IMPORTANT

This refri

erator is desi

ned to operate on power suppl

limits as follows:

120 volt AC operation: 132 volts max., 108 volts min. 12 volt DC operation: 15.4 volts max., 12 volts min.

61 hertz max., 59 hertz min.

Operation on power supplies exceedin

the maximum limits ma

cause dama

e and void the warrant

. Operation on power

supplies below the limits will result in unacceptable performance.

When operatin

on 12 volts DC, a batter

source must be used. Operatin

the refri

erator on a convertor or batter

char

er alone

(

without a batter

in the circuit

)

is not recommended since these devices do not normall

suppl

a filtered DC source. Unsatisfactor

operation will result.

DE-704D

INSTALLATION

In preparin

the DE-704D for installation, the followin

areas

should be considered:

Ade

uate ventilation.

Sizin

of suppl

wire and fuse protection.

Direct wirin

from batter

to avoid electrical interference

with other e

uipment.

Provisions to prevent batter

run-down.

Provide correct volta

e and fre

uenc

for AC operation.

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

as stove, heater or other heat

eneratin

sources. A flan

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

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

means of the vent or access door.

Place the refri

erator into the wall openin

and secure it in place

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

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

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.

AC Power Connection

The 120 volt AC power connection is made b

connectin

the

refri

erator’s AC cord to a standard 120 volt

rounded receptacle.

See Fi

ure 2.

The 120 volt AC suppl

wires, to which the refri

erator is con-

nected, should be routed throu

h the fuse panel or circuit breaker

that protects the vehicle when an outside power source is used.

This connection should be permanentl

wired in accord-

ance with existin

overnin

codes. The use of an extension cord

is not recommended.

CAUTION:

IF AC POWER IS SUPPLIED BY AN ON-BOARD GENERATOR,

IT IS VERY IMPORTANT TO HOLD BOTH VOLTAGE AND FRE-

QUENCY WITHIN THE TOLERANCES STATED IN THE FRONT

OF THIS MANUAL

OPERATION

Power Source

As previousl

noted, the Norcold refri

erator can be operated on

either 12 volts DC or 120 volts AC. If both power sources are

connected simultaneousl

, the refri

erator will operate on 120

volts AC. A special rela

disconnects the DC power. To operate

on DC power, the AC source must be disconnected, allowin

the

rela

to switch to 12 volts DC.

On DC operation the circuit is protected electronicall

for over-

current and overvolta

e. Likewise on AC operation the circuit is

protected from overload conditions b

a bi-metallic current limitin

device.

Temperature Control

A sin

le thermostat controls the operation of the refri

erator on

AC or DC. It is located on the panel below the front door

(

See Fi

)

. The dial is marked "1" throu

h "5". The nearer the dial is set to

"5", the colder the temperature becomes in the cabinet.

There is no need to read

ust the settin

of the thermostat for

dual operation. Once the desired temperature is reached, the

thermostat will control the cabinet temperature e

uall

well on

either volta

e suppl

Initial Start-up

Before operatin

the refri

erator for the first time, check to see

that the AC and DC suppl

connections are correct. If normal, the

reen power indicator will be illuminated. Connect the vehicle to

the external power suppl

of 120 volts. Turn the switch located

next to the thermostat to the "ON" position. Turn the thermostat

dial to the number "3" settin

. The unit should be operatin

. You

can hear the compressor sound b

placin

our ear next to the

refri

erator.

Allow approximatel

five minutes of operation and open the

freezer compartment door. Place

our hand at the upper left rear

corner of the coolin

plate. This is the area of the plate that will

in coolin

first. If

ou notice a coolin

effect at this point, then

the unit is functionin

properl

Close the refri

erator door and allow the refri

erator to operate

on AC until it c

cles or shuts itself off. This indicates the thermo-

stat is operatin

and that the refri

erator is coolin

on AC opera-

tion.

Now, disconnect the AC suppl

and open the refri

erator door so

that the cabinet interior will warm up and allow the thermostat to

demand coolin

As soon as the unit’s compressor be

ins to operate, close the

refri

erator door, allowin

the unit to run. It should shut off or c

cle

within 10 to 20 minutes indicatin

the DC operation is correct.

Special Requirements For

Marine Installations:

The DE-704D is internall

wired so that the AC and DC

circuits are isolated from each other. If the positive

(

+12 volts

)

DC input is

rounded in an

(

cuts in the wire insulation,

improperl

insulated connections, etc.

)

, a volta

e potential

could be developed throu

hout the boat in which corrosion

develops on an

metal parts exposed to water.

This situation ma

be avoided b

wirin

the boat so that AC

and DC

rounds are common and wirin

is protected per

NNMA CERTIFICATION HANDBOOK

(

1987

)

. Inspect all wir-

to insure that insulation has not been dama

ed. Plastic

wire clamps are recommended.

MAINTENANCE OF YOUR REFRIGERATOR

Cleaning Cabinet and Door

Wipe with a soft, dr

cloth. To remove dirt, use a cloth mois-

tened b

a warm neutral deter

ent solution. Never use hot water.

After cleanin

, wipe with a dr

cloth.

CAUTION:

Never use a brush, powder soap, cleanser, acid, benzene,

asoline, or thinner. These tend to leave scratches on the coat-

Gasket (door cushion)

Wipe awa

dirt with a soft cloth moistened b

a neutral deter-

ent. Do not soak the cloth excessivel

. If water

ets inside, the

insulatin

effect ma

become temporaril

impaired.

Attachments

Wash all attachments in soap suds. Rinse and wipe clean with a

cloth.

To Turn Off The Refrigerator

ou will not be usin

the refri

erator for a da

or two, turn the

thermostat knob to "1". For a lon

er period, set the On-Off switch

to "OFF" and disconnect power b

removin

the AC plu

from it’s

socket. Also, disconnect the DC power from it’s source.

When not in use, the refri

erator should be emptied, cleaned,

and dried, and the door left a

ar.

Defrosting

Set the On-Off switch to "OFF". When frost is melted, wipe the

compartment plates with a soft, dr

cloth. A better su

estion is to

set the dial to "1" before

ou retire for the ni

ht. The frost will be

one the next mornin

Do not use sharp ob

ects to chip ice from the coolin

plates.

Information on battery power

The batter

power re

uired for the operation of the refri

erator is

dependent upon the number of DC appliances bein

used, the

pe of operation desired and c

clin

pattern desired.

A batter

must also be sufficientl

char

ed to prevent overdraw.

A batter

is rated usuall

in ampere-hours; that is, it is capable

of sustainin

it’s rated ampere capacit

for a period of one hour.

If the total ampera

e load of the vehicle is hi

(

25 amperes

)

then the installation of a 72 ampere-hour batter

will not provide

the re

uired power for an

len

th of time unless it is aided b

rechar

source such as an alternator or

enerator.

Various load re

uirements of the vehicle’s DC s

stem dictate the

ampere-hour capacit

that should be installed.

Refer to Fi

ure 3 for the su

ested dual-batter

wirin

dia

ram.

You will note that in this dia

ram there are 2 separate batter

sources. One source is the vehicle or car batter

used exclusivel

for the operation of the en

ine and accessor

uipment such as

head li

hts. The other source is for the operation of the DC appli-

ances within the recreational vehicle or boat. This batter

source

is referred to as the accessor

or house batter

and is used solel

for that purpose.

Both of these batter

sources are char

ed b

one alternator or

enerator which is powered b

the vehicle en

ine. This char

device should be of ade

uate ampera

e ratin

so that a short

ine run will brin

the batteries up to full char

e. The standard

alternator has a minimum ratin

of 60 amperes.

Check

our volta

e re

ulator or cut-out for correct char

level.

Volta

e should be 13.5 to 14.5. volts to the batter

ure 3

Important Points Regarding Battery-Powered

Sources

The dual batter

switch or batter

isolator is an important compo-

nent as it permits the alternator or

enerator to char

e both the

accessor

batter

and the vehicle batter

durin

operation of the

vehicle en

ine. However, it limits the current draw of the DC appli-

ances to the accessor

batter

source when the en

ine or vehicle

is idle or stopped. Thus it assures that the vehicle batter

is full

char

ed for startin

the en

ine. The batteries referred to in Fi

ure

3 are two 6 volt

olf cart batteries connected in series to provide

12 volts. Golf cart batteries are su

ested for the followin

rea-

sons:

1. Lar

er plate construction.

2. Deep draw characteristics.

3. Hi

h ampere-hour ratin

The standard

olf cart batter

has a ratin

of approximatel

185-

205 ampere-hours. When two of these batteries are connected in

series, the result is 12 volt DC at 185 or 205 ampere-hour capac-

The DC suppl

to the refri

erator is connected to the ne

ative

post of one batter

and to the positive post of the other batter

The power converter or solid state batter

char

er shown in Fi

ure 3 is an essential item for batter

-operated s

stems.

The converter is operated on 120 volt AC and should have an

output ratin

of 12.6-l4.5 volts DC at approximatel

20-50 ampere

capacit

. Durin

120 volt operation, the converter is used to

char

e the batteries and to operate the DC appliances. It has the

capacit

to operate items such as li

htin

, water pumps, exhaust

fans, and sanitar

facilities while maintainin

or char

the bat-

teries. Char

rate varies from 5-20 amperes per hour.

The Norcold dual volta

e refri

erator automaticall

switches from

AC to DC or from DC to AC. When a power suppl

of 120 volts

AC is connected to the vehicle, the volta

e selection rela

is ener-

ized and disconnects the unit from DC operation. This uni

feature assures 120 volt operation when available and permits the

power converter to concentrate it’s char

facilities to the batter-

ies or to other DC appliances.

When the AC suppl

is disconnected, the refri

erator automat-

icall

reverts to DC operation. Settin

the On-Off switch to the

"OFF" position will prevent operation on AC or DC.

The followin

are su

estions for efficient operation of the refri

erator:

1. The thermostat dial is numbered from 1 throu

h 5, with the

number 5 settin

the maximum coldest position. In order to

conserve batter

power, it is advisable to set the thermostat

dial at the lowest settin

that will provide ade

uate refri

era-

tion. This practice will reduce the runnin

time of the refri

erator and draw less current from the batter

. A settin

of 2

or 3 is a normal position.

2. Alwa

s operate the refri

erator on 120 volts AC when avail-

able, especiall

durin

initial start-up or pull-down c

cle of

the refri

erator. Dependin

upon the ambient temperature,

the initial start-up ma

uire 1-2 hours of continuous op-

eration before refri

erator temperature are attained and unit

clin

ins.

3. Never emplo

uick-char

ers" to the batter

unless the On-

Off switch is set to the "OFF" position or the 12-volt DC

leads to the refri

erator are disconnected. Possible inverter

dama

e will occur if the hi

h volta

e of "

uick char

ers" is

permitted to ener

ize the DC circuits of the inverter.

4. The use of a commercial 12-volt DC to 120-volt DC solid

state inverter, converter,

asoline or belt-driven

enerator

with 120 volt AC output is not recommended for operatin

the refri

erator unless the manufacture of the foremen-

tioned devices

uarantee the output volta

e to be 120 volts

AC plus or minus 10 percent and the fre

uenc

to be 60

hertz plus or minus one hertz. Devices that cannot meet

the specified tolerances do not hold the re

uired fre

uenc

provide poor performance of the refri

erator, and dama

the resonance sprin

s in the compressor.

5. When connectin

the refri

erator to the DC suppl

, observe

the correct polarit

. If the polarit

is reversed

(

positive con-

nected to ne

ative terminal

)

, the circuit protection will shut

the unit down. The wire leads must be disconnected and re-

connected properl

, and circuit breaker reset.

Installation Of Decorator Panel

cuttin

to size as per illustration. Use di-

mensions shown in Fi

ure 4. The maximum panel thickness must

not exceed 3/16"

(

4.76mm
