Changing lamps
How to replace a lamp:

Open the flash cure by removing the two black caps and unscrewing the M4 bolts and cap
retainers on each side of the lid.
2.
Lift the lid and locate in the hole in the lid. Support the lid with the rod that can be found in
the front of the dryer. Note which cables are attached to the lamp to be changed, loosen the
bolts that secure the wires into the ceramics on either end of the lamp. pull the bolts out of
the ceramic and leave the cables loose.

lamp. Hold it by the ceramics and ease it out of the lamp holders, now remove it from the
dryer.

The lamps are installed in the dryer with tension springs at either end. Make sure that the
replacement lamps are installed in the right orientation.
5.
To install the replacement lamp, gently ease it into the holders. Guide the cables from either
end of the lamp through the reflector. Tighten the wing nuts until the lamp is secure but take
care not to over tighten them.

Place each cable end in the lamp ceramics. Secure them by tightening the screw holding
them into each ceramic.

After any accidental skin contact with the glas or quartz lamp surface the lamp has to be
degreased. To do this, gently clean the lamp with the provided cleaning cloth or other soft
cloth moistened with Denatured Alcohol or Methylated Spirits.

Make sure that the ceramic ends of the lamp do not touch the housing and that the carbon
element is horizontal.

the cap retainers, M4 bolts and black caps.
