Safety instructions for working on the system
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.
Note
In addition to the control circuit there
may be several power 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.
Prior to removing covers from the
appliances, wait at least 4 minutes
until the voltage has completely
dropped out.
■Safeguard the system against recon-
nection.
■Wear suitable personal protective
equipment when carrying out any work.

Product information
Vitocal 060-A
A DHW cylinder is integrated into the type T0E-ze
DHW heat pump.
The heat pump uses the thermal energy in the indoor
or outdoor air for DHW heating.
At times of peak DHW demand, an immersion heater
can provide reheating (fitted at the factory for type
T0E-ze; accessory for type T0S-ze).
Type T0S-ze contains the full function range of type
T0E-ze. In addition, a solar thermal system or external
heat generator (e.g. oil/gas boiler) can be connected.
The 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 temperature
(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 is supplied to the DHW heat pump. A sep-
arate outdoor air aperture simultaneously allows out-
door air to enter the room.
The ambient air that is cooled down during DHW heat-
ing is routed outdoors by the DHW heat pump.
Outdoor air mode
In outdoor air mode, outdoor air is supplied via a duct.
The outdoor air that is cooled down during DHW heat-
ing is routed outdoors by the DHW heat pump.
Outside temperature limits
Note
What DHW temperature the heat pump can achieve
depends on the outside temperature.
The maximum achieved is 62 °C.

Permissible air intake temperatures
The DHW heat pump shuts down outside the permissi-
ble air intake temperatures. In some operating pro-
grams, DHW can also be heated outside the permissi-
ble air intake temperatures, through the use of an
immersion heater (accessories). With type T0S-ze, an
external heat generator can be connected.
Permissible air intake temperatures:
■For DHW heating in recirculation air mode and recir-
culation air mode with air discharge to the outside
(temperature in the installation room):
3 °C to 35 °C.
■For DHW heating in outdoor air mode (outside tem-
perature):

Information on ductwork
!Please note
The simultaneous operation of open flue com-
bustion equipment (e.g. an open fireplace) and
the DHW heat pump in a space with combustion
air interconnection results in dangerous negative
pressure inside the room. Negative pressure
can result in flue gases re-entering the room.
■Never operate the DHW heat pump simultane-
ously with open flue combustion equipment
(e.g. an open fireplace).
■Operate combustion equipment exclusively in
room sealed mode with a separate supply of
combustion air. We recommend combustion
equipment with general building regulations
approval as room sealed combustion equip-
ment, issued by the Deutsches Institut für
Bautechnik DIBt [or local equivalent].
■Doors to boiler rooms where the combustion
air supply is not interconnected with the living
space must be airtight and must be kept shut.
Note
In recirculation air mode with air discharge to the out-
side, ensure an adequate supply of fresh air to the
installation room (on site), e.g. via separate vents (min.
DN 160).
■Thermally insulate the ductwork with vapour diffu-
sion-proof material.
■Always route the ducts for air intake and air dis-
charge with a 2 to 3° fall, so that rain and conden-
sate can drain away to the outdoors.
■Ensure air intake temperatures from -5 to 35 °C.
■Maximum permissible total pressure drop Δptotal
(ductwork and appliance): 100 Pa
■Fit silencers to prevent flow noise.
■Ducts, wall outlets and connections to the DHW heat
pump can be installed using anti-vibration insulation
to reduce noise (see diagram).
Connections and installation options which are not per-
missible:
■Connection of kitchen extractor hoods to the duct-
work
■Installation of a DHW heat pump with recirculation air
mode in a heated room
■Connection of the air intake duct to a mechanical
ventilation system
■Connection of the air intake duct to an air/geothermal
heat exchanger
■Connection of the air intake duct to a tumble dryer
■Reversed connections (air intake to the outside and
air discharge to the inside)
■Installation of the DHW heat pump in an attic
■Installation of the DHW heat pump in dusty rooms
■Operation of the DHW heat pump in conjunction with
an open flue boiler

Measures for minimising the pressure drop
■Use as few bends as possible.
■As far as possible, avoid elements that increase the
pressure drop.
■Route the air intake duct above the air discharge
duct if possible.
Positioning of air intake and air discharge aper-
tures
!Please note
An "air short circuit" will result in the cooled dis-
charged air being drawn back in to the unit. This
can result in reduced heat pump efficiency and
defrosting problems.
Position the air intake and air discharge aper-
tures so that any "air short circuit" is prevented.

Installation sequence
1. Join individual duct sections together with connec-
tion pieces or female connections (see system dia-
gram on page 15).
!Please note
Drilling swarf can cause faults in the DHW
heat pump.
Never allow drilling swarf to fall into the
DHW heat pump air intake aperture or air
discharge aperture.
2. Secure the connections with self-tapping screws or
blind rivets. Use shrink tape to make the connec-
tions airtight.
Connecting the condensate drain
When heating DHW, condensate forms on the inside of
the heat pump module. This condensate needs to be
routed via the condensate drain to a sewer.
1. Secure the condensate drain hose to the conden-
sate drain connector with a hose clip.
!Please note
Mechanical stress will damage the conden-
sate connection and may cause leaks.
Never twist the condensate drain connector
on the appliance.
2. Route the condensate hose as a U-bend and con-
nect with a constant fall and a pipe vent to the pub-
lic sewage system or a neutralising system. If nec-
essary, connect to an on-site trap. Ensure that the
trap is connected securely.
Note
Connecting the condensate drain to rainwater
downpipes is not permissible.
3. Check that the condensate can drain freely. Flush
the condensate drain if necessary.

4. Should the condensate drain run partially through
unheated rooms, provide thermal insulation or a
ribbon heater around the condensate drain on site.
!Please note
Freezing condensate in the heat pump leads
to appliance damage.
If required, fit the condensate drain with ther-
mal insulation or a ribbon heater on site.

■Non-return valve and test connector
■Pressure gauge connector
Information on drinking water filter
According to DIN 1988-2, a drinking water filter must
be installed in systems with metal pipework. We also
recommend the installation of a drinking water filter
when using plastic pipes to DIN 1988, to prevent con-
taminants entering the DHW system.
Information on the automatic thermostatic mixing
valve
The DHW heat pump can heat drinking water to above
60 °C. Therefore, an automatic thermostatic mixing
valve must be fitted in the DHW pipe to protect against
scalding.
Information on the safety valve
Install a safety assembly to DIN 1988 (DN 15 (R ¾)/
1 MPa) at the cold water connection.
If no safety assembly to DIN 1988 is installed, equip
the system with a type-tested diaphragm safety valve
as protection against excess pressure.
Installation information:
■Install the safety valve in the cold water line. Ensure
it cannot be shut off from the DHW cylinder.
■There must be no constrictions in the pipework
between the safety valve and the DHW cylinder.
■Never seal off the safety valve discharge pipe.
Ensure that any expelled water is safely and visibly
drained into a drainage system. Position a sign close
to the safety valve discharge pipe, or ideally on the
safety valve itself, with the following inscription: "For
safety reasons, water may be discharged from the
discharge pipe during heating. Never seal off."
■Install the safety valve above the top edge of the
DHW heat pump.
■Install the safety valve so it is free from the risk of
frost and connect it to an outlet pipe with a continu-
ous fall.
Technical requirements:
■Permissible temperature: 3 to 65 °C
■Permissible operating pressure: 1 to 10 bar (0.1 to
1 MPa)
