5.1 Cleaning the gas way
The heat exchanger houses a cotton wool filter that needs to be changed as soon as
it has become moist. For optimum protection, the outside of the device is fitted with a
water stop filter that seals off as soon as condensate or water or dust penetrates into
the gas way behind the cotton wool filter. The pump operation will become heavier if
the filter begins to seal off. For changing the water stop filter, the hose connectors on
both sides must be released. The filter can be exchanged without any problem and it
will be necessary to fit the hose connectors again securely.
The heat exchanger can be cleaned under running water.
The O-rings 14 x 1.78 (joints) of the heat exchanger (condensate spiral) must be
treated with a special lube at regular intervals so as to continue to work properly.
