SECTION 1 - INTRODUCTION
1
INTRODUCTION
1.1 Overview of Equipment
The Meiko Model FV 40.2 is a commercial
dishwasher designed for cleaning dishes,
glassware, 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
controlled by the electronic control system to
ensure proper wash and rinse temperatures,
regardless of the incoming water supply.
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.
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.

INSTALLATION
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.
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
CAUTION
During shipping and installation, the dishwasher
may ONLY be positioned upright or on its left side.
Some water may remain in the lines after preshipping testing. If the unit is positioned in any
manner EXCEPT upright or on its left side, this water
can affect the operation of the water level sensor.
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

SECTION 3 - INSTALLATION
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 3-3). Thread the incoming
supply leads through the strain relief and
to the main electrical supply terminal block.
4. Refer to Figure 3-4 and to 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.
tubes to be routed to external pumps, if they
are used.
CAUTION
If the unit will NOT use one or both of the
chemical supply tubes, cut the unused tube(s)
close to the point where it exits the machine’s
exterior panel and seal it using the supplied
plug and wire clamp. See Figure 3-5.
3.6 Dispensing system overview
The FV 40.2 is designed for use with liquid
detergent and liquid rinse additive. The unit
is not compatible with solid detergents
and/or rinse additives.
The tubes located at the lower rear of the
warewasher are pre-plumbed to supply liquid
detergent (clear tube) and liquid rinse additive
(blue tube). See Figure 3-3.
Some units are equipped with optional internal
liquid detergent and rinse additive dispensing
pumps, in which case containers can simply
be attached to the supply tubes. Units without
the optional internal pumps will require the
Fresh water
connection

3.7 Installing External Chemical Pumps (if so equipped)
IMPORTANT
Some local codes dictate that electrical
connections be made only by a certified
professional.
The machine’s dispensing terminal block
includes relays that close during specific times
in the cycle. The closed relays complete a
circuit, creating a “window” that allows
activation of external chemical dispensers.
• The rinse additive relay is closed for 16.5
seconds when the booster tank begins its
fill cycle. A timer in the external system
should be used to regulate the amount of
rinse additive injected per cycle.
• The detergent relay is closed whenever
the wash pump is in operation.
IMPORTANT
It is HIGHLY RECOMMENDED to use a
timer system to control detergent injection,
NOT a detergent concentration probe.
Two pre-plumbed 1/4” ID tubes serve as the
connection points for the chemical supplies.
The CLEAR tube supplies detergent, and the
BLUE tube supplies rinse additive.
To install external chemical dispensers:
1. Check that the pump(s) are correctly
installed according to the manufacturer’s
instructions.
2. Locate the chemical dispenser terminal
block. See Figure 3-3.
3. Thread the incoming leads from the
chemical pumps through the strain reliefs
(at the lower rear of the machine) and to
the chemical dispenser terminal block.
4. Connect the wires as shown in Figure
3-6. Note that the terminal block supplies
LINE VOLTAGE SIGNALS. An additional
transformer may be required depending
on the supply requirements of the external
pumps.
5. Adjust the strain reliefs to fasten the wiring
in place. Leave enough slack in the wiring
to prevent stress on the terminal
connections. Bundle the wires together
using wire ties to prevent them from
tangling when repositioning the appliance.

3.8 Connecting Chemical Containers or Dispensers (if so equipped)
This section applies to units with either internal or external chemical dispensing pumps.
1. Check that the rinse additive and
detergent are compatible with the unit. In
particular, a commercial (not a domestic)
LIQUID detergent MUST be used. The
Model FV40.2 is not compatible with solid
detergents and/or rinse additives.
2. Check that the containers/dispensers are
correctly installed according to the
manufacturer’s instructions.
3. If the dishwasher is equipped with factory
internal chemical dispensing pumps, two
strainer assemblies for the chemical
containers are also included. See Figure
3-7. These strainers should be assembled
onto the lids for the detergent and rinse
additive containers.
4. Locate the CLEAR liquid detergent supply
tube at the lower rear of the unit. Connect
the tubing to the detergent container.
5. Locate the BLUE liquid rinse additive
supply tube at the lower rear of the unit.
Connect the tubing to the rinse additive
container.
6. If using the strainers shown in Figure 3-7,
be sure to use the supplied wire clamps
to fasten the chemical supply tubes
securely. Meiko STRONGLY RECOMMENDS the use of a sealing compound
on these connections to prevent leakage.

SECTION 3 - INSTALLATION
3.9 Fresh Water Supply Connection
CAUTION
Before connecting the water supply hose, 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 (8.7-72.5 psi, 0.6-5.0 bars). It
may be necessary to increase the pressure (with a booster pump) or to reduce
the pressure (with a reducing valve).
3. Check the incoming water temperature.
Meiko recommends a water temperature
of 140°F/60°C for optimum operation,
although if necessary the appliance will
operate correctly using water at any
temperature of 140°F/60°C or lower.
Colder water will result in a longer preheat
time (during initial startup) and may extend
the cycle time to allow the final rinse water
to heat to 180°F/82°C.
4. Check the incoming water hardness.
Meiko recommends a hardness of 4 grains
per U.S. gallon (7 DH German hardness).
5. Because the water inlet incorporates a
stainless steel dirt trap, an additional trap
is unnecessary unless required by local,
national or international codes.
6. The dishwasher includes a water supply
line that ends in an enclosure containing
the water inlet valve and the Aqua-Stop
shutoff valve (see Figure 3-8). Connect the
customer-supplied water line to the fitting
on the end of this enclosure. Use a sealing
compound on the threads to ensure that no
leaks are present in the connection.
7. Check that the water line is long enough
to permit the unit to be repositioned for
servicing.

vertical rise limitations
3.10 Drain Hose Positioning
1. Check that the end of the drain hose will
empty into a drain with a minimum
diameter of 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.
CAUTION
No portion of a wall drain system may be
higher than 24” (610m) A.F.F. to ensure
that the drain pump is operating within
rated specifications. See Figure 3-9.
3. Route the drain hose to the drain. In some
cases, a grease trap (supplied by others)
must be fitted into the waste water line. If
this trap is required for your installation,
check that it is present.

3.13 Checking for Correct Chemical
Concentration
Machines equipped with external chemical
dispensing systems will have normal settings
recommended by the manufacturer.
For machines equipped with factory internal
chemical dispensing systems, the normal
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).
To 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.
• 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, Medium or Cycle Select
III, Heavy buttons), but the detergent
concentration may also need to be adjusted.
• If the rinse additive 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 chemical concentration adjusted.
IN ALL CASES, ANY ADJUSTMENTS OF
THE FACTORY CHEMICAL INJECTION
SETTINGS ARE TO BE PERFORMED
ONLY BY A MEIKO AUTHORIZED
SERVICE AGENT. CHANGES BY
UNAUTHORIZED PERSONNEL WILL
VOID YOUR WARRANTY.
If you need to contact your Authorized
Service Agency, please contact Meiko

begin to flash, showing that the tank
is filling and the water is heating to
the correct temperature.
The time required for filling and preheating
will vary based on the temperature of the
incoming water supply. For incoming water
at 140°F/60°C, the machine may need up to
15 minutes to fill and heat to the correct wash
temperature. The default wash temperature
is several degrees above 150°F/66°C for
efficient operation.

Load hollow or concave dishware (glasses,
large bowls, etc.) upside-down and at an
angle. This allows water to drain more quickly,
preventing stains.
For greater efficiency in loading cutlery, you
can use cutlery holders. When loading them:
• Do not overload the holders.
• Always load knives, forks and
spoons with the handle
DOWN.
• Do not load identical ware
into any given holder. Instead,
load an assortment of knives,
forks and spoons into each
holder. Identical ware is often
too closely spaced for
effective cleaning.
Do not stack items in the dishwasher. Stacked
items require longer or multiple cleaning
cycles because the wash water cannot reach
the food residue as effectively. It is more
efficient to load the dishwasher with fewer
items and run multiple, shorter cycle times.
SECTION 4 - OPERATION
4.4 Operation
Press the CYCLE/DRAIN key
to begin the selected cycle.
The key will not work unless
the light above the selected
POWER/CYCLE SELECT
key has stopped flashing.
The dishwasher will begin a wash and rinse
cycle. The Soft Start feature pumps the water
through the arms slowly for the first few
seconds of the cycle to protect fragile ware.
After a few seconds, full pressure will engage.
The time of the total cycle will be at least as
long as the times shown in Section 4.1. When
using a cold water supply, the machine will
automatically extend the wash cycle if
necessary until the final rinse water can be
heated to the correct temperature.
OPTIONAL
If desired, the cycle can be stopped at any
time by pressing the POWER OFF (
)
button OR by opening the door.
WARNING!
If the door is opened suddenly, hot
water can spray out of the dishwasher. To
prevent this from happening:
• Open the door slowly until the dishwasher
stops operating, OR
key to stop the wash/rinse
• Press the
cycle before opening the door.
When the cycle has completed, the
dishwasher will stop operating and sound a
three-stage beeping tone. After the tone has
sounded, you may open the door and unload
the dishware. Note that steam escapes when
the door is opened; this is normal.
WARNING!
Use caution when handling hot
dishware.
4.5 Between Cycles
Between cycles, leave the door of the
machine closed. If the door is left open, the
wash tank water will cool. This will activate
the tank heaters, consuming extra energy, and
may lengthen the recovery time when another
cycle is started.
If necessary, you can choose a different cycle
length between cycles by pressing any of the
POWER/CYCLE SELECT keys.
When you are ready to start a new cycle, refer
to Section 4.3, “Loading.”
4.6 Shutdown

to empty the tank.
After the water has drained, the dishwasher
will enter a self-cleaning mode. The interior
will be sprayed with hot, fresh water as the
booster tank empties. When this is completed,
the drain will “pulse” several times to empty
the water and the dishwasher will
automatically shut off.
WARNING!
DO NOT open the door of the
dishwasher during the self-cleaning process!
The process will be interrupted and hot water
may spray out of the dishwasher.
After the dishwasher has finished its selfcleaning cycle, open the door. Remove any
food particles, scraps or bones from the scrap
screen. Meiko recommends that the door of
the dishwasher be left open overnight to allow
it to air thoroughly.

CLEANING
WARNING!
Before ANY cleaning, check that the
circuit breaker/fused disconnect is in
the OFF position and that the unit is
switched off.
IMPORTANT
The headings Daily Cleaning and Weekly
Cleaning in this section are general
recommendations based on typical soiling.
If soil beings to accumulate, the unit should
be cleaned more frequently. Extensive food
soil deposits inside the machine work against
optimal performance. Some items may not be
cleaned as effectively, resulting in the need
for either a longer cycle or repeat washing. In
addition, heavy soiling in the wash water
increases detergent consumption.
5.1 Daily Cleaning (or as required)
1. The dishwasher automatically enters a
self-cleaning 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. Lift out the scrap screen and clean it thoroughly using a brush and warm water.
4. Lift out the Active Plus filter. Clean it thoroughly using a brush and warm water. Be
sure to use care to avoid damaging the
screen on the Active Plus filter.
5. Meiko recommends that the door of the
dishwasher be left open overnight to allow
it to air thoroughly.
6. Reassemble all components into the machine before operation. Note the following:
-
-
The Active Plus filter MUST be reinstalled with the slotted end facing
DOWN. See Figure 5-1.
The scrap screen MUST be reinstalled
so that the round grate lines up with
the Active Plus filter. See Figure 5-1.

following steps:
1. Open the door. Remove and clean the
scrap screen and Active Plus filter as described in Section 5.1, “Daily Cleaning.”
2. Remove and disassemble the arms as
shown in Figures 5-2 and 5-3. Clean the
arms with a brush and warm running water.
3. Reassemble all components into the dishwasher. Note the following:
- The Active Plus filter MUST be reinstalled with the slotted end facing
DOWN. See Figure 5-1.

5.3 Exterior cleaning (as required)
CAUTION
When cleaning the exterior of the dishwasher,
be sure to follow these guidelines:
• Meiko strongly recommends using
detergent when cleaning the exterior of the
unit, instead of commercial stainless steel
cleaners. These cleaners can damage the
surface of the control panel.
• Never use abrasive cleaners or pads when
cleaning the exterior of the dishwasher.
These can scratch the surface of the unit.
WARNING!
Ensure that detergents and stainless
steel cleaners are kept out of the interior of the dishwasher. If the interior of
the unit requires cleaning, refer to the
deliming procedures (Section 5.4).
5.4 Deliming (as required)
Lime scale deposits will occur over time on
the interior of the dishwasher if it is operated
using a hard water supply. Meiko recommends
a hardness of 4 grains per U.S. gallon (7 DH
German hardness).
A deliming or de-scaling process can be used
to remove these deposits, as well as any
accumulated food residue.
Bearing
ring
CAUTION
When deliming the interior, be sure to follow
these guidelines:
• Use deliming agents designed for use with
commercial dishwashers.
• Follow the instructions for the deliming
agent that is used.
After the deliming process:
1. Run the dishwasher through 3-6 regular
cycles without a load to rinse and sanitize
the interior thoroughly.
2. Inspect the interior for any remaining
deliming agent residue. If residue is
present, remove it using a soft cloth and
hot water; then, run the machine through
one final empty cycle.
3. Press the POWER OFF ( ) button; then,
press the CYCLE/DRAIN ( ) button.
This will empty the tank, ensuring that any
deliming agent still in the tank will be
flushed out of the machine.
WARNING!
Ensure that ALL residue of the deliming
agent is removed. Residue from the
agent can:
- Pose a health hazard;
- Damage seals and plastic components inside the dishwasher.
