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 regu-

lations

Working on the system

■Isolate the system from the power sup-

ply (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 recon-

nection.

!Please note

Electronic assemblies can be dam-

aged by electrostatic discharge.

Prior to commencing any work,

touch earthed objects such as heat-

ing or water pipes to discharge

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.

Safety instructions

6153974

Danger

Floors that are wet or damp with

water or glycol based liquids can

cause injury due to slipping and fall-

ing.

■Keep the floor clean and dry dur-

ing installation and maintenance

work.

■Wear non-slip shoes.

Danger

Broken-off fragments of insulation

material can cause death by suffo-

cation if inhaled or swallowed.

■Do not let children play in the

installation room.

■Keep the installation room clean

after installation and maintenance

work.

Repair work

!Please note

Repairing components that fulfil a

safety function can compromise the

safe operation of the system.

Replace faulty components only

with genuine Viessmann spare

parts.

Auxiliary components, spare and wearing parts

!Please note

Spare and wearing parts that have

not been tested together with the

Dispose of component correctly.

Dispose of component at a suitable collec-

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.

Information

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.

Product information

Installation

!Please note

To prevent material losses, install the heating

water buffer cylinder in a room free from the risk

of frost and draughts.

Otherwise the heating water buffer cylinder will

need to be drained when not in use and there is

a risk of frost.

Note

Placing the heating water buffer cylinder on a plinth will

make the room easier to clean.

Preparing for installation

Siting

AType plate

B3 adjustable feet

3. Insert the adjustable feet into the legs as far as

they will go. Use the adjustable feet to level the cyl-

inder body.

Note

Only use one or two of the adjustable feet to level the

cylinder body. At least one of the adjustable feet must

remain fully screwed in.

Installation

Fig. 4

1. Route the leads of all available thermometer sen-

sors to the cylinder through the small apertures in

the thermal insulation mat.

2. Guide the upper thermometer sensor through the

lifting eye, insert it into the clamping bracket as far

as it will go and tighten the wing nut.

Secure the lower thermometer sensor (if available)

in the clamping bracket at the base of the cylinder.

3. Release the nuts.

4. Push the clamping system onto the threaded studs

and align.

5. Tighten the nuts.

6. Depending on where the sensor is being fitted:

Insert the thermometer sensors and cylinder

temperature sensors into clamping systems A

as far as they will go.

Note

Never wrap insulating tape around the sensors.
