INSTALLATION
In preparin
the DE-704D for installation, the followin
areas
should be considered:
1.
Ade
uate ventilation.
2.
Sizin
of suppl
wire and fuse protection.
3.
Direct wirin
from batter
to avoid electrical interference
with other e
uipment.
4.
Provisions to prevent batter
run-down.
5.
Provide correct volta
e and fre
uenc
for AC operation.
6.
Proper
roundin
to prevent electrol
sis for marine applica-
tions.
These instructions provide a
uide to insure compliance to the
situations listed above.
The Norcold dual volta
e refri
erator is desi
ned for the recrea-
tional vehicle, Marine industr
, as well as under the counter instal-
lations. A t
pical R.V. installation, for instance, re
uires the refri
-
erator to operate on 12 volt DC while in transit and 120 volt AC
while parked. The Norcold refri
erator automaticall
converts from
one power source to the other.
Unlike the absorption-t
pe refri
erator, which re
uires a constant
heat source for efficient operation,
our dual volta
e refri
erator
operates on the same principle as the standard domestic refri
era-
tor. That is, it has an electricall
operated compressor and uses
freon as its refri
eratin
medium.
Unit Location
Be sure the refri
erator is not installed in direct sunli
ht, or near
a
as stove, heater or other heat
eneratin
sources. A flan
ed
mountin
frame is provided around the front of the refri
erator
cabinet to allow build-in installation.
The refri
erator must be located and secured on a solid surface
within the vehicle.
The openin
cut-out dimensions for the refri
erator are listed in
Table 1. Measure for the openin
and determine if
ou have the
proper clearances for installation. There is no need for allowin
an
area around the cabinet for additional insulation as the Norcold
refri
erator is well insulated and re
uires no additional insulation.
Table 1
Before installin
the cabinet into the openin
, check to see if the
AC power suppl
cord of the unit is properl
connected to the AC
wall outlet and if the DC suppl
should be connected. In man
cases, the DC suppl
can be connected from outside the vehicle
b
means of the vent or access door.
Place the refri
erator into the wall openin
and secure it in place
b
fastenin
the mountin
flan
e to the wall throu
h the holes
provided.
Please note the perforated access panel at the front base of the
refri
erator. This panel allows air movement to flow under the
cabinet and over the power suppl
for coolin
.
The rear side of the unit must not be closed off without providin
ventilation. At least 50 s
. inches must be provided to allow re-
ected heat to escape.
For travel trailers, a small louver-t
pe vent of approximatel
4" x
16" area ma
be installed at the top and at the bottom of the
exterior wall of the vehicle for outside ventin
purposes.
A combination of a roof
ack and lower vent or two side vents
offers ade
uate ventin
for hi
h outside ambient temperatures.
The more air circulatin
over the condenser
located at rear
, the
more efficient the refri
erator will operate. Failure to provide the
necessar
ventilation will result in poor refri
eration. If operation at
low outside ambient temperatures is necessar
below 23° F
all
exterior ventin
must be covered to prevent serious performance
loss.
When installation incorporates exterior ventin
and operation at
low outside ambient temperatures is necessar
below 23° F
, ex-
terior ventin
must be covered or reduced coolin
efficienc
in
cabinet will result.
Power Supply
Provisions are made for connection of either 12 volts DC or 120
volts AC to the refri
erator. If both 12 volts DC and 120 volts AC
are simultaneousl
supplied, a special rela
in the refri
erator
power suppl
allows the unit to run on 120 volts AC. To convert to
DC power, the AC suppl
is simpl
disconnected.
DC Power Connection
The DC suppl
connection is located behind the perforated ac-
cess panel at the bottom front of the unit. Remove the screw from
the top center of the access panel and remove the panel. The DC
terminal box is located in the control power suppl
assembl
. The
positive and ne
ative DC suppl
connections are located in this
terminal box. The terminal box is provided with knock-out holes for
routin
the DC lead wires throu
h the side of the terminal box.
The size of the wire from
our 12 volt DC batter
is dependent
upon the distance between the refri
erator and the batter
. Refer
to Table 2 for wire size.
Table 2
This recommended wire size is to prevent a volta
e drop at the
refri
erator which is critical to DC performance.
Use of wire sizes smaller than those listed ma
cause excessive
DC runnin
time, shorter batter
life, and poor performance due to
line loss.
It is important that the 12 volt, DC suppl
wires be connected
directl
to the batter
and that the wires are dedicated to the re-
fri
erator
other appliances are connected b
separate wires
. This
practice minimizes the possibilit
of radio and T.V. interference.
Twistin
the positive and ne
ative suppl
wires further helps to
nullif
the induction effects which could further add to radio/T.V.
interference.
To the leads located in the terminal box, connect the positive
batter
lead to the red wire and the ne
ative batter
lead to the
black wire
important to be well insulated
. These splices should
be soldered or connected b
means of an approved splice con-
nector. Tape the spliced connections
enerousl
before replacin
the terminal cover box.
A 15 amp fuse should be installed as close to the batter
as
possible in the positive wire leadin
to the refri
erator. This fuse
will protect the wirin
from the batter
to the refri
erator in the
event of a short circuit.
CAUTION:
DO NOT OPERATE REFRIGERATOR ON BATTERY ALONE.
THE BATTERY MUST HAVE A CHARGING MEANS SUCH AS
AN ON-BOARD GENERATOR; IF NOT, THE BATTERY WILL
DISCHARGE IN A SHORT PERIOD OF TIME.
