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 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'.
■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 replacements, use only original spare parts
supplied or approved by Viessmann.

Intended use
The appliance is only intended to be installed and
operated in sealed systems or solar thermal systems
that comply with EN 12976 and EN 12977, with due
attention paid to the associated installation, service
and operating instructions. DHW cylinders are only
designed to store and heat water of potable water
quality. Only operate the solar collectors with heat
transfer medium approved by the manufacturer.
Intended use presupposes that a fixed installation in
conjunction with permissible, system-specific compo-
nents has been carried out.
Commercial or industrial usage for purposes other
than heating a building or DHW shall be deemed inap-
propriate.
Any usage beyond this must be individually approved
by the manufacturer.
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 applies 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.

The thermosiphon solar thermal system consists of a
flat-plate collector with highly selective coating and an
enamelled DHW cylinder for DHW heating. A magne-
sium anode and an immersion heater are fitted in the
DHW cylinder.
The Vitosol 111-T can be installed on flat roofs and
pitched roofs.
The fixing systems for flat roof installation are available
for installation angles 15°, 30° and 45°.

■Has the safety valve (T&P valve) been installed?
■Has the hot water drain been installed so that any
discharged hot water or steam cannot present a risk
to individuals?
■Has the hot water drain been installed so that any
discharged hot water or steam cannot damage the
system and materials in or on the building?
■Has an automatic thermostatic mixing valve for limit-
ing the temperature to 60 °C been installed?
Filling the DHW cylinder on the DHW side
1. Fill the DHW cylinder on the DHW side.
Note
If the DHW cylinder is pressurised, retighten the
flange cover with a torque of 25 Nm.
2. Check the fittings on the DHW side and the immer-
sion heater for leaks. If required retighten fittings.
3. Check the function of the safety valves according
to the manufacturer's instructions.
Filling the DHW cylinder on the solar side
Fig. 4
1. Remove the closure on the container with heat
transfer medium and replace with the closure sup-
plied.
2. Make the hose connection between fill valve B on
the DHW cylinder and the container with heat
transfer medium.
3. Position the canister above the DHW cylinder.
4. Open fill valve B.
5. Vent the following while filling:
■DHW cylinder at air vent valve C
■Collectors at air vent valve A
Inspection and maintenance
When carrying out maintenance work, cover the col-
lector to protect the components from thermal loads.
DIN 1988 requires a visual inspection and (if neces-
sary) cleaning of the DHW cylinder no later than 2
years after commissioning, and thereafter according to
requirements.
Note
We additionally recommend that the function of the
magnesium anode is checked annually. For removing
the magnesium anode, see page 10.
Shutting down the system
Cover the collectors. Switch OFF the immersion heater
and safeguard against reconnection.

Cleaning the inside of the DHW cylinder
8x
2x
Fig. 5
AImmersion heater
BMagnesium anode
1. Drain the DHW cylinder on the DHW side.
2. Open the DHW cylinder.
3. To prevent cleaning agents and contaminants
entering the pipework, separate the DHW cylinder
from the pipework.
4. Remove loose deposits with a high pressure
cleaner.
!Please note
Pointed or sharp cleaning tools will damage
the cylinder interior.
Only use plastic tools to clean the inside.
5. Use a chemical cleaning agent to remove hard
deposits that cannot be removed with a high pres-
sure cleaner.
!Please note
Cleaning agents containing hydrochloric acid
will attack the DHW cylinder material.
Never use such cleaning agents.
Danger
Cleaning agent residues can result in poi-
soning.
Always observe the information provided by
the cleaning agent manufacturer.
6. Fully drain all cleaning agent.
7. Flush the DHW cylinder thoroughly after cleaning.
Checking and replacing the magnesium anode (if required)
Check magnesium anode B. See Fig. 5.
We recommend replacing the magnesium anode if the
7 of the anode is ≤ 10 to 15 mm.
