Step-by-step plan HappyLiner Vented
With the HappyLiner with head ventilation, it is important that the hole underneath is closed. Here is the step-by-step plan:
- Close the hole in the stainless steel part under the cup, the stainless steel milk collection part;
- Make the hole clean and dry;
- Press the silicone plug a bit into the hole, +/- 5mm;
- Cut off the remaining protruding part of the plug with a sharp knife;
- Press the silicone plug into the hole with a blunt object (for example, an Allen key) until it goes no further, so that the plug is recessed in the hole of the stainless steel milk collection part.
- It is also good to check the pulsation settings in T4C.
The standard settings are:
- 60 strokes per minute
- 43 kpa
- 65 / 35 suction/rest ratio
