plus
Specifications for the heating system's fill-
up/make-up water
- Check pH value: this must be in the range of
8.2 to 9.5
- Avoiding scale buildup (=limescale on heat ex-
changer surfaces):
- Take the water hardness into account
- Soften the fill-up water, or better: desalinate it.
- Avoiding water-side corrosion (is triggered by the
oxygen in the water):
- Correct system planning, correct dimensioning,
take material combinations into account.
- Repair leaks immediately.
- Expansion tank (prevents air suction when the
system cools down): Correctly set the pressure,
check it regularly.
- Existing underfloor heating: Take care with old,
diffusion-open plastic pipes.
Return temperature in the boiler
- A temperature below the dew point (leads to cor-
rosion in the boiler) must be prevented by a suffi-
ciently high return temperature in the boiler.
- Due to the integrated design of the octo
plus
, return
flow boosting is not required.
Supply air to the heating boiler
- The supply air in the boiler must not contain any
aggressive substances. These substances can
cause corrosion in the boiler and chimney.
- Aggressive substances are, for example, chlorine
or fluorine compounds (used in cleaning agents,
solvents, adhesives, etc.).
3.1.2 Conditions for claims
For warranty and guarantee claims observe the fol-
lowing points:
- The warranty begins at the time at the time of
handover (delivery note, commissioning log).
- The warranty period is calculated from the date of
initial commissioning (according to the control's
operating hour counter).
- The warranty periods are based on the relevant
regulations.
- We must be notified promptly and accurately of
any damage incurred, so that the cause can be
clarified.
- If the system has defects despite correct installa-
tion (in compliance with the technical documenta-
tion), we grant a warranty provided that the sys-
tem has been examined by the plant customer
service (commissioning log).
- The guarantee applies to technical, construction-
related faults and faults in the manufacture of the
system that prevent correct and problem-free us-
age.
- We are not liable for parts that were not produced
by SOLARFOCUS. However, we are prepared to
transfer our existing claims against the producer
(relating to this defect) to the buyer.
- In fulfilling the warranty/guarantee services, we
shall cover only the assembly time and the materi-
als used, but not any travel or accommodation
costs necessary for the fitters/engineers or any re-
turn transport costs.
- SOLARFOCUS GmbH assumes no liability for
any consequential costs of damages.
- The repair and/or warranty replacement shall be
carried out on site or in the SOLARFOCUS fac-
tory at our discretion.
- SOLARFOCUS will determine whether such work
requires a repair or whether the parts are to be re-
placed free of charge.
3.1.3 Claims rendered void
The warranty and guarantee claims are rendered
void if one of the following points applies:
- Non-compliance with the technical requirements


- Damage during transport.
- Wilful damage.
- Damage due to force majeure (water, fire, etc.).
- Non-observance of information in the planning, in-
stallation and operation manual.
- Insufficient energy or water, fault in the hydraulics.
- Incorrect operation, failure to perform mainte-
nance and cleaning as prescribed.
- Commissioning and maintenance carried out by
non-certified companies.
- Undocumented commissioning (no commission-
ing log) and/or maintenance (maintenance log).
- It is almost impossible to produce flawless painted
parts; for this reason, slight defects that do not ad-
versely affect proper use shall not be deemed as
grounds for complaint.
- No claims can be accepted under the warranty if
unauthorised intervention (or action that has not
been explicitly approved by us the manufacturer)
has been carried out. In addition, the goods must
be paid for within the specified payment
timeframe.
