5.4.3 Cartridge Replacement Procedure (PCO2-800 to PCO2-4800 Models)
The top manifold has been split into two sections in order to simplify the removal of the desiccant cartridges.
A
Remove the M12 nuts from one side of the manifold.
B
Using the handles, carefully lift the manifold until the M8 hex bolt has travelled to the top of the manifold hinge. Gently pull the manifold
towards yourself until it has locked into position.
C
Carefully rotate the manifold 180
o
as shown. Once opened, place an M10 locking bolt through the holes in the two halves of the hinges to
prevent the manifold falling onto the operator during service.
D
Remove the old desiccant cartridges and dispose in accordance with local regulations.
Note: The cartridges should only be lifted using the handles and directly upwards to prevent clashing with the hinged manifold.
E
Remove the o-ring from the outlet manifold block and replace with the one provided within the 12 month Preventative Maintenance kits.
Note: Apply a light coating of Molykote III grease to the o-rings.
F
Insert the replacement desiccant cartridges into the columns.
Refit the manifold and secure the M12 nuts in sequence, starting with the centre nuts and working outwards. The nuts should be secured in
two stages.
Stage 1: 27Nm (20 ft.lb) and Stage 2: 40Nm (30 ft.lb)
.
Replace the desiccant cartridges on the opposite side following the same procedure as above.
Ensure that the system is fully depressurised before carrying out the below maintenance procedures.
Take care not to trap fingers/hands on the handles when rotating the manifold.
