GeneralAire®Model 5500 Steam Cylinder Replacement Instructions
The humidifier and the cylinder contain live electrical components and very hot surfaces. All service and maintenance operations must be carried out
by qualified personnel who are aware of the necessary precautions. Before performing any operations on the cylinder, make sure that the humidifier is
disconnected from the power supply. Remove the cylinder from the humidifier only after having drained it completely.
Conductivity
Conductivity measure the amount of minerals in the water; on the new version of the GeneralAire®Model 5500, a cylinder has been designed that can be
used with conductivity levels between 125 and 1250 µS/cm. This simplifies maintenance.
Steam Cylinder Replacement: Model 55 - GFI #7746 (USA); Model GF-55 (Canada)
Measuring Water Conductivity
A water sample should be taken from the humidifier supply connection. The water sample can be tested on site by available portable cup or dip style
testers. Tester Manufacturers: Hanna Instruments, Oakton Instruments, Myron L. Company, Mettler-Toledo, Denver Instrument Company, and Electro-
Chemical Devices, Inc.
