Drying Out the Steam Generator of Test Gas Before Shipping
Before shutting down the instrument for long term storage or repair the Steam Generator must be ..... to
prevent any corrosion from occurring during storage or transport.
To prepare the Humidifier for storage or transport follow the procedure below:
Advance all active tests to the Idle state.
Open the cover on the front of the instrument to access the Drain Port and Drain Screw. For
more information see Figure 6-1 and Table 6.1 for the location of the drain port and screw.
While holding a container under the drain port, open the drain screw for the humidifier.
The pressure of the Carrier gas will force all of the water out of the humidifier.
After the humidifier has been drained allow gas to vent out the drain port until all residual
water that is visible has been removed.
Tighten the drain screw.
Changing the Desiccant
The desiccant chamber is located in-line between the regulator tee assembly and the nitrogen tank. Change
the desiccant whenever the blue indicator starts to turn pink. Refer to Figure 8-2 and follow the directions
below to change the desiccant:
Warning!
The desiccant chamber contains high pressure and will cause personal injury if
the nitrogen gas supply is not turned OFF before detaching the gas lines.
