All electrical work
and/or inspection
should
be
performed
only by
qualified
service
personnel.
Contact
your
nearest
Airxcel, Inc.
Service Center if
electrical
problems
should arise.
Check
Points
-
Failure
to start
or to cool
the air are
sometimes
problems
with
air conditioning
units.
The Coleman-Mach RV
air conditioner
is designed
to operate on 115 volt electrical
power.
If the
compressor on the air conditioner
fails
to start, check
with
your
Airxcel, Inc.
Service Center
to determine
C.
that
the
proper
wire size is
connected to the unit, the
proper
circuit breakers
are
installed
as
protection
devices
on the electrical
circuit and the
proper
sized
extension
cord is
being used for the distance
covered
from
the utility
outlet to the RV. The required
minimum
wire size is
#12 AWG for lengths
up to
25
feet
(larger
wire
size for
greater
distances). Each
air
conditioning
unit must be
protected
with a 20
amp time
delay fuse
or circuit breaker.
If
the
air conditioner
continues to trip off the
circuit
breakers,
have
an electrician check the starting
amperage
and running
amperage on the unit. If
the
circuit breaker continues
to trip off and the
electrical
consumption
is found to be normal, it
will
require
the replacement
of the
faulty
circuit breaker.
If
all electrical
power
to the air conditioner is normal
but neither
the fan
or the compressor will
operate,
the
connector
piug
located
behind the ceiling
assembly
control
box should be checked
to
determine
whether
it is faulty.
On
the heating-cooling
air conditioner
models, if
all
electrical
power
to the unit is normal
and the fan
runs
but
you
never
get
any heated
air, then the
electrical
plug
to the heating
unit should be
checked
for
a secure
corinection. Ifthis
does not ccrrect
the
malfunction,
the heating
thermostat or limit
switch
may be faulty.
Mechanical
Integrity
-
The air condrtioner
should
be
inspected periodicaiiy
to be sure that the bolts which
secure the
unit to the roofare tight
and
in
good
shape. Also,
an examination
of the
plastic
shroud
covering
the air conciitioner
on the top of the roof
should
be made
periodically"
Be
sure the four
mounting
screws and washers
are snug and holding
the
shroud to the
air conditioner. Also examine
the
shroud
to be sure it is
not developing cracks or has
suffered
damage from impact.

DANGER
DISCONNECT
THE
POWER
SUPPLY
TO
THE TINIT
BEFORE
SERVICING TO
PREVENT A
SHOCK
HAZARD
OR POSSIBLE
INJTIRY FROM
MOVING
PARTS.
The
blower
drive motor
on some units may include
oiling
cups
at the
top of the motor.
There is no requirement
to
oil
the
journals
under normal
operating conditions.
However,
if lubrication
to the
unit
is
desired,
use only SAE
20
non-detergent
fype oil. DO NOT
OVER OIL
-
three to
four
drops in
each oil hole
onee a
year
if sufficient.
