Technical illustrations
The following description illustrates the retrofitting of a
precipitator on a size 1 eHACK boiler (20-45 kW) with
the fuel discharge on the left side.
The illustrations are equally representative for eHACK
boilers of size 2 and if the fuel discharge is located on
the right side.
DANGER!
Electric shock
There are live parts on the circuit boards. If
touched, they can cause injury and
property damage.
Before beginning any work, isolate the system
completely from all power sources, ensure that it
cannot be switched back on, and verify that it is
safely isolated from supply.
Align boiler horizontally
Place a spirit level onto the boiler's panel to check the
horizontal alignment; use shims as needed.

The horizontal alignment of the boiler is important
because the electrode in the precipitator must be
an equal distance away from the inner walls on all
sides.
Installing the sensor for the sliding rake position
Remove the panel from the rear of the boiler.
Fig. 2-2: Panel
Mount the additional sensor from the delivery scope in
the hole. The clearance from the plate should be about
2-3 mm.
Fig. 2-3: Sensor
If the current position of the plate makes it difficult
to adjust the distance, measure the distance from
the shaft to the end of the plate and add an additional
2-3 mm. Then mount the sensor at the correct distance
from the shaft.
