Honeywell EkoFlush-K572 User's Operating Manual 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).
The same happens if PB 5 – END is pressed (compressor is stopped, LED 1 blinks). To continue the program,
press PB 1 – START.
8.3. Completing the flushing.
8.3.1. Press PB 5 – END.
If LED 5 blinks and the pressure on the low-
pressure manometer (pos. 16) is lower than – 0,5
bar. (see the note 7.4)
8.4 Discharge of oil and sludge from the distillation
chamber
8.4.1 Press PB 4 – MAN.PURGE once. Nitrogen is sent
to the distillation chamber for 20s.
8.4.2 Press PB 4 - MAN.PURGE a second time and
reduce the pressure to 0,5 – 0,7 bar. The
compressor is on.
8.4.3 Press PB 5 – END to turn off the compressor.
8.4.4 Open the discharge valve of the distillation chamber
(see Picture 8) and discharge the oil and the sludge
into a container.
Once the oil stops flowing out and nitrogen begins
to get released, close the valve.
NOTE
In the flushed circuits an overpressure of about 0,3 bar will remain.
The cycle can be finished with the work flow described at point 8.4.8.
To reduce the nitrogen loss it is recommended to follow the work flow described in points 8.4.5 and 8.4.6.
The procedure will be completed with point 8.4.8.
8.4.5 Open the nitrogen supply of the distillation chamber
for 20s by pushing PB 4 – MAN.PURGE once.
8.4.6 Turn on the compressor by pushing PB 4 –
MAN.PURGE a second time and reduce the
pressure to atmospheric pressure level (0.0 bar on
the LP manometer – Picture 4, Pos.16).
8.4.7 Turn off the compressor by pushing PB 5 – END.
NOTE
In order to reduce any losses of SOLSTICE
is recommended to wait for an under-pressure between -0,5 and -0,8.
Once that level is reached, press PB5 – END to switch off the compressor.
We recommend to bring the flushed circuit to atmospheric pressure or slight overpressure using pure
nitrogen (it'll prevent moisture to enter the circuit).
8.4.8 Turn off the main switch (Picture 4, Pos.31)
