How to set up
Steps 1 and 2
Twist off Foamer Trigger Head by turning anti-clockwise. If it is stiff, press down firmly on top as you twist.
Fill to the line from your refill pouch. The fill line sits about 1 cm below the shoulder, exactly 300 mL capacity.
Step 3: prime and foam
Prime the pump by pulling the trigger vigorously 2 to 3 times. Then half-pull for a quick burst, full pull for a longer spray, or hold and pump for continuous foam (it will keep foaming for about 1 to 2 seconds after your last pull).
If the head is stuck
Freeze method
Pop Foamer Trigger Head in the freezer for 5 to 10 minutes. The cold contracts the plastic and can help loosen the seal.
Warm water method
Run the head under warm (not hot) water for 60 to 90 seconds. The slight expansion can free up stubborn air-seals that can form.
If it clogs
Twist off Foamer Trigger Head and soak it in warm water for a minute, then pump the trigger 12 or more times to flush it through.
