NOTICE: 

System damage through inadequate load 

bearing capacity of the supporting surface or unsuitable 
substrate.

B

Ensure that the installation area is level and offers 
sufficient load-bearing capacity.

WARNING: 

Risk of fire through soldering and welding!

B

Take appropriate safety measures when soldering 
and welding as the thermal insulation is flammable. 
For example, cover up the thermal insulation.

B

Check cylinder casing after completion for perfect 
condition.

WARNING: 

Risk to health through contaminated water!

Work carried out without due care for cleanliness 
contaminates the potable water.

B

Install and equip the DHW cylinder hygienically in 
accordance with national standards and guidelines.
