Injury due to moving parts
►
Switch device on only with air ducts and weather
and/or rain louvres fitted.
Injuries and environmental damage due to
refrigerant
The unit contains harmful and environmentally
dangerous refrigerant. If refrigerant leaks from the unit:
1.
Switch off unit.
2. Thoroughly ventilate installation area.
3. Notify authorised after sales service.
2.5 Disposal
Media harmful to the environment
Improper disposal of environmentally harmful media
(refrigerant) damages the environment:
►
Collect media safely.
►
Dispose of the media in an environmentally
compatible way in accordance with the local
regulations.
2.6 Avoid damage to property
The ambient air at the heat pump installation site, as
well as the air drawn in as a heat source, must not
contain any corrosive constituents!
Constituents such as
●
Ammonia
●
Sulphur
●
Chlorine
●
Salt
● Sewer gasses, flue gasses
can cause damage to the heat pump, which could lead
to the complete failure / destruction of the heat pump!
Decommissioning/emptying heating
If the system / heat pump is decommissioned or
emptied, after it has been filled already, it is necessary
to ensure that the condenser and any heat exchangers
present have been completely emptied in the event
of frost. Residual water in heat exchangers and
condensers can result in damage to components.
►
Empty system and condenser completely, open
vent valves.
►
Blast out with compressed air if necessary.
Improper action
Requirements for minimum scale and corrosion
damage in hot water heating systems:
●
Proper planning, design and commissioning
●
Closed system with regard to corrosion
●
Integration of an adequately dimensioned
pressure maintaining device
●
Use of demineralised heating water (VE water) or
water corresponding to the VDI 2035 norm
●
Regular servicing and maintenance
If a system is not planned, designed, started up and
operated in accordance with the given requirements,
there is a risk that the following damage and faults will
occur:
●
Malfunctions and the failure of components, e.g.
pumps, valves
●
Internal and external leaks, e.g. from heat
exchangers
●
Cross-section reduction and blockages in
components, e.g. heat exchanger, pipes, pumps
●
Material fatigue
●
Gas bubbles and gas cushion formation
(cavitation)
● Negative effect on heat transfer, e.g. formation of
coatings, deposits, and associated noises, e.g.
boiling noises, flow noises
►
Note and follow the information in this operating
manual for all work on and with the unit.
Unsuitable quality of the fill and make-up
water in the heating circuit
The efficiency of the system and the life of the heat
generator and the heating components depend
decisively on the quality of the heating water.
If the system is filled with untreated drinking water,
calcium precipitates as scale. Limescale deposits
form on the heat transfer surfaces of the heating. The
efficiency drops and energy costs rise. In extreme
cases the heat exchangers are damaged.
►
Fill the system with deionised heating water
(VE water) or with water corresponding to the VDI
2035 norm only (low-salt operation of the system).
