VENTILATION REQUIREMENTS
GENERAL INFORMATION
Ventilation is one of the requirements for proper cooling
unit operation. The installation should be made in such a man-
ner as to separate the combustion system from the living space
of the mobile home or recreational vehicle. Openings for air
supply or for venting of combustion products should have a
minimum dimension of not less than 1/4 inch.
Proper installation requires one lower fresh air intake and one
upper exhaust vent. Certified installations require one roof vent
and one lower side vent or one upper side vent and one lower
side vent. The ventilation kits shown in this manual have been
certified for use with DMR/DMC 7-series. The table below
displays the components and their part no.
Components Part no.

3311236.XXX*
3109350.XXX*
* Replace “XXX” with the color code numbers. For color codes,
contact your supplier. For further information, contact your dealer or
distributor.
The ventilation kits must be installed and used without modi-
fication! An opening toward the outside at floor level in the
refrigerator compartment has to be provided for ventilation of
heavier-than-air fuel gases. The lower vent of the recommended
kits is provided with proper size openings. The flow of combus-
tion and ventilating air must not be obstructed.
The lower side vent is fitted with a panel, which provides an ad-
equate access opening for ready serviceability of the burner and
control manifold of the refrigerator. This should be centered on
the back of the refrigerator.
CAUTION
It is of especially importance that the airflow
around the burner housing, the boiler insulation
and the ow of combustion gases must not be
obstructed. Items placed in the vicinity of the
refrigerator compartment accordingly must be
secured away from the refrigerator tubing and
flue.
VENTILATION HEIGHTS
It is essential that all maximum or minimum dimensions are strict-
ly maintained, as the performance of the refrigerator is dependent
on adequate flow of air over the rear of the refrigerator.

INSTALLATION PROCEDURE
b) Secure the refrigerator and the lower front strip
with two screws.
2. Two screws installed in the top frame.
3. One screw installed at the back in the rear base.
GENERAL INSTRUCTIONS
•Make sure the floor is solid and level.
•Do not install the appliance directly on carpeting. Carpet-
ing must be removed or protected by a metal or wood panel
beneath the appliance, which extends at least full width and
depth of the appliance.
•The refrigerator must be level and installed in a substantial
enclosure.
INSTALLING AND SECURING THE
REFRIGERATOR
When installing the refrigerator in the enclosure, all areas with-
in the recess have to be sealed. Verify that there is a complete
seal between the front frame of the refrigerator and the top,
sides and bottom of the enclosure. A length of sealing strip is
applied to the rear surface of the front frame for this purpose.
The sealing strip should provide a complete isolation of the
appliance’s combustion system from the vehicle interior.
Be careful not to damage the
sealing strip when the
refrigerator is put in place!
Wood strip
A wood strip must be in place across the upper
opening of the enclosure. The top frame of the
refrigerator will be anchored to the wood strip
with screws.
After the refrigerator has been installed (ensuring a combustion
seal at the front frame), the refrigerator must be secured in the
enclosure with five screws (not included). Furthermore, a lower
front strip (shipped as a loose part) should be attached.
NOTE! It is important to follow the sequence in securing
the refrigerator since failure in doing that can cause leakage
between the frame and cabinet!
Install the five screws in the following order:
1. Two screws installed through the front base and
installation of the lower front strip.
a) Install the lower front strip by sliding it under the
bottom hinge plate. The hinge plate can be on the
right or left side depending on the door swing.
Once the lower front strip is slipped under the
hinge, the part is possible to swing into place.

CONNECTIONS
GAS CONNECTION
Hook up to the gas supply line is accomplished at the manual
gas valve, which is furnished with a 3/8” SAE (UNF 5/8” -18)
male flare connection. All completed connections should be ex-
amined for leaks using a solution of liquid detergent and water.
The gas supply system must incorporate a pressure regulator
to maintain a supply pressure of not more than 11 inches water
column. When testing the gas supply system at test pressures:
• > 1/2 psi - the refrigerator and its individual shutoff valve
must be disconnected from the gas supply piping system.
•≤1/2 psi - the appliance must be isolated from the gas
supply piping system by closing its individual manual
shutoff valve.
If detailed instructions on the installation and connection to
the gas supply are required, please contact your dealer or
distributor.
TESTING LP GAS SAFETY SHUT OFF
The gas safety shut off must be tested after the refrigerator is
connected to LP gas supply.
To test the gas safety shut off, follow these steps:
1. Start the refrigerator and switch to GAS mode.
2. Check that the gas flame is lit and the GAS mode
indicator lamp is on.
3. Close the manual gas shutoff valve at the back of the
refrigerator, see “APPENDIX A - REARVIEW
EQUIPMENT”
4. Wait for approx. 45 seconds. The ignition attempt is
interrupted LP is displayed (flashing).
5. Remove the protection cover.
6. Open the manual gas shutoff valve. Do not change
any button positions on the control panel.
7. Apply a non-corrosive commercial bubble solution
to the burner jet orifice. No bubbles should appear at
the opening of the burner jet orifice. The presence of
bubbles indicates a defective gas safety shutoff, and
service is required.
8. If no bubbles were present at the burner jet orifice, it
should be rinsed with fresh water. Be careful not to
damage the burner jet orifice.
9. Put back the cover.
10. Press the ON/OFF button off and then back on. Nor-
mal operation of the burner should return.
11. Allow the burner to operate for a minimum of five
minutes.
ELECTRICAL CONNECTION
120V AC CONNECTION
The refrigerator is equipped with a grounded three-prong plug
for protection against shock hazards. It should be plugged
directly into a properly grounded three-prong receptacle. Do not
cut or remove the grounding prong from this plug!
The free length of the cord is 2 feet and therefore recommended
that the receptacle be located to the left side (opposite side of
refrigerator burner assembly) of the refrigerator (viewed from
the rear).
To allow easy access through the vent door,
place the receptacle 3” above the refrigera-
tor mounting floor. The cord should
be routed to avoid direct contact with the
burner cover, flue cover or any other compo-
nents that could damage the cord insulation.

WARNING
EXPLOSION HAZARD. Never use an open ame
to check for gas leaks. Failure to heed this warn-
ing could cause an explosion resulting in death or
severe personal injury.
6
!
12V DC CONNECTION
The refrigerator requires a continuous 12V DC supply to main-
tain the automatic energy system. The connection is made to
the positive (+) and negative (-) terminals of the terminal block
on back of the refrigerator, see “APPENDIX A - REARVIEW
EQUIPMENT”.
Correct polarity must be observed when connecting to the DC
supply. Do not use the chassis or vehicle frame as one of the
conductors. Connect two wires at the refrigerator and route to
the DC supply. The connections must be clean, tight and free
from corrosion.
Ensure that the wires from the battery to the refrigerator are
able to handle the load. The distance the current must travel
from the battery to the refrigerator dictates the AWG wire size
to be used. Inadequate wire sizes can result in a voltage drop
which affects the refrigerator performance.
Recommended wire sizes are displayed in the following table:

If the refrigerator is operated when it is not level and the
vehicle is not moving, liquid ammonia will accumulate in sec-
tions of the evaporator tubing. This will slow the circulation
of hydrogen and ammonia gas, or in severe cases, completely
block it, resulting in a loss of cooling.
When the vehicle is moving, the leveling is not critical, as the
rolling and pitching movement of the vehicle will pass to either
side of level, keeping the liquid ammonia from accumulating in
the evaporator tubing.
Sodium chromate is used to prevent corrosion (less than
2 weight % of the coolant).
WHEN THE REFRIGERATOR IS NOT IN USE
Any absorption refrigerator that is to be taken out of service for
an extended period of time should be turned off.
AUTOMATIC ENERGY SELECTOR
CONTROL SYSTEM
The refrigerator is equipped with an automatic energy selector
control system. The user turns the refrigerator on, selects
the desired temperature and then, the refrigerator automatically
selects the most suitable energy source available (either
120V AC or LP gas operation). The system can be set by the
user to be fully automatic (AUTO mode is selected) or to oper-
ate on LP gas only (AUTO mode is off).
The refrigerator controls will work down to 9.6 volt DC.
AUTO MODE / GAS MODE
The refrigerator is equipped with a control system where the
user can choose to turn the AUTO mode on or off.
AUTO MODE IS TURNED ON
The system is fully automatic which means that it selects the
most suitable energy source available, either 120V AC or LP
gas operation.

REFRIGERATOR OVERVIEW
ABSORPTION COOLING SYSTEM
In an absorption refrigerator system, ammonia is liquefied in
the finned condenser coil at the top rear of the refrigerator.
The liquid ammonia then flows into the evaporator (inside the
freezer section) and is exposed to a circulating flow of hydro-
gen gas, which causes the ammonia to evaporate, creating a
cold condition in the freezer.
When starting this refrigerator for the very first time, the cool-
ing cycle may require up to four hours of running time before
the cooling unit is fully operational. The tubing in the evapora-
tor section is specifically sloped to provide a continuous move-
ment of liquid ammonia, flowing downward by gravity through
this section.
LEVELING THE REFRIGERATOR
Leveling is one of the requirements for proper operation with
absorption refrigerators. To ensure proper leveling the vehicle
needs to be leveled so it is comfortable to live in (no noticeable
sloping of floor or walls).
Any time the vehicle is parked for several hours with the refrig-
erator operating, the vehicle should be leveled to prevent this
loss of cooling.
CAUTION
Do not park your RV on a slope for a longer period of
time. Absorption refrigerators use a gravity-ow system.
Being on an angle of more than a couple of degrees for ex-
tended periods of time stops the refrigeration and might
cause damage to the cooling unit.
CAUTION
It is important that you do not leave the refrigerator to
run idle and/or unattended for days or weeks.

ADJUSTING THE THERMOSTAT
The thermostat controls both the gas and electric operation.
Thus it is not necessary to reset each time a different energy
source is employed. The adjustable thermostat ranges from
1 - 3 where 3 signifies the coldest temperature setting. After
the initial start-up, adjust the thermostat by pressing the TEMP.
SET button repeatedly until the desired setting is displayed.
The refrigerator is equipped with an automatic Low Ambient
Control (LAC) function which guarantees the correct tempera-
ture in the freezer even at low ambient temperatures.
TURNING OFF THE
REFRIGERATOR
You can turn off your refrigerator by pressing the main power
ON/OFF button found on the control panel to the off position.
This will shut off all power to the refrigerator, including DC
power to the refrigerator.
If the refrigerator will not be in operation for a period of weeks
or put into winter storage, it should be emptied, defrosted,
cleaned and the doors left ajar. The ice trays should also be
dried and kept outside the cabinet.
If your RV is being put into winter storage, it is recommended
to either put your RV batteries on a battery charger or turn off
the vehicle’s main 12V switch. This will prevent the RV bat-
tery from discharging. (The refrigerator’s control system still
consumes a few milliamps even if it is turned off.)

FROZEN FOOD STORAGE
COMPARTMENT
This compartment is not designed for deep or quick freezing
of food.
•To prevent food from drying out, keep it in covered dishes,
containers, plastic bags or wrapped in aluminum foil.
•Meat or fish, whether raw or prepared, can be stored in the
frozen food storage compartment provided they are pre-
cooled first in the refrigerator. They can be stored about
three times longer in the frozen food compartment as com-
pared to the fresh food compartment.
•Quick frozen soft fruits and ice cream should be placed in
the coldest part of the compartment, which is at the bottom
of the aluminum liner.
•Frozen vegetables, may be stored in any part of the compart-
ment.
•To prevent frost buildup, which can reduce the efficiency,
wipe excess moisture off items being placed in the compart-
ment.

FOOD STORAGE COMPARTMENT
•Cool the refrigerator before placing any food inside. Never
put hot food or drinks into the refrigerator - cool them first.
•The food storage compartment is completely closed and
unventilated, which is necessary to maintain the required
low temperature for food storage. Consequently, foods hav-
ing a strong odor or those that absorb odors easily should be
covered.
•Vegetables, salads etc. should be covered to retain their
crispness.
•The coldest positions in the refrigerator are under the cool-
ing fins and at the bottom of the refrigerator. The warmer
areas are on the upper door shelves. This should be consid-
ered when placing different types of food in the refrigerator.
•Arrange all food in the unit to allow for free air circulation.
Do not overpack because a stuffed refrigerator must work
harder and will have higher cabinet temperatures.
•Do not leave the unit’s door open any longer than necessary.
This will reduce frost formation and increase the efficiency
of the refrigerator.
ICE CUBES
Ice cubes can be made in the freezer compartment. Place the
trays in direct contact with the bottom of the freezer compart-
ment. Ice will be made more rapidly if the thermostat is set at
its highest position, but be sure to move the thermostat back
to normal setting when the ice is formed; the refrigerator might
otherwise become too cold.

Put the door in airing position by:
(1) Open the door.
(2) Turn the integrated ap in the door handle to it’s end position.
(3) Close the door with the ap in it’s end position.
PRODUCT CARE
CLEANING
Always keep the refrigerator clean. Cleaning the refrigerator
is usually done after it is defrosted or put into storage. Use
lukewarm weak soda solution to clean the interior liner of the
refrigerator. Use warm water only to clean the finned evapora-
tor, gasket, ice tray and shelves.
NOTE! Never use strong chemicals or abrasives to clean these
parts, as the protective surfaces will be damaged. Do not spray
liquids near electrical outlets, connections or the refrigerator
components.
To keep the refrigerator operating efficiently and safely, peri-
odic inspection and cleaning of several components once or
twice a year is recommended:
•Check the lower vent, upper vent and area between these
openings for any obstructions such as bird/insect nests,
spider webs, etc.
•Make sure the refrigerator area is free from combustible
material, gasoline and other flammable vapors or liquids.
•Clean the coils on the back of the refrigerator. Use a soft
bristled brush to dust off the coils.
DEFROSTING
1. Shut off the refrigerator by pressing the main power
ON/OFF button.
2. Empty the refrigerator.
3. Leave the cabinet and freezer doors open and place
the drip tray under the finned evaporator.
Defrosting time can be reduced by filling the ice
trays with hot water and placing them in the freezer
compartment.
4. When all the frost has melted, dry the interior with a
clean cloth.
5. Replace the food. Set the thermostat to the coldest
setting for a few hours. Then, reset the thermostat to
the desired setting, usually at mid setting.
CAUTION
Do not use:
• A knife or an ice pick, or other sharp

CLEANING THE FLUE BAFFLE AND
BURNER
Inspect the flue baffle. It should be reasonably clean and free of
soot. Heavy soot formation indicates improper functioning
of the burner.
Be sure to check the burner
flame for proper appearance.
The flame should be light blue.
If it has a yellow tip, it means
that it is burning incorrectly.
Electrode
