ok went back to site today.after speaking to the technical bloke in the suppliers heres what i did.
1. fit new filter drier
2.fit new valve and orifice no:3

also spoke to the original engineer who wasnt sure if he charged unit with134a or 407c-as supplied and confirmed with technical bloke at the suppliers-who got a bit grumpy i think
ran unit and here is what i got

unit:beermaster bmo150-1
refrigerant:r407c
room temp at time:+17 celcius-evap display
suction:4.4 barg/62 psi
discharge:14 barg/200 psi
suction line temp by expansion bulb:+12 celcius
liquid line @expansion valve:+23 celcius
liquid line into condenser:+56 celcius
liquid line leaving condenser:+31celcius
air on evap:+18 celcius
air off: +12 celcuis
cond air on:+18 celcuis-my thermometer
air off:+29 celcuis
i work this as givin me a superheat of 6 celcius and it seems to pull temp -at15 when left .no condensation on compressor.going to return on thursday and see how it running.what do all of you think of the above?i know it a bit long but thanks again.

You still have big drop of liquid line temperature (8K) from condenser to TXV.
Describe what is at that line and its length (together with elbows valves etc...) and insulation and temperatures at pipe location.
