Your
heater
should
be
horizontally
or
vertically
sited
allowing
sufficient
space
for
pipe
connections
and
wiring,
it
should
be
securely
screwed
to
a
base
or
wall.
The
heater
should
be
installed
at
a
low
point
in
the
filtration
system.
It
must
be
positioned
downstream
of
(after)
the
filter
and
upstream
of
(before)
any
dosing
or
other
water
treatment
plant.
(see
Fig.2)
It
is
essential
that
the
plumbing
connecting
to
and
from
the
heater
has
a
minimum
size
of
1¼”.
To
assist
correct
air
purging
and
to
ensure
the
heater
remains
completely
full
of
water
during
operation,
the
return
pipe
which
carries
the
water
back
to
the
pond
must
incorporate
a
safety
loop
or
‘kick
‐
up’
in
the
pipe
as
close
as
possible
to
the
heater
(see
fig
3).
NOTE:
When
coupling
to
a
flexible
hose
a
safety
loop
can
simply
be
created
by
routing
the
hose
up
and
over
an
obstacle.
Remember
to
use
hose
clamps
to
securely
fasten
all
connections.
The
heater
must
be
installed
within
a
dry
weather
proof
enclosure.
CAUTION!
If
the
heater
is
not
used
during
winter
months
it
must
be
drained
to
prevent
frost
damage.
IMPORTANT!
All
heaters
have
been
supplied
pre
‐
wired
with
a
power
cord
and
require
a
Ground
Fault
Interruption
Circuit
(GFIC)
outlet
for
safety
protection.
