Operating instructions

The Heating Element must be used by well trained and autorized operators only!
3.2.1

Putting into operation

Please read the operating- and safety-instructions attentively before putting
the heating element into operation!
Do not use the heating element in explosive environments or bring it into
contact with easily flammable materials!
 Fit the corresponding heating jacks (8) and heating arbours (9). Secure heating arbour (9)
with counter pin (10) and thighten the screw M6x40 with allen key (s.fig. A).
 Insert the heating element with the mounting groove in a table clamp (no.: 55540) or floor
stand (no.: 55539).
 Connect power plug to the power supply stated on the type plate.
The red "Stand by" diode on the heating element lights up, which means: voltage is being ap-
plied. Switch on the heating element on the hand grip using the large press-button (lights up
green) and set the desired temperature using the "+" or "-" button (160°C to 285°C / 320°F to
545°F).
Heating is displayed on the hand grip by the yellow diode. Horizontal bars also appear on the
temperature indicator. The yellow diode goes out shortly before reaching the set nominal tem-
perature (tolerance +/-3°C / 5.4°F) and the green one lights up. The heating element is usable
after a further 10 minutes. Note: upon first reaching the nominal temperature the set value can
be exceeded for short time.
Check the temperature using an external temperature measuring instrument. If there are devia-
tions it means that the heating element must be re-calibrated: press the "+" and "-" button simul-
taneously and then set the difference using the "+" or "-" button.
If "Er1" appears this means the electronics are defective. For "Er2" the resistance thermometer
is either defective or not connected. Send the device to an authorised ROTHENBERGER speci-
alist workshop.
Very hot – Do not touch! The heating element can reach a temperature of
approx. 290°C / 554°F!

Preparations for welding

 The end of the pipe is to be chamfered as shown in fig 1 and set out in Table 1.
 The connection area of the pipe is to be machined as specified by the manufacturer of the
shaped piece.
 Make the insertion depth at the end of the pipe over a distance as set out in table 1.
