3 The purpose of the Moblvac® III is to perform all routine suctioning procedures. These may include tracheal and oral aspiration, wound drainage, gastrointestinal, and thoracic drainage. The Ohio Medical Moblvac® III is a multipurpose suction unit designed for general use in the hospital, surgery center, and physicians offices. Because of the Moblvac® III’s capacities, it can also be utilized as a back up to wall vacuum system. The Moblvac®’s constant and intermittent suction capabilities are driven by a fan cooled, rotary carbon vane pump. It comes equipped with a disposable exhaust filter, an in-line suction filter with 14” of tubing, a disposable 1200cc collection canister with mounting bracket, and a preventative maintenance kit.

PUMP CLEANING NOTE: The heart of the Moblvac® III is a rotary carbon vane pump. It is NOT recommended that the pump be disassembled for routine cleaning. However, if performance has been affected by the pump becoming contaminated with aspirant, or if an overflow problem has occurred, the following procedure should be performed. 1.

Remove the pump assembly from the Moblvac® III as described above in the PUMP REPLACEMENT section.

2.

Remove the three (3) pump head screws located on the pump head.

3.

Remove the cover plate, shim, wear plate and the four (4) vanes.

4.

Wash all exposed areas with an isopropyl alcohol solution.

NOTE: Before you reassemble the pump make certain that all components are completely dry. Rust is likely to form if any moisture is present. 5.

Replace the vanes, wear plate, shim, and cover plate.

6.

Replace and equally tighten the three (3) pump head screws.

7. Reinstall the pump assembly. 3. PERFORMANCE TEST AND ADJUSTMENT The Moblvac® III’s maximum vacuum on both “Constant/Intermittent” and the flow rate on “Intermittent” are present at the factory. Due to various circumstances, readjusting these levels may be necessary. It is recommended that you verify the specifications and the performance of the Moblvac® III after: - An overflow. - Preventative maintenance. - Any maintenance. To verify pump & regulator operation: 1.

Plug the power cord into an electrical outlet. Turn the unit ON (I) and listen to verify that the pump starts.

2.

Open the vacuum outlet located at the top of the backpole assembly and place your finger over the outlet.

Ohio Medical Corporation, 1111 Lakeside Drive, Gurnee, Il 60031-4099 (800)662-5822-Fax: (847) 855-6218 www.ohiomedical.com -– 550102 (Rev.6) 08/2005

12 3.

Switch the unit to “CONSTANT” with the “MODE SELECTION” switch.

4.

Adjust the vacuum level by turning the vacuum regulator knob. Verify that the vacuum gauge reflects a change in vacuum level while turning the regulator knob. Also verify that you feel vacuum at your finger tip.

5.

Turn the unit OFF (O).

The following steps will verify the flow and the vacuum specifications: 1.

Connect a suction flow measuring device to the vacuum outlet of the Moblvac® III.

2.

Turn the unit ON (I).

3.

Adjust the Moblvac® III to full vacuum and verify that both the flow and vacuum specifications match the figures found on page 17 of this manual.

To adjust the vacuum level, locate the vacuum relief valve on the solenoid manifold. 1.

Turn the relief body (large knurled knob) counterclockwise to loosen while turning the locking ring (small knurled ring) clockwise. Do not remove the relief body, only loosen.

2. With a vacuum testing device attached to the vacuum outlet (located at the top of the backpole), turn the unit ON (I). Switch to “CONSTANT” suction and adjust the vacuum regulator knob, located on the control panel to full vacuum. 3.

Slowly turn the relief body until you reach the vacuum specification found on page 16 of this manual. Once the desired vacuum level has been reached, and while holding the relief body in place, turn the locking ring counterclockwise until it locks the relief body in place.

To adjust the flow level for intermittent, locate the flow adjustment valve on the end of the solenoid manifold. There is no adjustment to be made for the flow level on “CONSTANT”. 1.

With a flow testing device attached to the vacuum outlet, turn the unit ON (I). Switch to “INTERMITTENT” suction and adjust the vacuum regulator knob, located on the control panel to full vacuum.

2.

With a 1/16” Allen wrench, loosen the set screw. Turn the flow adjustment valve until you reach the flow specification found on page 17 of this manual. Tighten the set screw.
