2.6 Intended use
The installation system is intended solely for the secure mounting of
collectors and the storage tank.
It can be used on a roof with a slope of 25 - 45°.
▶ Never modify components.
▶ Do not damage the roof or building structure.
Mount the installation system parallel to the roof, as described in these
instructions.
▶ Do not raise the installation system on-site in order to increase the
solar yields. The additional solar yields are minimal.
Permissible heat transfer medium
▶ To protect the collectors against damage through frost and corrosion,
operate them with solar heat transfer medium L
(70 % water, 30 % propylene glycol).
▶ If water is used as a heat transfer medium, the following prerequisites
must be fulfilled:
– Continuous ambient temperatures above 5 °C.
– Closed circuit. This prevents the introduction of oxygen. In the
event of a pressure drop, remedy the fault immediately.
– Have the water checked ( table).

Permissible loads
▶ Only install collectors in locations with values lower than those shown
in the following. If required, consult a structural engineer.
Table 12 Maximum loads for the installation set
(with reference to DIN EN 1991, parts 3 and 4)
When determining the maximum wind speed, take the following factors
into account:
• Location of the thermal solar system
• Geographical height of the terrain
• Topography (terrain/buildings)
• Height of building
The maximum snow load is calculated using regional zones (snow load
zones) and the ground level elevation.
▶ Enquire about the locally applicable snow loads
( e.g. technical guide).
Permissible roof connections
▶ Collectors: use roof hooks or double-ended screws.
▶ Storage tanks: only double-ended screws are permissible.
▶ Only screw double ended screws into a substructure with sufficient
load bearing capacity.
Corrosion protection
All supplied components are protected against corrosion through either
the material (e.g. aluminium, plastic) or coatings.
▶ Only use materials on site that can withstand local weather
conditions.
The potable water area in the storage tank is protected against corrosion
through enamel coating and a magnesium anode. To maintain this
protection:
▶ Observe the maintenance intervals and instructions in the
"Maintenance, inspection" section.
2.7 Recommendations for energy savings
▶ Install the DHW mixing valve as close as possible to the storage tank
( section "Hydraulic connection" for system examples).
▶ When using an immersion heater:
– Only connect the immersion heater to the mains power supply
when insufficient solar exposure is expected (e.g. during winter,
at night).
– Disconnect the immersion heater from the mains power supply
when solar exposure is sufficient or during absences (e.g.
holidays).
– Use a timer or similar to ensure appropriate use of the immersion
heater.
– Set the temperature as low as possible.
▶ To be able to use as much solar-heated water as possible, draw hot
water only after the sun has peaked (midday).
▶ Connect dishwashers and washing machines (if suitable) to the DHW
pipe and where possible use these between 15:00 and 18:00.
▶ Position the thermosiphon system so that the DHW pipe is as short as
possible. Ensure the DHW pipe is very well insulated.
