4.5.1 Detergent
Detergents are alkaline (pH value should be > 7) and are needed to dissolve soiling
from the washware. The standard setting is 2 ml of detergent per litre of tank water.
If necessary, the concentration can be adjusted depending on the water quality,
washware and degree of soiling. This setting is made during commissioning by an
service technician authorised by MEIKO or the chemical supplier.
Change dosing quantity,
see chapter “Dosing system level” on page 42.
4.5.2 Rinse aid
Rinse aids are acidic (pH value should be between 2 and 7) and accelerate the dry-
ing of the washware by reducing the surface tension of the water so that it can run
off the washware quickly.
The correct dosage is achieved when the water drips evenly from the washware and
depends on the available water quality on-site. This setting is made during commis-
sioning by an service technician authorised by MEIKO or the chemical supplier.
Change dosing quantity,
see chapter “Dosing system level” on page 42.
4.5.3 Dosing equipment
The components of the dosing units are subject to high demands and must therefore
be regularly maintained and, if necessary, replaced in accordance with the mainte-
nance specification.
4.5.4 Suction lances
Suction lances with level monitoring for rinse aid (blue) and detergent (grey)
Suction lances ensure that the liquid chemical product is sucked in correctly. Suction
lances are inserted vertically into the canisters and are optionally equipped with level
monitoring. When the canister is running low, a message will appear on the machine
display.
4.5.5 Change of products
Caution
When changing the detergent product (even to a product from the same
manufacturer), crystallisation may occur, which can lead to failure of the
dosing system.
• When changing the detergent product, flush the dosing system with warm wa-
ter.
Procedure for changing the detergent product:
1. Provide a suitable container with warm water and insert the suction lance.
2. Thoroughly flush the dosing system several times by venting the lines, see
page 41.
3. Wipe the suction lance and put it into the canister with the other detergent prod-
uct.
4. Refill the dosing system by venting the lines .
