NOTE!
Danger due to the ingress of electrolyte from the battery or due to operation
without any back pressure.
This may result in damage to the air pump.
▶
Always set up the charger at least 0.5 m (1 ft. 7.69 in.) above the battery to
be charged.
▶

pose to connect the charger's compressed air outlet to the battery.
NOTE!
Danger due to non-observance of the permissible mains voltage tolerance.
This can cause malfunctions and damage.
▶
For the electrolyte circulation option, a restricted mains voltage tolerance
vis-à-vis the charger of 207 V to 250 V applies.
The electrolyte circulation option introduces air into the battery through capil-
lary tubes that are provided specifically for this purpose. This allows intensive
