Installation by a1-envirosciences
The ST1 safety weighing enclosure must only be installed by a1-envirosciences
service personnel or personnel specifically authorised for this purpose.
Installation by a1-envirosciences is included in the delivery.
The a1-envirosciences technician checks the installation location, unpacks the ST1
safety weighing enclosure and sets it up. All supplied options will be installed properly. A
power socket must be available and accessible near the installation location. (If an
antistatic bar is used, a second mains connection must be available.)
This is followed by a functional check of the sensors, the alarm system and the HEPA
filtration system. The HEPA filter's retention rate is tested by means of a DOP test
(Dispersed Oil Particulate). After successful installation, the customer receives an IQ and
OQ.
Finally, the users are instructed in the operation of the enclosure.
Furthermore, a1-envirosciences recommends an optional detailed training by a
specialised a1-envirosciences employee.
Filter units - Notes on installation
The filter unit must be positioned from the ST1 safety weighing enclosure in a vibration-
decoupled manner. The installation location can be under or above the enclosure or on the
side. The filter unit must not be installed upside down.
The hose connections to the filter unit should not come in contact with the ST1 safety
weighing enclosure (vibration transmission and thus impairment of the scale functionality).
Installation by a1-envirosciences is included in the delivery. When the filter unit is installed
by a1-envirosciences, the inflow velocity is set and recorded in the IQ/OQ.
A considerable risk of contamination arises if the filtration system is installed
incorrectly or functioning improperly!
The filtration system may only be installed by a1-envirosciences or specially
authorised personnel. Installation by a1-envirosciences is included in the
delivery.
