CHANGING THE FLUORESCENT TUBE
Ensure the transformer is disconnected from the power supply before
opening the door and cutting the two ties securing the lamp to its retain-
ing clips. Carefully pull the lamp from the retaining clips then hold the clear
plastic protective outer tube firmly and ease off the plastic end cover from
the nonwired end. (This may take a little persuasion and perseverance).
Once the end cover has been removed, hold the end cover at the opposite
end (the cable input end), and pull off the outer protective clear plastic
tube. The fluorescent tube is now fully revealed.
Pull off the end connector, which secures a wire to one of the pins, taking
care not to distort the aluminium reflector. Then pull off the wire secured
by a plastic sheath to one of the pins at the cable input end.
Assemble in reverse order, ensuring the wires are correctly held by the plas-
tic sheath at one end and the end connector at the other, with the reflector
correctly in position.
Re-fit the assembly into its retaining clips and test its operation by plugging
the transformer into the mains.
