Indicações de segurança
Safety precautions: Before commencing mounting work on
roofs, it must be ensured in all cases that the non- personal
fall protection and fall-arrest systems required by DIN 18338
(Roof Covering and Roof Sealing Works) and DIN 18451
(Scaffolding Works) are in place. See also Builders‘ Protec-
tion Ordinance [Bauarbeiterschutzverordnung], Federal Law
Gazette 340/ 1994, paragraphs 7-10! Other country-speci c
regulations must be observed!
Safety harnesses should be  xed above the users whenever
possible. Safety harnesses should only be fastened to suf ci-
ently load-bearing structures or  xing points!
If non-personal fall protection or fall-arrest systems cannot
be installed for technical reasons, all personnel must be
secured by means of suitable safety harnesses!
Never use damaged ladders (e.g., wooden ladders with split
runners or rungs, or bent or buckled metal ladders). Never
try to repair broken runners, rungs or steps on wooden
ladders!
Only use safety harnesses (safety belts, lanyards and straps,
shock absorbers, fall arresters) that were tested and certi ed
by authorized testing bodies.
Ensure that ladders are put up safely. Observe the correct
leaning angle (68° - 75°). Prevent ladders from sliding, falling
over or sinking into the ground (e.g. using wider feet, feet
suited to the ground or hooking devices).
If non-personal fall protection or fall-arrest systems are
not provided, working without the use of suitable safety
harnesses may lead to falls from heights and therefore cause
serious or lethal injuries!
Only lean ladders against secure points. Secure ladders in
traf c areas by suitable cordoning.
Ladders not properly secured against sinking in, sliding or
falling over may lead to dangerous falls! Contact with live electric overhead cables can be lethal.
Whenever you are near live overhead electric cables where
contact is possible, only work if:
–it is ensured that they are voltage-free and this is secu-
red for the duration of work.
–the live parts are secured by covering them or cordo-
ning them off.
–the prescribed safety distances are maintained.
Voltage radius:
1 m ................voltages up to 1000V
3 m ................voltages from 1000V to 11000V
4 m ................voltages from 11000V to 22000V
5 m ................voltages from 22000V to 38000V
> 5 m in case of unknown voltages
Wear protective goggles when drilling and handling collec-
tors!

General Information
We are delighted that you have chosen our product. With this high-quality, high-performance product, you have made an
excellent selection. We wish you successful operation and many sunny days. Please read this manual carefully before installation
and commissioning, as it contains important information for proper installation and for safety.
After the commissioning has been successfully completed, the assembly instructions must be handed over to the end customer.
We would like to point out that proper function can only be guaranteed if: 1) you have annual maintenance carried out by quali-
 ed experts, 2) the instructions mentioned in this manual and 3) the stated operational recommendations are observed,
and 4) the original accessories or spare parts are used.
1.1. Expert Persons (assembly, commissioning, maintenance and troubleshooting)
"Expert persons" are exclusively those persons who are quali ed and certi cated installers (in the case of electrical components:
Electricians) with current trade registrations. All the activities listed in these installation instructions must, without exception,
be carried out by these expert persons.
1.2. General Storage and Transport Instructions
The system components must not be stored unprotected outdoors; especially the system connections and the aeration/ventilation
openings must be protected from water ingress and contamination, such as dust, etc.
The system or the storage tank must not be lifted up by the connectors or screw threads; avoid impacts and mechanical infl u-
ences on the system components, in particular on the solar glass, system back panel, pipe connections and storage tank sheath.
1.3. General Installation Instructions
Installation may only be carried out by a quali ed professional. The instructions provided here are directed at quali ed
professionals only. The supplied materials must be used for installation. Prior to installing and operating the SUNPAD system,
familiarise yourself with the locally applicable standards and regulations.
Structural Engineering Aspects
The system may only be installed on a roof surface or substructure with suf cient load-bearing capacity. The static load-bear-
ing capacity of the roof or substructure must be checked in accordance with local and regional stipulations on site prior to the
assembly of the systems. In particular, it is important to check whether the quality of the (wooden) substructure is suf cient to
ensure the durability of the screw connections for attaching the system mounting apparatus.
The on-site inspection of the system (system and attachment apparatus) as per EN 1991 and/or country-speci c regulations is
particularly important in areas prone to high winds.
When doing this, you need also to investigate all the peculiarities of the erection location (prevailing winds (foehn),
venturi effects, eddies, etc.) that may lead to locally increased load.
Information regarding inclined roofs:
The assembly of a SUNPAD system constitutes an intervention in an (existing) roof. Roof cladding such as tiles, shingles and
slate, attics with a special construction or that are used for residential purposes, and roof pitches that are below the minimum
recommended value require (in relation to the cladding) additional constructions measures to protect against the penetration
of water as a result of wind force and driving snow. This might include sub-roof membranes, for example. When selecting the
installation site, note that the maximum permissible loads due to wind forces must not be exceeded. To prevent impermissible
wind loads, the collectors must not be installed at the edge of a roof (e/10 edge zones as per EN 1991, but with a minimum gap
of 1 m). In particular, in the case of elevated structures, the top of the system must not protrude above the roof ridge.
Information regarding  at roofs:
The installation of a SUNPAD system constitutes an intervention in an (existing) roof. Attics with a special construction or that are
used for residential purposes and roof pitches that are below the minimum recommended value require (in relation to the clad-
ding) additional construction measures to protect against the penetration of water as a result of wind force and driving snow.
This might include sub-roof membranes, for example. When selecting the installation site, note that the maximum permissible
loads due to wind forces must not be exceeded. To prevent impermissible wind loads, the panels must not be installed at the
edge of a roof (e/10 edge zones as per EN 1991, but minimum gap of 1 m). In the case of larger system  elds, we recommend
that you mount the SUNPAD system on a separate bearing structure made from steel pro les.

Lightning Protection
As per the stipulations of Lightning Protection Standard EN 62305 Parts 1-4, the SUNPAD system must not be connected to the
building's lightning protection. Beyond the scope of validity of this standard, country-speci c requirements must be observed.
A safety gap of at least one metre from any adjacent conductive object must be maintained. In the case of installations on top
of existing metal substructures, an authorised and quali ed electrician must generally be consulted. To enable equipotential
bonding of the building, the metallic conductor pipes of the solar/water circuit and all of the system housing/ xtures must be
connected to the main equipotential busbar by an authorised and quali ed electrician in accordance with EN 60364 and/or
country-speci c requirements.
General Important System Information
The SUNPAD system is a two-circuit system. The SUNPAD system forms a closed circuit (process water circuit) with the heat
exchanger of the storage tank. This circuit is completely separate from the solar circuit (storage tank). The SUNPAD system or
the SUNPAD-E system offers appropriate performance only when installed in frost-free areas. If the temperature falls below 0 °C
for more than 18 consecutive hours or -5 °C for more than six consecutive hours, the domestic hot water circuit of the SUNPAD
system must be drained.
SUNPAD-E In this SUNPAD-E system, an electric immersion heater can be installed into the solar water circuit.
The system storage tank is already prepared for its installation as standard. An appropriate electric
immersion heater is available as a retro t kit in the optional scope of supply of the product.
The hot and cold water lines in the process water circuit are not protected from freezing by the elec-
tric immersion heater. When installing, appropriate insulation and trace heating for the pipes must
be provided.
The frost tolerance limits are based upon an assumed set of environmental conditions. Extended periods of cold weather,
including ambient air temperatures below the speci ed limit of -5°C, may cause freezing in exposed parts of the system. It is the
owner’s responsibility to protect the SUNPAD system in accordance with the manufacturer’s instructions if the air temperature is
anticipated to approach the speci ed frost tolerance limits.
Protect all water pipes from freezing. If the SUNPAD system is not completely drained, the warranty will become void.
After initial commissioning and in seasons with strong outside temperature fl uctuations, condensation may form in the SUNPAD
system. However, this condensation disappears after a few hours of sunlight.
A thermal mixer, where the required water temperature can be set, must always be installed at the
hot water outlet as scald protection. The safety over-pressure valve provided must be installed on
the cold water connection to the SUNPAD system in order to limit overpressure in the water circuit.
System Alignment
For the installation of the SUNPAD system, a suitable place without shade (e.g. trees, buildings) is required throughout the year.
For optimum function of the SUNPAD system, it should be installed facing south in the northern hemisphere and facing north in
the southern hemisphere, if possible. Mounting vertically to the  rst is prohibited; the system must be mounted in the horizontal
orientation. Please note the appropriate installation instructions (
see page 48).
System inclination
The SUNPAD system is suitable for an inclination of at least 5° to a maximum of 45° and may only be mounted horizontally
(+/-5°). Other installation angles are not permitted, as this will cause irreparable damage to the solar storage tank.
System pressures
The maximum operating pressure in the cold water supply must always be limited to 10 bar; if necessary, a corresponding/
suitable pressure reducer must be installed. The solar storage tank of the SUNPAD system must be kept depressurised; one of
the two  lling openings above (see sketch) must remain open due to the risk of irreparable damage to the solar storage tank.
The maximum operating overpressures speci ed on the storage tank identi cation plate must never be exceeded. The safety
valve provided must always be installed in the relevant connection on the storage tank to limit the overpressure in the process
water circuit (see sketch).

Connection Diagram:
Connections, Joints and Piping
Depending on the application, the SUNPAD system can reach temperatures of up to 95 °C, which can lead to injuries (e.g. scalding).
As a result, a suitable thermal mixer must always be installed downstream of the hot water outlet to limit the process water tem-
perature to max. 60 °C.
CAUTION: Only use pipes and  ttings that are suitable for sanitary facilities and that can
withstand temperatures of at least 100 °C.
Connections and Piping
The SUNPAD system must be connected to the connection piping (3/4
" external thread) in a fl at-sealing and only the seals
intended and provided for this purpose may be used. It is important to make sure that the fl at gaskets are properly seated.
Please pay special attention to the hydraulic diagram for the cold water and hot water connections in the manual.
When the connections are tightened up, pliers or other wrenches must be used for holding (locking), in order to prevent the
connector from being damaged. If no fl exible tubes are available for use as connection elements, make sure that the connecting
piping allows for appropriate precautions to compensate for the thermal expansion caused by temperature fl uctuations, e.g.
suitable expansion elbows or fl exible piping. In the connecting lines, tension relief must be provided (see sketch).
Insulation of the System Circuit Pipe
The pipes must be insulated with a suitable UV-resistant material to reduce heat loss and protect the pipes from freezing.
To ensure perfect functionality, make sure that the valves are not insulated. The process water connection must be established in
accordance with DIN 1988 and DIN 4753 (country-speci c regulations must be observed!).

Instructions for Commissioning and Filling the System
The SUNPAD system is delivered with a protective  lm over the solar glass. This protective  lm blocks sunlight and must not
be removed until the system has been  lled. For safety reasons (risk of burning and scalding), the  lling of the SUNPAD system
must be carried out exclusively with the protective  lm applied. This prevents heating of the solar system during installation.
Premature removal of the protective  lm could cause thermal damage to important system components due to overheating of
the product by direct sunlight. To protect the materials from excessive thermal load, the  lling and commissioning of the system
should be carried out immediately after assembly; apart from that, the system must be protected against direct sunlight.
The SUNPAD system must be  lled no later than two weeks after assembly. After initial commissioning and in seasons with
strong outside temperature fl uctuations, condensation may form in the SUNPAD system.
However, this condensation disappears after a few hours of sunlight.
Make sure that the maximum operating pressure stated on the type plate or in the installation instructions is not exceeded.
Check to make sure that all safety components have been installed in accordance with the hydraulic diagram before you open
the water supply and  ll the system before initial start-up.
Filling the System
CAUTION:
If you do not follow these instructions, the solar storage tank will be irreparably damaged!
CHECK The following procedure must be observed when  lling the system:
Connect the  lling opening of the solar circuit (solar storage tank) to the cold water pipe according to the
hydraulic diagram.
Open the cold water shut-off valve.
Fill the solar storage tank up to the water outlet on the opposite side (the storage tank is completely  lled).
Now connect the cold/hot water pipe to the SUNPAD system according to the hydraulic diagram.
Open the cold water shut-off valve to  ll the process water circuit, and then open the hot/cold tap in the house
to allow the remaining air to escape from the system.
Carefully inspect the system for leaks.
System in Unused Condition/Periods Without Hot Water Consumption
If the SUNPAD system is not used for a period of two weeks, e.g. during holidays, the SUNPAD system should remain  lled
and then be thoroughly fl ushed before  rst use (process water circuit) in order to clean possible contamination from the heat
exchanger. If the SUNPAD system is not used for a longer period of time (e.g. longer summer holidays), the system must be
covered with a light-refl ecting cloth or a light-refl ecting  lm to avoid damage caused by overheating.

Maintenance Instructions
Maintenance work may only be carried out by expert trained personnel. The SUNPAD system must be maintained and
documented at least annually in accordance with the points described (see the warranty conditions). In case of very low water
consumption or for longer periods of non-use, the maintenance interval must be shortened.
CHECK
For annual maintenance and inspection work on the SUNPAD system,
the following points must be taken into account:
Fill the water level; observe the "Filling the system" section in this manual (see page 49)
ATTENTION: If the system is operated with antifreeze, it must be re lled!
Check for damage to the system
Check for leakage on the connectors
Check for a  rm seat of the connecting screws to the roof
Check the insulation on the supply/drain line (process water circuit)
CHECK Additionally for SUNPAD-E:
Check for damage to electrical lines
Check for leaks in the e-cartridge area
ATTENTION — DANGER OF SCALDING! WARNING: WATER MAY BE DISCHARGED AT VERY HIGH
TEMPERATURES. TO AVOID SCALDING, EXERCISE MAXIMUM CAUTION WHEN DRAINING THE
HOT WATER FROM THE SUNPAD SYSTEM. DON'T TOUCH THE HOT PIPES!
To replace and maintain the electric immersion heater, ensure that the hot water temperature in the solar storage tank is not
above 45 °C. One day before the start of work, the SUNPAD system should be protected from sunlight with a cover.
We also recommended repair work be carried out only in the early morning hours.
Increasing the ef ciency
To increase the ef ciency of the SUNPAD system, observe the following recommendations:
1. If possible, use the hot water in the evening (e.g. for showering)
2. Use a timer (including overnight shutdown) in connection with the original heating element to prevent unnecessary
heat losses
3. A volume fl ow of 10 lt. / min is recommended for optimum system performance, higher fl ow rates can lead to rapid
hot water consumption.
Instructions on Using the Heating Element
(included in the scope of supply of SUNPAD-E)
Only the original heating element from the manufacturer may be used to prevent damage or destruction of the SUNPAD system.
The electric heating element is optionally available as an accessory.
Safety Instructions for Installing the Electric Immersion Heater

Maintenance of the system
The system must be inspected visually, once a year, for any damage, leaks and contamination. Condensate can form in the sys-
tem after commissioning and during times of the year with strong outdoor temperature fl uctuations. This condensate disappears
however after a few hours exposure to sunlight.
Maintenance of anti-re ective glass (AR glass)
To ensure and preserve the best possible performance of a collector with increased transmission glass (anti-refl ective glass or
AR glass for short), the following points in particular should be observed.
USE
…
•
Clean lifting gear, suction holders, and gloves
•
A cover for the glass vacuum lifter (material: Tyvek; replace when dirty)
•
Do not use the glass surface as a place to deposit installation material or other objects!
ATTENTION:
Clear the AR glass only with plain water or slightly soapy water!
The following can damage the anti-re ective coating and thus prevent the system from achieving
its full performance!
AVOID
...
•
Getting  ngerprints or stains on the glass
•
Using leather gloves
•
Contact with silicone, oil, grease, and any other thick, hydrophobic substances
•
