4.5.1 Topping Off the Oil Level See 4.4 - Oil Capacity and Type on page 19 before adding oil. Also refer to 4.2 - Maintenance Tools on page 18 for information about the tools used in this procedure. Note Adding oil through the Schrader valve on either compressor suction fitting permits adding the oil with the compressor running. Adding Oil 1. Turn the knob on the backseating control valve fully counterclockwise. 2. Remove the protective cap from the Schrader valve on either compressor suction fitting and connect the backseating control valve. 3. Connect one end of the oil transfer hose to the backseating control valve. 4. Connect the opposite end of the hose to the oil transfer pump. 5. Pour PAO oil into a clean container and attach the extension hose to the threaded neck of the container. 6. Turn the knob on the backseating control valve clockwise to open the Schrader valve and slowly open the oil transfer hose ball valve. Caution When pressure is applied to the oil pump, the handle may extend rapidly. 7. Move the pump handle slowly using long, slow, full strokes on the pump handle to transfer oil into the Compressor until the desired oil level is reached. One full pump stroke dispenses 1.6 oz. (47ml) of oil (see 4.3 - Checking the Oil Level on page 19). 8. Turn the knob on the backseating control valve counterclockwise to close the Schrader valve and remove the control valve. 9. Replace the protective cap on the Schrader valve. 10. Return the Compressor Package to service. 11. Check for leaks at all fittings that have been disturbed. 21 2006SSD-75 R4 (10/10) Dual-Compressor Module Maintenance 4.5.2 Changing the Oil These procedures describe how to drain oil from the system and to replace the oil after draining. Figure 15 Adding or Draining Oil Draining Oil Under normal operation, the Compressor and oil circuit remain under pressure when the Compressor is turned off. This pressure can be used to drain most of the oil. It is also possible to use the gas supply pressure to force oil out of the Compressor Module. In some cases it may necessary to pressurize the module with an inert gas to remove the oil. 1. Turn the knob on the backseating control valve fully counterclockwise. 2. Connect the backseating control valve to the Schrader valve near the bottom of the first-stage oil separator, shown in Figure 15. 3. Connect one end of the oil transfer hose to the backseating control valve. 4. Place the free end of the hose into a suitable container and turn the knob on the backseating control valve clockwise to open the Schrader valve and open the oil transfer hose ball valve. 5. Leave the valves open until the oil stops flowing and gas comes out of the hose; close the valves. 6. Relocate the hose to the Schrader valve on the inlet of one Compressor and repeat Steps 5 and 6. Repeat for the other Compressor on the Compressor Module. 7. Move the hose to the Schrader valve on the oil cooler and repeat Steps 5 and 6. 8. Close the valves, remove the service hose and replace the protective caps on all Schrader valves. 9. Note the volume of oil that has been drained from the Compressor Module; replace the oil as described in the next section, Replacing Oil on page 22.

Turn the knob on the backseating control valve fully counterclockwise. 2. Remove the protective cap from the Schrader valve on the first-stage oil separator (shown at right) and connect the backseating control valve. 3. Connect one end of the oil transfer hose to the backseating control valve. 4. Connect the opposite end of the hose to the oil transfer pump. 5. Connect the 6” (152mm) extension hose to the oil transfer pump. 6. Pour PAO oil into a clean container and install the oil transfer pump. 7. Turn the knob on the backseating control valve clockwise to open the Schrader valve. Caution When pressure is applied to the oil pump, the handle may extend rapidly. 8. Move the pump handle slowly using long, slow, full strokes on the pump handle to transfer oil into the Compressor until the desired oil level is reached. One full pump stroke dispenses 1.6 oz. (47ml) of oil (see 4.3 - Checking the Oil Level on page 19). 9. After adding the same amount of oil that was drained from the Compressor Module, start the Compressors and verify that the operating oil level is correct (see 4.3 - Checking the Oil Level on page 2). If necessary, adjust the oil level (see 4.5.1 - Topping the Oil Level on page 20). 10. Turn the knob on the backseating control valve counterclockwise to close the Schrader valve. 11. Replace the protective cap on the Schrader valve. 12. Return the Compressor Package to service. 13. Check for leaks at all fittings that have been disturbed.
