2. GRUB SCREW INSERTION
a. Keeping NEO / NEO WIFI pressed against the heating element in the towel rail, make
sure the grub screw is in its right positioning spot (grub screw seat) as shown in figure
below.
b. Using the provided Allen key tighten the grub screw until it comes into contact and it is
fully inserted in its spot, so that the NEO / NEO WIFI is securely fixed to the electric
heating element and the O-ring gasket is well in contact with both surfaces
c. Make sure the grub screw is NOT in other wrong positions by checking the alignment
with the back of NEO / NEO WIFI, as shown in figure below.
