Hot Foam Adjustment Procedure And Reference Scale - Nespresso Momento 120 Service Manual

4.7.2 Hot Foam Adjustment Procedure and Reference Scale

Milk foam adjustment has to be performed with the same type of milk that the customer is going to
use and must always be performed at the first installation of the machine.
Material
• Cappuccino cup (about 180 ml/60 Oz)
• Coffee Pods (Forte variety)
• Pre cooled cow milk (below 8°C), UHT or pasteurized 1.5% to 3.5% fat
Procedure
1. Set the air valve to 25% to start.
2. Dispense 4 test products by tapping on "test" and discard the frothed milk.
3. Dispense a ristretto (Forte variety) in the empty cappuccino cup.
4. Dispense milk foam at the centre of the cup until reaching the top of the cup (place the cup such that the
milk outlet will be centred above the cup).
5. Measure the width of the brown coffee ring as shown on the scale below (if the ring is not symmetrical,
take the average of both sides).
6. Compare the result with the scale below and proceed according to (a), (b) or (c).
NOT OK
(a) If the width of the brown coffee ring measures 17mm ± 3mm, the froth adjustment is complete.
(b) If the width of the brown coffee ring is too large then the foam is too liquid and the amount of air needs to
be increased. Restart from step 1 and increase the air valve value by 2%.
(c) If the milk foam surface has too many bubbles and/or no consistent ring then the amount of air needs to be
decreased. Restart from step 1 and decrease the air valve value by 2%.
