2 Safety Instructions

2.1 Introduction

The chapter on safety instructions describes the risks associated with the appliance in terms of product liabil­ity (according to the EU Machinery Directive).

2.2 Warning Symbols Used

Symbols are used in these operating instructions to point out the dangers that can occur while operating or
cleaning the appliance. In both cases, the symbol provides information on the type and circumstances of
danger.

The following symbols can be used:

General hazardous area

Hazardous electrical voltage

Risk of hand injuries

Risk of crushing

Risk of hot surfaces

Wear hand protection

2.3 Safety Instructions for Appliance Safety

Safe operation of the appliance depends on appropriate and thorough use. Negligent handling of the appli­ance can lead to danger to life and limb of the user and / or third parties as well as hazards to the appliance
itself and the other operator's property.

2.3.1 Safety instructions for all appliances

The following points are to be observed to ensure the appliance safety:

 The appliance may only be operated when it is in perfect condition with regards to technical stan-

dards.

 All the operating and actuating elements must be in a perfect and functionally reliable condition with

regards to technical standards.

 Modifications or retrofits of the equipment are only permitted in consultation with the manufacturer

and on receipt of his written agreement.

 In no case may people sit or stand on the appliance. Transport of persons is not permitted.
 Before loading, the crockery dispensing height must be adjusted to the kind of crockery used.
 To avoid injuries to the hands, care should always be taken to ensure that the crockery dispensing

height does not fall below the upper rim of the housing.

 Never push the stacking platform down manually into the compartment (e.g. for cleaning). There is a

risk of injury, if the stacking compartment is released.

 The appliance is provided exclusively for manual transport. Mechanical transport is not permitted.

Risk of injury and damage.

Chapter 2 Safety Instructions
Page 10 Safety Instructions for Appliance Safety

 Release both total brakes before commencing transporting. Moving the appliance with the total

brakes locked can damage the chassis.

 Transport should only be undertaken over level floors. Moving the appliance over very uneven floors

can damage the chassis.

 Transport over inclined planes or steps is not permitted.
 When approaching walls and moving round obstacles always pay attention to persons in the way.

Risk of injury.

 When transporting the appliance, always hold both handles with your hands. Never let go of the ap-

pliance while moving it.

 When transporting the appliance, do not move it faster than a walking pace. Heavily laden universal

crockery dispensers are difficult to brake and steer. If necessary, ask for assistance when transport­ing the appliance.

 If the universal crockery dispenser tips over due to outside influences or inattention, never catch it

manually. Risk of injury.

 Do not stop the appliance on sloping floors.
 After stopping, the appliance should be secured against rolling away by means of both total brakes

being applied.

 In the case of off-site transport in a vehicle such as a lorry, the appliances should be secured prop-

erly. The total brakes are not sufficient as a transport securing method.

2.3.2 Additional safety instructions for heated appliances

 Only insert the stacking platform with the basket opening facing downwards.
 Heated universal crockery dispensers are intended for dispensing heated crockery. Their use for

cooking food and keeping it warm or for room heating is not permitted.

 The crockery temperatures can exceed the permitted maximum temperatures of 149°F (65°C) for

touchable appliance surfaces. Always wear protective gloves when dispensing hot crockery. Risk of
burning.

 The use of heated models in customer-service areas (for example, at self-service counters) is only

permitted by trained staff even when the temperature setting has been reduced. It is always neces­sary to ensure that the crockery on the top which is about to be taken out is at a non-critical tempera­ture of less than 131°F (55°C) and that the temperature setting on the appliance can't be altered.
Moreover, make sure that even if the crockery is to be taken out of the dispenser at the set tempera­ture very quickly (e.g. at busy meal times) it can always be done safely.

 During operation of the appliance, never reach into it and touch the heating element with the fingers.

Risk of burning.

 Plastic crockery, top and bottom parts of plastic insulated sets and plastic-coated items for keeping

food warm should not be stored nor warmed up in heated universal crockery dispensers. Owing to the
high temperatures of the heating elements, the plastics can melt and catch fire.

 If the cover made of stainless steel is used, its outer edges can heat up to over 149°F (65°C). There-

fore, only touch the cover with protective gloves to avoid skin irritations.

 The base plate and used air from the base outlets can become very hot. The appliance should not be

operated on fibre-based floor coverings (e.g. carpets, mats).

 The positions of the guide rails must be adjusted to the size of the crockery items before loading.
 Before transporting, switch off the appliance, pull out the mains plug and insert it into the holder pro-

vided.

 Forceful straining of the connecting cable can lead to damage to the internal line. Risk of fire.
 Never pull the mains plug out of the socket by the connecting cable. The standard models of

HUPFER

plug this plug only sticks insignificantly out of the socket and so cannot be damaged by being hit at
the side. If the appliance is moved without pulling out the mains plug beforehand, the socket can be
severely damaged or even pulled out from the wall as a result of leverage arising from overstretching
of the connecting cable.

Safety Instructions for Cleaning and Care Page 11

 Never move the appliance by pulling by the connecting cable.
 If the mains plug has come into contact with water it must be dried before inserting it into the socket.

Danger to life.

 Damaged mains plugs or connecting cables are to be replaced by authorised personnel before the

appliance is reused.

 Do not use any extension cables in wet and damp areas.
 Only insert mains plugs into suitable sockets. If the mains plug does not fit, the connecting cable of

the appliance is to be retrofitted by authorised specialist staff.

 The use of socket adapters is not permitted. Risk of fire.
 Do not clean the appliance with steam-jet or high-pressure washers. The appliance must be taken out

of operation and switched off at the mains beforehand in any area where steam-jet or high-pressure
washers are to be used.

2.4 Safety Instructions for Cleaning and Care

The following points shall be observed when carrying out any cleaning and maintenance operations:

 For reasons of hygiene the cleaning instructions shall be strictly observed.
 Take the appliance out of operation before starting the cleaning process. Pull out the mains plug and

insert it into the holder located on the appliance.

 For cleaning, the appliance must be out of operation and cooled down sufficiently.
 Do not clean the appliance with steam-jet or high-pressure washers. The appliance must be taken out

of operation and switched off at the mains beforehand in any area where steam-jet or high-pressure
washers are to be used.

 Even appliances without an electrical connection should not be cleaned with running water or pres-

surised water.

2.5 Safety Instructions for Troubleshooting

The following points shall be observed when carrying out any maintenance and troubleshooting operations:

 All troubleshooting work should only be carried out by authorised specialists.
 When carrying out troubleshooting work, it must be ensured that the appliance is switched off. When

operating on the electrical installation, the appliance is to be switched off at the mains and secured
against reactivation.

 The local applicable Accident Prevention Regulations must be observed.
 Defective components should only be replaced with original parts.

2.6 Notes on Specific Hazards

Electrical energy

 All work on the electrical installations should only be carried out by a certified electrician or by author-

ised specialists under supervision and monitoring of a certified electrician according to the certain
electro-technical regulations.

 The appliances that inspection, maintenance and troubleshooting work is performed on must be

switched voltage free on and secured against reactivation, when the voltage is not required for this
kind of work. This must only be carried out by a certified electrician.
