Replacement of top gasket seals, cartridges,
O-rings and valve ball:
Remove the 8(qty) M6x25 cap screws (12) and washers (14) as well
GB
as the 2(qty) M6x50 cap screws (11) and washers in order to remove
the top common manifold (24).
Once these screws are removed, the top common manifold and the
outlet purge block (22) can be taken off the aluminum extrusion (21).
This will expose the dryer cartridges (25) which can be taken out of
the extrusion and replaced with the new cartridges.
The outlet purge block (22) can be taken off the top common
manifold (24) by removing the 4(qty) M4x18 screws (10). Once this
is removed, the valve ball (2) can be replaced as well as the 2(qty)
35mm o-rings (4) and 1(qty) 19mm o-ring (5). The gasket seal (3)
under the common manifold must also be replaced at this point.
Once all components are replaced, reassemble the common
manifold and the outlet purge block back.
NOTE: Torque all M6 bolts to 5 N.m and all M4 bolts to 3 N.m.
WARNING! Make sure that the dryer cartridges are installed
with the handle up for proper functionality.
IMPORTANT! After servicing the dryer, make sure to reset the
dryer service interval counter by depressing the first 2 selection
buttons on the PLC for a minimum of 15 seconds.
Replacement of bottom gasket seals, O-rings
and valve ball:
Note: Unscrew solenoid cables (not shown) from the solenoid valves
(18) before servicing the bottom of the dryer. The fittings on the
valve block (23) need to be removed first in order to remove the M6
cap head screws (12).
Remove the 8(qty) M6x25 cap screws (12) and washers (14) as well
as the 2(qty) M6x55 cap screws (13) and washers in order to remove
the bottom common manifold (24) from the bottom of the extrusion.
Remove the 4(qty) M4x35 cap head screws (9) and anti-vibration
washers (15) in order to take the valve block (23) off the common
manifold (24).
Once the valve block is removed, you can replace the bottom valve
ball (2) as well as the 2(qty) 35mm o-rings (4) and 1(qty) 19mm
o-ring (5). The gasket seal (3) under the common manifold must also
be replaced at this point.
Once all components are replaced, reassemble the common
manifold and the valve block.
NOTE: Torque all M6 bolts to 5 N.m and all M4 bolts to 3 N.m.
Replacement of dryer solenoid valves:
If replacement of the dryer solenoids is needed at the time of seals,
o-ring and valve ball replacement, follow the same steps in the
replacement of the bottom gasket seals, o-rings and valve ball with
the following additional steps:
Once the bottom common manifold and the valve block are
disassembled, make sure to remove screws M4x12 cap head screws
(8) in addition to removing the M4x35 screws (9) in the valve block.
This will allow the solenoid valves (18) to be removed and replaced
with the new solenoid valves. Once the solenoid valves are changed,
reassemble the solenoids with the M4x12 and M4x35 screws onto
the valve block and the valve block onto the common manifold (24).
Finally attach the bottom assembly to the extrusion with the M6x25
cap head screws (12) and the M6x55 (13) screws.
NOTE: Torque all M6 bolts to 5 N.m and all M4 bolts to 3 N.m.
WARNING! Make sure the dryer solenoids being replaced
have a voltage rating which matches the product label.
