SECTION 1 - INTRODUCTION

1INTRODUCTION

1.1 Overview of Equipment

The MEIKO Model DV 200.2 is a commercial
dishwasher designed for cleaning dishes,
glassware, trays, cutlery and kitchen utensils
with a minimum of employee intervention or
supervision.

A control keypad allows easy selection of
three different dishwashing cycles to
accommodate different levels of soiling. A
digital display permits easy monitoring of
operation.

Other features of the unit that affect operation
include:

Auto Safe - An internal booster heater is regulated
by the electronic control system to ensure a
proper sanitizing final rinse temperature,
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. This protects the ware from
being moved or damaged by a sudden burst
of pressure.

Pumped Rinse - An internal rinse pump
ensures that the final rinse pressure is
constant.

Pumped Drain - Accommodates wall or floor
drains.

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

Positive-Action Door Handle - After the unit
has been started for the day, the wash cycle
can be activated simply by pressing down on
the door handle.

For efficient and SAFE operation, be sure to
follow the installation and operating
instructions provided in this manual. In
particular, all safety symbols and notices on
the equipment and in the supplied
documentation must be followed.

SECTION 3 - INSTALLATION

3INSTALLATION

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.

• Installing the chemical dispensing system.

For units equipped with the optional
dispensing system, this involves
connecting the warewasher’s detergent and
rinse additive tubes to appropriate dispensers.

For units without the optional system, the
dispensing system installer should follow
the manufacturer’s instructions AND the
instructions in Section 3 of this Manual.

• Connecting the fresh water supply.

• Positioning the drain hose.

• Connecting the machine to tabling.

Page 4

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

3.2 Requirements Before Installation

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

• INSTALLATION 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.

- For units without the optional

dispensing system, external detergent
and rinse additive pumps (if used)
should be installed according to the
manufacturer’s instructions.

- For units with the optional dispensing

system, appropriate dispensers or
containers should be installed and
ready for connection to the appliance.

• GENERAL REQUIREMENTS
Authorized personnel should be available

to perform the actual utility connections.

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

3. Move the appliance to the installation area and
remove the skid. Use caution to avoid damaging
the appliance or any of its components.

4. Using a spirit level, check that the appliance is
level in both directions (front-to-back AND side­to-side). If necessary, level the appliance by
rotating the bottom section of each foot.

3.4 Accessing the Utility Connections

Water supply and drain connections are located
at the lower rear of the dishwasher. The electrical
supply enters through a strain relief at the lower
rear, but the terminal blocks are accessed from
the front of the machine.

To remove the lower front panel:

1. Remove AND RETAIN the two screws on the
bottom edge of the lower front panel. See
Figure 3-1.

2. Slide the panel down and away from the
dishwasher to remove it. As you pull the panel
away from the dishwasher, disconnect the ribbon
cable for the MIKE 2 controller to avoid damage.

3. Remove the screw that holds the electrical box
in place, as shown in Figure 3-2. Swing the box
down as shown in Figure 3-3. The terminal
blocks for the main electrical supply and
chemical dispensers (if used) are behind the
electrical box, on the right side of the machine.

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. Amperage and minimum
supply wire specifications are shown on
the serial plate and on the electrical
information label.

2. Check that the incoming power leads are
long enough to permit the unit to be
repositioned for servicing.

3. Locate the strain relief for the electrical
supply wiring at the lower rear of the
machine (Figure 3-4). Thread the
incoming supply leads through the strain
relief and to the main electrical supply
terminal block at the front of the machine
(Figure 3-5).

4. Refer to Figure 3-6 and the electrical wiring
diagram. Connect the power supply and
ground leads as indicated.

5. Adjust the strain relief to fasten the wiring
in place. You should leave enough slack
in the wiring to prevent stress on the
terminal connections.

3.6 Dispensing system overview

The DV 200.2 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.

• Two dummy plugs covering
holes in the back of the wash
tank that can be used for de­tergent injection. The plugs are
accessed by removable panels
on the sides of the machine.
Either plug can be used.

• A hole in the bottom of the wash
tank for the installation of a de­tergent concentration probe.

A dispensing system terminal block
(shown in Figure 3-7) provides
contacts for two line voltage
relays. These relays, when closed,
provide a “window” for external
pump systems to activate.

• The rinse aid pump relay closes
for approximately 16.5 seconds
whenever the booster tank
refills (once per cycle).

• The detergent pump relay
closes whenever the wash
pump is in operation.

Activation of the pumps can be
controlled as follows:

• Solid detergent systems should
use a detergent concentration
probe installed in the wash tank
to activate the external pump.
A dummy plug at the bottom of
the wash tank provides an
installation location for the probe.
