Wall hung toilet movement pre-silicone

[Boothus]

Hi, just installing a wall hung toilet on a grohe duofix frame + hardie + metro tiles.

All fine so far, just pushed the pan on rods and tightened as test run before attaching flush pipe and waste.

When fully tightened I can still lift the pan up slightly I.e. bottom of pan comes away from wall a bit. Seems to be because the rods have a tiny bit of up/down movement within the thread of the frame.

What would you do? Pack out the bottom a bit? Or run a bead of something around the back of the pan before pushing it on? Or will it solve itself once I silicone around it?

Thanks

Can you tighten the bolts the go into the frame half a turn ?

Do you mean screw the rods in further?
I’ve just seen that the geberit kit when bought separately seems to come with two nuts which weren’t included in my set. Should those nuts secure the rods in the thread of the blue frame? At the moment I can just adjust them in and out by turning.

Figured worth mentioning: I used the kit that the pan came with to fix the pan to the wall (1st pic)

but Geberit have also provided an alternative which looks like this (2nd pic)

Should I be using the Geberit one that’s just tightened with a spanner?

Update: used the grohe set instead and whilst it’s a ballache to get to from the bottom of the pan managed to tighten that up nicely so no movement now.
