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
XXXXmm.

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

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.
