Follow all the precautions outlined in the previous
section for the 10 micron filter.
Replacing the 1 micron filter:
1. Make sure the water blasting system is shut-
down and the truck is in the service posi-
tion.
2. Close the clean water supply valve and bleed
pressure from the charge water system.
3. Remove filter canister lid and retainer ring.
4. Remove the filter retainer bolt and filter. Then
flush filter canister to remove debris and con -
taminants with clean, fresh water.
5. Apply a thin coat of anti-sieze to the filter
retainer bolt threads.
6. Insert the new filter and retainer bolt into the
filter canister. Hand tighten the retainer bolt
just enough to seat the filter (snug). Make
sure not to over tighten the bolt and col-
lapse the filter cartridge.
7. Coat the retainer ring threads with anti-sieze
and install filter canister lid.
8. Open the clean water valve, reactivate the wa-
ter blasting system and follow the instructions
to purge air from the charge water system in
the next section of this chapter.
9. Activate the charge pump and flush the low
pressure side of the pump and charge water
system using the flush valve before operating
the UHP pump after changing the filters.
