Cartridge Regeneration
5
Turn the power switch ON and perform the Controlled Venting purge as described in the
Startup section, then begin using the generator.
Note:
For best results, purge the system for one hour to remove any residual oxygen and
moisture from the instrument and piping downstream.
When the desiccant becomes saturated with moisture, the orange indicating color will turn
clear. The expended desiccant cartridge can be regenerated for later use, so long as a mois-
ture proof container is available.
Cold Vacuum Oven -
For best results, place the desiccant cartridge in
a cold vacuum oven
and ramp the temperature at 2°C/minute to 150°C while supplying a vacuum.
Do not exceed
175°C.
Regeneration will be complete in 8 hours.
Conventional Oven -
If only a conventional oven is available, place the cartridge upright
inside the oven to allow the moisture to leave from the top of the cartridge. Apply the following
ramp rate and procedure:
• 2 C/min from room temperature to 90°C ,hold at 90°C for two hours.
• 2 C/min from 90°C to 150°C and hold at 150°C for 24 hours.
• Cool the cartridge in a desiccator or low moisture environment until needed in the hydrogen
generator.
For either method, do not exceed 175°C.
The temperature will not affect the desiccant
performance; however, once the orange beads remain clear, they can no longer be used as
a color indicator and the cartridge must be discharged. Apply a light coat of DI water to the
o-rings prior to inserting the cartridge into the generator plastic housing.
The DI Resin bed cartridge should be rinsed and the Resin bed replaced every 6 months, or
whenever the water quality deteriorates, which is detected by a color change in the Resin bed,
ie, the color changes from a Dark brownish color to a Orange color. If 75% of the Resin bed
has changed color, then the Resin bed should be replaced. No tools are required to change
the Resin bed.
1
Turn the Power Switch to OFF.
2
Lift the top cover lid and unscrew the water reservoir cap. Remove the Resin bed car-
tridge from the Reservoir bottle (see Figure 13).
3
Inspect the replacement Resin Bed Deionizer for damage prior to installation into the
water reservoir. Replace the Reservoir cap after the resin bed has been reinstalled.
4
Refill the unit with deionized water by using either the Autofill or by manually filling the
unit with approximately 2 liters of DI water.
NOTE:
Do not allow the DI Resin bed to dry out; it must be immersed in water to perform.
5
Restart the generator in the same manner found in the Startup section.
Resin Bed Replacement
Fuse Replacement
Occasionally, the fuses in the FID gas station may burn out. The fuses are located in the
power receptacle on the back side of the generator.
Before servicing the fuse, turn the unit
off and disconnect the power cord from both the power supply and the generator power
receptacle.
To access the fuses, use a small screwdriver to remove the fuse holder located in the back of
the unit and in the power receptacle. In the FID Gas station, both the phase and the neutral
are fused separately. As a result of this configuration, both fuses should be checked any time
fuse replacement is warranted. Replace either one or both with the appropriate fuse and re-
assemble.
To maintain the safety and performance integrity of the product, use only the fuse of
the size and type detailed in the Specifications, Parts and Accessories sections of this
bulletin.
