Guys we need help

We have relocated x2 LUVATA - CAP0251P condenser units (fan & coil) roughly 1m from their original location. The refrigerant gas is R410A. The condensers are connected to
UNIFLAIR SUAC0151B. We have recovered the gas from the outdoor units, carried out the works, pressure tested, vacced out then charged with new R410a. When turning the units on we are getting a fault code - Low Evaporating Pressure on both systems. We haven't carried out any internal works but the fault keeps coming back after 5mins of running. Should we of replaced the filter driers? 6kg was pulled out so we charged with the same - pipe work is 1/2 5/8 roughly 45m.

We mainly work on AC - Vrfs Vrvs Splits
