INSTALLATION
Installation example:
Aethalometer AE33, Sample Stream Dryer, cyclone and MET station
Sample Stream Dryer, Cyclone, MET station - OPTIONAL
Any water intake may damage the instrument.
Damage due to water intake is not covered by the warranty!
1) Remove red protective caps from the
instrument.
2) Attach the sample inlet line using
fittings and adapters. Avoid sharp bends.
3) Switch the instrument on (make sure
to switch on TWO switches, one on rear panel,
one behind front door).
4) Use the size-selective PM2.5 cyclone inlet to exclude
dust and large particles. Clean the cyclone periodically!
5) Use the Sample Stream Dryer especially in cases of
high indoor ambient humidity.
6) Avoid direct discharge of air-conditioner over
sample lines, or insulate them. (This may cause
water condensation in the tubing).
7) Install insect screen/water trap (provided
with the instrument) close to the rear of the instrument.
The cup must be oriented downwards.
The instrument should preferably be installed indoors. If outdoors, it must be protected from the
weather (sun, rain, wind). It should be operated at ambient temperature from 10 to 40°C. If it is
installed in a small enclosure, this must be ventilated by a fan. Avoid placing the instrument or its
sampling lines in the discharge from air-conditioners.

Check sample inlet flow
Inspect sample line tubing
Inspect/clean size selective inlet/cyclone/insect screen
Verify time and date
Inspect/clean optical chamber
Validate/calibrate flow, perform leakage test
Perform Clean Air/Stability check test
Perform ND test
Lubricate optical chamber sliders
Calibrate filter tape optical sensors
Install new filter tape roll As needed
Change cartridge filter As needed
Filter tape exchange
1. STOP the measurements, open the front door.
2. Loosen the thumb screws and remove the transparent plastic covers from both the left-hand and the right-hand side
spool.
3. Using thumb and fingers on both sides of the optical chamber, lift the chamber upwards against its springs and lock it in
place by pushing the metal latch. Remove the used tape from both axles.
4. Take the new filter tape and place it on the left axis. Take note of the metal spring leaf which stabilizes the top surface of
the roll. Take the other cardboard spool and attach the end of the filter to it using adhesive tape. Place the empty on the
right spool axis.
5. Make sure that the tape is fed beneath both the left and the right guide posts, and passes under the optical chamber.
Release the optical chamber by lifting up with thumbs and fingers on both sides.
6. Replace both transparent plastic covers. Tighten the thumb screws by hand only. Check that the left spool can turn
freely. Make sure that the right spool is firmly clamped to its axis: test by gently pulling the tape, and make sure the spool
center does not move.
*Go to „OPERATION-ADVANCED“ screen, press „Change Tape“ button and follow the instructions on the screen
or follow step-by-step procedure described below.

Cleaning the optical chamber
1. STOP the instrument, SHUT DOWN and switch off the power.
2. Using thumb and fingers on both sides of the optical chamber, lift the chamber upwards against its springs. When the
chamber is fully raised, lock it in place by pushing in the metal latch.
3. Find the release button on the front of the chamber. While pressing the release button upward, grasp the lower portion of the
optical head and turn it clockwise so the front of the chamber moves to the left.
4. The lower portion of the optical head consists of a translucent block. Clean all surfaces with ethanol. Put a few drops of
ethanol in the openings and remove any dust or debris by using soft cotton swabs.
5. Use compressed air to remove any debris (fibres) from the openings. No material should be left on/in the openings.
6. To re-install the optical head, first align the notched marker to the left of center; push the optical head upwards to engage the
three bayonet fittings; and turn counter-clockwise (so the front of the chamber moves to the right).
7. Using thumb and fingers on both sides of the optical chamber, lift the chamber upwards. The locking latch will automatically
release. Allow the chamber to return down to the tape.
