Halaman CetakMounting the Filter Cartridge
The cartridge is protected in shipping by two port plugs with O-ring seals.
In addition, two aluminum cups limit the exposure of adsorbent during
assembly, until they are pierced as the cartridge is mounted. Exposure to
air for several minutes during filter installation or change will not damage
the adsorbent.
1. Remove the two port plugs. Save these plugs in case the
cartridge needs to be resealed.
2. Rest the alignment slot of the cartridge on the bottom support
rod of the manifold, and slide it forward until the two ports of
the manifold slide into the sockets of the cartridge. Be careful
to point the check valve needles into the port holes so that
they do not scratch the back of the filter.
3. Push the cartridge forward, engage the clamping screw and
tighten thoroughly.
4. Leak check the fittings.
If you are using hydrogen or hazardous gas, additional special
procedures may be called for. Consult your company's safety
procedures.
5. The filter cartridge is shipped full of helium, but the gas lines
should still be purged with a gas flow for at least several hours
after the initial installation. Moisture levels downstream of the
instrument may continue to improve for several days.
