This service manual does not include comprehensive operating instructions for the user; it is only a further
supplement to the operating instructions.
It intends for a trained service technician. As a result, many important safety instructions for the user are
missing about the scope and readability. In case of doubt, please observe the information in the operating
instructions for transport, installation, operation, and electrical safety and never pass on this service manual in
place of the operating instructions.
This cabinet is intended for the storage of packaged foods at a constant temperature. This cabinet mustn’t
be used to cool down or freeze foods.
Area of application:
Climate Class
Ambient Temperatures andHumidity
4
+30°C with %55 RH
5
+40°C with %40 RH
The cabinet must be installed in a dry, well-ventilated room away from direct sunlight at a sufficient
distance from radiators and other sources of heat. Please always consider the waste heat of all cabinets
installed in one room!
The ambient temperature must lie between a minimum of +16 °C and a maximum of + 40°C. A gap of at
least 50 cm must be kept between the top edge of the machine compartment and the ceiling. The air
exchange in this area must not be obstructed from the front or the side by screens etc. hanging from the
ceiling.
For electrical safety reasons, the cabinet must not be operated outside. The refrigeration technology of the
cabinet does not function outside or in unheated rooms (particularly in colder seasons) and can be damaged
by low temperatures.

Distance from walls and ceiling:
A gap of at least 500 mm must be kept between the top edge of the machine compartment and the
ceiling, and of at least 50 mm from walls, furniture and other cabinets.

Depending on the temperature and air humidity at the installation site as well as the selected setpoint
setting, the moisture in the ambient air can condense on the surface of a refrigerating unit due to itsdesign.
If several cooling or refrigeration units are set up side by side, this condensation effect becomesstronger,
and a lower air quantity can circulate between the cabinets. As a result, a minimum distance of 30 to 50mm
must be kept between the cabinets depending on the temperature and airhumidity.
These gaps must not be sealed either at the top or bottom, but can be covered by a stainless-steelpanel
from the front for aesthetic purposes. The panel must be removable for cleaning within thegaps.
If it is not possible for air to circulate freely at the bottom, e.g. due to a base installation, then thegaps
cannot be sealed at the front.
4) Setting up Several Cabinets Side by Side

Warning The refrigeration unit is located at the top of the cabinet. At least two people
are required to lay down the cabinet and set it up right again.
Important If the cabinet has laid on its back or was transported horizontally, then it must
stand upright for at least two hours before switching it on to allow the oil to collect
inthe compressor.
Once the cabinet is on its back, the transport pallet must be removed by the following order;
1-2-3) 2 pieces of long wooden pieces at the bottom of the pallet are detached from the lower part of the pallet
with the help of a screwdriver from the left side of the refrigerator.
4-5-6) The other side of the long wooden pieces is moved to the right side of the refrigerator and detached from
the bottom of the pallet with the help of a screwdriver.
5) Unpacking and Installing the Cabinet

7
HOSHIZAKI EUROPE
B.V.
7-8- 9)
Then, 2 pieces of short wooden pieces at the back of the pallet are removed by hand. Once the pieces of wood that hold the
cabinet to the pallet are removed, it means the cabinet is no longer connected to the pallet.
10-11-12) With the help of a pallet truck or by means of 2 people, the cabinet is first tilted to one side from the pallet and
then the pallet is removed from the bottom.
13-14) After the pallet leaves the refrigerator, the refrigerator is left slowly and with its feet evenly on the floor.

Cabinets on legs:
Cabinets on legs require an even, solid floor. Cabinets on legs are levelled by turning the internal part of the feet.
Cabinets on castors:
Cabinets on castors require a level, even and solid floor to provide a stable foundation. After correctly
positioning the cabinet, the two brakes on the front castors must be applied.
The cabinets are equipped with a chamber for re-evaporation of the condensation water on top of the
cabinets. This equipment is intended for the amount of condensation water that accumulates on average
witha maximum of 72 door openings per day according to ISO 22041.
The actual amount of condensation water may vary depending on usage and ambient conditions. If the
number of door openings per day exceeds 72, or the condensation water pan overflows due to other usage
factors, the user must use the product strictly under the specified conditions to prevent overflow. If the
amount of condensation increases despite not changing the usage or the ambient conditions,the cabinet may
have a defective door seal or a door that does not closeproperly.
6) Condensation Water Re-evaporation

HOSHIZAKI EUROPE

The 220-230 V/50 Hz mains connection is established by plugging the provided cable with appliance
connector into a socket with earthed protective contact.
30 mA residual current circuit breaker is essential.
There may be special regulations from your local energy supply company regarding earthing measures that
must be observed.
In order to achieve the necessary air circulation in the interior, only store goods within the corresponding
markings (loading marks) and on the shelves (never on the floor or in front of the air outlets).
No electrical cabinets may be operated inside the cabinet.
8) Instructions for Daily Use
During working with the electrical equipment, the cabinet must
always be disconnected from the mains by pulling out the power
plug. It is NOT sufficient to switch off the cabinet with the ON/OFF
button as parts of the cabinet are still live
7) Electrical Connection

The cabinet must be cleaned regularly. The intervals depend on the usage and level of soiling (at least
annually).
Before carrying out any cleaning or maintenance operations, unplug the unit
Don’t touch or wet the machine compartment parts. This could result in failure or breakdown.
To prevent possible damage, don’t clean the plastic parts with water above 40° C or in a
dishwasher.
Interior & Exterior of Cabinet and Shelves
Clean the interior and exterior at least once a week for sanitary use.
Clean off the interior and exterior of cabinet with a soft cloth soaked in cold or warm water
containing the proper amount of neutral cleaner and wrung dry. Don’t use a water jet to clean
the machine compartment.
Chemical agents other than neutral cleaner might cause damage to the interior and exterior
surfaces.
Any remaining detergent will damage metal or plastic surfaces. Use a soft cloth dampened with
warm water to wipe it off.
Don’t use the following items, they could damage painted or plastic surfaces:
-Polishing powder, alcohol, thinner, benzene, acidic or alkaline detergent, hot water,
petroleum, soap powder, metal scourer or brush, etc. Especially detergent to clean grease
on ventilator or microwave
Note: Some solutions other than the above may also
damage painted or plastic surfaces. Immediately stop
using such solutions if they cause any problems!
The door gasket and its contact surface get soiled easily. Clean every surface of these parts
thoroughly. Remnants of food will accelerate aging.
Use a cloth to wipe off any water staying inside the cabinet.
9) Cleaning and Maintenance

Condenser
Use vacuum cleaner or a soft brush to remove dust and stains from the condenser.
Warning: If users clean the condenser with hard brush,
such as dishwasher brush, the coating of condenser may
peel off.
*Air Filter
To prevent deformation do not wash the air filter hot water above 40°
Plastic mesh air filters remove dirt or dust from the air and keep the condenser from getting
clogged. If the filters get clogged, the refrigerator/freezer’s performance will be reduced.
Check the filters at least twice a month. When clogged or when the temperature controller shows
“cH" use warm water and a neutral cleaner to wash the filters. Don’t operate the unit with the air
filters removed, or the condenser will get clogged, resulting in failure.
1) Open the front panel and remove the air filter. To prevent injury, don’t touch the condenser fins
directly.
2) Wash the air filter carefully with cold or warm water containing the proper amount of neutral
cleaner. Rinse and dry the air filter thoroughly.
3) To refit the air filter, put the two tabs into the heat exchanger or fins in condenser and tightly
attach the air filter over the condenser.
Note (*): Air filter is used in Premier W80, Premier 60 for this manual
