Adding and dispensing process chemicals

Neutralizing agent
For certain programs, neutralizing agent is dispensed in the interim
rinse phase after washing to help prevent discoloration and corrosion
spots on the instruments (especially around jointed areas).
Neutralizing agent (pH setting: acidic) neutralizes any residues of al-
kaline process chemicals on the surface of the load.
In case of a film build-up on the load, a neutralizing agent based on
citric acid must be used.
Neutralizing agent is dispensed automatically in the Interim rinse
phase after the main wash (see “Program charts”). The reservoir must
be filled and the dispensing system vented for this to occur.
Replenishing neu-
tralizing agent
Place the neutralizing agent container (red marking) on the open
cabinet door or on a surface which is robust and easy to clean.
Take the lid off the canister and remove the suction wand. Place the
suction wand on the open wash cabinet door.
Replace the empty container with a full one.
Push the suction wand into the opening of the container and secure
the lid. Observe the color coding.
Feed the suction wand into the container until it reaches the bot-
tom.
Wipe up any spilled process chemical thoroughly.
Place the container on the floor next to the machine or in an adja-
cent cabinet. The container must not be placed on top of or above
the machine. Make sure that the dispensing hose is not kinked or
trapped.
After that, the dispensing system must be primed (see “Settings /
Priming DOS”).
