INTRODUCTION

The Scavenger™ Refrigerant Recovery Station removes contaminated or unknown refrigerant from automotive A/C systems to prevent the cross-contamination of a service station’s R-12 and R-134a supply.

It is designed specifically for use with a refrigerant identifier capable of determining if the refrigerant is R-12, R-134A, or some other (unknown) refrigerant. In the case of an unknown refrigerant, the service technician can use this station to recover the refrigerant into a special 50-pound tank for transport to a disposal facility.

Model 176802K Scavenger™ Recovery Unit

Setup Instructions

To initially set up the station for operation:

1. Unpack all components and verify you have the following: (1) 50-pound refrigerant tank

(1) 96" Blue Enviro-Guard® Hose for R-12 (1) 96" Blue Enviro-Guard® Hose for R-134a (with adapter)

Please read this operating manual, and fill out and return the warranty registration card.

2. Connect the two 96" blue hoses to their respective 1/4" flare and 1/2" Acme inlet

NOTE:

The numbers in parentheses correspond to the callouts shown in the diagrams on page 5.

ports (7) on the back of the station. (Connect the hose ends without the valves to the station.)

The inlet ports on the back of the station are capped for shipment. Both hoses must be connected to the station during recovery, or the unused port must be capped. When not in use, the hoses can be wrapped around the station’s handle.

3. The station is equipped with its own regulator (6) that has an inlet with 1/4" female pipe thread. A male air line connector (not included) that matches your air system must be connected to the regulator.

4. The station is equipped with its own air line lubricator (4) to lubricate the air motor that runs the compressor inside the unit. This lubricator must be filled with

/4 oz. (22 ml) of pneumatic air line oil or detergent SAE #10 motor oil.

Unscrew the plastic bowl on the lubricator and fill with oil to approximately 1/2" below the top of the bowl. (Do not lose the o-ring on the top of the bowl.) Replace the bowl on the lubricator. Snug down, but do not overtighten.

IMPORTANT: The bowls for both the lubricator and regulator are made from polycarbonate. Oils used in the lubricator bowl must be compatible with polycarbonate. Some “fire resistant” oil additives are not compatible; do not expose bowls to acetone, trichloroethane, gasoline, alcohols, ketones, esters, chlorinated hydrocarbons, or toluene. Wash the bowls only with warm water or kerosene.

5. The tank supplied with the Scavenger™ is filled with 10 to 15 psi of dry nitrogen which must be removed before it can be used. Open the tank valve to release the nitrogen. Use a separate vacuum pump to pull a five-minute vacuum on the tank.

6. The tank is now ready to be connected to the recovery station. Place the tank on the platform just over the axle on the rear of the station. Tighten the black strap securely around the tank. Connect the black 3/8" hose (2) coming from the back of the station to the 3/8" flare fitting on the tank’s blue (LIQUID) valve.

7. Connect the yellow float switch cable to the tank.
