B.V.

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

+30°C with %55 RH

+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.

1) Safety Information

HOSHIZAKI EUROPE

B.V.

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.

HOSHIZAKI EUROPE

B.V.

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

HOSHIZAKI EUROPE

B.V.

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

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

B.V.

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
