Maintenance (Fig. C)

External care: Remove any dirt on the housing with a moist cloth. Do not immerse the appliance in water!

Avoid a decrease in eciency:

Check the air lter (ProSilenta100 - ProSilenta400) located on the bottom of the device regularly for dirt, and replace if neces-

sary.

Air stones and other air-operated articles become clogged by limescale, etc. in the course of time. Therefore, the air stones

should 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: Decreasing eciency 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. 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 eciency:

1. Remove the screws on the bottom of the appliance and lift the lid of the appliance.

2. Models ProSilent a100, ProSilent a200 (Fig. C2 a-h): Pull the complete unit consisting of the diaphragm, anchor

and noise suppression chamber upwards and out. Reverse the procedure to insert the new unit. Please make sure

the plug washer on the bottom of the component ts properly. The plug washer usually adheres to the small pipe

nozzle / connecting piece on the pump housing that becomes available. Apply some Petroleum jelly (Vaseline) to

the plug washer before installing the new component. This ensures proper t when the component is installed.

Models ProSilent a300, ProSilent a400: Proceed as shown in Fig. C 2 a-h. Pull both diaphragms o of the valve

plate, swivel the anchor arms outwards and pull the anchor arms out of their mounting on the noise suppression

chamber. Loosen the screw in the middle of the valve plate and remove both valve plates. Mount the new valve

plates and anchor arms with the diaphragms in reverse order. When mounting the valve plates, make sure that

the cylinders catch in the corresponding drilled holes of the rubber seals and the noise suppression chamber on

their rear side. Make sure to always use all of the parts contained in the spare parts kit.

3. Replace the housing lid and screw it tight.
