The pumped liquid may contain particles up to a size
which corresponds to the openings in the strainer.
The Solid pump is an electric submersible sludge pump
intended for continuous operation. Solid is designed to
handle contaminated water and water mixed with sand
and gravel.

Installation
Pump installation
Run the cables so that they do not have any sharp
bends and are not pinched.
Connect the discharge connection and motor cable.
See “electrical connections”.
Lower the pump into the sump.
Place the pump on a base which will prevent it from
sinking into a soft sump bottom. Alternatively, the pump
can be suspended by its handle just above the sump
bottom.
NOTE!
Where required by local authori-
ties an acceptable motor-circuit
switch or other disconnecting
device shall be provided at the
time of installation.
NOTE!
At certain installations and oper-
ation points on the pump curve
the noise level 70 dB, or for the
actual pump specied noise
level, can be exceeded.
Installation, care and maintenance Micro, Macro, Solid

Start and stop of the pump at different water levels may
be manual or automatic. If automatic start and stop is
required, a level regulator can be ordered (as option).
Level regulators are available for both 50Hz and 60Hz
markets.
The level regulator can be set at different operating lev-
els by adjusting the length of cable. A clamping bracket
situated below the lifting handle holds the level regulator
cable in place.
If continuous pumping is required at any time the level
regulator can be placed in a special rubber bracket on
the lifting handle thus eliminating the level regulator
function.
Level regulators

OFF
WARNING!
Always disconnect the power
supply before mounting or dis-
mounting the cable or/and the
level regulator. Risk for electrical
shock.
Earth continuity test
When performing the earth continuity test, measure be-
tween the earth wire in the motor cable and one of the
screws securing the strainer. See picture below.
Check that the mains voltage and frequence agree with
the specications on the pump data plate.
Make sure that the pump is correctly earthed (ground-
ed).
Electrical connections
WARNING!
All electrical equipment must
be earthed (grounded). This ap-
plies to both pump equipment
and any monitoring equipment.
Failure to heed this warning may
cause a lethal accident. Make
sure that the earth (ground) lead
is correctly connected by test-
ing it.
WARNING!
All electrical work shall be car-
ried out under the supervision of
an authorized electrician.
Local codes and regulations
shall be complied with.

WARNING!
If persons are likely to come into physical contact with the pump or pumped media (liq-
uid), e.g on construction sites or farms etc, the earthed (grounded) socket must have
an additional earth-(ground-)fault protection device (GFI) connected. When pumping
near a lake (jetties, beaches, ponds and fountains etc) a safety-distance of at least 20 m
(65 ft) between the person and the pump is applicable. The pump must never be placed
directly into a swimming pool. If used in connection with swiming pools, special safety
regulations apply.
WARNING!
Make sure that the gland-sleeve is correctly earthed (grounded) according to the wiring
diagram.
NOTE!
The two earth (ground) leads in the pump are connected via the same connector to
earth (ground).

Operation
Before starting
Check the oil level in the oil casing.
Remove the fuses or open the circuit breaker and check
that the impeller can be rotated by hand.
Check that the monitoring equipment (if any) works.
Check the direction of rotation. The impeller shall rotate
clockwise, as viewed from above. When started, the
pump will jerk in the opposite direction to the direction in
which the impeller rotates. See the gure.
Starting jerk
Cleaning
If the pump has been running in very dirty water, let
it run for a while in clean water, or ush it through the
discharge connection. If clay, cement or other similar
dirt is left in the pump it may clog the impeller and seal,
preventing the pump from working.
During a longer period out of operation, the pump must
be test run every other month to prevent the mechanical
seals from sticking together.
WARNING!
Watch out for the starting jerk,
which can be powerful.
WARNING!
Always lift the pump by its carry-
ing handle or lifting eyes, never
by the motor cable or the hose.

Care and maintenance
Inspection
Regular inspection and preventive maintenance ensure
more reliable operation.
The pump should be inspected at least twice a year,
more frequently under severe operating conditions.
Tightening screws
During assembly or service of the pumps we recom-
mend that the screws be tightened to approximately
6-8 Nm (4.5-6 ft lbs).
Note!
Make sure that the cable gland-nut, strainer/pump hous-
ing securing screws and oil-plug screw are not tight-
ened too hard.
The tightening torque listed above ensures that the
parts are correctly fastened and that the pumps will
operate as intended.
WARNING!
Be sure to disconnect the power
supply before attempting in-
spection, as the pump may start
automatically.
WARNING!
Make sure that the gland-sleeve
is correctly earthed (grounded)
according to the wiring diagram.
NOTE!
The two earth (ground) leads
in the pump are connected via
the same connector to earth
(ground).
Lubricating screws
To maintain screw tightness use a little mineral oil on all
non-stainless screws (not synthetic lubricants!).
Note!
When using stainless steel screws on stainless steel
parts we recommend that Aral Degol GS 460 or Nation-
al Chemseal Thread-Eze lubricants be used to prevent
screws from seizing or getting stuck.
