[Stevie dee]

Hi Guys
We have just been handed a new contract and was sent to this Daikin system with one master and 2 x slaves as you can see from attached pictures it's well frozen up..I dropped gas charge and weighed charge R410A and it marries up with factory and trim charge...my next thing to look at was defrost and ambient air sensors..can anyone give me some advice on this??

Is outdoor above ground level if not defrost water could be freezing and building up from ground level at night when the temperature is freezing
