5.5.7 Humidier Assembly Repairs
A design change was made to the humidier assembly to make it easier to remove the screws during
disassembly. Units shipped since about March 2002 have this revised design. The earlier design can be
identied by the button head cap screws used in the assembly. The later design uses Phillips head screws to
make disassembly easier.
When working on the earlier design if you have diculty with disassembly you may wish to replace the
entire humidier assembly with the later design 6600-0245-850 . When disassembling the older design, we
recommend that you replace the old screws with the new screws listed below. You may also require the other
parts listed below if they are damaged during disassembly. Refer to the Tips section 5.5.7.1.
The reservoir switch button was also redesigned to prevent it from jamming in the closed position. You should
also replace this button when working on an old style humidier.

5.5.7.1 Tips for Repairing the Humidier Assembly on an Old Style Unit
Some of the hex head screws may be dicult to remove. To minimize the chances of stripping the heads, be
sure that the 1.5 mm Allen key you are using is not worn, and is not a ball head style. If you strip the heads,
you may need to drill them out. If you drill out the heads, you may need to replace the ramp block and/or the
heater mount if you have diculty in removing the body of the screw.
