Please follow these safety instructions closely to

prevent accidents and material losses.

Safety instructions explained

Danger

This symbol warns against the risk of injury.

!Please note

This symbol warns against the risk of material

losses and environmental pollution.

Note

Details identified by the word "Note" contain additional

information.

Target group

These instructions are exclusively intended for quali-

fied contractors.

■Work on electrical equipment may only be carried

out by a qualified electrician.

Regulations to be observed

■National installation regulations

■Statutory regulations for the prevention of accidents

■Statutory regulations for environmental protection

■Codes of practice of the relevant trade associations

■Relevant country-specific safety regulations

Working on the system

■Isolate the system from the power supply (e.g. by

removing the separate fuse or by means of a mains

isolator) and check that it is no longer live.

■Safeguard the system against reconnection.

■Wear protective clothing.

!Please note

Electronic assemblies can be damaged by elec-

trostatic discharge.

Prior to commencing any work, touch earthed

objects such as heating or water pipes to dis-

charge static loads.

Danger

Hot surfaces can cause burns.

■Before maintenance and service work, switch

OFF the appliance and let it cool down.

■Never touch the hot surfaces of uninsulated

pipes and fittings.

Danger

Floors which are wet, damp or covered in fluids

containing glycol present a risk of injury through

slipping and falling.

■When carrying out installation and mainte-

nance work, ensure that the floor is kept clean

and dry.

■Wear non-slip shoes.

Danger

Breathing in or swallowing broken-off fragments

of insulating material may result in death by

asphyxiation.

■Do not allow children to play in the installation

room.

■Clean the installation room after installation

and maintenance work.

Repair work

!Please note

Repairing components that fulfil a safety func-

tion can compromise the safe operation of the

system.

Replace faulty components only with genuine

Viessmann spare parts.

Warning of material losses and environ-

mental pollution

Live electrical area

Pay particular attention.

■Component must audibly click into place.

■Acoustic signal

■Fit new component.

■In conjunction with a tool: Clean the sur-

face.

Dispose of component correctly.

Dispose of component at a suitable collec-

tion point. Do not dispose of component in

domestic waste.

Intended use

The appliance is only intended to be installed and

operated in sealed unvented systems that comply with

EN 12828 / DIN 1988, or solar thermal systems that

comply with EN 12977, with due attention paid to the

associated installation, service and operating instruc-

tions. DHW cylinders are only designed to store and

heat water of potable water quality. Heating water buf-

fer cylinders are only designed to hold fill water of pot-

able water quality. Only operate solar collectors with

the heat transfer medium approved by the manufac-

turer.

Intended use presupposes that a fixed installation in

conjunction with permissible, system-specific compo-

nents has been carried out.

Commercial or industrial usage for a purpose other

than heating the building or DHW shall be deemed

inappropriate.

Any usage beyond this must be approved by the man-

ufacturer for the individual case.

Disposal of packaging

5838620

Incorrect usage or operation of the appliance (e.g. the

appliance being opened by the system user) is prohibi-

ted and results in an exclusion of liability.

Incorrect usage also occurs if the components in the

system are modified from their intended use (e.g.

through direct DHW heating in the collector).

Adhere to statutory regulations, especially concerning

the hygiene of potable water.

Siting information

!Please note

The thermal insulation must not be able to come

into contact with naked flames.

Exercise caution when welding and soldering.

!Please note

To prevent material losses, site the DHW cylin-

der in a room free from the risk of frost and

draughts.

When not in use, the DHW cylinder must be

drained if there is a risk of frost.

Use the adjustable feet to level the DHW cylinder.

Note

Never extend the adjustable feet beyond a total length

of 35 mm.
