hanging upvc door tommorrow help please

[hardtail]

hi there wonder if you can point me in the right direction as to hang this door ,its a upvc one which ive just removed the inner panel as to lighten it a bit ,now i know the opening has 5 mm approx eitherside and 10 mm height clearence as ive done the brickwork .could you tell me where to use the packers is it about 6 "from top and bottom eitherside and one in the middle ,the sill is setting in the bricks overnight so hopefully solid for the morning many thanks tim
p.s do you lock the door i.e enguage the hook lock prior to packing the frame to keep it square in the frame

Packers you are ok with.

As for fixing the frame, just latch the door but dont engage the hooks, square the frame up as best you can but no need to be bang on as you can fine adjust when you toe and heel the door itself.

I assume you know how to toe and heel!
