Show/hide table

At operating temperature, the hydraulic tank is hot and under pressure. Hot oil and components can cause personal injury. Do not allow hot oil or components to contact skin. Remove the filler cap only when the engine is stopped, and the filler cap is cool enough to touch with your bare hand. Remove the filler cap slowly in order to relieve pressure.

Show/hide table

Personal injury or death can result from escaping fluid under pressure. Escaping fluid under pressure, even a very small pin-hole size leak, can penetrate body tissue and cause serious injury and possible death. If fluid is injected into your skin, it must be treated immediately by a doctor familiar with this type of injury. Always use a board or cardboard when checking for a leak.

General Information Section

Introduction

The 284-0413 Bulk Fuel Filtration System is an integrated unit designed to remove particulates and water from diesel fuel. The maximum rated flow for this system is 190 LPM (50 GPM).

The system consists of one particulate pre-filter vessel, one fuel/water separator vessel, and a slug/differential control valve mounted on a base/drip pan assembly. Inlet and outlet ball valves are included on the system. All pressure containing components are welded carbon steel or ductile iron designed for use in all environments.

Pre-filter elements remove most of the solid particulate contamination. Coalescer elements and separator canisters remove water and filter the fuel. If restriction in the system (clogged filter elements or high water level) exceeds 172 kPa (25 psi), the slug control valve will close, stopping fuel flow.

Filters should be replaced and separator canisters cleaned every six months, or whenever differential pressure reaches 138 kPa (20 psi).

The slug valve also limits flow through the system to 190 LPM (50 GPM)maximum.

The system is equipped with a pressure relief valve located between the pre-filter vessel and water separator vessel. The pressure relief valve prevents the system from being overpressurized above 1034 kPa (150 psi).

Applications

The Caterpillar Bulk Fuel Filtration System is intended for use in any application where users store fuel for machines or engines. The filter unit is installed in series between the fuel pump on the fuel storage tank and the fueling station or fuel transport vehicle.

Note: The system does not require electrical power unless it is used in cold climates. Optional 307-0655 Electric Heaters (120 V), or 307-2569 Electric Heaters (220 V) are available for cold climates where water removed from the fuel may freeze.

Perform the Start-up procedure after replacing filter elements, or any other maintenance where the bulk fuel filtration system is opened.

For step by step information, refer to Start-up Procedure in the Operation Section of this manual.

Slug Valve Reset

Differential fluid pressure above 172 kPa (25 psi) caused by filter element restrictions will result in the slug valve closing, and stopping all fuel flow through the bulk fuel filtration system. Before refueling can resume, do the following:

1. Turn OFF the fuel supply pump.
