3 Description and Technical Data
3.1 Performance Description
The food transport trolleys are a complete system for the transport and distribution of meals. They hold up
prepared meals and keep them warm. Food in gastronorm containers can be either put into bain-marie wells
or gastronorm containers, on grids or into baskets in heated cupboards. When switched off and with the use
of a cold storage plate, the cupboard compartments can also be used for cold meals and cold side dishes,
e.g. salads, bread, cold cuts and desserts. Bain-marie wells and heated cupboards are thermally insulated
from each other.
Food transport trolleys are mainly used to store, transport for short distances and distribute hot meals. They
can be used everywhere, where the use of tray systems is not efficient and thefree choice of a portion size
is a particularly important decision criterion. The number of persons depends on the number of menu com-
ponents.
The heated plate dispensing tube with cover, the storage place for ladles and the neutral compartment pro-
vide sufficient space-saving storage options to store and transport all of the utensils required by the operat-
ing staff as well as all of the crockery/cutlery required for the guest in a single appliance.
3.2 Proper Use
Food transport trolleys are intended for storing hot meals and for keeping meals warm. It is not possible to
heat up cold meals or to cook products which have been introduced in the warm state.
Food transport trolleys are only intended for the transport of meals in gastronorm containers or portioned
meals on grids or in baskets.
The plate dispensing tube of the food transport trolley is intended for dispensing round crockery items made
of porcelain or toughened glass. It is also possible to transport crockery, cutlery and napkins in suitable
transport containers or on trays in the neutral compartment.
Food transport trolleys are only intended for the transport for short distances. When transporting for longer
distances, connect the appliance to a power supply, switch the heating on and reheat the meals at regular in-
tervals.
When cooling meals or the components itis necessary to comply with the respective legal directives on food
storage (duration and temperature).
The intended use means the predetermined procedures, compliance with the indicated specifications and
use of the delivered or additionally available original accessories.
Any other use of the appliance is considered as unintended use.
3.3 Improper Use
It is not permitted to use foodtransport trolleys for cooking food or keeping it warm, for room heating and
drying the crockery.
The maximum duration of transport of hot meals shall in no case be exceeded between two heating stages.
Do not transport any loads on the hinged lids of the appliances, because transported objects are not secured
to prevent them falling down.
Transport of persons is not permitted.
In no case may people sit or stand on the appliance.
It is not permitted to heat dry the bain-marie wells
The plate dispensing tube is not designed to heat and store plastic crockery, top and bottom parts of plastic
insulated sets or plastic-coated items used to keep food warm. Owing to the high temperatures of the heat-
ing elements, the plastics canmelt and catch fire.
Any other use, especially loading the food transport trolley with other loads as given, is not permitted.
The manufacturer and suppliers are not liable for any consequential damage resulting from unintended use.
No liability is assumed and no warranty claims can be submitted for damages caused by improper use.

3.4.2 Appliance Description
Food transport trolleys are equipped with two heated bain-marie wells and two heated cupboard compart-
ments. They hold up prepared meals in Gastronorm containers and keep them warm. It is also possible to
switch off the heated cupboard compartments and use these in combination with a cold storage plate as
cooling compartments. The thermal insulation of the mobile bain-marie ensures the efficacy of the bain-marie
wells above these compartments and the adjacent heated cupboards is not impaired.
The bain-marie wells arefilled with water up to the fill level indicator and heated by a foil heater. The gener-
ating 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. Using the continuously adjustable thermostats located on the front of the food transport trolley it
is possible to separately adjust the operating temperature of each individual bain-marie well and cupboard
compartment. Digits on the thermostats indicate the corresponding bain-marie wells and heated cupboard
compartments.
The lids can be opened to the left and the right. The smaller 1/3 element with a removable perforated plate
opens to the left and is locked in position at 180° by two supports. 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 to lock it in an angle of 180°.
The plate dispensing tube holds clean plates made of porcelain or toughened glass in an adjustable, spring-
loaded guide basket. Special springs ensure crockery items are automatically and constantly moved up the
entire lift to a uniform dispensing height. The ergonomically favourable dispensing height can be adjusted
within a limit to persons of different height. The plastic cover used to cover the plate dispensing tube effec-
tively protects loaded crockery against dust and condensation even during relatively long periods of tempo-

rary storage. When fitted in position the cover reduces upward heat loss and lowers the time required to heat
the inserted crockery as well as prolongingthe time warm crockery takes to cool down.
3.4.3 Equipment and optional accessories
The following parts can be applied as optional accessories for the food transport trolley:
§Folding shelf
The stainless steel folding shelf is designed to hold items of crockery; it is designed to be fitted to the
end of the appliance. Authorised staff only are permitted to fit folding shelves to the appliance. To do
so, requires a welding machine. It is not permitted to put heavy loads on to folding 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 the maximal 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 heatingin 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.
§Gastronorm containers and bowls of various sizes
§Support bars for wells, length 325 mm, made of stainless steel
§Support bars for wells, length 530 mm, made of stainless steel
§Basket GN 1/1, 530 x 325 x 70 mm, Mesh width 26 mm, stainless steel, plastic-coated
§Swivel casters made of stainless steel, Ø = 125, 160 or 200 mm with and without total brakes, plate
attachment
§Fixed caster made of stainless steel, Ø = 125, 160 or 200 mm, plate attachment
The part numbers of the special accessories can be found in the spare parts catalogue and order lists avail-
able online.

4 Transport, Putting into Operation and Decommissioning
4.1 Transport
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 the food transport trolley.
Only the transport 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
DANGERHazardous 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 / 50/60 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 securethe appliance against rolling away.
INFODisposal 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.

4.3 Storage 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.
NOTECondensed 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 materials must be disposed in an environ-
mentally compatible manner. The recyclablematerialsmust be properly separated and disposed in an envi-
ronmentally compatible manner according to the local WasteDisposal Regulations. In any case, the local
bodies responsiblefor disposal areto 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 customers to 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®-
Service.

5 Operation
WARNING Risk of hot surfaces
If thethermostat is set to the level 3 and higher, the permitted maximum tem-
perature of 149°F (65°C) for touchable appliance surfaces can be exceeded.
Direct contact with your skin can cause burns.
Only instructed staff may operate the appliance. Wear suitable protective
clothing.
ATTENTION Damage to property
A layer of scale acts as thermal insulation and can lead to a heat accumula-
tion above the tubular heating element as well as cause damage to the well
base. There is a risk of corrosion under the scale layer.
If you heat the bain-marie wells dry, they get warped and micro-cracks form.
This can result in a total damage.
Only operate the foodtransport trolley when it is clean.
ATTENTION Exposed springs
When pressing down the guide basket manually,the springs are exposed.
Reaching into the gaps of the exposed springs may cause hand injuries.
Never press the guide basket down manually.
The food transport trolley must be checked for external visible damages and defects before each operation.
Before putting the appliance into operation, the heated cupboards must be clean and the bain-marie wells
must be cooled down, clean and without scale deposits. If required, bain-marie wells that have been already
put into operation and completely drained off must cool down for some time.
Appliances equipped with foil heating may not be heated without water in the bain-marie well.
5.1 Arrangement and Function of the Operating Elements
The operating elements of the food transport trolley are arranged on the front side of the appliance.
The digits on the thermostats can be allocated to the bain-marie wells and the heated cupboards.

5.2 Adjusting the plate dispensing tube
WARNING Risk of hot surfaces
The internal surfaces of the heated appliances can become hot during opera-
tion and only cool down slowly in the air.
To adjust the guide basket, allow the appliance to cool down sufficiently with
the cover removed.
ATTENTION Exposed springs
When pressing down the guide basket manually, the springs are exposed.
Reaching into the gaps of the exposed springs may cause hand injuries.
Never press the guide basket down manually.
Be careful when hooking and unhooking the springs. When adjusting springs
on sharp edges, pay particular attention to the ends of the tension springs.
The adjustments should only be carried out on the appliances which are switched off, disconnected from the
power supply and cooled down (room temperature).
Before starting work, always check it the plate dispensing tube of the food transport trolley is correctly set for
the crockery to be used.
The following functions are to be checked separately:
§The vertical guide of the plates, in order to prevent any risk of injury to the operating staff if the crock-
ery guides are set too far apart or too close together.
§The dispensing height, so that the staff cannot suffer injury or become trapped and no breakage of
crockery can occur.
Basically, the appliance must be adjusted if at least one of the following crockery parameters alters:
§Diameter
§Height
§Stack height
§Weight.
5.2.1 Crockery guide adjustment
Before loading, the crockery guides must be adjusted to the diameter of the crockery items and fixed in the
locking positions provided.
If the crockery guides are set too far apart from each other, the crockery stack can become wedged under
the upper plate due to the possible high tilt angles, and can injure the operating staff when released.
If the crockery guides are set too close, the plates can become jammed and can injure people when re-
leased suddenly.
Too small crockery items cannot be guided properly and, therefore, should not be used.
