A
Caution!
The pump must not be activated more than
20 times an hour, as this could cause the mo-
tor to overheat.
A
Danger from faulty pump!
Take appropriate measures to ensure that
pump faults do not cause consequential
damage through flooding of rooms. This must
be ensured, for example, through installation
of an alarm system or a reserve pump.
A
Danger!
Do not let the pump run against a closed
pump line.
5.2
Minimum water level
Continuous operation:
The pump must be completely submerged for
continuous operation to take place.
Restricted operation:
Only restricted operation is possible if the
pump is not fully submerged. Note the follow-
ing restrictions:
A
Risk of material damage from dry
running of pump!
The pump can overheat and become dam-
aged as the cooling function of the pumped
medium is reduced. The thermal switch will
react.
Suction operation for a short period only
(2-3 mins).
Monitor the pump's operation during suc-
tioning.
5.3
Pump capacity curve
The pump capacity curve indicates the flow
volume, depending on the delivery head.
A
Danger!
Unplug before maintaining or cleaning.
Repair and maintenance work other than de-
scribed in this section should only be carried
out by qualified specialists.
6.1
Regular care
Regular care is required for the pump to func-
tion perfectly at all times. This also applies if
the pump is not switched on for extended pe-
riods of time (e.g. during operation in soaka-
ways).
Cleaning the pump
1. Rinse pump with clean water. Remove
persistent marks, e.g. algae deposits, with
brush and dishwashing liquid.
2. To rinse the inside of the pump:
dip pump into a container of clean water
and switch on briefly.
6.2
Pump storage
A
Caution!
Frost damages the pump and accesso-
ries as both always contain water!
If there is a danger of frost, disassemble
pump and accessories and store in frost-
free conditions.
6.3
Device maintenance (only for
SP 28-50 S Inox, DP 28-10 S
Inox)
A
Caution!
Lubricant may leak from the pump if the seals
are defective, causing contamination of the
liquid being pumped.
Although the lubricant contained in the sub-
mersible pump for dirty water is non-toxic, it
can alter the water properties.
A
Danger!
Maintenance work must only ever be car-
ried out by qualified, specially trained
staff.
After 4,000 to max. 8,000 hours of op-
eration, and in any case at least once a year,
the quantity and quality of the oil in the oil res-
ervoir must be checked.
