MAINTENANCE
The SCANMAX 25 contains no user serviceable parts other than lamps and fuses. For reasons of safety
maintenance of the unit should be undertaken by a trained engineer at least once a year during which the
security, integrity and levels of all components should be checked. A radiation leakage check should be
carried out using a calibrated radiation level monitor. Please contact your service representative or

Line Grounding and Regulation
Regulation
When the unit is energised, the line voltage should drop no more than 5% at the wall outlet. Any further
drop indicates that your AC power source needs to be upgraded.
Grounding
A three pin plug must be used with a suitable earth or frame ground. If this ground is not at actual earth
potential a shock hazard can exist. For this reason it should be checked and if possible, outlets with ground
fault interruption should be used.
Warning
Always disconnect the power cable when working on the tube head or controller. Line voltage can be
present at the controller when the key switch is not activated.
Fuse Replacement
Below the mains input socket for the power cord at the rear of the unit is a fuse holder. It is covered by a
rectangular piece of black plastic which is part of the holder. Pull outward on this holder until the fuse is
exposed. Replace with a 15 amp, 230V, 2 AG style Slow Blow fuse. An extra location is provided where
a spare fuse can be kept if needed. If the fuse blows repeatedly, call your service representative.
