3.  Mount the vessel vertically with the 

connections at the bottom using 

suitable fixings and a strap type 

bracket:

8 litre vessel  BRKT240022 

12, 18, 24 litre  BRKT240050  

 

 

Note : Expansion vessels should 

always be mounted in vertically 

with the connections at the bottom 

to avoid the possibility of sediment 

and debris being deposited inside the membrane and 

providing a possible breeding ground for bacteria such as 

Legionella.
