Cleaning and maintenance
7.1
Cleaning
Clean the door handle with a slightly damp cloth. Use only commercially
available household cleaners.
Do not use any abrasive or caustic cleaning agents.
7.2
Maintenance
7.2.1 Replacing the battery
CAUTION
Danger of injury caused by improper use
Do not charge, open or heat the battery.
Always replace discharged batteries with new batteries.
Pay attention to the correct polarity when inserting the
batteries.
Change the battery only with the door open. As long as the battery is removed,
the door handle cannot engage and thus cannot open the door.
Using the Allen key provided, countersink the screw on the inside of the door
handle.
Remove the gripping sleeve.
Remove the used battery and insert the new battery, paying attention to the
polarity. The minus pole of the battery faces towards the gripping sleeve.
If the door handle is used outdoors, then replace the sealing ring of the door
handle (see chapter 7.2.2 Replace the sealing rings, page 38).
Insert the gripping sleeve back.
