2. Steam out the tank to comply with safety regulations

3. Drill out the central bore using a bimetal core drill (or hole saw) ø35 mm

4. Drill out four mounting holes according to the diagram:

The mounting hole diameter depends on the material of the tank:

ø 4 mm – for metal tanks with wall thickness over 3 mm (cut M5 thread)

ø 7 mm – for plastic and metal tanks with wall thickness up to 3 mm (for rivets)

ø 4 mm – for plastic tanks with wall thickness over 3 mm
