Any possible repairs under guarantee must be carried out at the Zambelli S.R.L. Laboratories, and should any faults be found due to one of the above indicated causes, both the labour and any parts will be invoiced according to the price list, regardless of the date of the delivery note.
1.3INSTRUMENTS EQUIPPED WITH ROTARY PUMP
Please note that the rotary pumps installed in some Zambelli’s sampling lines (see technical specifications) require a periodic revision, in fact they must be reviewed every 5000 hours or 6 / 7 months of use. We recommend to program with Zambelli technical assistance a periodic maintenance in order to avoid not under warranty unpleasant and machine failures.
1.4PROBES AND ACCESSORIES FOR STACKS ( GRAPHITE GREASE )
When you sampling in stack the first components to be exposed to heat are the probes and accessories in metal material, in this regard, it recalls the importance of using the "graphite grease " to lubricate the metal threads, so as to avoid seize up due to heat expansion
1.5warnings
- Check periodically that the air inlet and outlet of the instrument are not blocked..
- The instrumentation provided with gas-meter must never be reversed even during transport or storage.
- Connect the instrumentation to electricity line only after checking the correct compatibility, compared to what it says on the label of the instrumentation.
- Verify that your plant has the ground earth linking.
- Make sure you have made all the electrical and pneumatic connections correctly.
- We recommend to download the memory at the end of each set of samplings.

2introduCTION
Zambelli S.r.l. offers a new sequential system for ambient for the sampling of total dust (TSP), PM 10and PM 2,5.
The system allows to sample 16 times sequently and it is made of a new compact cabinet entirely in aluminium (or by request available in other materials) thermoventilatedwhere the filter change is automatic and where accessories could be placed, the cabinet is divided into 2 parts so to have it lighter and easy to transport: control unit (upper side) and pump (lower side).
Using the sample heads conform to European Norm EN 12341 (2,3 m3/h)the sequential system is conform to D.L. n ° 60 of the 02.04.2002.
The sequential system conforms to existing norms in regards to electric safety ( CE )
3BASIC INSTRUCTIONS
3.1COMMAND PANEL
The system, protected by a sturdy door, has a control panel that allows the management of the system and the automatic movement of the filters. Youcan use an optional module to manage the sensorsof relative humidity, of the speed and wind direction and of also a system that regulate and keep constant the flow sampling.
Using the heads for sampling PM 10 and PM 2.5 in accordance with European standard EN 12341 (flow rate 2.3 m3 / h), or alternatively, the sampling heads PM 2.5 and PM 10, conform to USEPA (flow1 m3 / h), the detection of ambient temperature and barometric pressure allow to calculate and update in real time the samplingflow, so to maintain constant the air speed at the entrance point of the fractionated PM 10 or PM 2.5. This regulation system grants higher accuracy in the collection of particles with the use of PM 10 - PM 2.5).
The data of the planning and of the samples managed by the system are stored and / or printed.
The memory capacity can store more than 20 samples, considering that the data of asamplingare made of the settled data and of the individual samples. For more safety reason, the data are protected against the accidental cancellation.
The stored data can be downloaded to a Personal Computer and/or printed even during or at the end of the samplingperiod. With the storage of the data it is possible to continue with the execution of the sampling even in case of error of the printer.
The software features of the sampler are described in the following paragraphs.
Parameters list:
- Volumic flow at the beginning of the sample
- Average of the volumic flow in the sampling period
- Variation coefficient CV of the volumic flow in the sampling period
- Indicator of exceeding for more than 5 minutesof the limit of the 10% of the settled flow
- Total volume sampled
- Ambient temperature
- Average, minimum and maximum of the ambient temperature in the sampling period
- Atmospheric pressure
- Average, minimum and maximum of the ambient pressure in the sampling period
- Down pressure on the filtering device during the sampling
- Average, minimum, maximum down pressure in the sampling period
- Temperature close to the filtering device
- Indicator of the exceeding maximum allowed limit (5 °C) in the difference between the temperature close to the filtering device and ambient temperature for more than 60 minutes
- Maximum differential between temperature close to the filtering device and ambient temperature with date and time of the event

3.5HANDLING AUTOMATIC FILTERS (INTEGRATED)
The automatic mover of the filters (built into the system) allows you to sample up to 16 filters in sequence. The system guarantees the protection of the white filter and the filter exposed to any external pollution. Thefilter holder prevents the manipulation on-site of the filtration membranes.

3.6CASSETTE FILTERS
To run the samples you must use the "cassette filters”. This system of "filter preparation” has the advantage of avoiding the manipulation of the filter in the place where it has been executed the sampling. The CONTROLLER 16 is equipped with 2 cartridge filters, one for the "white"filters and the other for the sampled filters. The loader of the cassettefilter is a system that facilitates the transport and the storage of the filters. It is able to contain up to 16 filter cassettes. Inside each cassette filter it can be placed membranes of different types depending on the substance that has to be determinated.

HHousing of the loaders in the CONTROLLER 16
PRELIMINAR OPERATIONS TO EXECUTE ON THE CASSETTE FILTERS:
The preparation (conditioning) of the filters must be performed without the cassette filter.
Always check the precise fitting of the cassette filters (Sequence: Membrane - White Ring - closure Ring of the cassette filter) and verify that they are blocked and without dents.
In the case of use of membranes in Teflon with ring reinforcement it should not be mounted the white cassette filter. If you use membranes in cellulose acetate it is necessary to mount a pre-filter to increase the total thickness. Use membranes with maximum thick of 475 micron (please contact before Zambelli for the use of higher thickness membranes).
Do not write and do not apply labels on the sides of the cassette filter. Always check the exact quantity of the cassette filters in the left loader (white filters) depending on the number of samples to execute.

3.9installaTION OF THE RAMP SUPPORT
Picture 9
After installing the cab and after having connected all electrical and pneumatic connections of the sequential system, you can proceed with the placement of the ramp support (pole).
- Must be mounted past the flange wall (A) on the top of the cabin.
- Before inserting the sampling head in the ramp lubricate the OR with silicone oil.
- Before inserting the ramp in CONTROLLER 16lubricate the OR with silicone oil
Repeat steps lubrication of OR at the beginning of each set of samplings.
BPlace on top of the ramp support (C) the sampling head depending on the type of determination to be performed
DUsing a compass key to tighten or unscrew the nut, insert the ramp in the flange (A) until it reaches the CONTROLLER in order to reach the axis of the push-filter (E), after which put it in the push filter and verify that it gets the lower position of the push-filter; subsequently lift it at least 5 mm (F). Before starting a series of samplings, verify that the OR of the pale is inserted even when the push-filter goes down to the filter cassette. For this verification, proceed with the manual loading of the filter, through the useof the dedicated button on the CONTROLLER 16
GSelect tha sampling flow:
- In conformity to the “US EPA” norm ( 16.7 l/min )
- In conformity to the “UNI EN 12341” ( 38.3 l/min )
