Modelling Lamp Fitting

1. Before fitting or removing a modelling lamp, always ensure the power is switched off
and remove the mains cable from the unit.
2. Avoid touching the flashtube and glass envelope of the modelling bulb
with bare fingers as this can leave grease on the glass which can shorten
the life of the bulb.
3. Select the correctly rated modelling bulb for the local mains supply.
4. If a bulb is already fitted carefully unscrew it using a cloth.
5. Remove the new modelling bulb from its packaging by grasping the glass
bulb with a clean tissue or cloth.
6. Continue holding the bulb with the tissue or cloth and carefully screw the
bulb into the holder until it is held firmly. Do not over tighten.

Flashtube Replacement

1. Before fitting or removing a flashtube, always ensure the power is switched off
and remove the mains cable from the unit; also remove the modelling lamp if fitted.
2. Avoid touching the new flashtube with bare fingers as this can leave
grease on the glass which can shorten its life.
3. Carefully unwind the trigger wire from the flashtube support.
4. Grasp the flashtube with a cloth and carefully prise it out of the supporting
connector holes by gently rocking it from side to side.
5. Remove the new flashtube from the packaging.
6. Grasp the new flashtube with a cloth and straighten out the trigger wire.
7. Carefully push the flashtube connectors/legs into the sockets in the flash head
until fully inserted.
8. Wind the trigger wire tail around the top of the flashtube support.
Changing the Fuse
The modelling and flash circuitry are protected by a single 20mm fuse mounted in a draw
next to the mains input.
A fuse may blow when the modelling lamp fails; always check the fuse when replacing a
bulb. A spare fuse is located in the draw underneath the mains connection on the bottom
of the unit. The fuse draw contains two fuses, the furthest inside the draw is the live fuse
and the nearest one is a spare. Never replace the fuse with one of a different rating.
Always switch off the unit and disconnect the power supply before changing a fuse.
