NOTE
If the nebulizer cleaning procedure does not solve the problem, contact your local distributor for
a nebulizer replacement.
In case the black gas tubing has been removed, make sure you are using the correct orientation,
where the white one-way valve is at the lower end (near the gas arrival). Avoid leaks at all con-
nections and check for possible leakage when you turn the pump on again.
