1. INTRODUCTION

2. GENERAL DESCRIPTION

3. PURPOSE

4. SAFETY REGULATIONS, RISKS AND WARNINGS

This NTF (OLFS) off-line filtration system can be applied for the re-circulation of fluids in any hydraulic,

lubrication, transmission and fuel system. The unit has been fitted with a dedicated motor and pump, thus

ensuring that system pressure and specifications stay within factory prescribed limits. The purpose of the

OLFS is to recirculate the fluid by pumping it from a reservoir or reservoir through the filter and return it to the

reservoir. Cleaner oil leads to less malfunctions and cost savings.

The OLFS has been modulary fitted on a manifold, in which all oil channels have been integrated, thereby

minimizing the risk of oil leaks. The main advantage of the OLFS unit is that the filtration process takes place

under constant flow and pressure. Because of this the efficiency is 10 times higher than of any in-line filter

system. The results are:

Cleaner oil

Less malfunctions of the system the OLFS is fitted on.

Less wear of the system the OLFS is fitted on.

Prolonged life time of the system the OLFS is fitted on.

Less oil consumption, better for the environment.

The OLFS is marked with

The OLFS has been constructed according to CE norm machinery directive

This OLFS filter system is specially designed for filtration of hydraulic and lubrication oil reservoirs. It can also

be applied to fuel systems. When filtering fuel it is highly recommended to install a water separator in the

suction line. As NTF filter cartridges are hygroscopic the water content in the fuel may cause the elements to

saturate prematurely.

Please keep the following in mind when installing the OLFS unit:

Before assembling, connecting or servicing the OLFS unit, make sure that the application, on which

the OLFS will be installed is safe to work on. If necessary, shut off electricity. Make sure that there is

no oil pressure on the oil lines. If there is pressure, bring it down to 0 Bar.

Use the proper hoses for the application (hydraulic or fuel).

Do not use hoses for low-pressure

applications.

Make sure that the return line from the OLFS to the tank has no pressure. Do

not use existing

return lines.

Use the proper connector materials for the application (hydraulic or fuel). Do not use tape or sealing

liquid!

When starting up the system, make sure that the motor is rotating in the proper direction (clockwise).

When replacing the filter elements or when spillage occurs, use the personal safety equipment, as

prescribed in the Material Safety Data Sheet of the fluid.

5. OPERATING INSTRUCTIONS (INCLUDING MOTOR)

6. TRANSPORT, STORAGE AND DISPOSAL

Installation of this unit is only allowed to certified professionals engineers. In

case of warranty claims certificates will be requested

The unit must be properly grounded to avoid any static electricity

Before switching on the unit ALWAYS check that there are no restrictions in

the suction and return line. In case valves are installed in suction and or return

line of the filter unit these valves should be opened before the unit is switched

on.

When replacing the filter elements or when spillage occurs, use the personal

safety equipment, as prescribed in the Material Safety Data Sheet. Check also

personal safety regulations at site.

The filter is functional when the motor is running. Installation should be done by certified electrical engineers.

The user is responsible for the proper electrical wiring and installation of the filter unit. User must determine the

appropriate guidelines as to when and how switch the unit to on and off. Additional information with regard to

this point can be found under no.13

This OLFS-unit has been carefully packed to avoid damage during normal transport. Should your OLFS unit

arrive damaged, please take pictures of the occured damages and send these with a description to your NTF

dealer, so the damaged unit can quickly be replaced. There are no further special requirements for transport or

storage.

When the OLFS unit or filter element is disposed off, the local regulations for disposing chemical waste should

be taken into account.

7. INSTALLATION AND ASSEMBLY

Before assembling and connecting the OLFS unit, make sure that the machine, on which the OLFS

will be installed is safe to work on. If necessary, shut down electricity. Make sure that there is no

system pressure. If there is pressure, bring it down to 0 Bar.

Mount the filter system on a vibration free spot.

Keep hoses as short as possible. Do not bend or tense hoses.

Make sure there is enough space after installation to be to have easy access for cartridge changes.

Assure that the pressure gauge is properly accessible.

The filter system should be installed in such a manner that enough space is available to connect oil

analysis equipment to the sample connections.

Connecting the OLFS unit must be carried out by qualified personnel.

Assemble a connector to the suction side of the pump and the return channel of the manifold. Fit hose

or pipe to these connectors.

Create a suction hose from the tank to the pump of the OLFS unit. Ensure that the suction port in the

tank is always beneath the minimum level of the fluid.

To make the suction line (inside diameter 10 mm) use the proper hoses for the application (hydraulic

or fuel) equipped with the appropriate connectors.

Do not use hoses for low-pressure applications.

The return port of the manifold to the tank must be connected pressureless. Do not use existing return

lines. Ensure the returned oil flows back into the tank below the minimum fluid level. Locate the return

port on the tank in such a manner that oil in the tank circulates properly (suction and return port not to

close together).

To make the return line (inside diameter 19 mm) use the proper hoses for the application (hydraulic or

fuel) equipped with the appropriate connectors. Do not use hoses for low-pressure applications. Keep

the return line as short as possible!

Use the proper connector materials for the application (hydraulic or fuel). Do not use tape or sealing

liquid!

Make sure that electrical connection complies with local installation- and safety regulations.

Before switching on the unit ALWAYS check that there are no restrictions in the suction and

return line.

In case valves are installed in suction and or return line of the filter unit these valves should be

opened before the unit is switched on.

When starting the system, make sure that the motor is rotating in the proper direction (clockwise). This

direction is also marked with an arrow on the motor. Checking the rotation direction can easily be done

by looking at the cooling fan at the rear end of the motor. Rotation direction depends on wiring

connections as shown under point 12

“

Technical specifications motor

”.

Prevent the access of any

water, dirt or accessive dust in the electric motor.

After starting the system and after the first hour of operation, check for any leaks or abnormal sounds

in the system. When the system shows leaks or any abnormal sounds, switch it off immediately. The

cause should be determined and remedied before any further operation.

When using the minimess connectors on the manifold, ensure that the return line is pressureless.

8. MAINTENANCE INSTRUCTIONS

The required maintenance on an OLFS-unit consists of the timely and properly changing of the filter elements.

Changing the filter elements should be done as follows:

Only use original NTF

filter cartridges.

Only use the supplied spare parts.

The filter cartridge must be replaced when the pressure gauge indicates 5,0 Bar at operating

temperature, or every 6 months, whichever comes first.

Check for pressure on the tank. Relief the pressure of the system when necessary.

Ensure that the filter system is pressure-less when replacing the filter cartridge.

Remove the filter cartridge and spare O-ring from the packaging.

Remove the lid from the system and take out the pressure plate with spring.

Remove the used filter cartridge and place it in the plastic bag for proper disposal. Place the new

filter cartridge in the filter system and place the pressure plate with spring back on the filter cartridge.

Replace the O-ring, clean the sealing surfaces and put the lid back on the filter system. Tighten the

inner hexagon bolts with a torque of minimal 9 Nm and maximal 12 Nm.

Start the system until it has reached its operating temperature and check for leakages.

Check the oil level in the system and top up the necessary quantity, if necessary.

Check if the oil runs through the filter properly. If the hoses and the filter housing warm up, the filter

system operates properly
