Maintenance Of Accu Block; Disposal Of Used Accus - Vectron HW 90196 User Manual

4.4 Maintenance of accu block

If accu blocks are stored, they should be re-charged on a regular basis. After a period of 6-8 weeks, even
a new accu block is discharged to such an extent due to self-discharge that it is no longer possible to
operate a HW 90196 with it.
About how to store device and accu block see also 1.1 „Important comments for application".
IMPORTANT!
A stored MDE which is not used, has to be recharged once per month.
The maintenance and service of such accus which have not been used for a longer period may
be executed by the Höft & Wessels service department. For further information, please contact
our service line : Tel. (0049) 01803/ 23 28 29
As for maintenance of the accu block, the following points should be taken into account:
Good:
•
Daily use of the accu block
•
Total use of capacity (discharge) until display shows "attention! - recharge batteries!!!"
•
Re-charging with charging unit HW 16196 or communication station HW 50196
Bad:
•
Occasional use of accu block
•
Heat impact (increased self-discharging)
•
Frost impact
Very bad:
•
Total discharging
•
Humidity; aggressive gaseous substances, which increase corrosion of contacts
•
Storage with temperatures lower than -20°C
•
Charging with temperatures lower than 0°C

4.5 Disposal of used accus

"NiCd-accu cells contain between 15 and 20 % highly toxic cadmium."
(Source: test 12/88 p. 1175)
Used accu cells must under no circumstances be disposed with common household waste, as the con-
tained cadmium will result in heavy pollution of environment.
All used accu cells have to be disposed of in an appropriate way. For this purpose, they have to be re-
turned to Höft & Wessels. As a part of its normal service, Höft & Wessels guarantees that all used accu
cells are fed to the recycling process.
The return of the accu cells ensures 100% reuse of the chemicals contained. This recycling process
avoids any impact to the environment.
See also extract from BattV - 01.10.1998:
"The manufacturers are obliged to take back and reuse toxic containing batteries according to the regula-
tions and dispose of non-reusable batteries that have been handed in by distributors (§5) or public dis-
posal departments (§9)."
