I have set up the XPERT/XPERT Pro set and the spin is uneven – what is wrong?
Check your manual first! The most common cause for this is the positioning of the ceiling dome and base, see pages 11-13 of your manual. Firstly, the dome must be positioned directly underneath a ceiling joist – with the joist lined up to run down the center of the dome. If the dome is off-center to the joist it will push up on one side when installed and cause an uneven spin.
Secondly, the pole must be completely vertical – so the base must be positioned correctly underneath the dome. Use a spirit level if you are unsure if your pole is straight.
