Condenser and Receiver Drier Installation
Sub-Assembly
IMPORTANT: Keep all the A/C fittings capped and sealed until the installation of the refrigeration hoses. Refrigerant
oil is extremely hygroscopic and a system left open for more than 5 minutes may require extensive evacuation /
dehydration time to remove moisture.
NOTE: Read and understand Fabricating Refrigeration Hoses on page 30 for proper hose fabrication requirements.
Always use two wrenches while tightening refrigeration fittings.
Special Tools Required
Hose Fitting Tool (204-1045)
Hose Cutting Tool (204-677)
Alkyl Benzene Refrigerant Oil (670404TKA)
Torque Wrench
Place the condenser coil onto a workbench and sub-
assemble the following components:
•
Loosely install the Ambient Temp Sensor
clamp to the receiver drier bracket.
•
Install the receiver drier bracket onto the
condenser coil housing with the Ambient Temp
Sensor clamp to the back. Use supplied 1/4-20
mounting hardware and tighten securely.
•
Attach the two large hose clamps to the
bracket.
•
Install the receiver drier to the bracket with the
hose clamps and tighten securely. Use arrow to
verify correct direction of refrigerant flow.
•
Fabricate and install a #4 hose (5.00 in. long)
with two 90 degree fittings onto the INLET
fitting of the drier and the bottom OUTLET
fitting on the condenser coil. Tighten fittings to
the torque specs shown.
