    • bar or less should be shown on the low-pressure manometer). The EkoFlush-K572 unit can only be transported by transportation means if its solvent cylinder is • disconnected and transported separately. The main unit can be transported on wheels (properly protected against moving), or laid down on its rear side leaning on its handle and wheels.

  • Page 3: Unit Description

    3. Unit Description The EkoFlush-K572 is a mobile flushing unit with wheels and rugged metal structure. The solvent cylinder required to operate the machine must have a two-way valve and must be filled ® only with the flushing agent SOLSTICE PF-C by HONEYWELL, pressurized with nitrogen at 8 bar.

  • Page 5: Main Principles And Interconnections

    6. Main principles and interconnections The circuit to flush must be tight, free from leaks and from internal blocks. IMPORTANT! Please check the absence of internal blocks by flowing some nitrogen or air through the circuit, before starting the flushing operations. The pressure of the solvent and the EkoFlush unit may not be sufficient to remove the blocks and the flushing operation will not be completed, resulting in loss of solvent.
  • Page 6 6.11 Check the oil level in the compressor sight-glass and refill if necessary. The level of the oil must be between those two lines, indicated in the picture below. Picture 2 - Sight-glass for compressor oil WARNING! Any claim for malfunctioning caused by lack of oil won’t be accepted!! 6.12 Connect the front panel of the EkoFlush K572 to the circuit to flush, as follows: inlet into the flushed circuit to “IN”...

  • Page 11 Remark : If the electric power is interrupted when the procedure at point 8.2 is in process (from the pressing of “START” until the first acoustic signal), LED 1 blinks after electric power has been renewed. You need to press PB 1 – START again to continue the program from the point it had stopped (the last active process step is repeated from its beginning).
  • Page 12 Open Picture 8 - Discharge of oil and dirt IMPORTANT NOTE 1) The low-pressure manometer (Picture , Pos. 16) – shows the pressure in the circuit being flushed. It does not show any overpressure in the distillation chamber. 2) Oil and sludge can also be discharged from the distillation chamber after the flushed circuit is disconnected.

  • Page 13: Completing Flushing

    7) The maximum capacity of the distillation chamber for oil and residues is about 1 liter. If during the flushing this capacity is filled with contaminants, LED7 (Distillation Chamber Full) will not switch off and the process can “freeze”. It is necessary to discharge the distillation chamber, but first it´s necessary to add pressure to chamber, so that oil and particles can flow out through the drain valve.

  • Page 14: Exchange Of Solstice Pf-C Solvent

    Exchange of SOLSTICE PF-C solvent ® Honeywell recommends to replace the flushing solvent SOLSTICE PF-C after 20 flushing operations. The real efficiency in the purification of the flushing solvent depends on the type and level of the fouling of the cleaned equipment.
  • Page 15 After this phase, a triple beep will be heard, the compressor switches off, the display will show a blinking „o“ and the LED „START“ will lighten up. It’s time now to discharge the contaminants (oil and particles) from the distillation chamber, but first it´s necessary to add pressure to chamber, so that oil and particles can flow out through the drain valve.

  • Page 16: Oil Change, Adding Oil

    12.1 Oil change New complete filling is 0,4 liters of recomended oil. During filling, it is necessary to place a sufficient volume of oil in a suitable container under the oil inlet (pos. 33), so that the hose fitted to the valve reaches the bottom of the vessel.

  • Page 17: Waste Disposal

    ® Waste Disposal (SOLSTICE PF-C flushing liquid and waste product) A cylinder of SOLSTICE PF-C can be used to flush efficiently a maximum of 20 circuits, after which you can still use the solvent for a final Open-flush operation (vented to air). Please return the empty cylinder of SOLSTICE PF-C to your local supplier.
