7cdb Posted June 29, 2014 Report Share Posted June 29, 2014 (edited) Hi All, Did anyone here sit the assessment on 28th June for the Air Con Vettassess. Any help would be much appreciated to what they asked and how the day went. Many Thanks Indi I did if it was at North London college,I will find out result in a couple of weeks. Starts at 8am and we got finished at around 3pm. 5 of us on the assessment and even one bloke as old as me at 42 so there is hope for me yet! Loads of other lads there Plumbers,sparks etc all decent lads and all quite informal Starts with a bit of Q&A with assessor Then go into workshop and get a rigged up with a unit each (copeland con unit and Searle evap) You have a document to log all readings,then reclaim refrigerant from system,pressure test and vac out and finally re charge and commission. Gauges tools Torr gauge etc all supplied,all you need is to make sure you have safety boots on. Assessor wanders around between all of you asking questions,not trying to catch you out just to get a bit of a general feel for how and what you do. All pretty basic stuff if you are a fridge man. But do it correctly,like you should on site Then make up some 3/8" pipe work,flares,swayged joint,pipe benders etc. Braize it up and let him check your work. Then pop to lunch (a shop around the corner) After lunch it's electrical,test a 3ph motor,insulation and measure resistance of windings etc,check a couple of single phase comps,again log info and know what the measurements mean. Start,common,run windings etc. Make up a 1ph and 3ph lead. Finally draw him a simple control circuit,mains in through T/stat to feed Sol valve,make LP,clear HP and feed the coil of a 3ph contractor to put power onto a compressor. Final part is a 30 question multiple choice paper which you have an hour to do (3 of us finished it within 30 mins) so it shows how easy it was! I thought it it was quite easy,so this probably means I have failed miserably and have wasted a grand:shocked: Anything else ask away Edited June 29, 2014 by 7cdb Quote Link to comment Share on other sites More sharing options...
