and disposal
For
− Installation,
− Commissioning and
− Maintenance
of the boiler: this may be performed by qualified and trained personnel
only. In accordance with VDE 0105 Part 1, work on electrical components
(e.g. control unit) may only be carried out by qualified electricians.
VDE/ÖVE regulations [Germany/Austria] and those of your local power
supply utility company are applicable to electrical installation work.
Only operate the boiler within its output range, which is stated in the
technical documentation supplied by WOLF. Appropriate use of the
boiler refers to the exclusive use for hot water heating systems in
accordance with EN 12828. Never remove, bypass or otherwise disable
any safety or monitoring equipment. The boiler must only be operated
if it is in perfect working order. Any faults or damage which impact
or might impact safety must be remedied immediately by a qualified
contractor. Only replace faulty components and equipment with original
WOLF spare parts.
Never touch electrical components or contacts when the ON/OFF switch
is in the ON position. There is a danger of electrocution, resulting in a
risk to health or death. The main terminals are 'live', even when the ON/
OFF switch is in the OFF position.
Before removing the casing
- I solate the system from the power supply (e.g. by removing the
separate mains fuse or by means of a mains electrical isolator or
heating emergency stop switch) and check to ensure that there is no
voltage.
- Safeguard the system against reconnection.
Devices with insufficient combustion air supply or flue gas removal
may cause flue gas to leak into the installation room. This results in a
risk of asphyxiation, or severe to life-threatening poisoning.
- Switch OFF the appliance if you smell flue gas
- Open windows and doors
- Notify an approved contractor
Oil condensing boilers include oil-bearing parts. This is a risk to
health from drinking water contaminated with oil.
- Lock the oil supply to oil-bearing parts before starting any work.
- P erform a seal inspection on oil-bearing parts after work has
finished
Boilers may contain hot water.
Hot water can cause severe scalding.
Before working on parts which are in contact with water, allow the
appliance to cool to below 40 °C, shut off all valves and, if necessary,
drain the appliance.
Boiler components may be extremely hot.
Hot components can cause burns.
Before working on the opened up appliance, allow it to cool below
40 °C or wear suitable gloves.
Boilers are subject to high water pressure.
Water pressure can cause severe injuries.
Before working on parts which are in contact with water, allow the
appliance to cool to below 40 °C, shut off all valves and, if necessary,
drain the appliance.
Note: S ensors can be in contact with water and therefore exposed to
pressure.
