Chemical agents

Problem How to resolve it

The ingredients in chemical agents

have a strong influence on the longevity

and functionality (throughput) of the

dispensing system. The dispensing

system (hoses and pumps) should be

set up for a particular type of chemical

agent.

General types:

–

Alkaline to pH neutral products,

–

acidic to pH neutral products,

–

hydrogen peroxide.

–

Use Miele approved chemical agents

in this machine.

–

Carry out a regular visual check of

the dispensing system for any

damage.

–

Regularly check the flow rate of the

dispensing system.

Chemical agents can damage

elastomers and plastics in the

washer-disinfector and accessories.

– Use Miele approved chemical agents

in this machine.

– Carry out a regular visual check of

any accessible elastomers and

plastics for damage.

The following oxidising chemical agents

can damage elastomers (hoses and

seals) and plastics in the

washer-disinfector:

–

Nitric acid,

–

peracetic acid,

–

products containing active chlorine.

The wash temperature should be

limited to:

– 50 °C Nitric acid,

– 35 °C with peracetic acid,

–

80 °C with products containing

active chlorine.

The following chemical agents can

release large amounts of oxygen:

–

Hydrogen peroxide,

–

peracetic acid.

–

Only use approved processes such

as OXIVARIO or OXIVARIO PLUS.

–

The wash temperature must be less

than 70 °C when using hydrogen

peroxide.
