Subject to change without notice | 83057000jUK – Translation of the original operating manual | ait-deutschland GmbH
Existing earthing connections within housings or on
mounting plates must not be altered. If this should ne-
vertheless be necessary in the course of repair or as-
sembly work:
►
Restore earthing connections to their original con-
dition after completion of the work.
Injury due to flammable liquids and potentially
explosive atmospheres
Constituents of antifreeze mixtures, e.g. ethanol,
methanol, are highly flammable and form an explosive
atmosphere:
►
mix antifreeze in well-ventilated rooms.
► Note the hazardous substance markings and
comply with the relevant safety regulations.
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 room.
3. Notify authorised customer service.
2.5 Disposal
Batteries
Improper disposal of the buffer battery damages the
environment.
► Dispose of the buffer battery in an environmentally
compatible way according to the local regulations.
Media harmful to the environment
Improper disposal of environmentally harmful media
(antifreeze, refrigerant) damages the environment:
►
Collect media safely.
►
Dispose of the media in an environmentally com-
patible way according to the local regulations.
2.6 Avoid damage to property
Decommissioning/draining the heating
If the system/heat pump is decommissioned or drained
after already being filled, it must be ensured that
the condenser and any heat exchangers have been
drained completely for the event of freezing temper-
atures. Residual water in heat exchangers and con-
densers can result in damage to the components.
►
Completely drain the system and the condenser,
and open vent valves.
►
Blow them clear with compressed air, if required.
Improper action
Requirements for minimum scale and corrosion
damage in hot water heating systems:
●
Proper planning, design and start-up
●
Closed system with regard to corrosion
●
Integration of adequately dimensioned pressure
retention
●
Use of deionised heating water (VE water) or with
water corresponding to VDI 2035 only
●
Regular servicing and maintenance
If a system is not planned, designed, started up and
operated according to 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.
