Remove the bottom of the recess.
1a. To do this, use a keyhole saw (outer Ø
50-56 mm).
CAUTION! Risk of damage!
Remove the bottom from the tank, since
otherwise the unit could be damaged!
1b. If there is no correctly-sized keyhole saw
available, the opening can also be made
using a narrow chisel or sharp screwdriver
(max. 5 mm wide). To do this, move around
the entire circumference of the deep circular
groove with a sharp tool with light hits of a
hammer until the bottom slowly comes off.
CAUTION! Risk of damage!
When separating the lateral surface (Ø 65 mm)
(sealing surface) and bottom, don't damage the
tank!
• When using hammers and sharp puncturing
tools, only hit the hammer lightly. The tank
could crack!
• Remove the separated bottom from the tank,
since otherwise the unit could be damaged!
