Maintenance
To instigate additional cleaning cycles, switch the machine off, and then on again.
Depending on the amount and nature of use, the vaporiser tubes may need physically cleaning or replacement. Since the
tubes are ‘straight’ in form, a push rod cleaning type tool can be used to clear any excess formations.
Occasional emission of small glowing carbon particles during the cleaning process indicate that this excess formation should
be cleared.
Replacing these tubes is merely a matter of removing the top cover on the moving arm, releasing the tube retaining bolts,
fluid tube and sensor plug, and fitting a new unit in place. ( see diagrams)
With the arm in its lowest position, remove the 8 M3.5 cover bolts and cover
Snip the nylon ties holding the silicon feed tubes onto the pipe and push the tubing off.
Release the M4 lock nut on the front brass terminal block, and undo the M4 cap head bolt using a driver size 3 hex key.
Release, but do not fully undo, the M4 bolt securing the terminal clamp to the input end of the tube. ( Phillips screwdriver and
small M4 spanner)
Unplug the appropriate thermocouple lead. (centre tube to lower connector, outer tube to upper connector)
Release the front end of the tube from the brass connector block and pull the tube forward to remove.
Replace the tube in the reverse order and check for correct operation without leakage etc. The tube may need a few hours to
settle in.
Make sure all air vents are free from restrictions
Keep the machine clean and free of debris or fluid that could enter the machine and cause problems.
Do not apply excessive force to the moveable haze ‘arm’ or let it drop without support
