When using this appliance, always exercise basic safety precautions, including the following:
•Use this appliance only for its intended purpose as described in this Use and Care book.
•This instrument must be properly installed in accordance with the Installation Instructions before it is used.
•Never unplug your instrument by pulling on the power cord.
•Always grip plug firmly and pull straight out from outlet.
•Repair or replace immediately all electric service cords that have become frayed or otherwise damaged. Do not
use cord that shows cracks or abrasion damage along its length or at either the plug or connector end.
•When moving your instrument away from wall, be careful not to roll over or damage the power cord.
•Unplug your instrument:
A. Before making any repair.
Note: We strongly recommend that any servicing be performed by a qualified individual.
B. Before cleaning.

•Do not operate your instrument in the presence of explosive fumes.
When a standard two-prong wall outlet is encountered, it is your personal responsibility and obligation to have it
replaced with a properly grounded three-prong wall outlet.
Warning
Fire or electric shock hazard, do not expose this product to rain or moisture.
This unit contains dangerous voltages. NEVER remove cover unless qualified to do so
CAUTION DURING INSTALLATION
CAUTION
This unit must be grounded.
The power cord set provided is of the pattern often found in the market area, although
this is by no means universal, but many other patterns are used around the world.
If the plug is not compatible with the socket outlet available, it will be necessary to
obtain a suitable alternative cord set with the correct colour cables connection. The
mains lead coloured green-and yellow must be connected to the ground terminal on the
new plug which is marked with the letter or the earth symbol ⊥or coloured green-and-
yellow.
CAUTION
Before connecting the instrument to a power supply check that the voltage and
frequency details shown on the rear identification label are compatible with your main
supply.
N.B. The equipment must only be connected to a protectively grounded mains supply.
In the event of any uncertainty it is recommended that a qualified electrician be
consulted.
CAUTION
If using a maine supply without a protective earth. Before plugging in the unit, the
ground terminal close to the mains cable on the rear of the apparatus, must be connected
via a 2,5 mm2stranded wire to a safe earth. This work must be done by an authorised
electrician.
Prior to operation always ensure that the ventilation grids of the instrument are not
obstructed and that it is not positioned directly against a wall.

1. INTRODUCTION
The new “PYRAMID” flowcheck is a new easy-to-use, battery operated system that is applied to calibrate all the air
samplers of the “SAS” family.
This instrument is composed of two separate units, a fan and a flowmeter. The perfect balanced fan has a special
rubidium-made bearings that generate an electromagnetic field proportional to the fan speed. The flowmeter measures
this electromagnetic field and then calculates the exact air flow that is passing through the fan.
The “Pyramid” flowcheck system can display the airflow either in litres per minutes (L) or cubic feet per minute (CF).
The precision of the measured value is for “SAS Super 100” air sampler +/- 3 litres, for “SAS Super 180” air sampler
+/- 4 litres.
The internal battery life is approximately 3 years under normal operative conditions.
2. TECHNICAL SPECIFICATIONS
Weight:890 grams
Measurement range: 70-200 litres per minute
Suggested operational temperature: +20°C (+/- 2°C)
Power supply: 3V type CR2032 lithium battery. The normal battery life is 30.000 measurements of 60 seconds
Reading: The LCD display can show the results in litres per minutes (L) or cubic feet per minute (CFM).

3. COMPONENTS OF THE “PYRAMID” SYSTEM
The “Pyramid” system consists of 4 separate parts:
(a) the anemometer
(b) the flow sensor with LCD display
(c) the vertical wind tunnel
(d) the Instruction Manual with record documentation
It is recommended that this scientific system is treated with care and attention in order to maintain its precision.
4. PRELIMINARY INSPECTION
4 The apparatus is subject to specific working tests before shipping and it is carefully packed to avoid possible damage
during transit. However, a visible check should be carried out as soon as possible to determine any transit damage. This
must be reported immediately. The following procedures should be followed to check that the unit is functioning
correctly.

International pbi S.p.A Instruction Manual 29/08/05 Rev. 16
5. INSTALLATION
Anemometer installation
1. Screw the impeller anemometer (a) on top of the aluminium vertical wind tunnel.
Flow sensor installation
2. Fix the flow sensor with LCD display (b) on side of the aluminium vertical wind tunnel.
Vertical wind tunnel installation
3. The battery pack of the “SAS” air sampler instrument to be checked must be charged for at least 14 hours before the
test (3.5 hours if fast battery charger is used).
4. The “SAS” air sampler should be positioned in vertical position in a quiet place on a strong surface. Avoid current of
air around the instrument.
5. Program 1000 litres of air on the “SAS” air sampler and switch it on.
6. Position the “Pyramid” system (c) on top of the SAS air sampler.
7. Switch on the “Pyramid” system by briefly pressing the switch button of the flow sensor. The software version will
appear on the LCD display first, after which the instrument moves into the mode for measuring the current air flow
(litres per minute or cubic feet per minute). The measuring time is approximately 30 seconds to obtain a stable data
reading.
Unit of measurement choice
8. The LCD display switches to the converse version (L/minute or cubic meter per minute) by repeated pressing of the
push button.
Switch off of the unit
9. Hold the push button pressed down until the unit switches off.

6. OPERATIONS
The “SAS” air sampler should be positioned in vertical position in a quiet place on a strong surface. Avoid current of air
around the instrument.
2. Insert a Contact plate (RODAC plate) into the aspirating chamber of the air sampler and screw the aspirating head.
3. Program 1000 litres of air on the “SAS” air sampler and switch it on.
4. Position the “Pyramid” system (c) on top of the SAS air sampler.
5. Switch on the “Pyramid” system by briefly pressing the switch button of the flow sensor. The software version will
appear on the LCD display first, after which the instrument moves into the mode for measuring the current air flow
(litres per minute or cubic feet per minute). The measuring time is approximately 30 seconds to obtain a stable data
reading.
6. The LCD display switches to the converse version (L/minute or cubic meter per minute) by repeated pressing of the
push button.
7. Hold the push button pressed down until the unit switches off.
8. Record the lower and higher values on the record paper.
9. Repeat the operation from 3 to 6 ten times. Record the values of each cycle on the record paper and calculate the
average.
7. MAINTENANCE
In order to maintain its precision, it is recommended that the system is carefully treated.
The system doesn’t require special care and maintenance procedure. Clean the outside surface with a normal cloth.
Do not subject the system to sudden shock.
Battery replacement
It is suggested that the lithium battery 3V type CR2032 is replaced by servicing people or watch dealer.
(a). Unscrew the six screws of the metal back.
(b). Unscrew the screw of the battery cover.
(c). Remove the cover and extract the lithium battery.
(d). Put in the new battery observing the polarity (+ upwards). Screw back the battery cover. Make sure that the tiny
tongue in the centre of the top is raised so that it touches the metal back.
(e). Before refitting the metal back cover, make sure that the seal is clean and securely positioned in its slot.
(f) Refit the back and screw its six screws.
