Maintenance
External care: Remove any dirt on the housing with a moist cloth. Do not immerse the appliance in water!
Avoid a decrease in efficiency:
Air stones and other air-operated articles become clogged by limescale, etc. in the course of time. Therefore, the air stones
need to be checked from time to time and replaced if necessary. Check other air-operated articles for optimum passage and
clean them if necessary.
Diaphragm replacement:
Lower efficiency even when the air stones are not clogged can be an indication of a defective diaphragm. The diaphragm
may need to be replaced every 6 - 12 months. All diaphragms and other parts subject to wear and tear can be purchased as
a spare parts kit. Please make sure to always replace the entire kit in order to ensure optimum efficiency. This maintenance
work must only be carried out by a qualified person.
Other notes:
How to minimise noise: The JBL PROSILENT
a noise suppression chamber and a particularly thick housing. Nevertheless, the operating noise may be audible even when
optimally installed, especially at night in a quiet room.
Every air pump generates vibration and buzzing noises, which may be audible to a certain degree. These can be minimised
noticeably by counter-pressure. A reduction of the flow rate at one of the flow rate controls reduces the noise level signifi-
cantly.
Therefore, when using the models with two air connections, never operate an air connection in "idle" i.e. without an
attached hose with an air stone or similar! This results in premature wear of the diaphragm and an increased noise level.
