2. SAFETY INSTRUCTIONS
General Information
Read this entire manual. Failure to follow all the guides,
instructions and rules could cause personal injury or property
damage. Improper installation, adjustment, alteration, service and
use of this unit can result in serious injury.
This unit must be installed by a professional installer. The
installation must comply with all national, state and local plumbing
and electric codes. Proper installation is the responsibility of the
installer. Failure to comply with the installation and operating
instructions or improper use voids the warranty.
Save these instructions for future reference. Installer should leave
these instructions with the consumer.
Service of the unit must be performed by a qualified service agency.
Never set the solar loop pressure greater than potable (domestic)
water supply pressure. If the potable water pressure is too low, a
booster pump may be needed to assure that it exceeds the required
solar loop pressure.
If you have any questions regarding the installation, use or
operation of this water heater, or if you need any additional
installation manuals, please call our technical service line at 800-
582-8423 (USA and Canada only). If you are calling from outside
the USA or Canada, please call USA 413-247-3380 and we will refer
you to a qualified Stiebel Eltron service representative in your area.
This is the safety alert symbol. It is used to alert you to
potential personal injury hazard. Obey all safety messages
that follow this symbol to avoid possible injury or death.
Safety Instructions
WARNING: Never install any valves or shutoff devices in the
piping between the collectors and the safety valve. The
safety valve is actuated at 87 psi pressure.
DANGER: Water temperatures over 125 °F can cause
severe burns instantly or death from scalding. A hot
water scalding potential exists if the thermostat on the unit is
set too high. Households with small children, disabled or elderly
persons may require that the thermostat be set at 120 °F or lower
to prevent possible injury from hot water.
DANGER: Setting the maximum tank temperature higher
than 140 °F at the control unit is permissible only in
conjunction with a thermostatically-controlled DHW mixing valve.
Otherwise there can be a risk of scalding at the drawoff point.
CAUTION: All sensor wiring should be rated for expected
temperatures and must be protected from degradation and
electrical interference.
Solar Loop
Use only a mixture of 50% GRAS (food grade) Propylene Glycol and
de-ionized water. (Heat Exchanger type SW, AWWA Fluid Class II -
see MSDS for handling instructions.)
WARNING: Fluid may be discharged at high temperature
and/or pressure. THere can be a risk of scalding at the
discharge point.
No other fluid shall be used that would change the original
classification of this system. Unauthorized alterations to this
system could result in a hazardous condition.

3.1 Start-up
The hydronic back-up boiler (see Figure 5) and solar
storage tank (see Figures 4 & 5), constitute a functional unit. Hot
water is generated throughout the year by the solar collectors (see
Figure 4). Supplemental heat is provided by the back-up boiler
when there is insufficient solar energy available (see Figure 5).
The entire heater and hot water system must be filled with
water and have adaquate air ventilation. Please refer to the solar
collector’s and the boiler’s installation instructions.
3. OPERATION AND SERVICE
4. MAINTENANCE AND CLEANING
Routine care and maintenance extends the life expectancy and
operating safety of the hot water storage unit. The outer casing
should be cleaned with a slightly damp cloth and commercially
available neutral cleaning agent. This should be done on a regular
basis.
4.1 Temperature / Pressure Relief Valve
WARNING: The T&P relief valve is designed to relieve built
up pressure in the water heater. Fluid may be discharged
at high temperature and/or pressure. Scalding hot water injuries
can occur.
Notice: The water heater and T&P relief valve should be installed
and piped in and to an area where water discharge and leaking
will not cause property damage.
The proper function of the Temperature / Pressure (“T&P”) relief
valve is required to prevent damage to the hot water storage unit.
The T&P valve needs to be open during cold-water addition. The
water has to flow from the relief line at full stream.
4.2 Decalcification
With hard tap water, a deposit of scale will form on the inside of the
storage unit. Based on professional experience, it is necessary to
decalcify with commercially available solvents at timely intervals.
Follow the manufacturers instructions for solvent use. The hot
water storage unit needs to be emptied. The inspection cover must
be removed and sediments on the tank bottom must be flushed.
4.3 Replacement of the Sacrificial Anode
Depending on the composition of the tap water, an inspection
of the sacrificial anode (Pos. 1, Figure 1) at timely intervals
is recommended. With heavy wear, an original equipment
replacement anode must be installed to protect the inner container
from corrosion. An inspection should be performed at least once a
year.

regulator, see Figures 4 & 5). The order of the individual fittings must
be in accordance to local regulations.
8.4.4 Pressure Regulator Settings
The pressure regulator has to be set to 150 psi (10 bar). It can
only be installed into the cold water supply. The supply has to be
thoroughly inspected prior to installation. Installation of dirt filters
or any other narrowing of the supply line to the pressure relief valve
is forbidden.
The temperature & pressure relief valve has to be easily accessible.
Expansion water generated during the heating has to flow visibly to
a drain. The drainage pipe must be large enough to accommodate
water drainage with a fully opened T & P valve. The drainage pipe
must be protected from freezing and must not lead outdoors.
The pressure regulator (Figures 4 & 5) has to be set so no water
drips from the T & P valve.
Heavy dripping of the T & P valve can be caused by dirt in the valve
seat or water pressure. Water pressure needs to re regulated below
150 psi.
8.4.5 Before Filling
Prior to filling all screws must be tight.
8.4.6 Drainage and Re-circulation
Drainage of the hot water tank is via the fill & drain valve (Figures 4
& 5).
A re-circulator can be attached to a separate socket across the
thermometer. Drill the outer casing with a hole saw
Ø
50 where
marked and remove insulation from the socket in that area.
For energy conservation, use of a circulator is not recommended.

tion instructions for the SOL 25 Plus flat plate solar collector.
IMPORTANT NOTICE: Test operation after installation. Start up must follow
the approval of the installer (refer to section 3. operation and service).
8.8 Sacrificial anode (spare part)
If a sacrificial anode is installed into the SBB S or SBB Plus storage
tank, the following must be observed:
Installation – sacrificial anode
• Pull out the red shut-off plug while simultaneously depressing the
pressure ring, (see Figure 7).
• Push in the open pipe end of the indicator element until dead-
stop.
• Attach the sticker “Note Signal Anode” to a highly visible spot on
the insulation.
NOTICE: When the storage tank is not operated with a signal display, the
red plug must remain in the anode.
Function – Sacrificial indicator
• After consumption of the anode, humidity escapes through the
hollow anode core to the signal cartridge and causes a color
change there (see Figure 7)
• When the cartridge turns red contact the installer so he can check
the anode and if needed replace it.
Routine maintenance improves operating safety and life
expectancy of the SBB S and SBB Plus solar hot water
storage tanks.
