Jungheinrich ECE 220 Standard Operating Instructions Manual page 76

8. Battery hose connections
Hose connections for the individual plugs are laid along the existing electric circuit.
No changes may be made.
9. Operating temperature
The temperature limit for battery operation is set at 55° C. Exceeding this temperature
damages the batteries. The battery filling systems may be operated within a tempe-
rature range of > 0° C to a maximum of 55° C.
CAUTION:
Batteries with automatic water refilling systems may only be operated in rooms
with temperatures > 0° C (as there is otherwise a danger that the systems may
freeze).
9.1 Diagnostics hole
To be able to measure the acid density and temperature easily, the water refilling sys-
tems must have a diagnostics hole with a 6.5 mm-diameter (Aquamatic plugs) or a
7.5 mm-diameter (BFS plugs).
9.2 Float
Different floats are used depending on the cell design and type.
9.3 Cleaning
The plug systems may only be cleaned with water. No parts of the plugs may come
in contact with soap or fabrics which contain solvents.
10. Accessories
10.1 Flow indicator
To monitor the filling process, a flow indicator can be inserted into the water feed pipe
on the battery side. During the filling process, the paddlewheel is turned by the flowing
water. When the filling process ends, the wheel stops and this indicates the end of
the filling process. (ident no.: 50219542).
10.2 Plug lifter
Only the appertaining special-purpose tool may be used to disassemble the plug sys-
tems (plug lifter). The greatest of care must be employed when prising out the plug to
prevent any damage to the plug systems.
