APPENDIX: PRIMING RECIPE INFORMATION

GUIDELINES FOR PRIMING A NEW FILTER
A filter consists of three areas that need to have air
replaced with fluid: upstream of the membrane,
downstream of the membrane, and in the porous
area of the membrane itself. This air needs to be
removed from the filter and vented out of the pump.
Begin the priming sequence with:
• Vent cycles to fill the upstream part of the filter
with fluid, until a solid stream of fluid is seen in
the vent line.
• Purge cycles until solid fluid is again seen in the
vent line. This begins to wet the membrane and
removes the bulk of the air from the filter down-
stream of the membrane.
• Inlet cycles will recirculate the fluid through the
filter and back to the inlet, with a small amount
of vent. This completes the wetting of the mem-
brane without excessive use of chemical.
