Dispatched for system not operating. System had an error code for pressure switch. Checked both pressures switch’s and reset the system. After allowing system to reach 100% capacity it was showing low on refrigerant and that’s why the pressure switch’s were activated. After a thorough inspection for a leak. There was no detection of a refrigerant leak. This indicated that at completion of installation the correct amount was not added correctly. I resolved the issue by adding refrigerant and documenting the amount add. System is currently operating with in manufacture specifications.
