Re charge procedure is it correct?

Hi
Just put a Mitsubishi SRK50ZIX-S and had no gas in it( 2nd hand) and now it turns on but the inside fan is running but the shutters are closed and outside compressor not running?
Can u check my method please as below.

Evac for two hours down to 250microns
Fit gas and purge at gauges to get rid of air and invert
Both valves still open(should i have closed one?)
Unit not running at this stage
Fill with 1.4kg of gas but only took 1.1kg
let settle for a few minutes
Turn on to cooling and run
turn off( think i should have left it running?)
let 300g gas in
Disconnect gauges
Unit wont run

Have i done this correctly, have i #@$%^ it?

Hope you can shed some light on it or a least verify my procedure?
Cheers

3 minute delay on start up of outdoor unit, did u put the indoor cover on properly - u can prise the louvres into an open position - mitsi dont have a limit switch on the louvres- u can unplug the louvre on the indoor pcb.

similar uk version - service manual

The problem is not just that the louvres dont open its more that the thing dont start up ie the outdoor fan is not turning?

outdoor fan will start up about 20 seconds before the compressor starts- check ur connections on the interconnecting.

OK will do and thanks for the link but does my charging procedure look sound to you?
I have another one to fully re charge and was wondering if i had caused damage somehow by the way i charged it?

page 32 of the manual shows a flow chart, best to give it a long vac if the service valves were left open.
your method is ok except for prior to vaccing - pressure test with oxygen free nitrogen to upto 40 bar- if r410a to proove all is ok before vaccing

Hi
FYI the problem was i did not have the original remote i bought a universal remote that appeared to work (made all the beeps etc) but in fact didnt. Found a remote and away it went!
Thanks for your suggestions
