Replacement Condensers Charge Level Adjustment May be Necessary
2
Most Vehicles Use Flat Macro or Micro Tube, Multi-pass, Condensers Virtually Impossible to Flush After Compressor Failure Will Need to be Replaced. Sub-Cooling Condenser Multiple Passages In Header Tanks 2
3
Condenser Technology Has Advanced Replacement Condenser May be More Efficient (or Less) than the Original Unit Replacement (Including OE) May not be an Exact Match for the Original Unit Tube & Fin May be Replaced by Flat Tube Multi- pass Micro Tube Unit Flat Tube Multi-pass Macro-Tube Might be Replaced with Thinner Micro-Tube Unit. System Capacity May be Affected 3 Flat Micro-Tube Flat Macro-Tube

5 Replacement Condenser 1 - Muti-pass Tube & Fin (Piccolo) Design – Older Technology Pp
6
6 Replacement Condenser 2 - Very Large Flat Tube, Single Pass, Serpentine Flow – Older Technology Pp
7
7 Replacement Condenser 3 - Flat Micro-Tube, Multi-pass Flow – New Technology – Very Efficient Pp

8 1. Tube & Fin Piccolo 3. Flat Micro-Tube, Multi-pass Flow 2. Very Large Flat Tube, Serpentine Flow Pp
9
We Evacuated Each Condenser & Charged it with Liquid Refrigerant They Held: 1. Piccolo = 47 oz. (Matches O.E.) 2. Serpentine = 43 oz. 3. Micro-Tube = 26 oz. We Need to Adjust Original Charge Amount 9 Piccolo Condenser Held 47 oz. Pp
10
Compare Original and Replacement Unit Dimensions Basic Design – Flat (Micro or Macro) Tube, Serpentine or Multi-pass, Tube & Fin? Compare # of Tubes Size of Header Tanks Connection Line Diameter # of Cooling Fins/Inch Condenser Thickness 10 Pp
11
Perform Temperature Test to Validate Charge Level Start at 80% of Original Charge Add 1-2 oz. Increments Monitor the Three Dees Condenser Drop 20-50 Deg F Ambient to Duct More that 30 Deg. Difference Final Charge May be More or Less than Original When Evaporator Inlet/Outlet Difference = 0 Deg. F Charge Level Correct 11 Pp
