2 Safety information
Regular maintenance and cleaning
–
The boiler and the heating system components
must be maintained and checked regularly.
–
This is the prerequisite
–
for permanently reliable functioning of the boi-
ler,
–
for energy-saving and environmentally friendly
operation of the boiler,
–
for a long boiler service life.
–
Option/recommendation: Conclude maintenance
contract.
–
Documentation
is crucial: When maintenance is
performed by qualified personnel, the activities
carried out/measures taken are documented in
the maintenance log. It is advisable to keep a sys-
tem book, especially when foregoing main-
tenance by qualified personnel (for
documenting/as proof of one's own activities).
Fuel
–
The fuel used
must meet the specifications.
–
Non-approved fuel may lead to inefficient
combustion and cause damage to the boiler.
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
exchanger 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 dimen-
sioning, take material combinations into
account.
–
Repair leaks immediately.
–
Expansion tank
(prevents air from being
drawn in when the system cools down): Cor-
rectly 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 suf-
ficiently high return temperature in the boiler.
–
In the case of the
pellet
elegance
, this is ensured
by the return flow boosting which is integrated as
standard.
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 han-
dover (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 instal-
lation (in compliance with the technical docu-
mentation), we grant a warranty provided that the
system 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
usage.
–
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 mate-
rials used, but not any travel or accommodation
costs necessary for the fitters/engineers or any
return 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.
–
The company SOLARFOCUSwill determine whe-
ther such work requires a repair or whether the
parts are to be replaced free of charge.
