General Maintenance
• Check the charge water pressure frequently.
If the Charge Pump pressure is lower than 30
PSI, replace both of the filters between the
charge pump and the high pressure pump.
If the pressure is still low, the charge pump
impeller may need to be replaced or there is
a water supply problem. Do not operate the
UHP pump when the charge pressure is below
30 PSI.
Periodic:
• Inspect the pump for signs of seal leakage
and bearing wear at each engine oil change.
• Replace the impeller at regular intervals as
recommended by the pump manufacturer.
Bilge Pump
The bilge pump returns packing cooling and lube
water from the ultra high pressure pump to the
waste tank. It is a centrifugal pump that requires
little maintenance. It can run dry for short peri-
ods without damage, but prolonged dry operation
will cause the seals to overheat and damage the
pump.
Information and owner’s manuals for the bilge
drain system components are included with this
manual. Refer to this information for additional
operation and service data.
Inspection and Routine Maintenance:
Daily:
• Inspect the cooling water sump in the UHP
pump daily and clean any debris that may
restrict drainage to the bilge pump system.
• Inspect the drain hoses and sump system for
loose fittings and leaks daily.
• The bilge pump is activated by an automatic
float switch in the drain sump. Monitor the
operation of the bilge pump system at the
start of each shift to make sure the pump and
automatic switch are operating properly.
Periodic:
• Remove the lid for the bilge drain sump box
and clean debris that may reduce drainage to
the bilge pump or interfere with the operation
of the float switch weekly.

Vacuum Blower and Filter Canister
6.7 Vacuum System and Waste Tank
Blower and Filter Canister
The vacuum blower has specific lubrication and
maintenance requirements. Refer to the vacuum
blower manufacturer’s operating manual for lubri-
cation specifications and maintenance schedules.
Be sure vacuum filter is always in good operat -
ing condition so it fully protects the blower from
collecting vacuumed debris internally. If debris
ever gets into the blower impellers, use a paint
or lacquer thinner or other non-corrosive cleaner
to remove any residue build-up inside. It will be
necessary to remove the silencer in order to clean
the blower. Remember that if large debris gets
into the blower, it can cause severe damage to
the blower.
