7. MAINTENANCE ACTIVITIES
In order to ensure safety in the course of cleaning, it is necessary to disconnect
the device from the mains. With this condition met, uninstall the weighing pan
and other detachable components.
Cleaning the weighing pan while still installed may cause
damage of the measuring system.
7.1. Cleaning ABS Components
To clean dry surfaces and avoid smudging, use clean non-colouring cloths
made of cellulose or cotton. You can use a solution of water and detergent
(soap, dishwashing detergent, glass cleaner). Gently rub the cleaned surface
and let it dry. Repeat cleaning process if needed.
In the case of hard to remove contamination, e.g. residues of adhesive, rubber,
resin, polyurethane foam etc., you can use a special cleaning agents based on
a mixture of aliphatic hydrocarbons that do not dissolve plastics. Before using
the cleanser for all surfaces we recommend carrying out tests. Do not use
cleansers containing abrasive substances.
7.2. Cleaning Glass Components
Select dissolvent depending on a dirt. Never soak the glass panes in alkaline
solutions since they interact with glass and may cause damage. Do not use
cleansers containing abrasive substances.
For organic dirt use acetone first, next use water or detergent. For other than
organic dirt use diluted acid solutions (soluble salts of hydrochloric or nitric
acid) or base solutions (ammonium or sodium base). To remove ACIDS use
protophilic solvent (sodium carbonate), to remove BASE use protogenic solvent
(mineral acid of various concentration).
In case of heavy contamination use brush and detergent, nevertheless avoid
detergents containing large and hard molecules which could potentially scratch
glass panes.
