Safety Air Exhaust/Installation Position
To provide protection against excess pressure which can build up in the inside of the
control top, a vent plug (E2) is fitted in the base.
In operating mode, the exhaust air from the lifting actuators is discharged via this vent
plug. In the unlikely event of a damaged solenoid valve or in case of sealing problems,
pressure relief is ensured.
Control Top with Cap
This vent plug is a safety device that must be handled as such. Do not cover the vent
plug. When fitting the control top note that the installation position of the vent plug (E2)
must never be pointing vertically upwards.
