Documentation for the contractor
Please read carefully prior
to installation and maintenance
When the anode rod is not professionally and annually maintained, the
tank will lose its warranty. Annual
service records must be maintained
and shown in case of a warranty
claim along with an original proof of
purchase. Refer to page 23 to 27 for
annual maintenance instructions to
maintain tank warranty.
In the Commonwealth of Massachusetts this tank must be installed by a
licensed plumber.

Safety Precautions and symbol clarification
1 Safety Precautions and symbol clarification
1
1.1 Placement, remodeling
Placement, remodeling
V Fire danger!
Solder and welding operations can result in fire, as the
insulation is combustible.
V The solar tank can only be installed or renovated by
technical specialists.
Installation and Start-up Procedure
V In the Commonwealth of Massachusetts this tank must
be installed by a licensed plumber.
V Any electrical wiring must be installed by a licensed
electrician.
V Do not assemble the equipment in a damp environ-
ment.
Function
V Follow these directions for trouble free operation for
installation and maintenance.
V Danger of Scalding!
(> 140 °F) during operation of the tank as part of a
solar system. Please install tempering valve on domestic hot outlet connection of tank, which is supplied with
solar pumping station
Maintenance
V Recommendation for end customer: Please sign
up for an annual service and maintenance contract with
your installer. Make sure to have annual maintenance
performed on your boiler and solar system.
V Use only original replacement parts.
1.2 Symbol Clarification
Safety warnings are designated in the text
with a triangular warning label and grey coloring.
Signal words are describing the gravity of each danger
when safety precautions are not followed.
– Careful indicates possibility of light property damage.
– Warning indicates light personal injury or severe prop-
erty damage.
– Danger indicates possible severe personal injury with
potential loss of life.
Guidelines in the text are designated with
shown symbol. The text is bracketed between
two horizontal lines.
Guidelines contain important information in these cases
to avoid or reduce danger to people and equipment.
In case the solar storage tank will be installed in Massachusetts, it must be installed by an installer or dealer who
is registered in that state.
We reserve the right to change and improve technical
information without notice.
It is expected that the installer is a licensed heating contractor with the knowledge of accepted industry practices
for the installation and maintenance of the equipment and
various applications of the equipment involved.

2.1 Applications
The solar tanks SM300/1 and SM400/1 are designed for
the heating and storage of domestic hot water. Applicable
guidelines for domestic hot water must be followed.
2.2 Intended Use
The domestic hot water can be heating by a solar system
with a boiler as a back-up system, or by a boiler in general
for high output hot water heating. (Operate the 2 coils
either in series or in parallel). In case of solar heating, the
solar system must be filled with a solar fluid to prevent
accidental freezing. The tank can only be used in a closed
system.
Any other application voids the warranty of the tank.
2.3 Guidelines for Installations
Follow all specific state and local codes regarding the installation and operation of the
equipment.
All electrical components must be approved
for the US.
2.4 Product Disposal
V Dispose of packaging of the solar tank in an environ-
mental friendly fashion.
V A solar hot water heater that is being replaced must be
disposed of in a suitable fashion.

2.5 Product Packaging
Solar hot water tank consists of:
– Tank shell [6] with corrosion protection and magne-
sium anode rodes.
– Tank insulation [1] made from non FCKW insulation
material.
– SM300/1: direct attached to tank shell.
– SM400/1: Insulation must separately be installed.
– 2 Smooth high output heat transfer coils [11]
– The smooth surface coil transfers the energy from
the solar and/or heating system to the domestic
water inside the tank shell. The water volume is
evenly heated with the coil areas.
– Dry well M1 [12] for installation of DHW tank tempera-
ture sensor or aquastat.

3.1 Transportation Means
One can move the solar water heater tank SM300/1 with
a hand dolly and the SM400/1 also with a lifting crane or
device.
Danger: Potential danger due to falling over
of tank.
V Use only transport devices that are in safe
operating condition
V Place the lifting hook only in the designat-
ed location.
Danger: Potential for injury due to carrying
of heavy loads.
V Also move and lift the tank with at least
two people.
Caution: Potential damage due to improper
securing of tank for transport.
V Use suitable tools and strapping materials
when securing and moving the tank with a
transport aid.
Bring in the entire tank in its original packaging to the final installation location. This will
protect the tank better during transport.
A Buderus dolly (kuli cart) can be purchased
through your local wholesaler.
3.1.1 Transportation with dolly
V Place the hand dolly at the backside of the packaged
tank.
V Strap the tank to the hand dolly.
V Move the tank to its final location.
V Remove only the tank packaging at the final installation
site.

3.1.2 Transportation with overhead crane
V Place the two lifting hooks of the chain into the desig-
nated lifting rings on top of the tank [1].
V Hook the crane chain into the lifting chain.
V Protect the tank from falling and lift the tank to its final
installation location.
V Lower the tank carefully to the floor; do not drop down
onto the floor!
One can move the tank inside the building also in a horizontal manner due to possible height restrictions.
V Remove only the tank packaging at the final installation
site.

3.2 Product Placement
Caution: Damage due to internal stresses
and corrosion!
V Place the tank in a frost free room.
V Use the solar water heater ONLY in
closed loop applications.
V Open expansion tanks can NOT be used
with these solar water heater tanks.
Minimum 12" overhead space is required for
the removal of the magnesium anode rod as
well as some side clearance.
V Verify for suitable clearance dimensions by
referencing (Æ Tab. 1, page 9 und Fig. 7).
V Maintain suggested service access dimensions
(Æ Fig. 7).
V Maintain 2" clearance from heated pipes to
combustible surfaces.
V Place tank on a level and sufficiently strong floor.
V Remove plastic and packaging materials.

4.1.1 Installation of tank feet
V Place top foam material on the floor [1].
V Carefully place the solar tank on its side on top of the
foam material.
V Remove the tank support bolts M10x30 from the Styro-
foam packaging and screw into the bottom of the tank
[2].
V Put solar tank straight-up and level by adjusting the
tank bolts [2].

4.1.2 Installation of tank aquastat or temperature
sensor
Danger: Risk of fatal injury from electric
shock.
V Electrically disconnect the system.
For DHW temperature control, one can
use an aquastat or tank sensor depending
on the selected control strategy.
Follow the directions supplied by the manufacturer of the aquastat or tank sensor regarding electrical wiring connections and
temperature adjustments.
V To measure and secure the DHW water temperature
an installed temperature sensor or aquastat on the
DHW tank is reqiured.
