The only repairs which can be performed by the user are the replacement of fuses and lamps in
the operating unit. Fuses and incandescent lamps for replacement are provided in the service kit. The
operating unit need not be opened for replacement.
WARNING
Before carrying out any repair or maintenance work, always disconnect the de-
vice from the power supply by pulling the mains plug!
For exchanging fuses, open the bayonet locks of the fuse holders on the front panel of the unit
with a screwdriver. Defective fuses may be exchanged exclusively against fuses of the same type.
For exchanging incandescent lamps, use the lamp puller provided in the service kit. Get hold of
cap with lamp puller and pull vertically upwards. Exchange lamp. Position pressure cap in place (do
not turn!), and press it in.
It is principally forbidden to carry out repairs on the high-voltage unit. In case of oil leakage, me-
chanical damage on the enclosure or other visible defects on the high-voltage device, the test may

If the S-36 VLF is defective, you have to send the complete device, that is, the high-voltage unit,
