Grounding
Instructions
This
product
must
be
grounded.
In
the
event
of
an
electrical short
circuit,
grounding
reduces
the
risk
of
electric
shock
by
providing
an
escape
wire
for
the
electric
current.
This
product
is
equipped
with
a
cord
having
a
grounding
wire with
an
appropriate grounding
plug.
The
plug
must
be
plugged
into
an
outlet that
is
properly
installed
and
grounded
in
accordance
with
all
local
codes
and
ordinances.
WARNING!
Improper installation of
the
grounding
plug
is
able
to
result
in
a
risk
of
electric
shock.
When
repair or
replacement
of
the
cord
or
plug
is
required,
do
not
connect
the
grounding
wire
to
either
flat
blade
terminal.
The
wire with
insulation

are
not
completely
understood,
or
when
in
doubt
as
to
whether
the

is
properly grounded.
Do
not
modify
the
plug
provided;
if
it does
not
fit
the
outlet,
have
the
proper outlet
installed
by
a
qualified
electrician.

piping
and
T
pieces.
Choose
fittings
and
pipe
sizes
that
suit
your installation
requirements,
ensure
all pipes
are
secured
with
clips.
Using
larger
bore
pipe,
and
avoiding
sharp
bends
will
improve performance.
Use
new
and
sufficiently
large
aerators
with
enough
discharge
capacity.

Ensure
the pump
can
discharge
sufficient
air
at all times, never
close
off
backflow of
water
into
the
pump,
install
the
pump
above
water
level,
If
this
is
not
possible,
a
non-return
or
check
valve
must
be
used
in
the
outlet
pipe.
Any
additional
fittings
or
equipment
attached
to
the
pump
airline
must
be
safely installed
without
risk
of
harm
to
others.
5)
Locating
The
Blower
A
WARNING’
Do
not
place
the
pump
where
it
might
come
into
contact
with
liquids,
or
near
flammable or
other
dangerous
materials
or
objects.
Never
immerse
the
pump
in
water.
Sunlight
heat
may
shorten
diaphragm
and valve life,
therefore
place
in
a
shaded
area
where
possible.
Dust
may block
the
filter
which
will
cause
overheating
and
result
in
shortening
diaphragm
and valve
life.
The
electricity
supply
must
be
grounded
to
protect
the
operator
from
electric
shock.
If
the
pump
falls into
the
water,
unplug
from
the electricity
supply
before
attempting
to
retrieve
it.
Let
qualified
technicians
check
the
pump before reconnecting
it.
Before
installation,
and
periodically,
examine
the
power
cord.
If it
is
damaged
it
must
be
replaced
by
the
supplier
or
service
agent
or
similarly
qualified
person
in
order
to
avoid
a
hazard.
6)
High
Temperature
Use
If
the
temperature
may
reach
over
120°F,
a
cooling fan
with
ventilation
is
recommended.
During
high
temperatures
the
pump
will
turn
off
~‘ia
the
thermal
cutout.
The
pump
will
automatically
restart
when
cooled.
If
your
septic
system
has
been
without air
for
a
few
days,
a
build
up
of
solid
around
the
airstone/diffuser
can
cause
a
build
up
of
back
pressure
which
will
overheat
the pump,
causing
the
thermal
cutout
to
stop
the
pump.
The
pump
will
restart
after
it
cools
down
and
blockages
are
often
cleared
after
a
couple
of
goes.
7)
Connection
The
exhaust
port
should
be
connected
with
the
L-joint
hose
supplied.
If
using
a
smaller
diameter
pipe,
excess
pressure and
overheating
may
occur,
shortening
the
diaphragm
and
valve
life.
A
hose
c
ip
should
be
used
to
secure
place
of
connection.
Plumbing
should
be
as
short
and
straight
as
possible,
if
over
33ft
I
1
Om
please
consult
your
distributor.
8)
Periodical
Maintenance
Any
dust
or
foreign
matter
entering
the
air
inlet
may
cause
abnormal
noise,
or
result
in
failure
of
the
pump.
Therefore,
clean
the
filter
element
at
least once
every
six
months,
frequency
will
depend
on
environment.
Product
must
always
be
disconnected
from
power
before
servicing.
Failure
to
do
so
could result
in
electrical
shock,
personal
injury
or
death.
9)
Filter
Element
Cleaning
•
With
a
screwdriver, lever the
plastic
filter
cover off.
•
Take
filter
out
and
clean
the
air
inlet,
filter
cover,
and
sponge
mounting
surface,
washing
with
clean
water
before drying
thoroughly
out
of
direct
sunlight.
•
Put
filter
back
in
and
replace
cover.
10)
Diaphragm
Replacement
A\WARNINGI
Ensure
pump
is
disconnected
from
mains
supply
before
servicing.
•
Loosen
the
four
screws
around
the
aluminium
upper
housing
and
take
housing
off.
•
Locate
pump
inside
housing.
•
Loosen
the
four
screws
either
side
and
remove the
air
chamber
cover.
•
Loosen
the nut
and
remove
the
chamber
block,
antistatic membrane
and
the
diaphragm.
•
Replace
diaphragm
making
sure
the
diaphragm
fits
exactly
to the slot
of
the
air
chamber.
•
Install
all
parts
by
counter
steps.
•
Put
aluminium
cover
on
and
secure
the
four
screws
firmly.
The
most
common
cause
of
premature
diaphragm
failure
is
excessive
back
pressure
or
overheating.
This
can
be
caused
if
the pump
is
producing
too
much
air for
your
diffusers,
or
if
the
tank
is
too
deep
for
your
pump.
The
depth
of
the
tank
should
be
as
follows:
ET4O
47”
1
.2m
ET6O
62”
1.5m
ET8O
69”
1.75m
ET100
75”
1.9m
ET12O

If
the
depth
is
higher,
please
contact
your distributor.

If
the
blower
also
has
an
output
wire
this
is
for
the connection
to
an
external
beacon
or alarm
kiosk.
