Failures, Possible Causes, Troubleshooting Guide

Problems / Defects
After switching on, the
signal light does not turn
on.
The unit works but under-
pressure in the distillation
chamber cannot be
reached.
After sucking off the air, the
flushing agent does not
flow.
During operation:
a) "H" blinks on display
b) "H" lights up on display
c) "E" lights up on display
d) "h" blinks on display
e) "h" lights up on display
The unit is connected to the
socket, but after having
pressed PB1- START
compressor does not work.
The signal light is lit up!
Low flushing output.
Possible Cause
Energy supply defect.
a) Leakage in connection or
leakage in flushing
components.
b) Outlet valve (pos. 5) on the
distillation chamber is open.
c) Defect in electromagnetic valve
on outlet oil separator.
a) Valves on hoses or on the
cylinder with SOLSTICE
are closed.
b) Defect in hoses interconnection
between the solvent cylinder
and the K572 unit.
a) The valves on hoses or on the
refrigerant cylinder on the
liquid inlet are closed.
b) Pressure has gone beyond
maximum level.
c) Defect in the heat detector.
d) Maximum pressure of filling of
cylinder with SOLSTICE
C exceeded.
e) Pressure in cylinder has gone
beyond maximum level.
Defect in the electrical accessory
of the compressor or defect in the
compressor.
a) Polluted filter in the sight glass
"OUT" pos. 6
b) Low nitrogen pressure in the
cylinder.

Suggested Solution
Check power cable, plug and
distribution circuit breaker.
a) Check all connections – hoses,
nuts and fittings. Close valves
on hoses. If defect remains there
is leakage in circuit to flush –
repair leakage.
b) Close valve.
c) Contact service center.
a) Open valves on hoses and on
®
PF-C the cylinder.
b) Verify the connection of the
hoses: inlet-outlet and liquid and
vapor outlets on the cylinder with
SOLSTICE
a) Open valves on hoses and the
refrigerant cylinder liquid inlet
with SOLSTICE
b) Press PB1 -START and purge
will continue.
c) Contact service center – see the
notification on page 21.
d) 1) Reduce the pressure in the
®
PF- solvent cylinder below 8 bar by
releasing the hose screw joint at
the gas valve (blue) of the
solvent cylinder.
2) Reduce the pressure in the
distillation chamber using the oil
discharge valve (pos. 5).
Discharge into a suitable vessel!
e) Press PB1- START and flushing
will continue.
Contact service center.
a) Clean the sight glass filter
(see point 7.4)
b) Fill some nitrogen in the solvent
cylinder to raise the pressure to 8
bar.Please consult your solvent
supplier.
