6. If a dewpoint sensor is fitted, disconnect the nut attached at outlet block [Fig B.4] and
pull through the tubing, (maintain attachment to the sensor assembly).
7. Remove the black plastic conduit, if present, from the top of the dryer’s top manifold.
8. Remove the front door. Pins located inside on the left (The door will be unsupported
once the top manifold is removed).
9. Undo the M12 retaining bolts from the top manifold. (8 bolts per column)
10. Remove the top manifold (care should be taken not to damage the sealing face).
11. Remove all of the column caps exposing the drying media.
12. Using a suitable vacuum cleaner, remove the expended dessicant media from each
column.
13. Remove any contaminants from the columns internal surface.
14. Using a nano suitable snow storm filler, replace the dessicant media ensuring
continuous filling is maintained. A gap of 30mm must be left free at the top of each
column for the column cap [figure B.5].
15. Install a new 150mm diameter media disc onto the
top of the dessicant fill and fit column caps.
16. New column top caps must be installed. (Caps
should stand approx.2mm above column length).
17. Clean top manifold and replace all gaskets (use a
suitable grease to hold gaskets into place).
18. Ensure all column sealing faces are clean and free
from dust.
19. Reassemble the dryer by replacing the top manifold
ensuring it is lined up correctly with the columns,
using Guide Pins (see parts list). Insert all M12 bolts
and torque to a setting of 80Nm following the
correct tightening sequence on page 19-20.
20. Refit the door.
21. Refit the black plastic conduit to the top of the
manifold and re-connect the 4 x plastic 6mm
tube to the exhaust valves and control solenoid
valves. (If E.S. is fitted re-connect the 4mm clear
tube).
22. Re-connect the outlet manifold connection using 4 x
M10 bolts.
23. Replace the top cover.
24. Start up the Dryer (see page 8)
