Glass touchscreen display - Provides a range of

informationin plaintext,including washandrinse tank

temperatures, selection of different cycle times, a

graphical progress bar, operating state, and service

information.

M-iClean Filter - During operation, food soil is

continually strained from the wash water by the two-

stageM-iClean Filter. Soilis automaticallydrained out

ofthe machineat theendof eachcycle.This improves

washingresults,andminimizes bothdetergentuse and

manualcleaning.

Color coded components - Componentsthat require

manualcleaningare coloredblue for intuitiveoperation

andeasier stafftraining.

AutoSafe - Theinternalbooster heater isautomatically

regulated to ensure proper sanitizing temperatures,

regardlessof theincomingwater temperature.

Soft Start - The wash water is pumped at a reduced

pressure for the first few seconds of the wash cycle,

protectingthe warefrombeingmovedbyasuddenburst

ofpressure.

Pumped Final Rinse - Aninternalrinse pump ensures

that the final rinse pressure is constant, for efficient

operation and consistent results.

Pumped Drain - Accommodates wall or floor drains.

Leak Detection System - Stops machine operation if

an internal leak is detected.

SECTION 3 - INSTALLATION

3.3 Uncrating, Positioning and Leveling

CAUTION

Somewater mayremainin thelines after pre-shipping

testing.Duringshippingandinstallation,thedishwasher

should ONLY be positioned upright.

1. Removeall shippingandpackaging materialfrom

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. Checkforshippingdamageasdescribed in Section

2,“Transport andShipping.”If damageis present,

call MEIKO Customer Service at

1-800-868-3840, providing full details on the

customer, serial number and extent of damage

present. MEIKO will file a freight claim based on

thisinformation.

3. Move the appliance to the installation area and

SECTION 3 - INSTALLATION

3.5 Priming the Detergent and Rinse Aid Lines

After the machine has been connected to appropriate

detergent and rinse aid containers, the supply lines

must be primed to remove air from the lines. To prime

thelines, usethe following procedure.

3.6 Checkingfor Correct Chemical Concentration

The normal settings for chemical injection are:

• Detergent- 0.192 oz.per gallonof washwater (1.5

ml per liter).

• Rinseaid -0.038 oz.per gallon ofrinse water(0.3

ml per liter).

To check if the normal settings are correct for your

chemicals,RUNTHREEEMPTYLOADSto completely

cyclethe water supplyand obtainaccurate testresults.

This will only take a few minutes. Then, run a sample

load with soiled ware and examine the results.

• If the detergent setting is too low, the ware will not

be adequately cleaned. In some cases, this can

be corrected by simply selecting a longer cycle

time (using the Cycle Select II, Extended or Cycle

Select III, Heavy buttons), but the detergent

concentration may also need to be adjusted.

• If the rinse aid setting is too low, spotting or

streaking may occur on the ware.

• If too much of either chemical is added, the extra

chemicals will be wasted. This is often difficult to

detect except by determining how long your

chemical supplies last. If the chemicals are being

exhausted quickly, you may need to have the

chemicalconcentration adjusted.

IN ALL CASES, ANY ADJUSTMENTS OF THE

FACTORYCHEMICAL INJECTION SETTINGSARE

4.3 Loading Guidelines

The loading guidelines shown here will lead to faster,

moreefficient cleaningof yourware.

Load hollow or concave

dishware (glasses, large

bowls,etc.)upside-down.

Thisallowswater todrain

more quickly, preventing

stains.

Forbest results, glasses,

mugsandcupsshouldbe

loaded into compart-

menteddishracks.

For greater efficiency in

loading cutlery, you can

use cutlery holders.

Whenloading them:

• Do not overload the

holders.

• Always load knives,

forksandspoonswith

thehandle DOWN.

Load plates, flat trays,

etc. at an angle with the

inside face pointing up.

Ensurethat water cannot

pool in hollow spaces in

theware(trayedges,etc.)

Do not stack items in the

dishwasher, or overload

the dishracks. This

prevents the wash water

from reaching the food

residue.Itismoreefficient

to load the dishwasher

with fewer items and run

multiple, shorter cycle

times.

• Do not load identical ware into any given holder.

Instead, load an assortment of knives, forks and

spoonsinto each holder. Identicalware isoftentoo

closelyspaced foreffective cleaning.

breaker/fuseddisconnectisintheOFFposition

and that the unit is switched off.

IMPORTANT

TheheadingDailyCleaningisageneralrecommendation

based on typical soiling. If soil beings to accumulate,

theunit shouldbe cleanedmore frequently. Extensive

food soil deposits inside the machine work against

optimalperformance. Someitems maynot be cleaned

as effectively, resulting in the need for either a longer

cycle or repeat washing. In addition, heavy soiling in

thewash waterincreases detergentconsumption.

5.1 Daily Cleaning (or as required)

1. The dishwasher automatically enters a shutdown

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. Remove any food particles,

scraps or bones from the scrap screen.

3. Removethe upperand lowerwasharms. Turnthe

retaining screw counter-clockwise until it is loose,

then lift out the arm. See Figure 5-1.

4. Lift out the scrap screen assembly out of the

machine.See Figure5-2.

5. Removetheblue M-iClean Filterfromthebottom of

the scrap screen. See Figure 5-3.

6. Inspect the pump filter at the bottom of the tank. If

it is soiled, remove it by depressing the gray latch

asshown inFigure 5-4.

7. Cleanthewasharms,scrapscreen,M-iCleanFilter,

and(if necessary)the pumpfilter at thesink using
