Attention:
Please
observe
the
following
rules
when
installing
the
heat
pump:
1.
Any
addition
of
chemicals
must
take
place
in
the
piping
located
downstream
from
the
heat
pump.
2.
Always
hold
the
heat
pump
upright.
If
the
unit
has
been
held
at
an
angle,
wait
at
least
24
hours
before
starting
the
heat
pump.
3.1
Heat
pump
location
The
unit
will
work
properly
in
any
desired
location
as
long
as
the
following
three
items
are
present:
1.
Fresh
air
–
2.
Electricity
–
3.
Swimming
pool
filters
The
unit
may
be
installed
in
virtually
any
outdoor
location
as
long
as
the
specified
minimum
distances
to
other
objects
are
maintained.
Please
consult
your
installer
for
installation
with
an
indoor
pool.
ATTENTION:
Never
install
the
unit
in
a
closed
room
with
a
limited
air
volume
in
which
the
air
expelled
from
the
unit
will
be
reused,
or
close
to
shrubbery
that
could
block
the
air
inlet.
Such
locations
impair
the
continuous
supply
of
fresh
air,
resulting
in
reduced
efficiency
and
possibly
preventing
sufficient
heat
output.
