GENERAL SAFETY RULES
WORK AREA (Especially when working on the roof)
» Keep the work area clean and well organized.
» Keep bystanders, children and visitors away from the work area while installing this product. Distractions can
cause one to lose control and personal injury can occur.
» Be aware of, and avoid, any power lines that may be in the vicinity. Avoid using a metal ladder near power lines
or exposed energized electrical equipment.
» Always wear slip resistant (e.g., rubber-soled) shoes that have sufficient traction on the soles.
» When working on a ladder, try to achieve three points of contact whenever possible.
» If you need to get tools or supplies onto the rooftop, consider how you will get them up and down safely. Always
work with at least one assistant.
» Ensure that anything placed on the roof cannot fall off and hurt someone. If there is no way to completely and
safely secure material that is resting on the roof, then make sure that the ground area is cleared of all people.
» Get down off of the roof or ladder before you engage in activities that will divert your attention. Use your com
mon sense. Do not talk on your cell phone, eat, drink, or chat unnecessarily while you are on the rooftop or ladder.
» If it is windy or rainy, delay the project. Working at height with wet ladder steps and on slick surfaces invites un
necessary danger.
» Never work on the roof when lightning threatens.
» Even after the rain stops, avoid working on roofing projects. The ground may be muddy or saturated, and wet
ground conditions can lead to the ladder slipping or sinking.
» If you have balance problems or health risks, such as seizures or fainting spells, that increase the dangers of
working at height, contact a friend or a professional to complete this part of your project.
Personal Safety
» ALWAYS wear eye protection to avoid injury to the eyes while using hand or power tools.
» Wear heat resistant and puncture resistant gloves while handling evacuated tubes or working around
potentially hot pipes or fittings.
» Do not wear loose fitting clothing or jewelry that may get caught in power tools.
» Installers working below a roof installation should wear an impact resistant hard hat to avoid injury from falling
objects.
» On a steeply pitched roof, be sure to wear a safety harness that is securely tied off to a fall arresting device.
ALTERATIONS AND CHANGES APART FROM THOSE DESCRIBED IN
THE INSTRUCTION MANUAL ARE NOT ALLOWED.

Installation Safety
» Always consult local and state building codes and other applicable standards and regulations before begin-
ning a solar collector installation.
» Adhere to all applicable codes and standards during installation. Special consideration must be given to build-
ing code requirements for the penetration of structural members and fire rated assemblies.
» Ensure that the mounting surface to which the collector(s) will be attached are structurally sound and capable
of supporting the load of the collector(s).
» Read and follow all labels/markings on the ladder. Always inspect the ladder prior
to using it. If the ladder is damaged, it must be removed from service and tagged
until repaired or discarded.
» Do not use the top step/rung of a ladder as a step/rung unless it was designed for
that purpose
» Only use ladders and appropriate accessories (ladder levelers, jacks or hooks) for
their designed purposes.
» An extension or straight ladder used to access an elevated surface must extend at
least 3 feet above the point of support (see diagram). Do not stand on the three top
rungs of a straight, single or extension ladder.
» The proper angle for setting up a ladder is to place its base a quarter of the work-
ing length of the ladder from the wall or other vertical surface (see diagram).
» Be sure that all locks on an extension ladder are properly engaged.
» Do not exceed the maximum load rating of a ladder. Be aware of the ladder’s load
rating and of the weight it is supporting, including the weight of any tools or equipment.
» A ladder placed in any location where it can be displaced by other work activities must be secured to prevent
displacement or a barricade must be erected to keep traffic away from the ladder.

PRODUCT & SAFETY RISKS
This product has been manufactured to provide the highest level of performance and reliability. Nevertheless,
there can still be risks associated with installing, using and maintaining this product.
Dangers can arise from
» Components of the collector become very hot during operation (will burn when touched)
» Other risks may originate from broken glass (cut injury)
» Spurting hot fluid and flowing steam (scalding injury)
» Falling when working on the roof
The Stiebel Eltron S-Power Performance Series HP evacuated-tube solar collector must be installed and put into
operation in accordance with this instruction manual. It must be used exclusively for the described purpose. If used
other than the described purpose (abusive use), dangers for persons can arise and the collector can be damaged.
Misuse of this product can be, for example, filling the collector with other substances than an appropriate heat
transfer medium or the installation on surfaces that are not sufficiently stable.
ALTERATIONS AND CHANGES APART FROM THOSE DESCRIBED IN
THE INSTRUCTION MANUAL ARE NOT ALLOWED.
05

06
The Stiebel Eltron S-Power Performance Series HP evacuated-tube solar collector must be mounted and operated
according to theapproved safety rules and technical regulations, of each locale. During assembly, workers must
adhere to the respective national regulations for employee protection (e.g. OSHA) and accident prevention. This is
especially important when working on the roof.
Lightning Protection
NOTICE
All electrical equipment with a metal housing must be grounded. This also applies to solar-thermal
systems. The pump set, pipes, reservoirs and collectors must be provided with a ground connec-
tion, i.e., be connected to earth just like any standard water pipe. Grounding requires a secure con-
ductive contact between the ground point and the collector. The grounding clips can be installed to
the collector frame. The solar circuit pipeline system has to be connected to the building’s ground
over short runs for both the feed and the return lines.
Handling Glass Tubes
WARNING
!
The glass tubes have a vacuum. Damage due to external pressure, loading or twisting, application
of concentrated loads or force impact may cause implosion. Flying glass fragments may cause in-
juries. Only a certified heating contractor or North American Board of Certified Energy Practioners
(NABCEP) certified solar thermal installer should carry out dismantling and disposal. All materials
used are recyclable.
Maintenance
The maintenance of solar systems must be done by licensed heating contractors and relates mainly to the heat
transfer medium. The collectors undergo a visual inspection only. They have to be replaced if damaged or if the
tubes experience a loss of vacuum.
Single tubes may be replaced on-site.
Due to the nano coating on the vacuum tubes, the collector is self-cleaning. If, however, the tubes become dirty,
the collector may be cleaned with water.
DO NOT USE INDUSTRIAL CLEANERS OR ABRASIVE CLEANERS!

Risk of Burning
WARNING
!
»The metal parts of the collector can become very hot when exposed to the sun even on cloudy days and
can cause burns when touched! Do not leave a collector unprotected to the sunlight after unpacking it. Install
the roof assembly on a cloudy day and preferably not at noontime or shade the collector with a light blocking
material.
»TAKE THE COLLECTOR OUT OF THE BOX ONLY AFTER ALL FASTENING ELEMENTS ARE
ALREADY INSTALLED ON THE ROOF. If you install multiple panels, remove only one set of collector tubes
from the box and assemble one complete collector before you unpack the next.
»After a collector is completely installed and exposed to sunlight the risk of burns from hot metal parts is in-
creased. Use caution when working around the collector and use heat protective gloves when handling metal
pipes and connectors associated with the collector.
Personal Risk of Falling
WARNING
!
When working on the roof or climbing up or down ladders or scaffolding there is danger of falling. Please con-
sider the accident prevention regulations (e.g. OSHA) and use appropriate safeguards.
Personal Risk of Falling Objects
WARNING
!
During installations on the roof, there is a danger that tools, assembly equipment or the collector can fall from
the roof and injure persons standing below. Barricade off the danger area on the ground before the start of as-
sembly work and warn persons who are nearby to stay out of the work zone.
Make sure that children and bystanders are kept away.
Unauthorized persons are not allowed to climb onto the roof.
WARNING
!
If the collector is installed on a roof that is not suitable for the installation, the collector can become loosened.
This could lead to damage to the collector and the roof or, if the collector falls from the roof, injuries to some-
one. Therefore, the collector must only be installed on roofs where it can be properly attached.
Handling Glass Tubes
WARNING
!
The glass tubes have a vacuum. Damage due to external pressure, loading or twisting, application of concen-
trated loads or force impact may cause implosion. Flying glass fragments can cause injuries.

tion and/or certification.
WHO IS ALLOWED TO INSTALL
SOLAR COLLECTORS?
The following aspects should be considered when planning a system:
What energy will be consumed in what period of time?
Will demand/consumption be continuous (weekends, vacation periods)?
How much energy will need to be stored so that there is enough usable energy when solar radiation is not available?
Will there be any alternative uses such as pool heating, solar cooling, geothermal processes, radiant heating or similar?
What is the current feed/return temperature of the heating system?
What is the planned orientation of the collector panels, and assembly options?
Determine the length, diameter and compositions of pipe(s).
