CONTENTS
OF
KIT
The
compressor
starting
kit
consists
of
a
potential
(starting)
relay,
screws,
capacitor
strap
and
starting
capacitor
with
wiring
leads.
Kit
may
contain
more
hard-
ware
than
necessary
for
some
models
and wires
may
be
longer
than
required.

mod-
els
are
listed

IMPORTANT
-
Do
not
mis-match
kits
or
damage
will
occur
to
the
equipment.
APPLICATION
The
compressor
in
the
outdoor
unit
has
a
PSC
(perma-
nent
split
capacitor)
motor
which
does
not
require
a
starting
relay
and
capacitor,
under
ordinary
operating
conditions.
The
omission
of
these
components
elimi-
nates
a
potential
source
of
field
problems
making
the
system
more
trouble-free.
In
order
to
take
advantage
of
these
benefits
and
trou-
ble-free
operation,
the
starting
torque,
or
load,
must
be
kept
to
a
minimum.
The
suction
and
discharge
pres-
sures
must
be
nearly
equal
before
the
compressor
will
start.
Because
of
the
lower
starting
torque
inherent
in
PSC
motors,
certain
conditions
such
as
low
voltage
and
exceptionally
high
operating
temperature,
short
ther-
mostat
cycles,
etc.
can
affect
the
starting
operation.
When
such
conditions
exist,
and
cannot
be
corrected,
it
is
recommended
that
the
field
installed
compressor
starting
kit
be
used
to
convert
the
compressor
motor
to
CSR
(capacitor,
capacitor
run)
operation.
NOTE:
All
Start
Kits
listed
in
these
instructions
are
for
use
with
outdoor
units
rated
at
208-230V/
1PH/
60HZ.
AWARNING
SHOCK
HAZARD
-
Shut
off
electrical
supply
to
outdoor
unit
at
main
disconnect.
One
side
of
the
contactor
remains
closed
at
all
times,
so
main
disconnect
must
be
opened
when
servic-
ing
electrical
components
to
prevent
electrical
shock,
which
could
result
in
personal
injury
or
death.
