table do not prevent thedoor handle from being pushed down farenough to engage the door switch. Bypushing the handle slowly, you shouldhear an audible “click” as the switchengages.If it is necessary to trim the table sides toclear the handle and allow the switch toengage, refer to Figure 3-18.

5. After the tables have been positionedcorrectly, secure them to the machineusing silicone sealant.

3.15 Priming the Detergent and RinseAdditive Lines

For machines equipped with externalchemical dispensing systems, prime thedetergent and rinse additive lines accordingto the manufacturer’s instructions.

For machines equipped with factory internalchemical dispensing systems, prime the linesas follows:

1. Press and hold the key until appears in the display

(about 4-5 seconds).

2. Press the key 5 times until appears in the display.

3. Press the key. willappear in the display.

4. Press the key to start priming the liquidrinse additive lines. A timer will count downthe time remaining. By default, the systemwill prime for 180 seconds.

5. When the display returns to, press the key so

that appears in thedisplay.

6. Press the key to start priming the liquiddetergent lines. A timer will count downthe time remaining. By default, the systemwill prime for 30 seconds.

7. When the display returns to, press the key to

shut off the dishwasher.

3.16 Checking for Correct ChemicalConcentration

Machines equipped with external chemicaldispensing systems will have normal settingsrecommended by the manufacturer.For machines equipped with factory internalchemical dispensing systems, the normalsettings for chemical injection are:• Detergent - 0.256 oz. per gallon of wash

water (2.0 ml per liter).• Rinse additive - 0.0256 oz. per gallon of

rinse water (0.2 ml per liter).To check if the normal settings are correct foryour chemicals, RUN THREE EMPTYLOADS to completely cycle the water supplyand obtain accurate test results. This will onlytake a few minutes. Then, run a sample loadwith soiled ware and examine the results.• If the detergent setting is too low, the ware

will not be adequately cleaned. In somecases, this can be corrected by simplyselecting a longer cycle time (using theCycle Select II, Medium or Cycle SelectIII, Heavy buttons), but the detergentconcentration may also need to be adjusted.

• If the rinse additive setting is too low,spotting or streaking may occur on theware.

• If too much of either chemical is added,the extra chemicals will be wasted. Thisis often difficult to detect except bydetermining how long your chemicalsupplies last. If the chemicals are beingexhausted quickly, you may need to havethe chemical concentration adjusted.

IN ALL CASES, ANY ADJUSTMENTS OFTHE FACTORY CHEMICAL INJECTIONSETTINGS ARE TO BE PERFORMED

ONLY BY A MEIKO AUTHORIZEDSERVICE AGENT. CHANGES BY

UNAUTHORIZED PERSONNEL WILLVOID YOUR WARRANTY.

If you need to contact your AuthorizedService Agency, please contact MeikoTechnical Support at 1-800-868-3840.


3.14 Final Assembly1. Check and tighten all electrical terminal

screws.2. Replace all panels onto the dishwasher.3. Switch the circuit breaker/fused

4.2 Startup

The light above the selectedPOWER/CYCLE SELECT key willbegin to flash, showing that the tankis filling and the water is heating tothe correct temperature.

The time required for filling and preheatingwill vary based on the temperature of theincoming water supply. For incoming waterat 140°F/60°C, the machine may need up to15 minutes to fill and heat to the correct washtemperature. The default wash temperatureis several degrees above 150°F/66°C forefficient operation.

Press any of the three POWER/CYCLESELECT keys to turn on the dishwasher.

Normal cycle for typically soileditems

Extended cycle for items withgreater soiling

(constant)

OPTIONAL

When the tank is full and the waterhas been heated to the correcttemperature, the light above theselected POWER/CYCLE SELECTkey will stop flashing. Thedishwasher is now ready foroperation.

Check the level of the external detergent andrinse additive dispensers. If necessary,replace or refill the dispensers.

4.3 Loading

The loading guidelines shown here will leadto faster, more efficient cleaning of your ware.

Load hollow or concave dishware (glasses,large bowls, etc.) upside-down and at anangle. This allows water to drain more quickly,preventing stains.

For greater efficiency in loading cutlery, youcan use cutlery holders. When loading them:• Do not overload the holders.• Always load knives, forks and

spoons with the handleDOWN.

• Do not load identical wareinto any given holder.Instead, load an assortmentof knives, forks and spoonsinto each holder. Identicalware is often too closelyspaced for effective cleaning.

Do not stack items in the dishwasher. Stackeditems require longer or multiple cleaningcycles because the wash water cannot reachthe food residue as effectively. It is moreefficient to load the dishwasher with feweritems and run multiple, shorter cycle times.

Load plates, soup bowls, etc. at an angle withthe inside face pointing up. Ensure that watercannot pool in the bottom of bowls.

Position bowls toallow water to drain

WARNING!If the door is opened suddenly, hot

water can spray out of the dishwasher. Toprevent this from happening:• Open the door slowly until the dishwasher
