Enviro ST1 - Location Selection

Division:
15 I 77
Location selection
The installation location of the ST1 safety weighing enclosure has a direct
effect on the functionality of the safety weighing enclosure as well as on the
application installed in it. Please note the information below when selecting a
location.
 Little through traffic and draughts through ventilation systems, windows or corridors
as otherwise transverse flows could develop in front of the work opening, obstructing
the low-turbulence airflow into the enclosure.  Danger due to substance leakage!
 Even, stable and vibration-decoupled, vibration-free substructure to maintain the
functionality of the analytical balances used (if one is used).
 Good visibility and lighting must be ensured at the installation site.
 Clean and, if necessary, decontaminated set-up area. The installation location must
not be chemically, physically or biologically contaminated.
 The front of the ST1 weighing enclosure must be as close as possible to the weighing
table so that the arm bar protrudes slightly to allow good airflow to the flow sensors
(not required for IE series).
 A comfortable chair suitable for laboratory use with an upright backrest and height
adjustment should be provided as an integral part of the work area.
a1-envirosciences recommends adjusting the seat height according to body size so
that the forearms are approximately at a right angle to the upper arms in the working
position.
 The scope of delivery of the ST1 safety weighing enclosure includes a ventilation kit
that connects the weighing enclosure to the filter unit. The ventilation hoses
contained in it must not be kinked and come in contact with the ST1 safety weighing
enclosure and must be freely accessible.
 If the ST1 safety weighing enclosure is to be connected directly to the building's
exhaust air system (not recommended), an adjustable valve must be installed in the
system to regulate the air flow and to ensure the required inflow velocity (0.35-0.45
m/s).
 Special care must be taken with ST1 safety weighing enclosures that are connected
to a building's exhaust air system if gases, aerosols and/or particles are released and
exhausted into it. Here, special attention must be paid to the chemical compatibility
of the substances in the various exhaust air system ducts.
