Installation on the basin wall
Fig. 3:
Mixer installed on the basin wall with a
mounting bracket
In this type of installation, the mixer is mounted either on a separate mounting bracket or
directly on the basin wall. The separate mounting bracket can be used to adjust the angle of
the mixer either vertically or horizontally. The design of the basin determines the installation
position and angle. Lay the connection cable against the basin wall and lead it upwards.
✓
Operating space/installation location is prepared for the installation. Defined clearances
to fixtures and basin walls are kept in accordance with the consulting documents.
✓
Mixer is not connected to the mains.
✓
For installation at heights over 1 m, use scaffolding with a safety harness.
1.
Position the mixer at the basin wall using hoisting gear and mark the mounting holes.
2.
Set the mixer down outside of the working area.
3.
Drill fixation holes and insert anchor bolts.
NOTICE! Follow the manufacturer’s installa-
tion instructions!
4.
Once the anchor bolts have hardened in place, use the hoisting gear to place the mixer
on the anchor bolts.
5.
Attach the mixer firmly to the basin wall using the fixation material.
NOTICE! Follow the
manufacturer’s installation instructions!
6.
Lay the connection cable against the basin wall so that it is slightly taut.
CAUTION! If
the connection cable leads over the edge of the basin, beware of potential abrasion.
Sharp edges may damage the connection cable. Bevel the basin edge if necessary!
7.
Apply corrosion protection (e.g. Sikaflex): Fill the slotted holes on the motor flange up to
the washer.
