10 - Gemini R and Pro | Operation
Changing the Flash Tube
Ensure that the unit is switched off and disconnected from the
AC supply and then wait thirty minutes before touching or
removing the flash tube.
Remove the protective cap and unwind the twisted trigger
wire from the flash tube support.
Gently pull the flash tube assembly out of the unit.
To replace the assembly, hold the flash tube as shown and
taking care to support both legs of the tube, gently but firmly,
push the flash tube into position, and wind the trigger wire
around the flash tube support.
Always replace with the correct flash tube assembly.
Gemini R range: BW2030 (clear) / BW2032 (UV coated)
Gemini Pro range: BW2980 (clear) / BW1079 (UV coated)
Changing the Modelling Lamp
Switch off the Gemini and disconnect from the power supply.
If the unit has been in use, allow a sufficient amount of time
for the lamp to cool.
Unscrew the modelling lamp from the lamp housing and
replace wit hthe correct lamp type.
When changing the modelling lamp on a Gemini 1000Pro or
1500Pro, first remove the protective glass cover over the flash
tube (ensure the glass has cooled sufficiently before touching
if the unit has been in use), then replace the modelling lamp.
When changing the smaller E11 Halogen lamps, ensure not to
touch the glass with your fingers as the oils from your hands
can reduce the life of the lamp.
Changing the Fuse
The modelling and flash circuitry are protected by a single
20mm fuse mounted in the rear panel of the unit.
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 at the rear of the unit.
The fuse draw contains two fuses, the furthest fuse 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.
Transporting Units
When transporting any Bowens units, ensure that all
equipment is carefully packed into appropriate bags and/or
hard shell cases. Make sure all items are securely placed
inside the appropriate baggage to protect from any knocks.
Flash units can become very hot after use. Always wait a
minimum of 30 minutes before packing to allow units to cool
sufficiently.
If a unit is dropped and / or knocked during transport, always
have the unit checked by an authorised Bowens service /
repair centre before using.
Power Cables
Only use Bowens approved mains or battery cables to power
Bowens products. All mains cables must be used as
