Problems / Defects Possible Cause Suggested Solution
The pressure on LP
manometer is lower than
minus 0.5 bar, but in the
flushed circuit there is still
liquid SOLSTICE
®
PF-C.
The circuit is clogged. Close the valves on the hoses at flushing unit.
(on the hoses interconnecting flushing unit and
circuit to flush – see Picture 5)
Disconnect them and then connect them
reversed (IN / OUT).
Open valves on hoses.
To recover SOLSTICE
® PF-C from the circuit
press MAN. PURGE (PB4).
By first pressing of PB4 the nitrogen is filling
(20s), by second pressing the recovery is
starting (compressor). Wait for about 10
minutes.
Switch off the compressor by pressing PB5.
If an under-pressure is not reached, repeat the
procedure.
EkoFlush unit runs, but
required under-pressure
cannot be reached.
Compressor doesn’t work. Compressor failure. After completing the flushing procedure, wait
for an acoustic signal, then push the PB5-
END button and switch off the unit. Close all
valves on hoses and disconnect hoses from
cylinder and EkoFlush unit. BEWARE: The
EkoFlush unit can contain small quantity of
liquid SOLSTICE
®
PF-C.
Use a recovery machine to recover
SOLSTICE
® PF-C from the circuit to the
solvent cylinder. The Inlet of recovery machine
must be connected to outlet of the circuit to be
flushed. The Outlet of the recovery machine
must be connected to the cylinder valve –
liquid phase - RED. Follow the instructions in
the manual of the recovery machine. Use a
scale to avoid the overfilling of the solvent
cylinder.
Notification:
If any heating sensor failure occurs during the flushing process ("E" lights up on the display), the
flushing cycle will be finished until the discharging of the distillation chamber and the next flushing will
not be possible.
The time needed to complete the flushing cycle will be longer because the distillation will be running at
a lower temperature.
When the pressure on the low-pressure manometer reaches -0,5 to -0,7 bar, turn off the device and
contact the service center.
Checking EkoFlush function
•
Connect inlet and outlet of EkoFlush with one hose, if a hose with a valve, please open it
(Picture 10 - with open valve)
•
Turn on the unit and select 1 flushing cycle.
Open the valves of a cylinder with SOLSTICE
®
PF-C
•
Press START
The whole cycle will pass, until sucking off in under-pressure, charging with SOLSTICE
®
PF-C (see
sight glasses), blowing-out by nitrogen, final recovery (it takes about 20 minutes)
•
If the EkoFlush ends in under-pressure, the unit is OK, the problem is out of the unit
o
If the cycle will not run as described above, the unit has a problem.
Please contact your supplier.
Please prepare information in which phase the unit stopped, state of gauges and which
LED blinks or lights
