Maintenance

Introduction

The Anaesthetic Gas Scavenging (AGS) disposal system is designed to operate with the minimum of
maintenance, however minor routine maintenance operations are necessary to ensure total system reliability.
Maintenance Engineers must fully understand the system and be conversant with the information contained
in this manual. Correct tools, clean and serviceable must be available and the necessary spare parts obtained
before commencing any maintenance operation.

1. Obtain a work permit (if applicable) before commencing any work on the AGS disposal system.
2. Before commencing any work on the exhauster unit, ensure that the isolating switch is OFF. If

the maintenance period is prolonged, padlock the isolating switch in the OFF position.

Routine maintenance

BeaconMedaes 

can provide a planned preventive maintenance contract suitably adapted to meet customer

requirements. The following routine maintenance operations are the recommended minimum.

The longer interval checks must also include the shorter interval checks.

Weekly inspection

The weekly inspection consists of the following operations:

1.

Exhauster unit:

Visually inspect the exhauster unit and remove any accumulated dust from the casing surrounding area.
Ensure that the motor air cooling inlet and exhaust are free from obstruction.
Run the exhauster unit and ensure that its operation is smooth and free from any unusual noise levels.
Drain and clean the drain assembly as necessary.

2.

Flow regulating valves:

Ensure that the air inlet to flow regulating valves are free from obstruction.

Monthly inspection

Visually inspect the flow regulating valves for security and freedom from damage. Ensure that the silencer
air inlet is not obstructed.

Quarterly inspection

The quarterly inspection consists of the following operations:

1.

Exhauster unit:

Check and tighten exhauster unit mounting bolts.
Check control of the exhauster unit by operating the isolating switch, HAND/OFF/AUTO switch and all
remote start switches. Ensure that the indicator lights on the remote switch panels operate correctly.
Check exhauster unit operates until all remote switches are selected OFF. With a Duplex installation both
exhauster units and the automatic change-over facility should be functionally checked.

To simulate a duty pump failure, the duty selector switch is used to designate an exhauster unit as
“Duty”. Both isolator switches are selected ON and both HAND/OFF/AUTO switches are selected to
AUTO. The “Duty” exhauster unit is operated by selecting a remote ON/OFF switch to ON. A
simulated failure is produced by selecting the “Duty” exhauster unit HAND/OFF/AUTO switch to OFF.
The Standby exhauster unit should automatically operate.
