WARNING:
Ensure all electrical
power to the unit is
off
prior
to
installing
or servicing
the
equipment.
Failure to do so may cause
personal
injury
or death.
3. SITE PREPARATION
Unpacking
Equipment
--
Remove
the card-
board carton and User's Manual from the equip-
ment.
Take
care
not to damage
the
tubing
connections
when removing
the carton.
Inspect
for
Damage--
Inspect the equipment
for damage
prior to installing
the equipment
at
the job site.
Ensure coil fins are straight and, if
necessary,
comb
fins to remove
flattened
and
bent fins.
Preferred
Location
of
the Outdoor
Unit at the
Job Site
--
Conduct
a survey
of the job site to
determine
the optimum
location
for
mounting
the outdoor unit. Overhead
obstructions,
poorly
ventilated
areas, and areas subject to accumu-
lation of debris should be avoided.
The outdoor
unit must
be installed
in such
a manner
that
airflow
through
the coil is not obstructed
and
that the unit can be serviced.
Facility Prerequisites--
Electrical
power must
be supplied
to the equipment.
Electrical
power
supplied
must be adequate for proper operation
of the equipment.
The
system
must
be wired
and
provided
with
circuit
protection
in accor-
dance
with
local
building
codes
and the
Na-
tional
Electrical
Code.
Minimum
Circuit
Ampacity--
Electrical
wir-
ing to the equipment
must
be compatible
and
in compliance
with the minimum circuit ampacity
listed
on the outdoor
unit data label.
Maximum
Fuse/Circuit
Breaker Size--
Circuit
protection
for the outdoor
unit must be compat-
ible with the maximum
fuse/circuit
breaker size
listed on the outdoor
unit data label.
4. INSTALLING
THE OUTDOOR UNIT
Slab
Mount
--
The
site
selected
for
a slab
mount
installation
requires
a stable foundation
and one not subject to erosion.
The slab should
be level
and
anchored
(if necessary)
prior to
placing
the equipment
on the slab.
Cantilever
Mount
--
The
cantilever
mount
should be designed
with adequate
safety factor
to support
the weight
of the equipment,
and for
loads subjected
to the mount during operation.
Installed
equipment
should
be adequately
se-
cured to the cantilever
mount and levelled prior
to operation
of the equipment.
Roof
Mount
--The
method of mounting
should
be designed
so as not to overload
roof struc-
tures
nor
transmit
noise to the interior
of the
structure.
Refrigerant
and electrical
line should
be routed through suitably
waterproofed
open-
ings to prevent water leaking
into the structure.
5. INSTALLING
THE
INDOOR
UNIT
The
indoor
section
should
be installed
before
proceeding
with
routing
of
refrigerant
piping.
Consult
the installation
instructions
of the in-
door
unit
(i.e.:
air
handler,
furnace,
etc.)
for
details
regarding
installation.
6. CONNECTING
REFRIGERANT
TUBING
BETWEEN
THE
INDOOR
AND
OUTDOOR
UNIT
General
--
Once outdoor and indoor unit place-
ment
has been
determined,
route
refrigerant
tubing
between
the equipment
in accordance
with
sound
installation
practices.
Refrigerant
tubing should
be routed in a manner
that mini-
mizes
the length
of tubing
and the number
of
bends
in the tubing.
Refrigerant
tubing should
be supported
in a manner that the tubing will not
vibrate or abrade during system
operation.
Tub-
ing should be kept clean of foreign debris during
installation
and installation
of a liquid line filter
drier is recommended
if cleanlinessor
adequacy
of system
evacuation
is unknown
or compro-
mised.
Every
effort should
be made
by the
installer
to ensure that the field installed
refrig-
erant
containing
components
of
the
system
have
been installed
in accordance
with these
instructions
and sound installation
practices
so
as to insure
reliable
system
operation
and lon-
gevity.
The
maximum
recommended
intercon-
necting
refrigerant
line length is 75 feet, and the
vertical
elevation
difference
between the indoor
and
outdoor
sections
should
not
exceed
20
feet.
Filter
Dryer
Installation
--
A filter
dryer
is
provided
with
PS series
models
only and must
be installed
inthe liquid line of the system.
