III. Short
Cycling
When
an air conditioner
is in operation,
its compressor
circulates
refrigerant
under
high
pressure.
Once
off,
it will
take two
to three
minutes
for
this
high
pressure to equalize.
The
air conditioning
compressor
is unable to
start against
high
pressure. Theiefore,
once
the air
conditioner
is turned off,
it
is
important
to
leave
it off
for two
to three
minutes before
restarting.
Short cyciing
the compressor
(or
starting
it before
pressures
have
equalized),
will
in some
instances,
kick
the circuit
breaker or overload.
IV.
For
Heating
("Elect-A-Heat"
Ceiling
Assembly
Model Only)
Refer
to
Figure
I'
page
3).
The optional
Elect-A-Fleat
heating assembly
is intended
to
take
the chill
out
of the
indoor
air
when the air
is a few
degrees
too
cooi
for comfort.
The heating
assembly
is an
effective "chill
chaser".
trt is
not a substitute
for a
furnace.
Do
not expect
the
heating
coil on
your
heater to
glow.
Because
the
fan draws
in
cold air
and
f,orces it over
the
coil,
the coil
will
not
turn
red.
A hint of
red may
occur
where
the
moving
air does
not
directly
touch
the
coil.
A.
Turn
the selector
srvitch
to the "LOW
HEAT"
position.
At
"LOW
HEAT",
the fan operates
on
low
speed
with
heat output
at
maximum.
B.
Rotate
the
thermostat
(temperafure
control)
su'itch
to the
position that
is the
most comfortable
to
you.
The thermostat
will
turn the
heater
on
when the
temperature
of the air
entering
the
air conditioning
unit drops
below
this setting
a
few degrees
and
automatically
turns off
when
the temperature
of
the
air entering
the air conditioner
rises a few
degrees
above this
setting.
The heater
wiil continue
to cycle
on and off
in this
fashion until
the selector
switch
is
tumed to another
mode of
operation.
C. Position the
louvers
to the
desired
direction
the
discharge
air
is to
flow.
Discharge air
temperature
can be
controiled
to
some
extent by
opening
or
closing
the louvers.
When the
louvers
are closed,
the
warmest
localized
discharge
air
is achieved.
Fully
opened
louvers
rvil1
throw the
warm discharge
air
to the
back
and
front of
the
vehicle
for more
efficient
circulation
and faster
warn-up.
Although
the
air
temperarure
is
lorl'er rvith
the louvers
fully opened,
the
heating
capacitf
is still
the same.

MAINTENANCE
I.
Owner
One
of
the biggest
advantages
to
your
new
Coleman-Mach
air
conditioner
is that
the
maintenance
needed
to keep
the
unit
in
good
care
is minimal.
In
fact about
the
only
thing
you.
the
owner,
must
take
care
of
is the cleaning
and
replacement
of
the
filters.
Filters are
made
from
long
life non-atrlergenic
natural
fibers
which
can
be cleaned
and
reused,
and
which completely
filter
the
circulated
air
when
the air
conditioner
is in operation'
If
the
filters
are
not cleaned
at
regular
intervals,
they
may
become
partially clogged
with
lint. dirt,
grease, etc.
A
clogged
filter
will
produce a
loss of air
volume
and
may
eventually
cause
an
icing-up
ofthe
cooling
(evaporator)
coil.
IMPORTA.\T
Do not operate
your
air
conditioner
for ertended
periods
of
time without
the
filter
installed.
An even more serious
condition
occurs
rvhen the air
conditioner
is operated
without
a
filter.
When this
happens
the lint,
grease, etc. that
are
normalll-stopped
b1'
the
filter are
now accumulating
in the
cooling
coil.
This
not only
leads to a
loss of
air
volume and
a
possible icing-
up ofthe
cooling
coil, but
could
also
result
in serious
damage
to the operating
components
of
the air
conditioner.
We
retommend
that the
filters
be cleaned
and
changed
at
least every two
weeks
when the
air
conditioner
is in
operation.
