Battery hazard, handling, shipping and 
recycling/disposal
 WARNING – DANGER
AquaMaster4 is available with choice of power 
options including lithium thionyl chloride battery 
power. This warning covers the health and safety 
issues regarding the product with such batteries. 
The following warnings must be observed:
• Only batteries approved by ABB that comply with 
the safety requirements of IEC60086-4 (see list 
under Battery power supply on page 15), or 
contained in the latest documentation from ABB 
may be fitted. Fitting of other types is not 
recommended by ABB.
• Do not use spiral wound lithium thionyl chloride 
batteries. These pose a very high hazard to 
personnel and a very high fire and explosion 
hazard. 
NEVER FIT THIS TYPE.
• Fitting of battery technologies other than 
lithium thionyl chloride is NOT permitted.
• Some forms of D batteries do not conform the 
‘D’ battery standard and may result in 
intermittent connection and incorrect product 
operation.
• Incorrect use or operation of batteries may 
result in potentially serious hazards to 
personnel.
• DO NOT expose batteries to fire or temperatures 
above 85 °C (185 °F) and DO NOT crush or 
puncture – they may leak, explode or rupture 
violently.
• DO NOT ship or transport the AquaMaster4 
with lithium batteries fitted unless the following 
instruction is complied with:
Transporting lithium batteries or product 
containing lithium batteries:
• These are classified in ‘category UN3091 – Class 
9’ of the UN list of hazardous materials. The 
transport of such battery packs must conform to 
the prevailing rules that are specific to the 
means of transport used, both in terms of 
packing, identification and accompanying 
documents. The carrier must always be informed 
of the contents. A warning label ‘Hazardous 
Label for Class 9 – Miscellaneous Hazardous 
Goods’ must be attached to the packing and 
remain visible on the outside of the package.
• DO NOT dispose of depleted or partially 
depleted batteries. They MUST be recycled in 
accordance with local regulations (for example, 
sent to a specialist recycling centre that handles 
such batteries). The batteries must be packed, 
labeled and transported in accordance with the 
regulations. Ensure the battery cannot be short 
circuited.
• Recycling in Europe must be in accordance with 
91/157/EEC and 93/86/EEC Directives.
• Damaged, leaking or overheated batteries 
require urgent specialist handling and 
treatment. Immediately evacuate all personnel 
from the area 
and seek professional assistance.
