hi all went to a new Condenser installation by our company today aw43lmyb3 1.4kw low temp and found it controlling a muller mnd029 2.9kw . 15mtr horizontal pipe run . found evap iced in morning ,cleared and adjusted defrost settings , later afternoon found evap iced again and maintain max -7c . then found condenser undersized and old tx valve still on 502 require replacement . suction not to bad on 404a

suc/ -20
dis/ 45 c @ 30c amb.


As this is an incorrect installation is the evap coil forming ice within 10mins a main sign of an undersized condenser not feeding evap , or should i replace the tx valve and possibly get the system to perform ?
There is other issues with using another condenser
Single phase unit not available anymore
no space to install unit as its on a rack and new units are increased dimensions .
- One of our techs has already quoted this job and now i need to clean mess up quickly ! thanks for any input
