INTRODUCTION

Please ensure you are familiar with the operating instructions prior to commissioning your
equipment. Damage which may arise from incorrect siting or installation is not covered by our
guarantee.
In order to simplify any future requests for spare parts or further information about your ANAESTIVAC unit, we
advise you to copy onto this page the specifications written on the plates fixed to the unit, as soon as you
receive your machine.

DESCRIPTION

The ANAESTIVAC unit removes anaesthetic gases that have not been absorbed or have been rejected by the
patient away from the operating theatre.
The system is centralised and can be connected to several wall-mounted evacuation ports. Gases that have not
been absorbed or have been rejected by the patient are diluted in air and removed by a vacuum created by a
side channel turbine before being discharged outside the building by exhaust ducting. A vacuum relief valve
controls the vacuum level and the output to each wall-mounted port.
The ANAESTIVAC 1 unit consists of a turbine and a control unit.
The ANAESTIVAC 2 unit consists of two turbines: a primary turbine and an auxiliary.

2.1. Side channel turbine

A side channel turbine consists of an impeller connected directly to an electric motor.
The impeller turns at high speed, compressing the air and creating negative pressure at the intake and
overpressure at the exhaust end. The compression that is generated is dry and oil-free. The turbine is cooled by
air blown by the electric motor and by air passes through the turbine. The bearings are lifetime lubricated and
the turbine has been designed to provide continuous operation.

The turbine's suction and exhaust must not be blocked as this may cause excessive
overheating and possibly result in irreparable damage.
Each turbine is fitted with the following:
 At the suction: a vacuum-resistant hose and a check valve (on the ANAESTIVAC 2 model only),
 At the exhaust: a temperature breaker to check the temperature and prevent the turbine from overheating,
a lowest-level drip pot and a heat-resistant hose.

2.2. The automatic vacuum relief valve

According to the vacuum in the network and to a pressure instruction, the valve will open or be closed more or
less in order to fix its position by admitting air in the network to respect the pressure instruction.
The value of pressure instruction is adjusted in the automated system.
It also means that the turbine is guaranteed not to operate if the intake is closed, and also reduces the risk of
the turbine overheating. The automatic vacuum relief valve is equipped with a silencer filter.
If the valve is blocked, it may disturb the operation of the plant.
The set point adjustment must be carried out by qualified personnel.

2.3. Lowest-level drip pot

A lowest-level drip pot has been included to collect condensation that may build up in the exhaust tower. A
shutoff valve is fitted so that the drip pot can be removed safely.

2.4. The isolating non-return valve

The isolating non-return valve is a flapper valve.
With the stop turbines, the non-return valve isolates the network from the station.

2.5. The control panel

2.5.1. ANAESTIVAC 1 panel
Overview
1. On/Off switch:
"Off" position: the turbine is switched off.
"On" position: the turbine will run according to the position of the
auto/manual switch or the pressure level in the system.
2. Auto/Manual switch:
"Auto" position: the pressure level in the system determines when the
turbine starts.
"Manual" position: force starts the turbine.
3. Master switch: cuts the electricity supply to the station.
4. Green "power on" light: comes on when power is being supplied to the switch box.
5. Green "operating" light: comes on when the turbine is operating in either manual or automatic mode.
6. Orange "malfunction" light: comes on if one of the following situations occurs:
 The current to the turbine has been cut,
 The temperature at the turbine exhaust is unusually high and has triggered the temperature breaker.
This fault triggers the malfunction light if it lasts for at least 30 seconds.
 The pressure has not reached the low-pressure alarm setting after the turbine has been started (see § 2.5.3
for setting information on the MILLENIUM system),
