2. INSTALLATION
2A. INSTRUCTIONS AND CHECKS ON DELIVERY
Installation plays an important role for ECOCHEM cupboards, whose use is sometimes critical; therefore they
should always operate under their best conditions.
The fume cupboards ECOCHEM are located on a pallet, wrapped into a stretchable film and placed inside a
multilayer strapped cardboard package.
For a general check, place the unit in its working place, open the package and remove the stretchable film,
then check if the unit has suffered from any dents or scratches due to transportation or incorrect handling.
In case of transportation, packaging and stocking by the user after a first period of use (i.e. Laboratory or
plant change), contact the technical service or the distributor in order to obtain accurate and precise
directions or to ask for the intervention of qualified technicians.
ECOCHEM fume cupboards - with or without packages - must always be sheltered from rain.
2B. INSTALLATION REQUIREMENTS
During installation, the unit shall be protected from draughts and heat sources (radiators, fan convectors) in
order to create the best working conditions.
- The clearance around the work opening shall measure at least XXXX mm.
- The front distance between the work openings of two cupboards used by one single operator shall
measure at least XXXXmm.
- No walls or obstacles should affect the air flow within XXXX mm from the work opening.
- No cupboard shall be installed where it could be disturbed by another equipment and/or unit.
- The distance between the work opening and any air source shall be at least XXXXmm.
- The distance between the front opening and the door or any other entrance way shall be at least

2C. ELECTRICAL/GAS CONNECTION
The electrical connection of the fume cupboard ECOCHEM is carried out by connecting the power cable
located on the upper of the right side of the cabinet to a suitable power point (see technical table). When
the cabinet is connected, the green light on the control panel switches on (see section 4D).
If provided by the laws in force, insert an automatic protection switch (at its maximum power) upstream on
the power input line. The switch shall be fitted with a differential relay with operating current rate not
exceeding 30 mA.
Any instrument with a heat source shall be located at a distance of at least 150 mm from the bottom and
side walls. Moreover we recommend not to use a flame at less than 300 mm from the adsorbing filter.
2D. POSITIONING OF THE CABINET ON THE SUPPORTING TABLE
ECOCHEM cupboards can be supplied with the relevant supporting table, which they have to be fixed to.
After assembling the supporting table (see instructions at section. 14) put the supporting table on a flat non
sloping floor and be sure that all the parts of the cabinet, that can be opened (control board panel and
window) are locked. Then position the cabinet on the table.

3. OPERATION PRINCIPLES
The working process for the ECOCHEM is the following:
- Air is taken from outside through the front opening; the contaminant is removed at work surface level
and is carried upwards into the upper part or head of the fume cupboard, with an air flow.
- inside the fume cupboard head, air goes through a prefilter which cleans the air from particles and
aerosol or mist; then air goes through an activated charcoal filter (standard type and chemisorption
type) where the physical, chemical-physical and chemical reactions to remove the contaminant from
the air flow take place. The air is then exhausted outside the fume cupboard and recirculated in the
environment.

4. OPERATION
4A. SCOPE
The fume cupboards ECOCHEM are designed to protect the operator and the environment from fumes,
vapours and smells produced during routine laboratory operations whenever chemicals, reagents etc. are
used.
Their use is NOT recommended for particular workings which do not belong to laboratory routines, such as
those generating large quantities of evaporated solvents, acid digestions and the use with solvents whose
nature, structure and chemical formula are unknown.
4B. SYSTEM AND PERFORMANCE CONTROLS
The fume cupboards ECOCHEM are fitted with regulator in order to keep the airflow speed constant with the
progressive clogging/saturation of the main activated charcoal filter and prefilter.
The control panel is fitted with various controls, such as:
ECOCHEM-S
- manual regulation for airflow speed
- hours counter monitoring the real operation time of the fume cupboard
ECOCHEM-M
- microprocessor for air speed, prefilter and main filter efficiency automatic control
- alarm devices for low/high airflow speed, device monitoring possible explosive concentrations, motor
fan malfunctioning and gas sensor control
- hours counter monitoring the real operation time of the fume cupboard and the activated charcoal filter

4C. REMOTE SIGNALS (OPTIONAL AVAIBLE FOR ECOCHEM M)
The electronic control board can be improved with an output signal: it is possible to obtain a 12 Vdc output
to connect a LED light or alternatively a Normally Open voltage free contact to be connected to an external
circuit. This signal can be set in three different modes:
Motor ON:
The signal starts when ventilation is turned ON and stops when ventilation is OFF.
Alarm:
That signal is ON in case of any flow alarm and it is OFF when air flow rate is in the correct range.
AIR FLOW OK:
That signal is ON when air flow rate is in the correct range and it is OFF in case of any flow alarm.

6. LIMITATIONS
Conditions for a correct use of the fume cupboard.
We list below the most important conditions and the substances to avoid for a correct use of the fume
cupboard:
- DO NOT use manipulations/reactions generating large quantities of solvents and/or industrial
quantities.
- AVOID operations such as acid digestions, operations with radioactive compounds in potentially
hazardous quantities, avoid the use with substances having an unknown formula, nature and origin.
- DO NOT use the fume cupboard for manipulations/operations if the activated charcoal filter installed is
not adequate.
- DO NOT use the fume cupboard if the pre-filter is clogged and/or the activated charcoal filter is
saturated.
- DO NOT use the fume cupboard if the front side is totally open, since this could create a drastic reduction
in the airflow speed and in efficiency.
- AVOID high concentrations of smokes, for instance in case of an accidental leakage of chemicals, since
this could create a temporary block of the main filter. Therefore, immediately remove/clean the spillage
(preferably by using adsorbent granules). The use of adsorbent papers or fabrics could worsen the
evaporation process. In case of several spillages, it is necessary to remove the filter and replace it with
a new one. The old filter, once stabilized after a few days, can be used again if not saturated.

7. OPERATING PROCEDURES
7A. GENERAL OPERATING INSTRUCTIONS
Before carrying out any type of action, the operator shall check the following conditions:
- That the cabinet power cable is connected to a power point at a suitable voltage and frequency as per
instructions shown on the label stuck near the electric cable
- The fume cupboard can work in an efficient way if the filter installed was correctly selected according to
the type of application.
- Periodically check the efficiency of the activated charcoal filter and pre-filter.
- When you use the fume cupboard, the front door shall ALWAYS be completely lowered in order to obtain
the maximum airflow speed.
- For information purposes, reduced airflow speeds (<0,4 m/s) indicate reduced toxic vapours
containment capacities. Therefore, we recommend to work at speeds higher than 0.5 m/s, except for
the storage of reagents bottles or when low toxicity compounds are handled.
- We recommend to replace the pre-filter each time you replace the activated charcoal filter. A spare filter
should always be kept available, in case of emergency.
7B. FUME CUPBOARD SWITCHING ON
To start the cabinet, proceed as indicated below:
1. turn on the light by pushing the blue button [10]
2. Press the main key I/0 (see section 4D.) and enter the password to switch on the cabinet (5 – 4 – SET).
At first the display shows “CHECK PANEL” and the corresponding control LED’s of the keyboard light up.
Then the message "STAND-BY" is displayed for about 40 seconds and the hour-counter starts operating
3. After 40 seconds of stand-by, the cabinet is ready for work. "STAND-BY" disappears from the screen and
the LAF velocity are displayed
4. Adjust the airflow speed by means of the HIGH/LOW ARROW keys of the keyboard, according to the type
of process to carry out.
7C. FUME CUPBOARD SWITCHING OFF
Once the process is over, carry out the following actions:
1. Remove any waste material from the work chamber.
2. Clean the work surface and the inner chamber walls as described under "Cleaning instructions" (section
7A).
3. If the lamp is on, switch it off by pressing the keyboard key.

8. MAINTENANCE
ATTENTION: Disconnect the fume cupboard from the main power supply before carrying out the
operations described below.
8A. INSTRUCTIONS FOR SIX-MONTH CLEANING (By the User)
- Remove and clean the work surface and the side walls, the bottom and the front door with a diluted
detergent solution. This should be a non-corrosive solution for the fume cupboard structure.
- Control the side walls, the bottom and the front door in order to check if there are corrosive actions and
damage/breakage to the structure.
- Control the hinged doors for corrosion; if necessary adjust the hinge friction by acting on the central
adjusting screw.
- Remove the prefilter/s and filter/s and control the head inside and the fan assembly for correct
operation.
8B. CONTROL AND MONITORING PROCEDURES
The monitoring of the fume cupboard ECOCHEM operating parameters aims at assuring an efficient
operation.
In particular: the use of fume cupboards with clogged prefilter/s implies a reduction in the airflow speed and
therefore a non-removal of the contaminant. Their use with saturated activated charcoal filter/s implies the
non-removal of the contaminant.
With ECOCHEM-M fume cupboards, the microprocessor monitors the airflow speed; therefore there is no
need for the operator to check the prefilter. With ECOCHEM-S fume cupboards, which are not fitted with an
airflow speed control system, the prefilter must be controlled manually every month or every three month,
according to the amount of work carried out, by the user or by a service company with adequate monitoring
devices.
Cupboards like the ECOCHEM-M (fitted with an optional gas detector), a gas detector constantly monitors
the exhaust air and is able to signal possible concentrations of explosive gases.
NOTE: We remind that the smell of some compounds (e.g. H2S or NH3) is very strong. Therefore the presence
of smells does not automatically imply a higher concentration of solvent in the air than that allowed.
AIRFLOW SPEED MEASUREMENT (carried out on a monthly basis by the user)
The airflow speed is measured by means of an anemometer which can be a hot-wire, fan, vane anemometer
or others.
Start the fume cupboard and wait at least 5 minutes to balance the airflow speed.
Minimum three readings should be taken across the working opening; note these data in the "ECOCHEM
monitoring card". If the average airflow is lower than 0.5 m/sec, REPLACE THE PREFILTER/S.

MANUAL MEASUREMENT OF THE CHARCOAL FILTER SATURATION DEGREE (carried out on a monthly or
quarterly basis by the user)
The test is executed by means of a sampling device (Gastec or Draeger or Kittigawa type). Select the sampling
tube for the substances used in the laboratory routine (e.g. alcohol or toluene or trichloroethylene).
Place 6 ml of the selected solvent into a beaker; with a hotplate let it boil for two minutes.
This operation gives a solvent concentration equal to 100-200ppm.
Sample the outlet airstream from the unit, following the instructions of the gas sampling tube supplier.
Read the detected concentration. If higher than TLV, REPLACE THE CHARCOAL FILTER/S. If lower, note the
value read on the "ECOCHEM MONITORING CARD".

PREFILTERS
High performance prefilters are designed to remove particulates from the air stream. The filter material is
based on electrets, which are permanently charged di-electrics. They remove particulates from polluted air
by strong electrostatic forces generated by the fibres of which they are made. The combination of strong
electric charges and open structure provides a filter with high efficiency, low airflow resistance and high
loading capacity.
Prefilter efficiency is equal to 75-85 dust weight arrestance (ASHRAE).

MAIN FILTERS
Three types of filter media are available.
Most of these are impregnated activated charcoal, to provide a higher filter capacity for lower molecular
weight organic compounds and inorganic gases and vapours.
A number of filter efficiency studies have been carried out and all results using single bed filters show
efficiencies very close to 100%.
1. A/C FILTER
The A/C filter is the most widely used filtering the range and is used primarily for solvent fume removal. It is
manufactured from coco-nut shell based activated charcoal of 4 x 8 USS mesh size and surface area up to
1050m2/gm.
Filtration is achieved by the physical adsorption of molecules in the pores of the activated charcoal by Van
der Waals forces.
2. ACR FILTER
This filter is impregnated with halide salts and is used for the high efficiency removal of iodine and methyl
iodine. It is frequently used for iodination reactions with low-level radioactive iodine and efficiencies in
excess of 99.99% have been measured
3. FORM FILTER
This filter is impregnated with an oxidizing agent to oxidize formaldehyde to formate salts.
It is widely used in hospital pathology laboratories and suitable for use with formalin, gluteraldehyde and
aldehydes in general.

12. TRANSPORT, PACKING, STORAGE INSTRUCTIONS
ATTENTION: Disconnect the unit from the main power supply before doing any of the following
operations
Following indications are of the essence in case the end user has to transport, pack and storage the fume
cupboard after a first period of routine operation (e.g. laboratory/ plant moving):
- Disconnect the inlet tubes of gas/vacuum.
- If the fume cupboard exhausts to the outside of the building or is connected to the exhaust duct of the
conditioning system, remove the connection tube cabinet/outside - cabinet/conditioning system duct,
paying attention not to damage or to cover with dust (or any other material) the exhaust duct of the
fume cupboard.
- In case the fume cupboard is moved from a laboratory to another in the same building:
- By means of table with wheels: it is sufficient to put the cabinet on the table avoiding to turn it on a side
or on the back panel.
- By means of a forklift: put the cabinet on a pallet to ensure good conditions of stability and to prevent
the spill tray in the lower part of the fume cupboard from damages for transport.
- Pay attention not to damage the fume cupboard when passing through doors/windows
- If the cabinet is to be kept temporarily unused at the final destination, cover the cabinet itself with a
protective film (pluriball or expandable films).
- On the contrary, we recommend extreme caution on long-distance moving’s carried out by forwarding
agents (e.g. change of address): we suggest to use the same packages supplied by the manufacturer
with the cabinet made as follows :
