Maintenance
Overview
Iris Sample Processing recommends that instrument operators perform periodic inspections and
preventative maintenance on all instruments. Contact customer service department or your
distributor if the instrument is not functioning properly.
CAUTION - Unplug the Express 3 from the wall outlet before cleaning or performing
maintenance.
WARNING – Do not expose the Express 3 or its rotor to strong or concentrated acids,
bases or oxidizing agents, aromatic or halogenated hydrocarbons, esters or ketones.
Cleaning
The Express 3 is supplied with a disposable bowl liner to simplify routine cleaning. Additional bowl
liners are available (Product No. DL02). The liner should be replaced as needed. Clean the outside
surfaces and switch overlay panel with a water-dampened cloth and mild detergent. Clean the inner
surface or bowl with a mild detergent, and if necessary, a disinfectant, wiping surfaces with a
dampened cloth using 70% alcohol or 10% bleach solution.
CAUTION - Do not spray cleaning solutions directly onto the centrifuge bowl or
housing; overspray could reach the motor bearings or internal circuitry. Subsequent
damage may not be covered by warranty.
