3. INSTALLATION
AND
ASSEMBLY
GENERAL
Ͳ
Our
pumps
may
only
be
assembled
and
installed
in
pools
or
ponds
that
are
compliant
with
HD
384.7.702.Should
you
have
any
doubts,
please
consult
your
specialist.
Ͳ
Fit
the
pump
horizontally
due
to
the
pre
Ͳ
filter.
The
pumps
are
fitted
with
a
pre
Ͳ
filter
with
a
basket
inside
to
collect
any
large
particles,
as
they
may
damage
the
hydraulic
part
inside
the
pump.
Ͳ
All
pumps
are
fitted
with
a
foot
with
two
holes
in
it
to
anchor
it
to
the
ground.
(Fig
1).
PIPING
Ͳ
To
connect
the
piping,
glue
the
pipes
and
the
connectors,
supplied
together
with
the
pump;
the
fitting
connections
to
the
suction
and
return
ports
on
the
pump
are
threaded
and
include
seals
to
prevent
water
loss
(Fig.
2).
Ͳ
Fit
the
return
pipes
completely
perpendicular
and
centred
in
relation
to
the
port
to
be
connected
to
prevent
the
pump
and
the
pipe
from
being
subjected
to
external
stress
that,
apart
from
making
fitting
difficult,
could
break
them
(Fig.
2).
Ͳ
Fit
the
suction
piping
on
a
slight
2%
slope
towards
the
pump
to
avoid
the
formation
of
air
pockets
(Fig.
2).
Ͳ
To
ensure
the
pump
works
correctly,
prime
the
pump
pre
Ͳ
filter
until
water
rises
up
through
the
suction
pipe
(Fig.
3).
LOCATION
Ͳ
Fit
the
pump
underneath
the
water
level
in
the
pool
to
improve
pump
performance.
Ͳ
Where
a
self
Ͳ
priming
pump
is
to
be
fitted
above
the
water
level,
the
difference
in
height
must
be
no
more
than
2
metres
(Fig.
4),
ensuring
that
the
suction
pipe
is
as
short
as
possible
as
a
long
pipe
would
increase
drainage
times
and
load
losses
in
the
installation.
Ͳ
Make
sure
that
the
pump
is
safe
from
possible
flooding
and
receives
dry
ventilation.
ELECTRIC
INSTALLATION
Ͳ
The
electric
installation
must
include
a
multiple
separation
system
with
contact
openings
of
at
least
3
mm.
Ͳ
Use
a
rigid
cable
to
connect
to
the
mains.
If
you
use
a
flexible
cable
to
connect
to
the
mains,
it
must
have
cable
lugs
to
connect
to
the
terminals
of
the
pump
motor.
Ͳ
With
any
type
of
pump,
0.03
A
differential
protection
must
be
fitted
for
electricity
leakage
protection
(indicated
on
the
diagrams).
Ͳ
Adjust
the
value
of
the
thermal
relay
appropriately
depending
on
the
pump
current.
For
pumps
with
a
single
phase
motor:
x
Thermal
protection
is
incorporated.
Installation
with
a
switch
is
sufficient,
in
line
with
the
“Main
connections”
diagram.
x
Use
a
motor
guard
with
magneto
Ͳ
thermal
protection.
x
The
adjustment
data
for
the
thermal
relay
is
to
be
used
as
a
guideline,
as
the
motor
is
already
fitted
with
protection.
