7 Maintenance and fault rectification

7.1 Cleaning

Clean the instrument in regular intervals. Note the following points:

Clean the instruments from substance which can influence the

safety function

Take care that the writing remains legible

Clean the adhesive labels and the connection box (version with

pneumatic switching facility) only with water (only slightly moist).

Avoid electrostatic charge on the instrument. Never rub dry when

cleaning.

Warning:

Take note of all safety instructions in this operating instructions

manual when cleaning.

7.2 Maintenance

If the instrument is used properly and if the specified ambient and

operating conditions are maintained, there is no maintenance of

VEGASOURCE 35 required.

Along with the regular inspections of the system, we recommend the

following tests:

Visual check on corrosion of the housing, the weld joints, the outer

parts of the source insert, the lock/locks, the lock washers.

Test of the mobility of the source insert (switching on and off func-

tion)

Judgement of the legibility of all labellings and warning signs.

The hold of the source holder.

Caution:

If you are not sure of the correct function or condition of the instru-

ment, contact immediately the responsible radiation safety officer for

further instructions.
Caution:

Repais or maintenance work exceeding the standard inspection

must only be carried out by the manufacturer, supplier or particularly

authorized persons.

If there are clear traces of corrosion on the source container, the local

dose rate (µSv/h) must be measured in the surroundings. If the rate is

clearly above the values during normal operation, then the area must

be cordoned off and the responsible radiation safety officer informed.
Corroded instruments and lock washers must be exchanged as soon

as possible.

Warning:

Source containers with corroded locking device or source insert must

be replaced immediately.
