Installation position

3.3.2
Units without additional shaft bearing in the extension
arm: Use only with a vertically suspended shaft (±5°).
Exception: If the shaft is rigid (not flexible) and not longer
than 200 mm and the bulk material is light-weighted, an
angle of inclination of max. 90° is permissible (allows side-
mounting with horizontal shaft).
In case of lateral installation (horizontal shaft): Install the
unit in such a way that the cable glands are on the
underside of the housing.
The unit head can be turned (2) after the clamping screw (1)
on the underside has been released.
The clamping screw must be fixed to achieve operational
condition.

If protection class IP 65 is required (European standard
EN 60529): Provide
between device and container.
If the paddle does not go through the container opening:
Detach the paddle before mounting and re-install after
mounting.
Height adjustment (option)
The height adjustment device is a clamp-ring fitting which
allows to fix the protective tube at variable insertion depth.
1. Install the threaded base part of the fitting in the container
wall.
2. Put the clamping nut and the clamping ring over the
protective tube.
3. Guide the protective tube through the base part of the
fitting (caution: do not damage the sealing rings inside
the fitting) and bring it into the desired position.
4. Guide the clamping ring into the fitting. Screw-up and
tighten the clamping nut.
5. Install the paddle.
Temperature protection by height adjustment
The height adjustment device can also be used to keep the
unit head away from high container temperatures.
● Important: This feature applies only to units equipped
with »DTR« type bearings.
Mounting instructions:
Adjust the height to a level where the distance between
unit head and container is at least 200 mm (7.9").
If the container is equipped with a thermal insulation:
Remove the thermal insulation around the protective tube
page 7, § 3.3.4).
(instructions
When these conditions are kept, the unit can be used with
container temperatures up to 200 °C (392 °F).
