1.1. TOOLS AND PARTS
Assemble
the
required
tools
before
starting
installation.
Read
and
follow
the
instructions
provided
with
any
tools
listed
here.
Tools
Needed:

required
by
Plumbing
or
HVAC
standards
Wrenches,
Screw
Drivers,
Hose,
Glycol
Parts
Needed:
Check
local
codes
and
HVAC
supplier.
Check
existing
electrical
supply,

1.2 SYSTEM REQUIREMENTS:
Aermec
heat
pump
system
are
derived
from
actual
laboratory
testing
of
the
equipment.
It
is
recommended
that
all
deisgn
criteria
be
met
or
exceeded
to
ensure
proper
operation
and
efficient
performance.
The
designed
system
criteria
are
listed
in

This
heat
pump
has
been

charged
with
a
quantity
of
refrigerant
(R410A)
1.3 LOCATION REQUIREMENTS
This
heat
pump
is
designed
to
be
located
outdoors
with
sufficient
clearance
for
free
entrance
to
the
inlet
and
discharge
air
openings.
The
location
must
also
allow
for
adequate
service
access.
See
“Minimum
Clearances.”
Where
possible,
select
a
location
for
the
heat
pump
which
is
shaded
from
the
direct
rays
of
the
sun
most
of
the
time.
North
or
east
locations
are
usually
most
desirable.
Position
the
heat
pump
to
avoid
direct
contact
with
water,
snow
or
ice
from
a
roof
line
overhead.
The
heat
pump
must
be
installed
on
a
solid,
level
mounting
pad
that
will
not
settle
or
shift.
Isolate
the
pad
from
the
building
structure
to
avoid
possible
transmission
of
sound
or
vibration
from
the
heat
pump
into
the
conditioned
space.
The
heat
pump
foundation
should
be
raised
to
a
minimum
of
3
in.
above
finish
grade.
In
areas
which
have
prolonged
periods
of
temperatures
below
freezing,
and/or
snowfall,
the
heat
pump
should
be
elevated
above
the
average
snow
line.
If
heat
pump
is
to
be
installed
on
a
flat
roof,
it
should
be
on
a
platform
or
other
support
which
will
raise
the
unit
base
pan
12
in.
minimum
above
the
surface
of
the
flat
roof.
Care
should
be
taken
to
ensure
free
drainage
of
condensate
from
defrost
cycles.
This
will
prevent
ice
accumulation.
The
heat
pump
should
be
located
away
from
walkways
to
prevent
possible
icing
from
defrost
condensate.
Avoid
placing
the
heat
pump
near
areas
such
as
sleeping
quarters
or
study
rooms.
Normal
operating
sound
levels
may
be
objectionable
if
the
heat
pump
is
placed
near
certain
rooms.
A
shift
in
sound
type
does
occur
during
the
defrost
mode.
The
defrost
mode
generally
lasts
no
longer
than
5
minutes

1.4 MINIMUM WATER VOLUME
IMPORTANT:
Refer
to
“Aermec
System
Water
Volume
Guide”
(you
can
download
it
on
aermec.us
in
tutorial
books
section)
ANK
heat
pumps
need
a
minimum
volume
of
35
gallons
of
water/glycol.
If
the
version
is
an
HA
it
has
an
internal
25
gallon
tank
so
the
system
must
contain
a
minimum
of
10
additional
gallons
when
all
zones
but
the
smallest
are
closed
or
not
operating.
(Only
count
the
smallest
zone
volume
along
with
the
pipes
to
the
manifold.
If
the
heat
pump
does
not
have
an
internal
buffer
tank
you
must
add
35
gallons
in
the
system
with
a
buffer
tank
or
piping.
