Vecton V2 600 UV sterilizer

[Kitekat87]

I've just purchased this and hoping someone with experience with this unit can answer some of my questions please.

Can it be mounted at an angle?
Should it be connected to the outflow pipe?
Should the bulb be replaced every 6 months or 12 months?
When replacing the bulb do the pipes need disconnecting?
Will it affect the outflow of the filter?

I think that's everything for now
