Osmetech OPTI™ 1 Systems
The Osmetech OPTI 1 is completely housed in a molded plastic case which
provides a chassis for the electronic and mechanical assemblies. The analyzer is
designed for quick removal of all major assemblies. Some of the components
such as the printer, pump cartridge and top plate are accessible from the outside
of the analyzer. The analyzer interior is accessible, after removing the bottom of
the analyzer. The following chapter describes the removal of the major
assemblies of the Osmetech OPTI 1.
Caution: Before disconnecting any analyzer assemblies disconnect the analyzer
from primary power and remove the installed battery to avoid electrical damage
Pump Cartridge
Removal
The pump cartridge can be removed easily. Open the printer compartment cover
to access the pump cartridge. Grasp the pump cartridge and pull straight up to
free it from the pump motor shaft. The label on the pump cartridge contains the
date of manufacture (DOM: WW – 2 digit calendar week; YY – 2 digit year).
The pump cartridge should be replaced if it is more than 12 months old.
Installation
To install the pump cartridge, first check whether the flat in the pump spool is
aligned with the flat on the pump motor shaft. If is not aligned, a coin can be
used to turn the spool within the pump cartridge housing to align the pump spool
with the motor shaft. The motor shaft may also be turned for easier reinstallation
of the pump cartridge. For easiest alignment of the motor shaft, turn the motor
shaft so the flat on the motor shaft is parallel to the right side of the analyzer
housing with motor shaft flat to the right.
