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 author-
ised contractors.
■Work on the refrigerant circuit may only be carried
out by authorised refrigeration engineers.
■Work on electrical equipment must only be carried
out by a qualified electrician.
■The system must be commissioned by the system
installer or a qualified person authorised by the
installer.
Regulations to be observed
■National installation regulations
■Statutory regulations for the prevention of accidents
■Statutory regulations for the protection of the envi-
ronment
■Codes of Practice of the relevant trade associations
■All relevant safety regulations as defined by DIN, EN,
DVGW, VDE and locally applicable standards
aÖNORM, EN and ÖVE
cSEV, SUVA, SVTI, SWKI and SVGW
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'.
Note
In addition to the control circuit there may be several
load circuits.
Danger
Contact with 'live' components can result in
severe injuries. Some components on PCBs
remain 'live' even after the power supply has
been switched off.
Wait at least 4 minutes before removing equip-
ment covers, to allow the voltage to dissipate.
■Safeguard the system against reconnection.
!Please note
Electronic assemblies can be damaged by elec-
trostatic discharge.
Prior to commencing work, touch earthed
objects such as heating or water pipes to dis-
charge static loads.
Repair work
!Please note
Repairing components that fulfil a safety func-
tion can compromise the safe operation of your
system.
Replace faulty components with genuine
Viessmann spare parts.
Auxiliary components, spare and wearing parts
!Please note
Spare and wearing parts that have not been tes-
ted together with the system can compromise its
function. Installing non-authorised components
and making non-approved modifications or con-
versions can compromise safety and may inva-
lidate our warranty.
For replacement, use only spare parts supplied
or approved by Viessmann.

Intended use
The appliance is only intended to be installed and
operated in sealed unvented heating systems that
comply with EN 12828, with due attention paid to the
associated installation, service and operating instruc-
tions.
The appliance may only be used for heating DHW.
The range of functions can be extended with additional
components and accessories.

Intended use presupposes that a fixed installation in
conjunction with permissible, system-specific compo-
nents has been carried out.
Commercial or industrial use for purposes other than
domestic hot water heating shall be deemed inappro-
priate.
Any usage beyond this must be approved by the man-
ufacturer in each individual case.
Incorrect usage or operation of the appliance (e.g. the
appliance being opened by the system user) is prohibi-
ted and will result in an exclusion of liability. Incorrect
usage also occurs if the components in the heating
system are modified from their intended function.
Note
The appliance is intended exclusively for domestic
use, i.e. even users who have not had any instruction
are able to operate the appliance safely.
Product information
Vitocal 060-A, type WWK
Enamelled, externally heated DHW cylinder with inte-
gral heat pump for DHW heating. A dry well heater is
integrated for DHW reheating.
Vitocal 060-A, type WWKS
Type WWKS includes the function range of type WWK.
In addition, a solar thermal system or external heat
generator (e.g. oil/gas boiler) can be connected. The
dry well heater is available as an accessory.
Operating modes
The DHW heat pump is available for recirculation air
mode, outdoor air mode and recirculation air mode
with air discharge to the outside.
Recirculation air mode
In recirculation air mode, the ambient air (indoor air) in
the installation room is used for DHW heating.
When DHW is being heated, the installation room is
cooled and dehumidified.
Recirculation air mode with air discharge to the
outside
Ambient air from the installation room is supplied to the
DHW heat pump. A separate outdoor air aperture
simultaneously allows outdoor air to enter the installa-
tion room.
The ambient air that is cooled down during DHW heat-
ing is routed outdoors by the DHW heat pump.
Outdoor air mode
Outdoor air is supplied to the DHW heat pump via a
duct.
The outdoor air that is cooled down during DHW heat-
ing is routed outdoors by the DHW heat pump.

Siting
!Please note
Impacts, compression and tensile loads can
cause damage to the outside panels of the
appliance.
Never put weight on the top or front of the appli-
ance or cylinder jacket.
The DHW heat pump can be transported vertically or
horizontally.
Note for horizontal transport
Set the DHW heat pump upright and allow it to stand
for at least 24 hours before commissioning.
Installation room requirements
■The installation room must be dry and free from the
risk of frost.
■The intake air must be kept free from dust, grease
and contamination through halogenated hydrocar-
bons (e.g. as contained in sprays, paints, solvents
and cleaning agents).
■To prevent the transmission of structure-borne noise,
never site the appliance on ceilings with wooden
joists (e.g. in the attic).
■A separately fused standard power socket must be
available.
■A condensate drain pipe must be available.
■Always maintain the minimum clearances for service
and maintenance work.
