4.7 REMOVAL AND INSTALLATION, AIR DRYER FILTER ELEMENT
Note:
To be certain that the air dryer is functioning
properly, the air reservoirs should regularly be
checked for condensation. If more than the
normal amount of water is drained off repeatedly,
the air dryer element must be replaced. Under
normal circumstances the element must be
replaced at least once per year.
Removing air dryer filter element
1. Vent the air dryer by allowing it to regenerate
or by loosening the compressor line (1), so
that the interior of the air dryer is
depressurised.
2. Remove the filter element by turning it anti-
clockwise using a filter strap spanner.
3. Dispose of the drying element as if it were an
oil filter.
4. Clean the air dryer internally.
5. Check the air dryer threaded connection (2)
for damage and then lubricate it sparingly
with grease.
Installing the air dryer filter element
1. Lubricate the sealing ring of the new filter
element sparingly with grease.
2. Fit the filter element by manually tightening it
until the sealing ring abuts. Then tighten the
element by hand (approx. 1 turn).
3. Fasten the compressor line (1).
4. Pressurise the system and then check the air
dryer for any air leaks.
