    Upright for vapour withdrawal ,flip it over for liquid !(presuming you only have one valve and no dip tube)
    R22 can be charged as a vapour as it is not a blend.

    Re: 2 question

    As many as required !!!!
    No one is going to complain about the price of a few screws.
    But they will complain if the A/C unit falls off the wall and lands on their kid.
    Use common sense .
    Most manufacturers provide screws for mounting the plate ,so count them ,and use it as a guide line.

    Re: 2 question

    i hung a daikin 71 cassette off 6 tech screws holding 41 21 strut to a duct- then i fitted 41 41 strut with rawl bolts then droprods to transfer the load-as for the elusive question no 1- 1 fixing in the centre of the bracket to allow for exact centring- then 2 at the top corners to keep the top lip of the brcket tight to the wall, then 2 in the lower corners for where it clips onto the indoor unit- some manufacturers show on the installation instructions where they want the fixings, as long as the bracket is firmly fixed to the wall,typically the indoor only weighs around 7kg-unless its a 10kw wall mount that are upto 30kg!!-i remember getting called to an ac unit hanging off the wall- turned up and low and behold an imi cu80 was at 40deg only held on with its bottom fixings- had to re secure it whilst still piped up!

    Re: 2 question

    still fitting it-dont worry its bombproof!
    did an install years ago-had 2 cassettes in a bp station- as it was just a corrugated tin cladding roof- no steelwork to fix off and was a rush job- from the drop rods off the cassette had to use standoff brackets for tray -and 4 1 1/4 pozi with washers on each corner- still up 10yr later!!but as the outdoors was mounted straight on the butyl rubber roof they moved a bit in the wind! haha

    Re: 2 question

    Just put in as many as you can, there will be holes in the bracket, so just use that as a guide to how many!!

    The more the better!

    I can't quite understand the problem, unless your buying an exact amount of screws to do this with, in which case just buy a handfull and bung them in!

    Re: 2 question

    OK,
    True answer... 0 (zero), you don't need any screws at all...

    A few years back I were asked to do an install in a "tanked" room, no penetrations through the membrane was allowed.
    Pipework down the stairs and wall mounted unit glued on to wall using epoxy resin.
    It stayed up for at least 5 years but I haven't been back there for a while so it might have dropped of by now.
