Eddie Motorsports MS107 AC User Manual

PLEASE READ!

IMPORTANT INFORMATION ABOUT YOUR AC COMPRESSOR

All charging procedures should be performed by a licensed and certified technician. Installer and technicians should
read this sheet and all component instructions carefully before starting work. Please call if you have any technical
questions before, during or after the installation. Our knowledgeable staff will be glad to assist you with any
questions you have.

WARNING: Do not connect power to the AC clutch wire without first connecting hoses and charging the system.
Serious damage to your compressor can occur and the warranty will be voided.

The Sanden A/C compressor supplied with your Eddie Motorsports S.drive kit is pre-filled with oil and Nitrogen
charged from the factory to insure proper lubrication of the internals during storage and transport. Do not remove
the block off plate on top of the compressor until you are ready to install the hoses and charge the system.

Refrigerant

The Sanden A/C compressor supplied with your Eddie Motorsports S.drive kit is compatible with 134a refrigerant
which is commonly used in late model and aftermarket A/C systems. All part warranties are voided if any refrigerant
other than R134a is used. If your car is equipped with its original A/C system and components, it will be necessary to
convert your system to use 134a. Consult a reputable A/C system manufacturer for details on this conversion. We
recommend the factory air experts at Classic Auto Air 877-342-5526 www.classicautoair.com

System Charging Tips & Warnings PLEASE READ CAREFULLY BEFORE CHARGING YOUR A/C!

1. Please keep in mind that regardless of you or your technician’s experience, the charging processes for your Sanden

pump will vary greatly from stock OEM systems. Failure to follow these steps and proper charging procedures will
result in an improper installation or damaged item and WILL VOID YOUR WARRANTY!

2. DO NOT ADD OIL! All new Sanden compressors contain a full system charge of oil.

3. Before charging the system and putting power to the compressor, it is necessary to clear the oil from the
compressor head. With the belt removed and the lines hooked up, manually turn the compressor clutch hub (not the
pulley) a minimum of 10 complete revolutions to clear the oil.

4. DO NOT CHARGE THE SYSTEM IN LIQUID FORM. Unlike later model vehicles, doing so will direct liquid refrigerant
into the compressor piston chamber, causing damage to the compressor reed valves and/or pistons, as well as
potentially seizing the compressor. Doing so voids all warranty claims.

5. USE A CHARGING STATION TO EVACUATE AND CHARGE YOUR SYSTEM

DO NOT TILT, SHAKE OR TURN REFRIGERANT CAN UPSIDE DOWN DURING THE CHARGING PROCESS WHILE THE
ENGINE IS RUNNING! Evacuate the system for a minimum of 45 minutes before charging. Longer if possible. When

using a charging station, meter the refrigerant into the system with the vehicle turned off. Then allow a minimum of
30 minutes for liquid to “boil off,” or hand turn the compressor hub (not the pulley) a minimum of 10 complete
revolutions to clear liquid refrigerant from the compressor piston chamber.

6. DO NOT CHARGE THE SYSTEM THROUGH THE HIGH (DISCHARGE) SIDE OF THE SYSTEM! Refrigerant should be
administered through the low (Suction) side of the system.

Warranty

All compressors carry a 1-year limited warranty.
