Ensure that the Head has cooled sufficiently before removing the old modelling
lamp from the holder.

Ensure a replacement modelling lamp of the same voltage as the supply (230 V) is
used.

Discard the old modelling lamp safely using the packaging from the new lamp.
Circuit Protection

Circuit protection for the modelling lamp is provided by means of a 20 mm fuse
mounted on the rear of the Head. The fuse is rated at 5 Amp and should never be
replaced with a fuse of a different type or rating.
Flash Tube Replacement
z
A user replaceable flash tube assembly is available - Part No. BW-1873.
NOTE: Flash tubes are very delicate. Handle the assembly carefully and do not
bend the mounting legs close to the glass.
z
ALWAYS switch ‘OFF’ the Pack and remove the connector to isolate the Head
before replacing the flash tube.
z
The flash tube assembly can become very hot in use. Always allow time to cool
before handling.
z
Unwind the twisted trigger wire from the flash tube support.
z
Carefully pull the flash tube assembly away from the Flash Head.
z
To replace the flash tube, insert the two brass sockets through the two large off-
centre holes in the reflector and locate onto the plugs within the Flash Head body.
z
Press down evenly until both plugs are fully engaged. Wrap the trigger wire
around the flash tube support, ensuring that the wire does not touch the reflector.
z
Discard the old flash tube safely using the packaging from the new tube.
Fitting / Replacing Cover Glass
z
ALWAYS switch ‘OFF’ the Pack and remove the connector to isolate the Head
before fitting or replacing the protective cover glass.
z
The cover glass can become very hot in use. Always allow time to cool before
handling.
z
To fit the cover glass (Fig. 2), carefully slide it into two of the retaining clips in the
reflector. Pull the third clip outwards and clip into place over the glass to retain it
in place. Centralise the glass disc in the reflector.
z
To remove the cover glass, carefully pull one of the retaining clips away from the
glass, lift the glass over the remaining clips and slide out.
Flash Power Selection/Indication
z
By using the four Flash Head sockets and associated controls provided on the
1200 / 2400 Packs, many asymmetric and symmetric combinations of flash power
are available from one Flash Head through to four Flash Heads.
