Stampa la paginaMounting 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 of 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 is to be returned in an
exchange after the cartridge has been consumed.
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.
