Step 4: Remove the side cover panels by loosening the two screws on the top

fold. On the Hallett 13, the reflector is attached to the cover panel – see Figure

4A. On the Hallett 30, the reflectors are held in place by a U-clip and pins. First

remove the U-clip from both sides, the remove the back reflector by gently

pushing the tab out from the alignment pins. To remove the front reflector, the UV

sensor can be removed. If the left lamp is removed, the front reflector can be

manipulated out leaving UV sensor in place.

Step 5: Examine the quartz sleeve both inside and out. If it is clean, no

disassembly is required. Replace the reflectors &/or side panels, lamps and

covers. Plug in the unit and operate as normal. If the quartz sleeve is dirty on the

outside, proceed to wipe it down with a clean lint-free cloth and rubbing alcohol to

remove the dirt. If the quartz sleeve is dirty on the inside, proceed with in-place

cleaning or disassembly.

Caution: The quartz sleeve can break or chip if mishandled. Always handle it

with care and keep it in a safe place if it is removed from the unit. Do not strike

the quartz sleeve with any tool, since even the smallest chip can cause it to

break under pressure.
