Connecting the ventilation pipe

The connection of a ventilation pipe is mandatory. Furthermore, ventilation is necessary to make sure that the lifting unit functions correctly. Follow these points to connect the ventilation pipe:

• A 2.5 m ventilation hose with Kamlock coupling is included in the scope of delivery. Make sure to use the ventilation hose to permit the dismantling of the cover of the supply box/distributor if necessary.
• For dry installation in buildings, route the ventilation pipe over the roof of the building.
• For underground dry installation outside buildings, route the ventilation pipe over the surface. Install the ventilation pipe with gauze and a rain cap 60 cm above the ground surface level.
• Make sure that all connections are fully tight.

1. The lifting unit is installed.
2. The ventilation pipe is laid.

1. Attach the ventilation hose to the hose clamp (Kamlock coupling).
2. Open the handles of the hose clamp (Kamlock coupling) upright.
3. Route the ventilation hose to the stationary ventilation pipe.
4. Attach two clamps on the ventilation hose at the side that is connected to the stationary ventilation pipe.
5. Push the ventilation hose on the stationary ventilation pipe and fasten with the two clamps. Tightening torque: 5 Nm (3.7 ft·lb).
