Confirm
that
the
unit
filters
that
are
being
used
are
clean.
This
contributes
to
the
proper

of
the
unit
by
ensuring
that
there
is
adequate
air
flow
across
the
coil.
SAFETY
NOTE:
In
the
following
part
of
the
procedure
it
will
be
necessary
to
access
the
areas
around
the
electrical
wiring
and
the
circuit
board.
Do
not
adjust
or
remove
any
board
connections
or
wiring
connections
to
other
components
without
first
powering
down
the
unit.
On
older
SKH
008
to
018,
the
disconnect
will
be
a
power
plug
at
a
receptacle.
On
model
sizes
20
and
post
Oct

SKH
008
to
018
up
there
will
be
a
switch
disconnect.
Disconnects
are
usually
within
reach
of
the
unit.
Exercise
caution
at
all
times.

Operation
(3
‐
Phase):
With
the
power
OFF,
remove
the
front
panel
and
the
electrical
panel
cover.
Remove
any
thermostat
block
and
turn
power
ON
to
the
unit
with
the
electrical
disconnect.
Ensure
that
the
correct
standby
protocol
is
in
place
‐
the
following
board
lights
will
come
on
in
standby:
Power,
HP,
LP,
and
Alarm.
Inspect
the
fan
section
to
ensure
that
it
is
clear
of
any
debris
and
that
the
fan
rotates
freely.
CGC’s
Horizontal
Spacekeeper
units
come
equipped
with
a
3
‐
phase
fan
and
compressor
that
are
matched
to
each
other
as
well
as
the
other
internal
components.
Although
internal
connections
to
the
fan
and
compressor
are
made
at
the
factory,
variances
in
power
supply
in
the
field
will
require
that
both
components
be
tested
for
correct
operation.
The
procedure
is
outlined
below:
•
Using
a
screwdriver
with
an
insulated
handle,
push
and
hold
in
the
manual
plastic
button
of
the
fan
contactor
for
a
few
seconds,
making
sure
not
to
touch
any
of
the
metal
parts.
This
will
cause
the
fan
to
rotate.
•
The
correct
rotation
will
have
the
fan
vanes
rotating
towards
the
housing
exit.
•
If
the
rotation
is
incorrect,
power
OFF
the
unit
and
switch
two
of
the
three
wires
at
the
bottom
of
the
contactor
that
feed
the
fan.
Power
ON
the
unit
and
again
using
the
screwdriver,
press
the
contactor
for
a
few
seconds
to
activate
the
fan.
The
rotation
should
now
be
reversed.
