Note: Every week or so this should be open for a few hours when the compressor is
running!
4.2. Air tubes:
Connect the PVC tubes in blue 'Quick fit' fittings. Keep the valve lever closed at the tone
arm.
There are two pieces of PVC air supply tubing. The shorter connects the air supply from the
red filters to the tonearm and the longer connects the compressor to the red filters. On one end
of the longer tube is a valve. This end should be connected to the input of red filters. The
valve lever should be in “close position” (as supplied i.e. with lever at 90 degrees to the
tube). The other end is plugged in at compressor output. See page 6.
4.3. Silver filters (dryers):
Note: Keep the silver filters in an upright position. They might leak otherwise.
Note: They should be sealed; otherwise the compressor can not build up pressure.
The silver filters which are positioned near the tonearm have an automatic drainage system.
When full air pressure is reached in the compressor (and compressor stops), open valve on the
tube before the silver filters (allowing the air to flow in). This will automatically seal the
automatic drain systems in these dryers. If there is no pressure inside, they will not seal.
There is no need to do this manually (unless if there is no valve on supply tube). Check if it is
sealed properly by listening for any hissing noises.
