Please
note
that
the
pump
needs
to
be
properly
primed
in
order
to
achieve
a
stable
flow
and
low
pulsation.
A
minimum
flow
rate
is
required
for
the
priming
(complete
removal
from
air
inside
the
pump
chamber).
The
following
table
indicates
the
minimum
required
pump
speed
for
water
with
<0.5
bar
discharge
pressure.
Please
note
that
these
values
may
depend
on
the
installation.
The
duration
of
the
vent
process
at
a
given
min.
pump
speed
is
generally
from
5
to
10
seconds.

The
QT30
pump
unit
is
mounted
on
a
stainless
steel
base
plate.
The
standard
version
of
the
pump
sizes
QT10
and
QT20
must
be
fixed
by
using
suitable
screwing.
QuattroTec
pumps
are
self
‐
priming
and
can
run
dry.
Inside
the
pump
chamber
there
are
no
rotating
parts
that
might
cause
heating
up
of
the
product
or
shed
particles.
Before
start
‐
up
of
the
pump
anyone
should
acquaint
oneself
with
the
explanations
of
the
chapter
troubleshooting
(see
page
27).
Only
by
this
the
defect
quickly
can
be
realized
and
eliminated
in
case
of
trouble.
Problems
which
cannot
be
solved
or
with
an
unknown
reason
should
be
passed
on
to
the
manufacturer.
Prior
to
each
use
we
recommend
to
flush
the
pump
with
a
proper
fluid.
Before
using
your
pump
in
your
process
perform
a
test
run
to
get
used
to
the
specific
properties
of
the
pump.
If
hoses
were
used
in
the
suction
line,
make
sure
that
they
do
not
collapse
due
to
the
negative
pressure..
When
installing
the
pump
please
consider
that
around
the
pump
enough
space
is
available
for
operation
and
maintenance.
Pay
attention
to
the
required
space
needed
for
assembly
and
disassembly
of
the
pump
chamber.
During
start
‐
up
pay
attention
to
the
warning
and
safety
instructions
of
this
manual.
