Problems / Defects Possible Cause Suggested Solution
After switching on, the
signal light does not light
up. Energy supply defect. Check inlet flex, plug and
distribution circuit breaker.
Unit runs but under-
pressure cannot be reached
in the distillation chamber. 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) Check all connections – hoses,
nuts and fittings. Close hoses
valves. If defect remains there
is leakage in flushed
components – repair leakage.
b) Close.
c) Contact service centre.
After sucking off air, the
flushing agent does not
flow. a) Closed valves on hoses or on
the refrigerant cylinder with
SOLSTICE
®
PF-C.
b) Defect in hoses interconnection
between the refrigerant cylinder
and flushing unit.
a) Check openings of valves.
b) Examine hoses connections /
inlet-outlet and liquid and vapour
outlet on the cylinder with
SOLSTICE
®
PF.
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 a) Closed valves on hoses or on
the refrigerant cylinder on the
liquid inlet.
b) Pressure has fallen below
maximum level.
c) Defect in the heat detector.
d) Maximum pressure of filling of
cylinder with SOLSTICE
®
PF-
C exceeded.
e) Pressure in cylinder has fallen
below maximum level.
a) Check valves openings on hoses
and the refrigerant cylinder liquid
inlet with SOLSTICE
®
PF-C.
b) Press “START” and purge will
continue.
c) Contact service centre – see the
notification on page 19.
d) 1) Reduce the pressure in the
refrigerant cylinder below 8 bar
by releasing the hose screw joint
at the gas valve of the refrigerant
cylinder.
2) Reduce the pressure in the
distillation chamber using the oil
discharge valve (pos. 5).
Discharge into a suitable vessel!
e) Press “START” and flushing will
continue.
Unit is connected to the
socket, but compressor
after start does not run. The
signal light is lit up! Defect in the electrical accessory
of the compressor or defect in the
compressor. Contact service centre.
Reduction of the flushing
output. a) Polluted filter in the sight glass
“OUT” pos. 6
b) Low nitrogen pressure in the
cylinder.
a) Cleaning of the sight glass filter
(see point 7.4)
b) Fill up nitrogen in the refrigerant
cylinder at the given pressure.
