Mounting guidelines 

Drill two holes at least 90 mm in depth using an electric impact drill with 

a Ø 10

mm bit. The holes must be 

level. Space between the two holes should be as shown in the table. 

 

 

 

 

plastic expansion tube must be placed into the drilled 
holes before the brackets are inserted. 

It is necessary to use a special inner hexagon spanner to fasten the bolts into the expansion tubes, no other 
tools are permitted. Ensure the screw is not excessively tightened. This may damage the expansion tubes.

 

Insert the square holes of the upper of supporting rack at the back of the water heater onto the brackets, 
then press the water heater down firmly to ensure the holes are lodged against the brackets.
