Perkins 1206E-E70TTA Operation And Maintenance Manual page 81

SEBU8601-04
• Perkins recommends the use of bulk fuel filter /
coalescer units which clean the fuel of both
particulate contamination and water in a single
pass.
• Ensure that you use Perkins Advanced Efficiency
Fuel Filters. Change your fuel filters per
recommended service requirements or as needed.
• Drain your water separators daily.
• Drain your fuel tanks of sediment and water per
the Operation and Maintenance Manual
instructions.
• Install and maintain a properly designed bulk filter
/ coalescer filtration system. Continuous bulk
filtration systems may be required to ensure that
dispensed fuel meets the cleanliness target.
Consult your Perkins distributor for availability of
bulk filtration products.
• Centrifugal filters may need to be used as a pre-
filter with fuel that is severely contaminated with
gross amounts of water and/or large particulate
contaminants. Centrifugal filters can effectively
remove large contaminants. Centrifugal filters may
not be able to remove the small abrasive particles
required to achieve the recommended "ISO"
cleanliness level. Bulk filter / coalescers are
necessary as a final filter to achieve the
recommended cleanliness level.
• Install desiccant type breathers of 4 µm or less
absolute efficiency with the ability to remove water
on bulk storage tanks.
• Follow proper practices of fuel transportation.
Filtration from the storage tank to the application
promotes the delivery of clean fuel. Fuel filtration
can be installed at each transport stage to keep
the fuel clean.
• Cover, protect, and ensure cleanliness of all
connection hoses, fittings, and dispensing
nozzles.
Consult your local Perkins distributor for additional
information on Perkins designed and produced
filtration products.

General Coolant Information
NOTICE
Never add coolant to an overheated engine. Engine
damage could result. Allow the engine to cool first.
NOTICE
If the engine is to be stored in, or shipped to an area
with below freezing temperatures, the cooling system
must be either protected to the lowest outside tem-
perature or drained completely to prevent damage.
NOTICE
Frequently check the specific gravity of the coolant
for proper freeze protection or for anti-boil protection.
Clean the cooling system for the following reasons:
• Contamination of the cooling system
• Overheating of the engine
• Foaming of the coolant
NOTICE
Never operate an engine without water temperature
regulators in the cooling system. Water temperature
regulators help to maintain the engine coolant at the
proper operating temperature. Cooling system prob-
lems can develop without water
regulators.
Many engine failures are related to the cooling
system. The following problems are related to cooling
system failures: Overheating, leakage of the water
pump and plugged radiators or heat exchangers.
These failures can be avoided with correct cooling
system maintenance. Cooling system maintenance is
as important as maintenance of the fuel system and
the lubrication system. Quality of the coolant is as
important as the quality of the fuel and the lubricating
oil.
Coolant is normally composed of three elements:
Water, additives, and glycol.
Water
Water is used in the cooling system to transfer heat.
