DESCRIPTION

1.2 Mode of operation

1.2.1 c5-2 boiler element

The c5-2 boiler element is an autonomous hot water/steam module with a large-volume boiler, enabling a high throughput of beverages.

The c5-2 boiler element is normally connected directly to the water mains, but it can also be operated with canisters.

1.2.2 "Temperature probe" option

In combination with an additionally installed temperature probe, the final temperature of the medium to be heated by the c5-2 / c5-2C can be monitored.

Once the final temperature is achieved, the supply of steam is automatically stopped.

SAFETY INSTRUCTIONS

2 Safety instructions

2.1 Warnings

2.1.1 Warning symbols used (depending on nationality)

The following warning symbols can be affixed.

Low voltage

• Warning of dangerous elec-

trical voltage.

• Electric shocks can lead to

serious injury or death.

• Only authorised technical

personnel may perform work on electrical installations.

• The technical safety instruc-

tions must be followed.

2.1.2 Places where warning symbols are affixed (depending on nationality)

NOTE

• The equipment comes sup-

plied with warning symbols (stickers) affixed wherever appropriate.

• If any of the warning sym-

bols should fall off during operation or following cleaning work, the operator must stick these warning symbols back again immediately.

2.1.3 Safety information in these Operating Instructions

• Unplug c5-2 boiler element

from the mains before carrying out any work on electrical installations.

Hot surface / hot internal components

• Warning of heat which could

lead to injury.

• Allow hot surfaces and components to cool before carrying out any work on these component parts.

• If necessary, wear heat-resistant gloves.

In these Operating Instructions, you will find the following three levels of safety information:

n Level 1

WARNING

• A warning refers to signifi-

cant hazards. Failure to follow the relevant safety instruction could lead to injury or death.

SAFETY INSTRUCTIONS

Depending on the type of danger, instead of STOP, one of the following symbols could be combined with the word WARNING.

WARNING

• Warning of electric shock.

WARNING

• Warning of heat.

n Level 2

CAUTION

• The CAUTION symbol

stresses important instructions. Failure to observe these instructions could lead to damage to the equipment or to other material assets.

n Level 3

NOTE

• Notes contain additional in-

formation aimed at raising the general level of safety and at lightening the user’s workload.

2.2 Basic safety instructions

2.2.1 Proper use

2.2.1.1 General

Proper use includes, in addition to the specific provisions set out below, observing these Operating Instructions and complying with the supplier’s obligatory maintenance and repair instructions.

2.2.1.2 c5-2 boiler element

The c5-2 boiler element is used solely to output hot water or steam and to heat and froth milk.

No other use of the c5-2 boiler element will be deemed to be proper.

2.2.2 Specific hazards and instructions

2.2.2.1 c5-2 boiler element

WARNING

• Hot air comes out from the

bottom of the steam outlet. There is a danger of scalding.

• The bottom of the steam

outlet is hot after it has been giving off steam. There is a danger of burns.

• Hot liquid comes out from

the bottom of the hot water outlet. There is a danger of scalding.

• The bottom of the hot water

outlet is hot after it has been dispensing liquid. There is a danger of burns.

WARNING

• Never interfere with the

electricity supply connection or modify it. This could result in fatal injury.

• Never remove the screw-

mounted covers. There is a danger of fatal injury upon contact with live components.

SAFETY INSTRUCTIONS

CAUTION

• Never interfere with the wa-

ter mains connection or modify it. There is a danger of flooding.

• Only operate the c5-2 boiler element in covered locations, avoid places where there is a risk of water splash. There is a risk of damage.

• Never spray the c5-2 boiler element with a water hose during cleaning. There is a risk of damage.

• Never lift the c5-2 boiler element by the drip tray.

• If the internal relief pressure valve is actuated due to improper increase of pressure, switch the c5-2 boiler element off immediately. Secure the c5-2 boiler element against unintentional switching on and report to Customer Support.

• The c5-2 boiler element must be disconnected from

the water supply after it has been switched off, e.g. for the overnight period of inactivity, i.e. it is imperative that the tap is closed.

SAFETY INSTRUCTIONS

2.2.3 Personal safety

NOTE

• Regardless of type configu-

ration, the c5-2 boiler element should not be used in large kitchens.

• Electrical equipment which does not have adequate electro-magnetic protection should not be operated close to the c5-2 boiler element.

• The drip tray serves solely to collect drip water. It must not be used as a sink.

• Ideally, do not leave the key in the key-operated switch.

WARNING

If handled improperly, the c5-2 boiler element could cause serious or fatal injury.

Anyone using and maintaining the c5-2 boiler element must be trained in the correct handling of the c5-2 boiler element and must have read and understood the safety instructions in these Operating Instructions before starting to use or maintain the c5-2 boiler element.

WARNING

Never operate the c5-2 boiler element in a damaged condition.

WARNING

Never modify or remove any safety mechanisms.

Do not disable any safety mechanisms by modifying the c5-2 boiler element.

If there are any warning symbols affixed to the c5-2 boiler element (dependent on nationality), never remove these. Replace any lost or defective warnings symbols immediately.

Report any irregularities to your superior immediately, especially if they affect safety.
