6 Cleaning and maintenance
The machine becomes dirty through use. The waste materials can have an effect on the
appropriate functioning of the machine and, moreover, constitute a risk to hygiene. In order
to exclude any dangers due to lack of hygiene and to make it possible for the machine to
function properly, it is important to carry out maintenance work regularly and carefully. This
chapter deals with preventive measures and procedures relative to maintenance.
6.1 Guidelines and methods
In order to clean the machine in a safe and responsible manner the following guidelines must
be closely followed.
Failure to observe these guidelines can result in
serious bodily injury and damage to the machine.
6.1.1 Cleansers
Cleansers are used to clean the machine. Not all cleansers are suitable for the machine. So
follow the guidelines below during cleaning activities:
- Read the supplier’s instructions before use.
- Use cleansers with a pH value between 6 and 9.5. Acid cleansers can discolor the
surface of components.
- Use a low-pressure foam-cleaning unit (max. 6 bar water pressure) with warm
running water (40 to 50C/104 to122F).
- It is not permitted to use a high pressure or steam cleaner.
- To get rid of calcium deposits only cleansers based on citric acid may be used.
- Use disinfectants only based on alcohol.
- The use of cleansers or disinfectants based on chlorine is not permitted.
If you have questions about cleansers, please consult your Repak agent.
When using cleansers, avoid skin contact and
wear protective garments as described on the
packaging.
