2.3.4 Put the filter element in a suitable cleansing liquid. The cleansing liquid must only reach up
to the bottom edge of the element plate (Fig. 3/2) so that no contaminated liquid can
enter into the filter candles (14) from the top. The top area of the gauze must be visible in
the filter candles. Soaking time as required by the suppliers of the cleanser, but maximum
4 hours.
2.3.5 Take the filter element out of cleansing liquid and blow through filter candles (14)
with compressed air (Fig. 2/W1) (sequence of operations 2.2.4).
Air pressure max. 10 bar.
2.3.6 Put the filter element again in clean cleansing liquid, allow to drip dry and blow through
with compressed air (W1). Turn filter element upside down, so that the cleansing liquid can
drain off.
2.3.7 Check the filter candles occasionally for damage (sequence of operations 2.4).
2.3.8 Put the filter element in the chamber, fit the cover and renew the gasket if necessary.
2.3.9 Fill the filter chamber and vent it (see the plate on the filter cover).
2.4 Cleaning the filter candles in the case of heavy soiling.
Note:
In the case of heavy soiling of the filter element (paint spots, incrustation, tar deposits,
fibers, chips), remove filter candles and clean them individually.
2.4.1 Soak the filter element in cleansing liquid (max. 4 hours).
2.4.2 Disconnect the base plate and carefully remove the protective shell from the filter element.
2.4.3 Remove the filter candles (14) with the drift (Fig. 3/W2) downwards and tilt them out. Re-
move the O-ring (25) between the filter candles and the element plate (2), because O-rings
must not have contact with the cleansing liquid.
2.4.4 Inspect the filter candles and renew them in the case of damage and/or heavy folding of
the gauze.
Attention:
The damage on only one filter candles means malfunction of the whole element.
Do not put the removed filter candles one upon another; this might damage the gauze.
2.4.5 Connect the cleaning pistol (Fig. 2/W1) to the compressed air supply.
Air pressure max. 10 bar.
