Install lifting unit so as to protect against buoyancy and twisting. Anchor the lifting unit
to the floor for this.
‡
Preparatory tasks have been completed.
‡
Installation location prepared according to consulting documents.
‡
Suitable fixation material provided for the existing building ground.
NOTICE! Ob-
serve the information on the fixation material!
1. Place the lifting unit at the installation location and align to the pipework.
CAUTION! Secure the switchgear to the lifting unit to prevent it from falling
down. The switchgear may be destroyed if it falls down!
NOTICE! Lifting unit must be standing level!
2. Mark out the boreholes of the fastening grooves.
3. Place the lifting unit to one side.
4. Drill and clean the boreholes. Insert the dowels.
5. Lay out and align the insulation mat.
6. Position and align the lifting unit to the insulation mat.
7. Guide the fastening screw and disc through the fastening groove. Screw the
fastening screw into the dowel.
8. Attach the lifting unit to the floor.
9. Attach the switchgear to the wall so as to be overflow-proof (see switchgear in-

Observe the following information when connecting the pressure pipe:
ƒ
Pressure pipe must be DN 80 or DN 100!
ƒ
Flow rate in the pressure pipe: 0.7 m/s (2.3 ft/s) to 2.3 m/s (7.5 ft/s)!
ƒ
Reducing the pipe diameter is not permitted!
ƒ
All connections must be completely tight!
ƒ
Install the pressure pipe as a “pipe loop” to avoid backflow from the main public
sewer.
At its highest point, the bottom edge of the pipe loop must be above the locally de-
termined backflow level!
ƒ
Install the pressure pipe so that it is protected from frost.
ƒ
Install the gate valve.
