INSTALLATION INSTRUCTIONS
   
Operation:
The Oil Mate™ removes a small amount of used engine oil from the crankcase and blends it with the fuel to be burned during combustion. It replaces this used oil with an equal amount of fresh oil from a make-up tank.

Oil Mate™ Valve:
1. Disconnect the battery cables.
2. Install the low oil level sensor into the front port of the tank and position the sensor with the arrow pointing up.
3. Install the make-up tank elbow fitting in the bottom of the tank. Position the elbow in the correct orientation to allow the simplest plumbing of the make up hose. Torque the nut on the fitting to 9-11 ft-lbs or until washer is flush.
4. Locate the three locations on the engine to plumb the lines of the valve to. You will most likely need to replace a plug from the oil galley with a through fitting. Replace a fitting of the fuel return line with a Tee fitting. And also replace a plug on the oil pan with a through fitting.
5. Three Hydraulic Hose Assemblies will need to be made up. The recommended hose size is -04 approved hose for this application. All of the fitting connections on the valve are male 9/16-18 ORFS. Recommended fitting connections to the engine are also ORFS but may be whatever is readily available. One hose will connect port "F" on the valve to the connection of the engine oil galley (oil pressure from galley is normally around 45 psi). One hose will connect port "P" on the valve to the teed in connection of the fuel return line. One hose will connect port "S" on the valve to the oil pan fitting. These two hoses from port "P" and "S" are low pressure lines.
6. Connect the hose from the filtered engine galley oil connection to the fitting marked "F" on the Oil Mate™ valve. The fitting connection is male 9/16-18 ORFS on the valve. Torque the hose fitting to 10 - 12 ft-lbs.
7. Connect the hose from the fuel drain fitting to the fitting marked "P" on top of the solenoid of the Oil Mate™ valve. The fitting connection is male 9/16-18 ORFS on the valve. Secure the solenoid fitting and torque the hose fitting to 10-12 ft-lbs.
8. Connect the hose from the fresh oil return fitting in the oil pan to the fitting marked "S" on the Oil Mate™ valve. The fitting connection is male 9/16-18 ORFS on the valve. Torque the hose fitting to 10-12 ft-lbs.
9. Secure the hoses as required using the tie wraps supplied in the kit.
10. Connect the wires from the controller wiring harness to a battery voltage power source (12 volt or 24 volt). Use conduit to protect the wires.

Fresh Oil Make-Up Tank and Level Sensor:
1. Locate a mounting location for the Make-Up Tank (do not mount directly on the engine). The tank should be in a location where the fill cap is easily accessible and visual checks can be done easily. The tank must be in a position where the full level is no higher than 10.0 feet above the valve's make-up inlet connection and the bottom of the make-up tank is no lower than 6.0 feet below the make-up inlet connection.
2. Install the low oil level sensor into the front port of the tank and position the sensor with the arrow pointing up.
3. Install the make-up tank elbow fitting in the bottom of the tank. Position the elbow in the correct orientation to allow the simplest plumbing of the make up hose. Torque the nut on the fitting to 9-11 ft-lbs or until washer is flush.
4. Mount the tank in the location chosen using at least four of the six mounting slots and the 7/16-14 fasteners supplied with the tank. Torque the HHCS to 9-11 ft-lbs.
5. Cut the supplied -10 hose to the correct length to install between the make-up tank elbow and the Oil Mate™ Valve fitting at Port R. Install a hose clamp onto each end and push the hose onto the connectors. Slide the hose clamps into position and tighten.
6. Secure the hoses as required using the tie wraps supplied in the kit.
7. Locate a location to mount the low make-up oil indicator light. Preferably in the dash or a visible location.
8. Using the butt splices provided and 18 AWG wire, connect one of the oil level sensor wires to ground and the other wire through the indicator light to the 12 volt or 24 volt power source (see drawing).
9. Secure the wires using the tie wraps provided.

Finishing the Installation:
1. Install the oil drain plug.
2. Clean the oil filter head surface and lubricate the gasket surface.
3. Fill the clean oil filter with clean lubricating oil and install the filter to the filter head per the instructions supplied with the filter.
4. Refill the engine with clean engine oil.
5. Replace the engine's fuel filter with a clean fuel filter per the instructions supplied with the filter.
6. Fill the make-up tank with clean engine oil.
7. Note: If an air source is not readily available, the system is self-priming. It will take a few cycles of pumping air before the system begins to pump fresh oil. If an air source is available see note 8.
8. Prime the make-up system by applying approximately 6 psi air to the top port and plugging any vents. Remove the NPT Hollow Hex Plug from the top port of the make-up oil tank. Replace this plug with a filter-regulator set-up to supply air pressure. Use the supplied tapered black rubber plug to plug the center vent hole inside the vented Kelch cap on the make-up tank. Disconnect the hose connected to the fresh oil return fitting and route it to a container to catch oil. Increase the air pressure slowly in 1 psi increments until oil flows from the hose. Do not pressurize the tank over 8 psi. Apply air pressure until oil begins to flow from the fresh oil hose. Remove the shop air and reconnect the hose. Unplug the Kelch cap vent and reinstall the hollow hex plug.
9. Top off the make-up tank with clean oil and cap.
10. Reconnect all battery cables.
11. The system is now ready to operate. Restart the engine as you would after any oil change.
