Replacing the Flashlamp
(1) Remove the lamp holders on both sides. Straighten the lead wire of the
ashlamp and pull out the lamp holder along the lead wire. Pull out the O-rings
on both sides of the ashlamp in the same way.
(2) Slowly pull out the flashlamp from either side. At this time, straighten the lead
wires so that their terminals will not scratch the reector panel.
<Notes>
- Take care not to blemish the reector surface by terminal of the lead wire.
- Take care not to damage the flashlamp by striking it against the metal
portion of the chamber.
(3) Straighten the lead wires of the new flashlamp and insert them in the upper
chamber.
⇒
Set the polarity of the lamp correctly. Set it so that the terminal of the lead wire
marked in red may be positioned on the + side of the upper chamber. If the
polarity of the lamp is reversed at installation, the service life will be shortened.
Be sure to check the polarity.
(4) Pass the O-ring attached to the ashlamp from the lead wires on both sides and
set each of them in the ashlamp.
⇒
Make sure that the O-ring is not damaged. If the O-ring is damaged, water
leakage will occur. In such a case, replace the O-ring with a new one.
(5) After pushing the O-ring by the lamp holder, install the lamp holders on both
sides in the same way. After making sure that the O-ring is set in the groove,
tighten the bolt.
