Error 4:
Unable to
drain residue
Automatic drainage
of residue active:
The residue in the
evaporating flask can
no longer be drained.
a. Suction and pressure
height of the residue
pump are exceeded.
The flask sensor
triggers safe
shutdown and
initiates the
final process (in
the event of an
error). The error
code appears.
a. Compare suction
and pressure height
of the residue pump
with the data of the
maximumsuction
and pressure height
given in chapter
„Technical data” and
adjust the heights
correspondingly.
b. Flow rate of the
residue pump is
set too low.
b. Adjust the flow rate
of the residue pump
using the rotary
knob to 100 %.
c. The residue
pump is dirty.
c. Clean the residue
pump (see chapter
entitled „Cleaning”
- „Circuit and
flask sensor” -
„Residue circuit”).
d. The viscosity of the
medium is too high.
d. Adjust the viscosity
of the medium for
the new evapo-
ration process.
e. Cable break in the
flask sensor.
e. Contact Technical
Service.
f. The residue pump is
defective. f. Contact Technical
Service.
g. PTFE tube Ø 8 mm
for the automatic
drainage of residue
(only on Disti-
matic including
automatic drainage
of residue)incor-
rectly positioned.
g. Correct the position
of the PTFE tube
Ø 8 mm for the
automatic drainage
of residue (see
chapter „Instal-
lation”).
