ELECTRICAL WARNING
Always electrically isolate the SA suction unit from the mains power supply before carrying out any
cleaning, maintenance or repairs. Electrical isolation of the SA suction unit is by removal of the
mains power cable from the mains power supply.
Never operate a SA suction unit in the presence of flammable gas such as anaesthetic agents.
This is an Explosion hazard!
Ensure the power cable does not create a trip hazard or is subject to damage.
The suction pumps may only be opened by qualified technical personnel. Electric shock hazard!
Equipotential bonding may be required in some critical treatment areas. This is intended
to minimize any voltage differences between earthed parts of equipment and any other
exposed metal in the room. All conductive metal in an equipotential area is connected to
a common equipotential earth (reference) point.
The SA suction unit has on its back panel (adjacent to the mains power cable) an equipotential earth
point to allow connection to an earth reference point when required. Installation of this connection
must be carried out by a fully qualified engineer. Ref: BS EN 60601-1
