II. INSTALLATION AND OPERATING INSTRUCTIONS
1. CHECKS BEFORE INSTALLATION
* Visually inspect the exterior of the shipping container, and any severe damage noted
should be reported to the carrier.
WARNING
Remove shipping carton, evaporator spacer, tape(s) and packing. If packing
material is left in the showcase, it will not work properly.
IMPORTANT
Remove shipping tape holding the door.
* Remove the package containing accessories.
* See the nameplate on the rear of the showcase, and check that your voltage supplied

2. LOCATION
WARNING
This showcase is not intended for outdoor use. Normal operating ambient
temperature should be within 50°F (10°C) to 80°F (27°C). Operation of the
showcase, for extended periods, outside of this normal temperature range
may affect cooling performance.
For best operating results:
* The showcase should not be located next to ovens, grills or other high heat producing
equipment.

for the equipment where its entire bottom
surface can be steadily positioned. Level
the showcase from side to side and front to
rear. Installation of the showcase only partly
in contact with the foundation may result in
deformation, damage or failure. Fig. 2

warp and cause some space between
its center and the showcase bottom. In
this case, provide a support to keep the
foundation level.
* Avoid a site where dripping is not allowed.
* Do not expose the showcase to direct sunlight or higher temperatures to prevent
damage to the plastic housing. Adding additional heat will also affect showcase operating
temperatures. Assure that there is no heat producing equipment located near the case,
no heating vents blowing on the case, or high wattage lamps shining on the case.
* Allow at least 6” (15cm) clearance between the condenser air inlet/outlet and the wall or
other equipment for proper air circulation. The rear of the showcase should have enough
space for smooth operation of the power switch and for easy access to the louver and air

3. SET UP
IMPORTANT
Carry the showcase by holding its bottom.
1) Unpack the showcase, and remove all shipping carton, evaporator spacer, tapes and
packing BEFORE operating the unit. Be careful not to damage the exterior panels when
handling the showcase.

2) Position the showcase in a selected site. Clean the interior with soap and water and
rinse thoroughly.
3) Level the showcase in both the left-to-right and the front-to-rear directions.
4) The perimeter where the machine touches the counter should be sealed with silicone.
4. ELECTRICAL CONNECTIONS
* This showcase must be plugged into the separated power receptacle which has enough
capacity. The maximum allowable voltage variation should not exceed ± 10 percent of the
nameplate rating. See the nameplate.
5. DRAIN CONNECTIONS
* The hose may be connected to either right or left joint, whichever is convenient.
* Keep more than 2 vertical inch (5 vertical cm) air gap between the drain pipe end and the
sink.

6. FINAL CHECK LIST
1) Is the showcase level?
2) Is the showcase in a site where the ambient temperature is within 50°F (10°C) to 80°F (27
°C) all year around?
3) Have all shipping carton, evaporator spacer, tape(s) and packing been removed from
the showcase?
4) Have all electrical and piping connections been made?
5) Has the power supply voltage been tested or checked against the nameplate rating?
6) Has the user been given the instruction manual and instructed on how to operate the
showcase and the importance of periodic maintenance recommended?
7) Has the user been given the name and telephone number of the authorized service
agency?

7. START UP
IMPORTANT
1. Be careful not to let water into the machine compartment and over the
exterior. This might cause an electric shock hazard.
2. Do not plug in and unplug the showcase frequently. This may result in
failure or shorter service life.
3. The showcase is intended to display sushi materials and keep them cool
during business hours. The showcase contains a large amount of glass
and provides less refrigeration and cold storage capacity than ordinary
refrigerators. Before displaying sushi materials, allow the showcase to
operate for about 1 hour to cool down. Fully refrigerate sushi materials in a
refrigerator prior to displaying them in the showcase.
4. During operation, moisture inside the showcase causes frost to build up on
the evaporator pipe inside. Frost has an insulating effect on the evaporator
pipe and reduces refrigeration performance. Every time the door is
opened, warm and humid air comes in and raises the interior temperature
to accelerate frost formation. Opening of the doors should be kept to a
minimum to maintain proper operating temperatures. Do not leave the
doors open continuously.
Since frost on the evaporator pipe reduces refrigeration performance, the
showcase cannot be used continuously. After business hours, return sushi
materials to a refrigerator and turn off the showcase.
Leave the showcase off for at least 1 to 2 hours to defrost. Failure to
defrost the showcase will result in improper operating temperatures.
In some conditions, frost may build up in a short time and reduce cooling
performance. In these conditions, defrost the showcase as needed
during the day. While defrosting the showcase, move sushi materials to a
refrigerator to prevent deterioration.
5. It is normal to find condensation on the showcase in a humid or rainy
weather. Simply wipe it off with a soft cloth from time to time.
6. Control the food temperature by placing the food mounts as follows:
Normal condition
When food temp. is too low For more intensive cooling

7
7. The maximum safe height for displaying food products is 3.5” (9cm) above
the interior bottom. Food products should not be placed above this height
as they may not remain cold enough to avoid spoilage.
8. If the showcase is turned off, wait for at least 3 minutes before restarting
the showcase. Otherwise the overload protector may operate and allow
defrost water to drip onto the items inside. The overload protector will reset
automatically in 30 minutes.
9. To prevent damage to the glass parts, do not
place or hit any tableware, bottles or edged
tools directly on the glass surfaces. Even a

plug(s) provided.
1) Clean inside the showcase.
2) Plug in the showcase, and turn on the power switch.
* When not in use, dry the showcase thoroughly and store it in a dry place.

III. MAINTENANCE AND CLEANING INSTRUCTIONS
IMPORTANT
1. Before carrying out any cleaning or maintenance operations, unplug the
showcase.
2. Do not disassemble the showcase further than illustrated in Fig. 1.
3. Do not touch or wet the machine compartment parts. This could result in
failure or breakdown.
1. INTERIOR/EXTERIOR
* Clean the interior and food mounts every day for sanitary use.
* Use a soft cloth soaked in warm water to clean off the exterior. Do not use a water jet to
clean the exterior.
* Use only a neutral cleaner. Other chemical agents might cause damage to the interior
and exterior surfaces.
Note: To prevent damage to the part surfaces and the plating on the evaporator, do not
use a scourer on the interior/exterior surfaces.
2. DRAIN PIPE CLEANING

Check the condenser once a year, and clean if required by using a brush or vacuum
cleaner. More frequent cleaning may be required depending on the location of the
showcase.
5. CHECKING GROUND FAULT INTERRUPTER
Push the test button at least once a month, and simulate a ground fault on the load circuit.
