FUEL
GAUGE
AND
WATER
TEMPERATURE
GAUGE
DESCRI
PTION
The
fuel
gauge
consists
of
a
tank
unit
located
in
the
fuel
tank
and
fuel
gauge
The
tank
unit
detects
fuel
level
with
its
float
converts
fuel
level
varia
tion
to
a
resistance
of
slide
resistor
installed
on
the
float
base
and
thus
controls
current
flowing
to
the
fuel
gauge
BE16
The
water
temperature
gauge
con
sists
of
a
gauge
and
thermal
transmit
ter
located
in
the
engine
block
The
thermal
transmitter
is
equipped
with
a
thermistor
element
which
converts
cooling
water
temperature
variation
to
a
resistance
and
thus
the
thermal
tr
t
c
rtrols
cUfTent
flowing
to
the
gauge
The
fuel
gauge
and
water
tempera
ture
gauge
are
provided
with
a
bi
metal
arm
and
heater
coil
When
the
ignition
switch
is
set
to
ON
current
flows
to
the
heat
coil
and
the
heat
coil
is
heated
With
this
heat
the
bi
metal
arm
is
bent
and
thus
the
pointer
connected
to
the
bi
metal
arm
is
oper
ated
The
characteristics
of
both
gauges
are
the
same
A
tolerance
may
occur
on
the
water
temperature
gauge
or
fuel
gauge
due
to
source
voltage
fluctuation
The
voltage
regulator
is
used
to
supply
a
constant
voltage
so
that
the
water
temperature
gauge
and
fuel
gauge
operate
correctly
The
operating
part
of
the
regulator
consists
of
a
bi
metal
arm
and
a
heater
coil
When
the
ignition
switch
is
turned
on
the
bi
metal
arm
is
heated
and
bent
by
the
coil
opening
the
contact
Consequently
current
to
the
coil
is
interrupted
As
the
bi
metal
cools
the
contact
closes
The
repeti
tion
of
this
operation
produces
a
pulsating
voltage
of
8
volts
which
is
applied
to
the
water
temperature
and
fuel
gauges
If
both
the
water
temperature
gauge
and
fuel
gauge
become
faulty
at
the
same
time
this
may
be
attributed
to
problem
in
the
voltage
regulator

The
refrigerant
used
in
the
air
conditioner
is
generally
called
Re
frigerant
12
R
12
No
other
refrig
erant
than
the
above
refrigerant
should
be
used
This
refrigerant
is
usually
available
in
a
small
can
or
a
cylinder
In
either
case
it
is
liquefied
under
high
pressure
in
the
container
Refrigerant
evaporates
easily
has
a
low
evaporation
point
and
moreover
since
the
latent
heat
of
the
refrigerant
is
large
it
can
abSorb
a
large
amount
of
heat
wh
err
e
vaporating
Extreme
care
must
be
exercised
when
handling
the
refrigerant
COMPRESSOR
OIL
The
SUNISO
5GS
or
SUNISO
351
should
be
used
as
refrigeration
lubricant
Mixing
of
the
two
is
allowable
The
refrigeration
lubricant
should
be
used
to
assure
the
successful
com
pressor
operation
Use
of
oils
other
than
recommended
or
mixing
of
the
oil
with
other
oils
would
cause
chemical
reaction
or
lead
to
lowered
viscosity
or
deficient
lubrication
The
oil
absorbs
moisture
as
it
con
tacts
the
air
This
points
out
the
need
for
care
not
to
expose
it
to
atmos
phere
for
an
extended

of

MAINTENANCE

MAINTENANCE
AND
SEASON
IN
INSPECTION
Both
periodic
maintenance
and
season
in
inspection
are
most
essential
to
enable
the
air
conditioner
to
give
full
performance
Perform
the
following
checks
Start
engine
and
check
refrigerant
level
through
sight
glass
on
receiver
dryer
For
details
refer
to
relative
topics
under
Refrigerant
Level
Check
2
Check
the
entire
sysiein
for
sign
of
refrigerant
leaks
Refer
to
relative
topics
under
Checking
for
Leaks
and
Refrigerant
Leaks
If
any
trace
of
oil
is
noted
at
and
around
connection
fittings
it
is
a
sure
indication
that
refrigerant
is
leaking
This
condition
can
be
corrected
easily
by
retightening
the
joints
If
any
joint
on
line
is
suspected
of
small
amount
of
leakage
use
a
leak
detector
to
locate
leaking
points

ENERAL
SERVICE
INSTRUCTION
The
servicing
of
the
air
conditioner
should
be
carried
out
only
by
well
trained
servicemen
This
chapter
de
scribes
essential
points
of
servicing
Jf
a
Jarge
amount
of
dirt
and
sand
enter
the
system
they
will
be
carried
with
refrigerant
and
may
clog
the
system
or
scratch
rotating
parts
This
points
out
the
need
for
care
in
servicing
the
system
That
is
disconnecting
joints
should
be
carried
out
in
a
dean
place
Water
should
not
be
allowed
to
get
inside
the
system
The
refrigerant
does
not
readily
mix
with
water
However
the
presence
of
even
a
minute
amount
of
water
will
cause
a
chemical
reaction
at
high
tem
perature
which
will
in
turn
produce
hydrochloric
acid
HCl
Since
hydrochloric
acid
is
highly
corro
sive
to
metals
the
aluminum
and
copper
piping
etc
will
become
corroded
and
the
refrigeration
system
will
become
clogged
