About this file
This is a Performance Work Statement (PWS) establishing maintenance requirements for medical vacuum systems. The statement outlines a comprehensive preventive maintenance program structured by frequency intervals to ensure optimal system performance and reliability.
Daily maintenance tasks include monitoring vacuum suction pressure gauges and recording readings, inspecting pressure switches and compressor operation, checking for oil leaks and maintaining proper oil levels, verifying proper piping function, monitoring for excessive noise or vibration, and inspecting dental oral evacuation components. Tasks also encompass cleaning dental evacuation lines and filters, alternating pump operation, inspecting amalgam separator collection containers (with replacement required when full or every 12 months, whichever occurs first), and verifying all flexible hoses and connections for integrity. Monthly maintenance includes checking couplers for alignment and wear, inspecting strainers for clogging, verifying pump speed and amperage, and cleaning pump cooling fins. Quarterly maintenance requires oil changes following manufacturer specifications. Semi-annual maintenance covers inspection and lubrication of pump and motor bearings with replacement as necessary. Annual maintenance includes lubricating compressor and motor bearings, testing vacuum low and pressure switch operations, testing vacuum pump malfunction alerts, performing inspection and calibration of continuous suction regulators (with required documentation stickers showing inspection dates and next due dates), and certifying amalgam separator operation including waste handling and disposal procedures.

ATTACHMENT “C” MAINTENANCE FOR MEDICAL VACUUM SYSTEMS
Daily:
• Read vacuum suction pressure gages and record on log. Repair vacuum pump or vacuum switch if abnormal conditions are detected.
• Check that pressure switches operate within desired limits and readjust, as necessary.
• Check for proper alteration of compressors by the control system.
• Check vacuum pumps for excessive start/stop cycling and adjust and repair, as needed.
• Check discharge piping for obstruction and clear, as necessary.
• Check pumps for oil leaks. Investigate and repair oil leak, as necessary.
• Check oil level in crankcase and add oil, if necessary, to bring level to the full mark. Record on log if oil has been added.
• Read vacuum gage in inlet piping. Investigate and clear obstructions if readings are higher than obtained at the work or process area.
• Check process piping for leaks and/or malfunction valves.
• Check for excessive noise, heat, or vibration from the vacuum pumps and motors and repair accordingly.
• Read vacuum pressure gauges at all alarm panel locations and record on daily log.
Investigate and repair any line pressure variations from the normal operating range.
• Check Dental oral evacuation pumps for proper operation.
• Clean Dental oral evacuation lines as needed. Check and clean in-line filter.
• Clean solids collector on Dental oral evacuation unit weekly.
• Alternate operation of Dental oral evacuation pumps on every other day schedule so that the pumps are used evenly.
• Inspect Dental - Amalgam Separator collection container.
• Change the collection container (when full or once every 12 months, whichever comes first).
• Check operation of the vacuum pump.
• Check all flexible hose for kinks, breaks, or loose clamps.
• Check all connections for breaks or cracks.
• Listen for vacuum leaks.
Monthly:
• Check couples for misalignment, tightness, or excess wear. Replace or adjust, as necessary.
• Check for clogging of strainer and clean, as necessary.
• Verify that the vacuum pumps are running at the correct rpm or amperage and adjust, as necessary.
• Clean pump and cooling fins, as necessary.
Quarterly:
• Perform oil change by draining crank case of old oil and refill with new oil, as recommended by the manufacturer.
Semi-Annually:
• Checks pump bearings for wear. Lubricate or replace, as necessary.
• Check motor bearings for wear. Lubricate or replace, as necessary.
Annually:
• Lubricate compressor bearings.
• Lubricate motor bearings.
• Test operation of Vacuum Low and pressure switch for the vacuum piping system.
• Test operation of Vacuum Pump Malfunction.
• Perform inspection and calibration of continuous suction regulators. Work shall include unit inspection, calibration and any replacement of parts to keep equipment in optimal operating condition. Inspection/calibration stickers are required on each individual unit and are to include date of inspection/calibration and next due date.
• Certify the operation of Amalgam Separator to include the waste handling and disposal.
