stress
on
the
plumbing
and
cause
leaks.
In
this
kind
of
situation,
a
pressure
regulator
should
be
installed
on
the
outlet
side
of
the
unit
and
drawdown
tank.
7.
The
Bubble
‐
Up®
Jr
Interactive™
requires
a
quadplex
outlet
wired
to
a
dedicated
20A
circuit.
Use
a
20
amp
duplex
GFCI
receptacle
for
the
yellow
float
switch
cord
for
UL
(See
Figure
8).
This
circuit
should
use
#12
AWG
wiring.
8.
Install
the
2.1
gallon
water
expansion
tank
on
the
outlet
side
of
the
unit.
See
Figure
11.
This
tank
is
included
to
prevent
the
pump
from
starting
and
stopping
quickly
(“short
cycling”)
when
there
are
short
‐
term
demands
for
small
amounts
of
water.
9.
Install
a
pre
‐
filter
on
the
inlet
side
to
protect
the
solenoid
from
sediment
clogging.
See
figure
11.
The
pre
‐
filter
should
be
a
sediment
‐
type
filter
with
a
5
micron
rating.
Do
not
use
a
carbon
‐
type
filter.
10.
Attach
the
red
handled
bypass
valve.
11.
The
bypass
valve
is
included
so
that
the
unit
can
be
taken
out
of
service
easily
without
interrupting
the
water
supply.
Plumb
the
inlet
line
and
outlet
line
so
that
the
water
can
continue
the
water
demand
if
the
bypass
valve
is
set
to
the
bypass
position.
12.
Pour
one
ounce
of
bleach
into
the
blower
attachment
nipple
to
disinfect
the
unit.
See
Figure
6
for
location
of
blower
attachment
nipple.
13.
Firmly
slip
the
blower
onto
the
blower
attachment
nipple
and
tighten
clamp
to
secure
blower
to
nipple.
Caution!
Do
not
use
PVC
pipe
cement
on
this
connection.
Note:
If
blower
inlet
is
connected
to
draw
air
from
an
outdoor
source,
make
sure
that
no
moisture
can
get
into
a
blower
motor.
If
an
outdoor
source
is
desired,
a
dryer
vent
kit
can
be
modified
by
removing
the
flap
check
and
replacing
it
with
a
screen.
Be
sure
to
install
the
kit
as
directed
and
run
the
hose
down
to
the
floor
in
the
area
of
the
Bubble
‐
Up®
Jr.

Important
note:
Do
not
plug
in
pump

cord
until
Bubble

tank
is
filled
to
normal
operating
water
depth.
16.
Run
the
vent
line
outdoors
using
2”
PVC
piping.
Try
to
make
this
line
as
short
and
direct
as
possible*.
Make
all
of
the
pipe
connections
air
tight
using
proper
PVC
pipe
cement.
Important
note
about
vent
line
piping:
Use
¼”
per
foot
pitch
towards
the
Bubble
‐
Up®
Jr
Interactive™.
*Caution!
Do
not
install
a
vent
outlet
line
which
is
longer
than
50’,
and
includes
more
than
five
elbows.
This
can
create
excessive
backpressure
and
interfere
with
the
operation
of
the
unit.
On
longer
runs,
use
larger
pipe.
Call
the
factory
for
details
on
specific
applications.
If
this
is
done
the
blower
unit
of
the
Bubble
‐
Up®
Interactive™
can
create
pressure
within
the
main
tank.
This
can
cause
water
from
the
main
tank
to
be
forced
up
through
the
overflow
pipe
and
spill
onto
the
water
sensor
terminal
block
thus
activating
the
water
alarm
valve,
shutting
down
the
unit.
This
can
also
occur
if
the
vent
outlet
line
is
plugged.
Caution!
Do
not
install
the
vent
opening
at
a
location
where
the
vent
gasses
could
be
blown
back
into
an
occupied
space.
