*) Speed max. 200 rpm; if necessary, put the keyhole saw down once in a while to remove
drilled material. If this material is not completely removed, the tank material heats up and
starts to melt; Interrupt the cutting process, allow to cool and clean the keyhole saw; Lower
the speed, vary the feed pressure, and then maybe change the direction of rotation (anti-
clockwise rotation max. 200 rpm), until there is no more material.
NOTE: Check to make sure that the cut diameter is 175 mm for DN 150 or 124 mm for
DN 100 once in a while, since the leak-tightness of the pipe connection depends on this
decisively.
1.
• Define the position of the middle of the inlet – and mark it
• Cut the hole using the keyhole saw Ø175 (DN 150)
• Make sure the excess material in the drill bit is removed
completely. *)
2.
• Make sure the cut surface is clean!
Remove burrs!
3.
• Insert the inlet seal
• Moisten the inner surface of the seal with lubricant
4.
• Insert the inlet pipe – HT pipe DN 150
5.
• Push-in depth:
minimum 30 mm beyond the seal,
maximum 300 mm above the base of the tank.
6.
• Connect the inlet pipe and inlet seal using hose clips.
• Set the pipe clips correctly in order to secure the inlet pipe
to prevent it from slipping in the seal and in order to hold
the weight of the pipe.
