Other features of the unit that affect operationinclude:

Auto Safe - An internal booster heater isregulated by the electronic control system toensure a proper sanitizing final rinsetemperature, regardless of the incoming watertemperature.

Soft Start - The wash water is pumped at areduced pressure for the first few seconds ofthe wash cycle. This protects the ware frombeing moved or damaged by a sudden burstof pressure.

Pumped Rinse - An internal rinse pumpensures that the final rinse pressure isconstant.

Pumped Drain - Accommodates wall or floordrains.

Aqua Stop - The unit will automatically shutdown if a water leak is detected.

For efficient and SAFE operation, be sure tofollow the installation and operatinginstructions provided in this manual. Inparticular, all safety symbols and notices onthe equipment and in the supplieddocumentation must be followed.

IMPORTANTThe Model FV 40.2 dishwasher has beendesigned exclusively for the washing ofdishes, glassware, cutlery and kitchen utensilsin a commercial or institutional setting andmust not be used for any other purpose.

3 INSTALLATION

3.1 Overview of Installation

The 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 arepresent, 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.

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

3.2 Requirements Before Installation

3.3 Uncrating, Positioning and Leveling

CAUTIONDuring shipping and installation, the dishwashermay ONLY be positioned upright or on its left side.Some water may remain in the lines after pre-shipping testing. If the unit is positioned in anymanner EXCEPT upright or on its left side, this watercan affect the operation of the water level sensor.

1. Remove all shipping and packaging materialfrom the appliance, including supports andwrappings. Leave the shipping skid in place atthis time to allow for easier movement to theinstallation location.

2. Check for shipping damage as described inSection 2, “Transport and Shipping.” If damageis present, call MEIKO Customer Service at1-800-868-3840, providing full details on thecustomer, serial number and extent of damagepresent. MEIKO will file a freight claim based onthis information.

3. Move the appliance to the installation area andremove the skid. Use caution to avoid damagingthe appliance or any of its components.

4. Check that the plastic feet are attached to eachof the four adjustable leg bolts. If necessary,attach them by pressing them firmly onto theend of the bolts.

5. Using a spirit level, check that the appliance islevel in both directions (front-to-back AND side-to-side). If necessary, rotate the leg bolts to levelthe appliance.

CAUTIONThe dishwasher MUST be level for properoperation.

3.4 Accessing the UtilityConnections

In order to attach the utility connections,the back panel of the dishwasher mustbe removed. Follow the steps below.

1. Remove AND RETAIN the threeretaining screws underneath thebottom lip of the rear panel. SeeFigure 3-1.

2. Carefully slide the rear panel downto free the retaining clips along thetop edge. See Figure 3-2.

3. Remove the rear panel from thedishwasher.

3.5 Main Electrical Supply Connection

WARNING!Check that the circuit breaker/fuseddisconnect is in the OFF position andthat the unit is switched off beforemaking the electrical utility connections.

IMPORTANTIn some cases, local codes dictate thatelectrical supply connections be made onlyby a certified professional.

1. Check that the incoming power leads areof sufficient rating for the appliance’scurrent draw. Amperage and minimumsupply wire specifications are shown onthe serial plate and on the electricalinformation label.

2. Check that the incoming power leads arelong enough to permit the unit to berepositioned for servicing.

3. Locate the strain relief for the electricalsupply wiring at the lower rear of themachine (Figure 3-3). Thread the incomingsupply leads through the strain relief andto the main electrical supply terminal block.

4. Refer to Figure 3-4 and to the electricalwiring diagram. Connect the power supplyand ground leads as indicated.

5. Adjust the strain relief to fasten the wiringin place. You should leave enough slackin the wiring to prevent stress on theterminal connections.

3.6 Dispensing system overview

The FV 40.2 is designed for use with liquiddetergent and liquid rinse additive. The unitis not compatible with solid detergentsand/or rinse additives.

The tubes located at the lower rear of thewarewasher are pre-plumbed to supply liquiddetergent (clear tube) and liquid rinse additive(blue tube). See Figure 3-3.

Some units are equipped with optional internalliquid detergent and rinse additive dispensingpumps, in which case containers can simplybe attached to the supply tubes. Units withoutthe optional internal pumps will require the

tubes to be routed to external pumps, if theyare used.

CAUTIONIf the unit will NOT use one or both of thechemical supply tubes, cut the unused tube(s)close to the point where it exits the machine’sexterior panel and seal it using the suppliedplug and wire clamp. See Figure 3-5.

For units equipped with the optional internalchemical dispensing system, skip ahead toSection 3.8, “Connecting Chemical Containersor Dispensers.”


3.7 Installing External Chemical Pumps (if so equipped)

Figure 3-5: Sealing unused chemical tubes (if not using aliquid detergent or rinse additive)

Figure 3-6: External chemical pumpconnections

4. Connect the wires as shown in Figure3-6. Note that the terminal block suppliesLINE VOLTAGE SIGNALS. An additionaltransformer may be required dependingon the supply requirements of the externalpumps.

5. 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.

IMPORTANTSome local codes dictate that electricalconnections be made only by a certifiedprofessional.

The machine’s dispensing terminal blockincludes relays that close during specific timesin the cycle. The closed relays complete acircuit, creating a “window” that allowsactivation of external chemical dispensers.

• The rinse additive relay is closed for 16.5seconds when the booster tank begins itsfill cycle. A timer in the external systemshould be used to regulate the amount ofrinse additive injected per cycle.

• The detergent relay is closed wheneverthe wash pump is in operation.

IMPORTANTIt is HIGHLY RECOMMENDED to use atimer system to control detergent injection,NOT a detergent concentration probe.

Two pre-plumbed 1/4” ID tubes serve as theconnection points for the chemical supplies.The CLEAR tube supplies detergent, and theBLUE tube supplies rinse additive.

To install external chemical dispensers:

1. Check that the pump(s) are correctlyinstalled according to the manufacturer’sinstructions.

2. Locate the chemical dispenser terminalblock. See Figure 3-3.

3. Thread the incoming leads from thechemical pumps through the strain reliefs(at the lower rear of the machine) and tothe chemical dispenser terminal block.

4. Locate the CLEAR liquid detergent supplytube at the lower rear of the unit. Connectthe tubing to the detergent container.

5. Locate the BLUE liquid rinse additivesupply tube at the lower rear of the unit.Connect the tubing to the rinse additivecontainer.

6. If using the strainers shown in Figure 3-7,be sure to use the supplied wire clampsto fasten the chemical supply tubessecurely. MEIKO STRONGLY RECOM-MENDS the use of a sealing compound onthese connections to prevent leakage.

This section applies to units with either inter-nal or external chemical dispensing pumps.

1. Check that the rinse additive anddetergent are compatible with the unit. Inparticular, a commercial (not a domestic)LIQUID detergent MUST be used. TheModel FV40.2 is not compatible with soliddetergents and/or rinse additives.

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 Figure3-7. These strainers should be assembledonto the lids for the detergent and rinseadditive containers.


3.9 Fresh Water Supply Connection

CAUTIONBefore 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 particlescannot contaminate the fresh water suppliedto the dishwasher.

2. Check that the incoming water pressure iswithin the acceptable range for theappliance (8.7-72.5 psi, 0.6-5.0 bars). Itmay be necessary to increase the pres-sure(with a booster pump) or to reduce thepressure (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 willsanitize correctly using water at anytemperature. Colder water will result in alonger preheat time (during initial startup)and may extend the cycle time to allow thefinal rinse water to heat to 180°F/82°C.

4. Check the incoming water hardness.MEIKO recommends a hardness of 4-6grains per U.S. gallon.

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 supply linethat ends in an enclosure containing thewater inlet valve and the Aqua-Stop shutoffvalve (see Figure 3-8). Connect thecustomer-supplied water line to the fittingon the end of this enclosure. Use a sealingcompound on the threads to ensure that noleaks are present in the connection.

7. Check that the water line is long enough topermit the unit to be repositioned forservicing.

3.10 Drain Hose Positioning

1. Check that the end of the drain hose willempty into a drain with a minimum diameterof 1-1/2”/38mm.

2. Check the type of drain that will be used.Because the FV 40.2 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 3-9.

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.

3.12 Priming the Detergent and RinseAdditive Lines

For machines equipped with external chemicaldispensing systems, prime the detergent andrinse additive lines according to themanufacturer’s instructions.

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

1. Press and hold the STOP/OFF (O) key until appears in the display

(about 4-5 seconds).

2. Press the START/DRAIN ( )key 5 timesuntil appears in the display.

3. Press the key. willappear in the display.

4. Press the START/DRAIN ( )key to startpriming the liquid rinse additive lines. Atimer will count down the time remaining.By default, the system will prime for 180seconds.

5. When the display returns to, press the key so that appears in the display.

6. Press the START/DRAIN ( )key to startpriming the liquid detergent lines. A timerwill count down the time remaining. By default,the system will prime for 30 seconds.

7. When the display returns to, press the STOP/OFF

(O) key to shut off the dishwasher.

3.13 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 washwater (2.0 ml per liter).

• Rinse additive - 0.0256 oz. per gallon ofrinse 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 warewill not be adequately cleaned. In somecases, this can be corrected by simplyselecting a longer cycle time (using theCycle Select II, Extended 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.

3.11 Final Assembly

1. Check and tighten all electrical terminalscrews.

2. Replace all panels onto the dishwasher.

3. Switch the circuit breaker/fuseddisconnect to the ON position. Be sure toprime the detergent pumps and check forcorrect chemical concentration beforeoperating the unit.

If desired, you can watch the WASH TANKTEMPERATURE and FINAL RINSE TEM-PERATURE displays as they rise. This givesan indication of the amount of time left beforethe dishwasher can be operated.

(constant)

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, you canuse cutlery holders. When loading them:

• Do not overload the holders.

• Always load knives, forks andspoons with the handleDOWN.

• Do not load identical ware intoany given holder. Instead, loadan assortment of knives, forksand spoons into each holder.Identical ware is often tooclosely spaced for effectivecleaning.

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.

When the tank is full and the water hasbeen heated to the correcttemperature, the light above theselected POWER/CYCLE SELECTkey will stop flashing. The machine isnow ready for operation.

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

Position bowls toallow water to drain

OPTIONAL

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 dishwasherstops operating, OR

• Press the STOP/OFF (O) key to stop thewash/rinse cycle before opening the door.

If desired, the cycle can be stopped at any timeby pressing the STOP/OFF (O) key OR byopening the door.


4.4 Operation

Press the START/DRAIN key tobegin the selected cycle. The keywill not work unless the lightabove the selected POWER/CYCLE SELECT key hasstopped flashing.

The dishwasher will begin a wash and rinsecycle. The Soft Start feature pumps the waterthrough the arms slowly for the first few secondsof the cycle to protect fragile ware. After a fewseconds, full pressure will engage.

The time of the total cycle will be at least aslong as the times shown on the machine’s serialplate. When using a cold water supply, themachine will automatically extend the washcycle if necessary until the final rinse water canbe heated to the correct temperature.

OPTIONAL

When the cycle has completed, the dishwasherwill stop operating and sound a three-stagebeeping tone. After the tone has sounded, youmay open the door and unload the dishware.Note that steam escapes when the door isopened; this is normal.

WARNING!Use caution when handling hot dishes,glassware and other items.

4.6 Shutdown

At the end of the shift, press theSTOP/OFF key.

4.5 Between Cycles

Between cycles, leave the door of themachine closed. If the door is left open, thewash tank water will cool. This will activatethe tank heaters, consuming extra energy, andmay lengthen the recovery time when anothercycle is started.

If necessary, you can choose a different cyclelength between cycles by pressing any of thePOWER/CYCLE SELECT keys.

When you are ready to start a new cycle, referto Section 4.3, “Loading.”

Press the START/DRAIN key toempty the tank.

After the water has drained, the dishwasher willenter a self-cleaning mode. The interior will besprayed with hot, fresh water as the boostertank empties. When this is completed, the drainwill “pulse” several times to empty the waterand the dishwasher will automatically shut off.

WARNING!DO NOT open the door of thedishwasher during the self-cleaningprocess! The process will beinterrupted and hot water may sprayout of the dishwasher.

After the dishwasher has finished its self-cleaning cycle, open the door. Remove anyfood particles, scraps or bones from the scrapscreen. MEIKO recommends that the door ofthe dishwasher be left open overnight to allowit to air thoroughly.

SECTION 5 - CLEANING

5 CLEANING

WARNING!Before ANY cleaning, check that thecircuit breaker/fused disconnect is inthe OFF position and that the unit isswitched off.

IMPORTANTThe headings Daily Cleaning and WeeklyCleaning in this section are generalrecommendations based on typical soiling.

If soil beings to accumulate, the unit shouldbe cleaned more frequently. Extensive foodsoil deposits inside the machine work againstoptimal performance. Some items may not becleaned as effectively, resulting in the needfor either a longer cycle or repeat washing. Inaddition, heavy soiling in the wash waterincreases detergent consumption.

5.1Daily Cleaning (or as required)

1. The dishwasher automatically enters aself-cleaning cycle when it is turned off.The interior will be sprayed with hot, freshwater as the booster tank empties.

2. AFTER this cycle ends and the machineshuts down, open the door. Remove anyfood particles, scraps or bones from thescrap screen.

3. Lift out the scrap screen and clean it thor-oughly using a brush and warm water.

4. Lift out the Active Plus filter. Clean it thor-oughly using a brush and warm water. Besure to use care to avoid damaging thescreen on the Active Plus filter.

5. MEIKO recommends that the door of thedishwasher be left open overnight to allow itto air thoroughly.

6. Reassemble all components into the machinebefore operation. Note the following:

- The Active Plus filter MUST be rein-stalled with the slotted end facingDOWN. See Figure 5-1.

- The scrap screen MUST be reinstalledso that the round grate lines up withthe Active Plus filter. See Figure 5-1.

- The top and bottom wash arms areidentical and interchangeable.

- The rinse arms are NOT interchange-able and MUST be replaced in theiroriginal positions. The bottom rinse armis marked “BOTTOM.” The top rinsearm is marked “TOP.”

5.3 Exterior cleaning (as required)

CAUTIONWhen cleaning the exterior of the dishwasher,be sure to follow these guidelines:

• MEIKO strongly recommends usingdetergent when cleaning the exterior of theunit, instead of commercial stainless steelcleaners. These cleaners can damage thesurface of the control panel.

• Never use abrasive cleaners or pads whencleaning the exterior of the dishwasher.These can scratch the surface of the unit.

WARNING!Ensure that detergents and stainlesssteel cleaners are kept out of the inte-rior of the dishwasher. If the interior ofthe unit requires cleaning, refer to thedeliming procedures (Section 5.4).

5.4 Deliming (as required)

Lime scale deposits will occur over time on theinterior of the dishwasher if it is operated usinga hard water supply. MEIKO recommends ahardness of 4-6 grains per U.S. gallon.

A deliming or de-scaling process can be usedto remove these deposits, as well as anyaccumulated food residue.

SECTION 5 - CLEANING

CAUTIONWhen deliming the interior, be sure to followthese guidelines:

• Use deliming agents designed for use withcommercial dishwashers.

• Follow the instructions for the delimingagent that is used.

After the deliming process:

1. Run the dishwasher through 3-6 regularcycles without a load to rinse and sanitizethe interior thoroughly.

2. Inspect the interior for any remainingdeliming agent residue. If residue ispresent, remove it using a soft cloth and hotwater; then, run the machine through onefinal empty cycle.

3. Press the STOP/OFF (O) key; then, pressthe START/DRAIN key. This will empty thetank, ensuring that any deliming agent stillin the tank will be flushed out of the machine.
