3.
Like any other air pump,
this by placing on a rough surface that is absolutely horizontal if possible. As a precaution, secure the air pump with a
wire or cord that you thread through the hole on the bottom of the housing and attach to the wall with a hook.
4.
Cut an air hose of a suitable length and connect one end with the air connection of the air pump. Attach the other
end of the air hose to the air connection of an air stone or another air-operated article. Place the air stone or the air-
operated article in the aquarium. Avoid an excessively long air hose, since this can decrease the efficiency of the air
pump.
5.
Connect the air pump to the power supply.
Maintenance (Fig. C)
External care: Remove any dirt on the housing with a damp cloth. Do not immerse the device in water!
Avoid a decrease in efficiency:
Check the air filter located on the bottom of the device regularly for dirt and replace as necessary.
Air stones and other air-operated accessories can become clogged by calcium build-up, etc. in the course of time. Therefore,
the air stones should be checked from time to time and replaced as necessary. Check other air-operated articles for optimum
airflow and clean them if necessary.
Diaphragm replacement: Decreasing efficiency with no clogging of the air stones is an indication of a defective diaphragm.
The diaphragm may need to be replaced every 6 - 12 months. The diaphragm and other parts subject to wear and tear can
be purchased as a premounted spare parts kit with an anchor and noise suppression chamber. Please make sure to always
replace the entire kit in order to ensure optimum efficiency:
1.
Remove the screws on the bottom of the device and lift the lid of the device.
2.
Pull the complete unit consisting of the diaphragm, anchor and noise suppression chamber upwards and out.
Reverse the operation to insert the new unit.
3.
Replace the housing lid and screw it tight.
Other notes:
How to minimise noise: The JBL ProSilent air pumps were developed according to the latest findings and equipped with a
noise suppression chamber and a particularly thick housing. Nevertheless, the operating noise may even be audible under
