Maintenance/service
Prior to maintenance or repair work, turn
off the pump and ensure that it is not tur-
ned on by unauthorised personnel.
In the event of high temperatures and high
system pressure, the pumps should be al-
lowed to cool down
Danger of liquid boi-
ling over! Risk of scalding!
If the motor head is separated from
the pump housing for servicing or re-
pair work, the O-ring situated bet-
ween the motor head and pump hou-
sing must be replace by a new one.
When refitting the motor head, make
sure the O-ring is positioned cor-
rectly.

Problems, Causes and Solutions
For problems, causes, and solutions see "Error /
Warning Messages" flow chart and the tables below.
The first column in the table lists the code numbers
shown by the display in the event of an error.
Most error displays disappear automatically once the
cause of the error has been remedied.
8.1
Error messages
An error has occurred. The pump shuts down, the error
LED (red permanent light) comes on. After 5 minutes
the pump switches on automatically. Only when the
same error occurs for the 6th time within 24 hours does
the pump shut down permanently, the SSM relay opens
and the PLR or LON interface forwards the error mes-
sage. Manual reset is necessary.
Exception:
With blocking code no.
"E10" and "E25" the unit immediately
shuts down on the first occurrence.
8.2
Warning messages
The problem (only
W
arning) is displayed, but the SSM
relay does not come into action. The pump continues
to run. The error can occur an infinite number of times.
The indicated operating condition should not be igno-
red for long periods of time. The cause of the error must
be removed.
Exception:
If errors "E04", and "E05"
remain for more than 5 minutes,
these are passed on as error readings
(see diagram).
