Startup
The
hose
or
pipe
connections,
particularly
on
the
suction
side,
must
not
leak.
If
hoses
are
used,
a
spiral
hose
must
be
used
on
the
suction
side
to
prevent
the
hose
from
collapsing
due
to
the
vacuum
generated.
Caution
The
pump
must
be
filled
with
the
liquid
to
be
pumped
before
startup.
Risk
of
dry
running.
If
pipes
are
used,
fit
flexible
connections
between
pump
and
pipes.
Make
sure
that
the
pump
and
its
connections
are
not
stressed
by
the
pipework.
The
system
suction
head
must
not
be
greater
than
the
suction
head
stated
for
the
pump.
The
nominal
pipe
diameter
should
be
the
same
as
that
of
the
pump
ports
or
larger.
Clogging
of
the
water
intake
by
muddy
groundwater
can
be
prevented
by
raising
the
strainer.
10.1
Priming
Prime
the
pump
by
removing
the
priming
plug
or
via
the
discharge
port.
Fit
and
tighten
the
priming
plug.
Do
not
forget
the
seal.

Checking
the
direction
of
rotation
Note
To
ensure
that
the
strainer
is
suspended
vertically
in
the
water,
lower
the
strainer
into
the
water
in
a
wicker
basket
or
lay
the
suction
hose
over
a
branch.
Fill
the
pump
with
liquid
prior
to
checking
the
direction
of
rotation.
The
direction
of
rotation
of
the
motor/engine
must
as
shown
by
the
arrow
on
the
pump.

Electrical
connection
Warning
Disconnect
the
power
supply
to
the
pump
before
removing
the
terminal
box
cover
and
before
any
dismantling
of
the
pump.
Caution
The
pump
must
only
run
for
a
short
period.
If
necessary,
change
the
direction
of
rotation
by
interchanging
two
phases.
10.3
Starting
the
pump
The
electrical
installation
should
be
carried
out
by
an
authorised
person
in
accordance
with
local
regulations
and
the
wiring
diagram
in
the
terminal
box
cover.
Caution
Do
not
start
the
pump
until
it
has
been
filled
with
liquid.
The
pump
must
not
run
against
a
closed
discharge
The
pump
must
be
fused
in
the
building's
electrical
installation
and
be
connected
via
an
external
switch.
Check
that
the
supply
voltage
and
frequency
correspond
to
the
values
stated
on
the
nameplate.
9.1
Overload
protection
Motors
with
built-in
sensors
for
connection
to
an
external
control
circuit
are
available
on
request.
The
sensors
are
bimetallic
thermal
switches
or
thermistors
(PTC).
Thermal
switches
can
be
connected
directly
to
an
external
control
circuit
to
protect
the
motor
against
steady
overload
(TP
111
according
to
IEC
34-11).
The
motor
must
be
equipped
with
a
protection
device
for
protection
against
stalling.
The
thermal
switches
are
capable
of
switching
1.5
A
at
250
VAC.
The
thermistor
must
be
connected
to
an
external
amplifying
relay
connected
to
the
control
circuit.
In
this
case,
the
motor
is
protected
against
rapid
and
steady
overload
(TP
111
according
to
IEC
34-11).
The
thermistors
are
in
accordance
with
DIN
44
082.
When
repairing
motors
incorporating
thermal
valve.
Start
the
petrol
or
diesel
engine
in
accordance
with
the
operating
instructions
of
the
engine.
10.4
Operation
Warning
The
pump
must
not
run
against
a
closed
discharge
valve
due
to
the
risk
of
scalding
hot
water
caused
by
conversion
of
motor
energy
into
heat
in
the
pump.
10.5
Maximum
number
of
starts
per
hour
Motor
smaller
than
4
kW:
100.
Other
motors:
20.
Do
not
operate
combustion
engines
continually
at
full
load.
Caution
switches
(Klixon),
make
sure
that
the
motor
cannot
start
automatically
after
cooling.
