Service Person
Electrical -
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.
Lubrication
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.
