Filtering fluids in the bypass flow
1. Connect the filter unit to a power source.
2. Place the suction strainer in the tank of the machinery or equipment (e.g. hydraulic tank).
3. Place the discharge pipe in the tank of the machinery or equipment (e.g. hydraulic tank).
4. Turn the filter unit on at the ON/OFF switch (circuit breaker).
5. Check the oil flow on a possibly insufficient immersion depth of the suction hose in the oil tank.
6. Using the clogging indicator, check the element for clogging at operating temperature of the medium used.
7. Once the filtration is completed, pull the discharge hose out of the tank of the machinery or equipment (e.g. hydraulic tank) and
draw in air for a maximum of 15 seconds.
This returns residual oil from the filter housing and the lines above the oil level into the tank of the machinery or equipment via
the discharge hose.
8. Switch off the filter unit using the circuit breaker.
9. Clean the hoses and install plugs to their free ends. Re-attach the suction and the discharge hose at the appropriate brackets at
the filter unit.
9.2.1 Working with the additional return-suction set
1. Connect the filter unit to a power source.
2. Install the suction-return adapter in the oil tank.
3. Remove the plugs from the free ends of the suction and pressure hose.
4. Connect the suction and pressure hose to the appropriate quick couplings of the adapter.
5. Using the clogging indicator, check the element for clogging at operating temperature of the medium used.
6. Once the filtration is completed, pull the suction hose from the quick coupling and draw in air for a maximum of 15 seconds.
This returns residual oil from the filter housing and the lines above the oil level into the tank of the machinery via the discharge
hose.
7. Switch off the filter unit using the circuit breaker.
8. Clean the hoses and install plugs to their free ends. Re-attach the suction and the discharge hose at the appropriate brackets at
the filter unit.
9. Uninstall the suction-return adapter and attach it to the appropriate bracket at the filter unit.
NOTE
Off-line filtration in tank with only one available connection port
›
Use the additional suction-return set to allow installation of two hoses (suction and return) in one port.
