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.

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

• Connecting the fresh water 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:

• INST ALLATION 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 water . If this is not
possible, these items should be
protected from the small quantities of
water that are splashed 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
line (supplied by the customer) must
be present.

- Appropriate detergent, rinse aid and
sanitizer containers should be installed
and ready for connection to the
appliance.

• GENERAL REQUIREMENTS
Authorized personnel should be available

to perform the actual utility connections.

• Connecting the accumulator drain.

• Connecting the machine to tabling.

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

3.6 Dispensing system overview

The CS 70 is equipped with liquid detergent,
rinse aid and sanitizer pumps. Each pump is
equipped with a supply tube that exits the rear
of the machine. A stiffener tube is also
provided for the ends of each tube. The end
of the tube with the stiffener should be
inserted and fastened into appropriate liquid
chemical containers (supplied by others).

During operation, chemicals are automatically
dispensed according to the timed settings for
each pump, which can be individually
configured as required. A proof of delivery
window provides a visual indication that
chemicals are being dispensed.

See Figure 3-5.

3.7 Connecting Chemical Containers

1. Check that all chemicals are compatible
with the unit. In particular, a commercial
(not a domestic) detergent MUST be used.

2 Check that the containers are correctly

installed or positioned according to the
manufacturer’s instructions.

3. Each chemical dispensing pump is
equipped with a supply tube that exits the
rear of the machine. A stiffener tube is also
provided for the end of each tube.

4. Assemble a stiffener tube onto the end of
each of the chemical tubes using two tie
wraps. See Figure 3-6.

3.8 Fresh Water Supply Connection

CAUTION

Before connecting the water supply, the line
MUST be flushed clean of all debris, including
(but not limited to) pipe sealant, metal
particles, solder, etc. This debris can damage
the appliance.

IMPORTANT

In some cases, local codes dictate that water
supply connections be made only by a
certified professional.

1. Check that iron or other metal particles
cannot contaminate the fresh water
supplied to the dishwasher.

2. Check that the incoming water pressure
is within the acceptable range for the
appliance (maximum 100 psi, 6.89 bars).

3. Check the incoming water temperature.
MEIKO recommends a water temperature
of 140°F/60°C for optimum operation.

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

5. Because the water inlet incorporates a “Y”
strainer, an additional “Y” strainer in the
water supply is unnecessary unless
required by local, national or international
codes.

6. Connect the customer-supplied water line
to the street elbow fitting on the fill
assembly . Use a sealing compound on the
threads to ensure that no leaks are present
in the connection. See Figure 3-7.

SECTION 3 - INSTALLATION

3.13 Checking for Correct Chemical

Concentration

The normal factory settings 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).

• Sanitizer - titrated using sodium

hypochlorite (NaClO) to 50 ppm minimum.
Other chemical sanitizing solutions
(iodine, etc.) may be used if permitted by
local, national and international codes.

• These settings are factory defaults, but all

settings used should always be checked
to ensure proper operation.

T o check if the normal settings are correct for
your chemicals, RUN THREE EMPTY
LOADS to completely cycle the water supply
and obtain accurate test results. This will only
take a few minutes. Then, run a sample load
with soiled ware and examine the results.

IMPORTANT

In all cases, any adjustments of the chemical
injection settings are to be performed either
by a chemical leasing company professional,
or by a MEIKO authorized service agent.
Changes by unauthorized personnel may void
your warranty.

If you need to contact your Authorized Service
Agency, please contact MEIKO Technical
Support at 1-800-868-3840.

• If the detergent setting is too low , the ware

will not be adequately cleaned.

• If the rinse aid setting is too low, spotting

or streaking may occur on the ware.

• The sanitizer setting should be confirmed

by the chemical leasing company
professional using an approved method
(typically test strips are used).

• If too much detergent or rinse aid 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 chemical concentration adjusted.

• If it is necessary to adjust any of the

chemical injection settings, refer to
Section 4, Programming for instructions.

Page 13
