2.4 Residual risks
Injuries caused by electric shock
Components in the unit are energised with life-threat-
ening voltage. Before working on the unit:
►
Disconnect unit from power supply.
►
Protect unit against being switched back on again.
►
Wait 2 minutes before opening the unit, due to the
residual voltage at the inverter
Existing earthing connections within housings or on
mounting plates must not be changed. If this should
nonetheless be necessary in the course of repair or in-
stallation:
►
Restore earthing connections to their original
state once repair or installation is complete.
Injuries caused by moving parts
►
Only switch on the unit once outer panels and fan
protective grilles have been fitted.
Injuries caused by high temperatures
►
Before working on the unit, let it cool down.
Injuries and environmental damage due to
refrigerant
The unit contains refrigerant that is hazardous to
health and the environment. If refrigerant leaks from
the unit:
1. Switch off unit.
2. Notify authorised customer service.
Safety labels
►
Observe safety labels on and in the unit.
2.5 Disposal
Environmentally harmful media
Improper disposal of environmentally harmful media
((primary) refrigerant) damages the environment:
►
Collect media safely.
►
Dispose of the media in an environmentally-friend-
ly manner according to the local regulations.
2.6 Avoiding damage to property
There must be no corrosive substances in the ambient
air at the location where the heat pump is installed, or
in the air drawn in as a heat source!
Substances such as
●
ammonia
●
sulphur
●
chlorine
●
salt
●
sewage gases and flue gases
can cause damage to the heat pump, which may re-
sult in complete failure or irreparable damage to the
heat pump!
►
Make the outdoor connections and insulation
UV-resistant on site.
Frost protection
Do not disconnect the unit from the power supply, un-
less the unit is being opened.
Decommissioning / Draining heating
If the system / heat pump is taken out of operation or
drained after it has already been filled, you must en-
sure that the condenser and any existing heat ex-
changers are completely drained in the event of frost.
Residual water in heat exchangers and the condenser
can lead to damage to the components.
►
Completely drain the system and condenser, and
open the vent valves.
►
If necessary, blow out with compressed air.
Improper action
Requirements for minimising scale and corrosion dam-
age in hot water heating systems:
●
Proper planning, design and commissioning
●
Corrosion-resistant system
●
Integration of an adequately dimensioned device
for maintaining pressure
●
Use of demineralised heating water or VDI 2035
equivalent water
●
Regular servicing and maintenance
