Plumb
this
expansion
tank
near
the

amount
of
water
heater
thermal
expansion.
If
you
have
a
tank

Radon
Testing
Note:
It
is
important
to
install
a
new
sample
valve
or
boiler
drain
in
new
piping
so
that
the
radon
testing
is
not
influenced
by
old
piping.

Set
the
main
tank
of
the
Bubble
‐
Up®
Jr
Interactive™
in
the
desired
location
that
can
hold
the
weight
of
the
Bubble
‐

shown
in
the
Specification
Section
on

In
case
of
a
malfunction,
the
unit
could
overflow.
The
Bubble
‐
Up®
Jr
Interactive™
is
fitted
with
an
overflow
pipe.
(The
overflow
pipe
is
mounted
near
the
rear
of
the
unit.
See
Figure
7)
Take
this
into
account
when
positioning
the
unit.
It
is
best
if
the
unit
can
be
positioned
near
a
drain
or
sump
pit
with
a
sump
pump.
5.
Depress
the
high
water
alarm
float
so
it
is
flush
with
the
rubber

Set
water

one
wire
on
the

Important
note
about
overflow:
The
Bubble
‐
Up®
Jr
Interactive™
incorporates
a
high
water
alarm
float
switch
in
the
cord
seal,
a
water
alarm
tank
top
terminal
block
sensor
and
a
water
alarm
floor
sensor.
The
control
will
operate
the
water
alarm
valve
and
shut
off
incoming
water
when
there
is
an
obstruction
in
the
radon
exhaust
pipe,
water
around
the
floor
sensor
or
tank
to
terminal
block
sensor,
a
faulty
float
switch
assembly,
tangled
float
switch
assembly,
or
if
the
solenoid
valve
is
stuck
open.
This
water
alarm
valve
has
a
battery
backup
and
will
function
during
a
power
outage.
However,
additional
overflow
precautions
should
be
taken
such
as
connecting
the
overflow
to
a
proper
drain.
Caution!
Normally,
the
output
from
the
pump
is
at
a
pressure
of
70
PSI.
This
should
not
create
a
problem
in
an
installation
where
the
existing
plumbing
is
in
good
condition.
However,
in
an
installation
where
the
existing
plumbing
cannot
withstand
the
operating
pressure
of
the
Bubble
‐
Up®
Jr
Interactive™,
the
output
from
the
pump
may
