NOTICE
Damage to the device, malfunctions and reduced lifetime of the device
caused by ingress of moisture, dust and dirt
After removing the housing cover, the O-ring may slip out of the provided
groove (left figure) which will result in loss of tightness.
➡
Before re-attaching the housing cover, make sure that the O-ring is seated
correctly (right figure) to ensure optimum tightness.
To simplify insertion into the provided groove, slightly overstretch the
O-ring several times beforehand.
