dismantling Air con in commercial setting

assuming it has been decommissioned by an F-Gas engineer (insist on seeing and making a copy of the paperwork)

make it electrically safe, cut the pipes and control cable.

undo the 4 threaded rods and it will fall straight down onto the side of the bar.

thought there would be gas involved thats why i was checking on here not touching it now

lol i know that

If it looks like a job which requires an F gas professional to remove the refrigerant and decommission the external unit which it is connected to then yes it is that simple.

It would need 'pumping down' whereby one valve is closed at the outdoor unit and it's run untill all the gas is pumped into the receiver and then the second valve is closed. It would then be in the state it was originally shipped by the manufaturer before installation with the gas charge contained in the outdoor unit. Essentially it's the same kind of procedure as those DIY install air conditioners, there's no actual handling of the gas and there's no gas actually released if it's done right so I'm not sure if F Gas certification would be required in the UK but either way, if you've never done one before probably best to play it safe and get a refrigeration guy in to do the pumpdown.

Would be surprised if pumping down to release the high and low pressure lines is not covered by Fgas regs.
You would need to be competent at pumping down, you would need gauges to make sure you had reached vacuum in the low and high pressure side and you would need to confirm the receiver has the capacity to handle all the gas in the pipes. Many systems are not expanded so receiver capacity is as it is, i.e. big enough. But some multi- systems cannot handle all the gas by pumping down so has to be recovered to a bottle. the OP just shows one evaporator, who knows what else is out there.... In the UK and EU - the actual total gas installed is shown on the data plate, it should show one figure for shipped and another for additional gas added for that particular installation. The Fgas eng needs to ensure pumping down the total gas is doable.
Electricians - know your limits ! - lol
