4.5 Installation with draw lead
4.5.1 Calculation of the length of the draw lead
Overview
Because of the tolerances in the length of the porcelain, a nominal lenght for the draw lead can not be given.
The actual distance between the inner terminal and the sealing surface of the flange must be calculated.
Procedure
1.
Measure the length (L2).
2.
Subtract 350 mm from the L2 measurement.
L2 - 350 = draw lead lenght from the flange.
End of instruction

CAUTION!
Make sure that the draw lead is sufficiently long.
