For chromium steel alkaline detergents in the pH range 8 -- 14 are preferred. Acid based
detergents should only be used for stainless steel items. Medical devices made of aluminium
need specific washing agents designed especially for them. Please note that different chemicals
may require different process temperatures and times e.g. enzymatic cleaners a temperature
between 30 - max 45 degrees Celsius, whereas an alkaline one a temperature between 60 to 90
degrees. The instructions from the manufacturer of the chemical e.g. regarding the concentration
and temperature shall be followed. Volume of water in the washing phase is 11 litres.
Please follow the instructions of the manufacturer of the chemical additive for safe handling, data
on the biocompatibility (e.g. the maximum permitted residual level on devices). Note that the
residual level, which can be tolerated, will depend upon the nature of the chemical and the
intended use of the product being cleaned. The specified performance may not be achieved if
other process chemicals than those, which have been tested during type testing, or separately
with certain process variables, are used.
NOTE ! When using special chemicals, pls find out from the chemical supplier the suitability
for chamber material AISI 304 (EN 1.4301, BS 304 S31) and chemical dosing system materials
PVC and Silicone.
Chemical hoses are marked with the symbols: Detergent

Requirements on detergent in Deko washer-disinfectors
1.
Use only liquid detergents.
2.
The detergent must not foam. Even a small amount of foam will substantially
decrease the cleaning effect.
In case there is plenty of foam in the system the machine is unable to clean
the goods and the automatic foam removal control will start. The machine will
take clean water in and flush the foam into the outlet.
3.
The liquid must be free of particles so that the nozzle or the valves of the
detergent pump will not get blocked.
4.
Normally detergents being used are highly alkaline with a pH-value
between 10 and 14.
A strongly alkaline liquid will corrode aluminium and its colouring.
Please use special washing agents for aluminium items.
The detergents are powerful and must be handled with care.
In case of accidental contact with the skin or clothing wash immediately
with clean water. For eyes, seek immediate medical attention.
Tighten the stopper properly in order to prevent accidental
spilling. If air tight it could implode container.
