ProCare Sure I-PM process indicators - Instructions on use

Application

ProCare Sure I-PM process indicators are used in the routine monitoring of washer-disinfectors.
They flag up changes to process parameters through comparison with a predefined reference value.

The operative mechanisms in the washer-disinfector are determined by the interaction of the following parameters:

• Detergent

• Time

• Temperature

• Mechanical action

• Water quality.

For instance, differences in cleaning intensity can result from the type of detergent used (e.g. alkaline, mildly alkaline/enzymatic) or the
water quality (e.g. softened or demineralised water).

In addition to technical parameters monitored by the washer-disinfector itself, such as dispensing and spray pressure, process indicators draw
attention to any discrepancies based on a comparison with reference values defined during performance qualification, e.g. changes in water quality.
Process indicators do not furnish proof of cleaning performance and are not intended as a substitute for parametric approvals by trained users.
Miele recommends the use of at least two process indicators in each cycle.

Use - General preparatory work

During commissioning or validation, two process indicators are included with the requisite load configuration throughout an entire programme cycle
and reprocessed together with the load to provide an initial cleaning reference with respect to the given load configuration. Miele recommends the
use of at least 2 process indicators per reprocessing cycle.
A documentation sheet is used to document both the reference and routine values. Documentation is facilitated by removing the adhesive backing
from both indicators and applying them to the documentation sheet. The initially cleaned indicators serve as a reference for all future reprocessing
cycles in which indicators are used. In order to capture values from the entire chamber, process indicators should be positioned diagonally opposite
each other, one at the front and one at the rear. On models with two rack levels, position a process indicator on each of the two levels. On models
with one rack level only, place one indicator at the front and one at the back in diagonally opposite corners (

). Both holders containing process

indicators can be attached to load carriers or to lower and upper baskets (

). When using inserts, process indicators may also be attached directly

to inserts if they would otherwise be shielded by the load. The colour bars should always face the centre of the chamber. Process indicators should
always be located in the same positions during both generation of the reference and routine testing.

Product description

A sheet of indicators consists of 32 individual indicators. The sheet
is perforated between pairs of indicators in order to facilitate the
use of double indicators through folding. Three colour bars, each
with different degrees of cleanability, are printed on each of the
self-adhesive and temperature-resistant process indicators. The
colour bars represent synthetic and non-toxic test challenges with
varying degrees of adhesion. This guarantees that a broad and
differentiated range of parameters are covered, e.g. water quality
and the mechanical action of the spray arms.
