*Valve on drain tube: Optional by order.
For normal operation this should be open (level along axis of tube). If used in the same
room as tone arm it should be closed. This prevents noise when switching off
compressor. Every week or so this should be open for a few hours when the
compressor is running!
Dryers:
Dryer with stands
The pressure should now build up to about 8 bars (120 psi) when the system will
switch off automatically. It will be switched on automatically when the pressure drops
to around 6 bars (90 psi). Note: Keep the red filters in upright position.
The red filters which are positioned near the tonearm have an automatic drainage
system. There will be some leakage when the air pressure builds up in the system for
the first time after you open valve on incoming tube. If they are still leaking do this:
when the pressure in the reservoir shows at least 1-2 bars (20-30 psi), lift the red filters out of
the stands( keeping them in vertical position) and you will hear a slight noise due to the
leakage of air. At the bottom of the filters are two black plastic outlets for drainage. Just close
them with fingers for about 20 – 30 seconds and then quickly remove fingers. This will seal
the drainage system and there should be no further leaking noises. Put them back into
stands .
On the tonearm remove the security wire which has restricted movement of the arm
bearing during transport. The tonearm is not balanced, as there is no extra weight on
the headshell. When the air bearing is functioning, the counterweight will rotate the
tube so that the headshell will go up. To avoid this, mount the cartridge in the
headshell with stylus guard on. Open the valve. Pressure on the small pressure guage
on the tonearm, should show about 4 bars.
By holding the headshell and lifting it, so that the counterweight support is not
touching the cueing device rod, gently move the tonearm towards the centre of the
platter a few times and also rotate it up and down. If you feel any resistance do not
push but check the air supply or pressure. Check wire and air supply loops to ensure
that they are not crossing each other.
