3.4.4 Appliance Description
Food transport trolleys are equipped with heated bain-marie wells and heated cupboard compartments. They
hold up prepared meals in Gastronorm containers and keep them warm. There is also the opportunity to use
heated cupboard compartments in combination with a cold storage plate as a cooling compartment. Due to
the thermal insulation of the mobile bain-marie, the bain-marie wells that are placed above and the adjacent
heated cupboards are not affected.
The bain-marie wells are filled with water up to the fill level indicator and warmed up by a foil heater. The
generating water vapour heats up the inserted Gastronorm containers. The heating element and electrical
parts are easy to be accessed and can be dismantled without any problems. The bain-marie wells can be
emptied by the water drain taps after the operation.
The operating temperature for each bain-marie well and each heated cupboard compartment can be chosen
separately. The thermostats are fitted on the front side of the food transport trolley that is used to set the op-
erating temperature continuously between 30°C and 95°C for each bain-marie well, and continuously be-
tween 30°C and 80°C for each cupboard compartment. Thereby the digits on the thermostats help to allocate
to the corresponding bain-marie wells and heated cupboard compartments.
The cover elements of both models with a sliding lid (SPTW-2/EBF-S and SPTW-2/EBF-S) can be opened
back and forth. When closing the covering elements are mechanically locked in the end position. The lever
for cover release can be operated with one hand. To loosen the locking you haveto push down the lever.
The cover elements of the models with a hinged lid (SPTW-2/EBF-K and SPTW-2/EBF-K) can be opened to
the right and left. The smaller 1/3 element with a removable perforated plate is opened to the left and can be
locked with two supports in a 180° position. It can be used for serving plates, filling of soup bowls and to hold
up ladles. The bigger 2/3 element is opened to the right and it is equipped with a condensate collecting
channel on the inner side. When it is opened to an angle of 270° it can be used to hold gastronorm container
lids. It is not possible tolockit in an angle of 180°.
3.4.5 Equipment and optional accessories
The following parts can be applied as optional accessories for the food transport trolley:
§Folding shelf
Folding shelves made of stainless steel are designed to hold up crockery items. They can be fitted ei-
ther on
the lateral side or on the front side of themodels. Only authorised staff may fix the folding shelves to
the appliance. To do this, they need a welding device. It is not permitted to put heavy loads onto fold-
ing shelves. During transport, they must be folded up. The folding shelves can be folded up by lifting
them slightly up and raising them to an angle of 90°. There is a risk of crushing your fingers when
folding up and locking.
§Cold storage plate
The cold storage plates are filled with approximately 4 litres of cooling brine. Nutritionally, plastic
housings and coolant are totally harmless. Dimensions 530 x 325 x 30 mm, total weight 4.5 kg.
During the phase transition from the solid to the liquid state about 70 % of the available cooling power
is released. If only liquid cooling brine is used, the power will be only 30 % of themaximal possible
value.
When freezing, cold storage plates have to be stored horizontally and with sufficient distance to each
other, since otherwise centrally located cold storage plates cannot be cooled sufficiently even after 24
hours. During the freezing process, the cold storage plates bulge due to the volume increase of the
cooling brine. This is a natural process that can be reversed by the heating in the food transport trol-
ley.
It is not useful to cool down the cooling brine below -18°C because too low temperatures slow down
the liquid-to-solid phase transition. The maximal permitted surface temperature of the cold storage
plates is +50°C. Cold storage plates are not suitable for the cleaning in dishwashers.
§Sneeze guard
The sneeze guard serves as a hygienic protection when serving food. In addition, the integrated heat
bridge warms the meals from above and prevents the formation of condensation on thetransparent
sneeze guard.

4 Transport, Putting into Operation and Decommissioning
4.1Transport
ATTENTION Appliance damages caused by improper transport
In the case of off-site transport in a vehicle such as a lorry, the appliances
should be secured properly. The total brakes are not sufficient as a transport
securing method.
If the appliances are not secured properly, there is a risk of damage to proper-
ty and persons caused by squashing.
During transport, secure all the individually standing appliances using corre-
sponding transport securing devices.
The food transport trolley is delivered as an assembled unit, i.e. it is completely assembled including the
heating.
When loading, use only hoists and load lifting devices approved for the weight of thefood transport trolley.
Only thetransport vehicles may be used that are approved for the weight of the appliance.
According to the valid purchase contract, the scope of delivery is specified in the shipping documents at-
tached to the delivery item.
4.2 Putting into Operation
DANGER Hazardous electrical voltage
The electrical voltage may be considerably dangerous to limb and life of per-
sons and lead to injuries.
Before putting the appliance into operation check, whether the power supply
indicated on the rating plate (230V / 50 Hz) corresponds to the local power
supply. Otherwise, do not put the appliance into operation.
Do not use any extension leads in wet areas.
Remove the original packing and check, whether the appliance is complete and undamaged. In no case put
a defective appliance into operation and inform the supplier immediately.
Always place the food transport trolley on firm and level floors when unpacking and operating it. Apply the to-
tal brakes on both swivel casters to secure the appliance against rolling away.
INFO Disposal of packing material
The packing consists of recyclable materials and can be disposed of appro-
priately. Thereby, the different materials are to be separated and disposed in
an environmentally compatible manner. In any case, the local bodies respon-
sible for disposal are to be involved for this purpose
The food transport trolley should be thoroughly cleaned with a soft cloth before putting it into operation for
the first time. Before the appliance is put into operation it must be clean and dry.
The following appliance functions must be checked before putting it into operation:
§the functioning of the total brakes
§the functioning of the operating elements and heating.

4.3Storage and Recycling
Temporary storage must take place in a dry and frost-free environment. The food transport trolley must be
kept covered with a suitable covering material to be protected against dust ingress.
The appliance kept in the storage location must be checked for damages and corrosion every 6 months.
NOTE Condensed water formation
Ensure that there is sufficient ventilation and no large temperature fluctuations
in the storage location to avoid condensed water formation.
Before the appliance is taken back into operation it must be clean and dry.
If the food transport trolley is recycled, all operating and auxiliary materialsmust be disposed in an environ-
mentally compatiblemanner. The recyclablematerials must be properly separated and disposed in an envi-
ronmentally compatible manner according to the local Waste Disposal Regulations. In any case, the local
bodies responsible for disposal are to be involved for this purpose. Separate the reusable materials of the
appliance (casters and plastic parts) before disposing or send the appliance to a recycling centre. Dispose
the electronics at corresponding collection centres.
We offer our customersto dispose their waste appliances. Please contact us or one of our distribution part-
ners.
Packaging and packing material can be sent to the recycling centre by indicating the waste disposal contract
number. If you do not have the valid waste disposal contract number, you can ask for it at HUPFER®- Ser-
