Adding and dispensing chemical agents

Neutralising agent
For certain programmes, neutralising agent is dispensed in the interim
rinse phase after washing, to help prevent discolouration and corro-
sion spots on the instruments (especially around jointed areas).
Neutralising agent (pH setting: acidic) neutralises any residues of al-
kaline cleaning agents on the surface of the load.
Where there is build-up of deposits on the load, a citric acid based
neutralising agent must be used.
Neutralising agent is dispensed automatically in the
Interim rinse
phase after the main wash (see Programme charts). The reservoir
must be filled and the dispensing system vented for this to occur.
Refilling
neutralising agent
Place the neutralising agent container (red marking) on the open
cabinet door or on a surface which is robust and easy to clean.
Unscrew and remove the siphon. Place the siphon on the open
cabinet door.
Replace the empty container with a full one.
Push the siphon into the opening of the container and screw it back
on tightly. Observe the colour coding.
Wipe up any spilled chemical agent thoroughly.
Place the container on the floor next to the machine or in an adja-
cent cupboard. The container must not be placed on top of or
above the machine. Make sure that the dispensing hose is not
kinked or trapped.
The dispensing system must then be vented (see “Settings
/DOS
venting”).
