Upon arrival found unit with overflow pan full with water. Shop vac all water out and test run unit. Unit started cooling and everything looked good outside 300 psi 9° subcool 109psi 16° superheat. Upon further inspection found air coil inside was putting out 39° at the suction line and after the upwards U bend it reached 51°. Oil is likely slugging in coil suction line causing freeze up. Have to return, recover refrigerant, modify lineset to remove the suction line lift, and then recharge and test run system.
