Preinstallation Requirements
2. If non-rigid piping leads from the air source , mount the filter on a
ring stand or on the wall. Clamp the filter to a ring stand, or use the
supplied mounting brackets (see Figure 2-1) to mount the filter
to the wall. Attach the brackets to the assembled filter with the
mounting screws, then attach the brackets to the wall. The air flow
arrow
must point toward the ultracentrifuge. Add hose clamps to
the plain high-pressure hose. Clamp one end of the hose to the
barb fitting of the filter inlet and one end to the air source.
If rigid piping (standard
1
/
4
-in. pipe thread) leads from the air
source , the filter can be free-standing. Remove the barb fitting
from the filter inlet to the air source. The air flow arrow must point
toward the ultracentrifuge.
3. Connect the quick-disconnect hose to the fitting at the rear of the
instrument. Place a beaker or other container under the filter to
collect water and oil.
If the air source does not supply sufficient air pressure to close the
filter’s automatic drain valve you will hear air escaping from the
filter. Routine operation at 30 psig (207 kPa) on the instrument
PRESSURE gauge requires 290 kPa (42 psig) air pressure supplied to
the filter.
TIME-DELAY SETTING CHECK
The time-delay knob (on the ultracentrifuge bottom plate) is factory
set for a 2-minute delay period. Make sure that the knob is still set at
about 120 seconds (or 3.5 on older instruments).
LEVELING THE AIRFUGE
The Airfuge must be leveled before use.
1. Place the supplied liquid level on the center of the stator.
2. Adjust the instrument front feet until the bubble of the level is
centered.
