Modelling Lamp Replacement and Use

The F200/400 units are fitted with high temperature ES safety
lamp sockets which are designed to reduce the possibility of
injury due to electrical shock.
The following precautions are still required when fitting a lamp:
1. The lamp rating must be a maximum of 275Watt 220-250V
2. Double-envelope, 230/250W, Halostar-type ES lamps are
recommended.
3. Standard 150W and 275W Photoflood ES lamps can also
be used.
4. Do not use single envelope, open QH lamps under any
circumstances.
5. Turn the unit off before fitting a lamp.
6. Turn the unit off and allow the lamp to cool before
replacing it.
7. Keep fingers away from the socket or the lamp thread
when fitting the lamp.
8. Avoid touching the flash-tube with the lamp. Note that
the flash-tube is not user-replaceable; flash-tube
replacement must be carried out by qualified engineers
only.
9. It may be necessary to replace the unit's fuse if a lamp
has broken; refer to fuse replacement instructions.
10. Most lamps are fragile and can easily break. Take care
when fitting a lamp.
11. The ES screw socket may require the lamp to be fully
screwed down in order to make contact. If a new lamp
fails to light, check that it is fully screwed down.
12. Take care not to damage the lamp when fitting
reflectors and accessories.
13. Lamp filaments are fragile, particularly when hot. Avoid
moving or jarring the unit when the lamp is on.
14. Anything placed in front of the lamp must be fire-
resistant. Soft-box material must be suitable for the
purpose.
15. The lamp envelope and the surrounding metal will
become hot during use.
16. Avoid fitting accessories that restrict the flow of air
around the lamp and flash-tube.
17. The unit is fitted with a comprehensive system of thermal
safety cut-outs. These cut-outs will shut the flash circuit
down in the event of overheating. The overheat condition
will be indicated by the Ready light being extinguished even
when the Power switch is illuminated. The lamp will still be
on if the lamp Full switch is on. If the overheat condition is
indicated, switch the unit off and leave it for 30 minutes. If
the overheat condition persists, refer the unit to a qualified
engineer to be repaired.
