SECTION 1 - INTRODUCTION

1INTRODUCTION

1.1 Overview of Equipment

The MEIKO M-iClean is a commercial dishwasher
designed for cleaning dishes, glassware, cutlery and
kitchen utensils with a minimum of employee
intervention or supervision.

Features of the dishwasher include:
Illuminated door handle - Visible from across the

room, the color of the handle provides visual cues to
the operator about the machine operating state (ready
for operation, washing, important messages).

Glass touchscreen display - Provides a range of
information in plain text, including wash and rinse 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 two­stage M-iClean Filter. Soil is automatically drained out
of the machine at the end of each cycle. This improves
washing results, and minimizes both detergent use and
manual cleaning.

Color coded components - Components that require
manual cleaning are colored blue for intuitive operation
and easier staff training.

Auto Safe - The internal booster heater is automatically
regulated to ensure proper sanitizing temperatures,
regardless of the incoming water temperature.

Soft Start - The wash water is pumped at a reduced
pressure for the first few seconds of the wash cycle,
protecting the ware from being moved by a sudden burst
of pressure.

Pumped Final Rinse - An internal rinse pump ensures
that the final rinse pressure is constant, for efficient
operation and consistent results.

SECTION 3 - INSTALLATION

3INST ALLATION

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.

IMPORTANT

It is the responsibility of the owner to ensure that all
aspects of the installation comply with all applicable
local and national codes.

IMPORTANT

The appliance’s warranty is not valid until a MEIKO
Authorized Service Agent performs a Startup and
Demonstration on the appliance. This Demonstration
should be scheduled after installation.

Installation of the dishwasher involves the following
steps:

• Verifying that the utility connections are present,
are appropriate for the appliance, and comply with
all applicable local and national codes.

• Unwrapping the appliance (leaving the shipping skid
in place for easier movement) and checking for
shipping damage.

• Moving the appliance to the installation location,
removing the skid, and leveling the feet.

• Connecting the electrical supply .

3.2 Requirements Before Installation

Before the installer can uncrate and move the appliance
to the installation location, the following conditions
MUST be met:

• INSTALLA TION AREA REQUIREMENTS

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

- The area MUST have a firm floor surface. It is
possible to compensate for uneven flooring by
adjusting the feet.

- The area should be away from appliances,
furniture or surfaces that can be damaged by
steam. If this is not possible, these items
should be protected from the small quantities
of steam that are released during normal
operation of the dishwasher.

• UTILTITY CONNECTION REQUIREMENTS

- Connections must be present and ready for
hookup to the appliance. All utility supplies must
comply with the electrical information labels,
with the information on the data plate, and with
all applicable local and national codes.

- Electrical leads and the water supply hose
(supplied by the customer) must be present.

- Appropriate chemical dispensing containers
should be installed and ready for connection
to the appliance.

• Connecting the fresh water supply .

• Positioning the drain hose.

• Connecting the warewasher’s detergent and rinse
aid tubes to appropriate dispensers.

• Priming the detergent and rinse aid pumps.

• Contacting your MEIKO Authorized Service Agent
to perform a Startup and Demonstration on the
appliance. This step also validates the appliance’s
warranty.

• GENERAL REQUIREMENTS
Authorized personnel should be available to perform

the actual utility connections.

3.3 Uncrating, Positioning and Leveling

SECTION 3 - INSTALLATION

Some water may remain in the lines after pre-shipping
testing. During shipping and installation, the dishwasher
should ONL Y be positioned upright.

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. MEIKO will file a freight claim based on
this information.

3. Move the appliance to the installation area and

the appliance or any of its components.

Figure 3-1: Utility connection locations

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

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

CAUTION

The dishwasher MUST be level for proper operation.

3.4 Accessing the Utility Connections

Utility connections are accessible on the lower rear of
