CAUTION!
The weight of the probe tube with filter unit amounts to approx. 50 kg!
Two persons are needed for transportation and mounting!
Observe the "Piping Plan" in the drawings set.
The type 40W probe tube must be installed in the smoke chamber almost in vertical
orientation (see Figure 3, page 28).
The probe tube must be installed in a protection pipe with the following character-
istics:
Material: Mild steel
Length: 3.0 m (for protection of the heated part of the probe tube)
Inner diameter: 50 mm or 100 mm for probe tube without or with prefilter
Flange: for connection to the flange of probe tube, location min. 300 mm
above the roof of the smoke chamber or its platform
Due to the probe tube's length (normally 3.5 m, 4.0 m or 4.5 m), it can be necessary to
make a hole in the roof above the smoke chamber in order to install the probe tube as
well as the protection pipe.
Installation of the protection pipe is preferably carried out during a shut down of the
kiln. The opening should be closed with a blind flange until the installation of the probe
tube takes place.
Step Action
1 Remove the blind flange from the protection pipe and lay on a flange seal
on the protection pipe flange.
2 Insert the probe tube from above in the protection pipe.
Do not damage the electrical connection (porcelain terminals) of the
probe tube heating at the probe tube flange!
3 Lay on the supplied flange seal on the probe tube flange and mount the
filter unit.
4 Interconnect the 3 flanges with bolts and nuts.
5 Mount the heating sleeve on the filter unit.
6 Connect the cable of the heating sleeve to the terminals in the terminal
box of the filter unit.
7 Connect the cable of the probe tube heating (2 x 2.5 mm
connection of the transformer in the back-purging unit.
