Ventilation requirements

General information

Ventilation is one of the requirements for proper cooling unit operation. The installation should be made in such a manner 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. The ventilation kits shown in this manual have been certified for use with the different models as displayed in the “Certified Vent System Kits” table.

The ventilation kits must be installed and used without modification! 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 combustion and ventilating air must not be obstructed.

CAUTION

It is of especially importance that the airflow around the burner housing, the boiler insulation and the flow 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.

The lower side vent is fitted with a panel, which provides an adequate access opening for ready serviceability of the burner and control manifold of the refrigerator. This should be centered on the back of the refrigerator.

installation procedure

Installing the refrigerator

Be careful when installing the refrigerator models NDM1062 & NDR1292. These are equipped with the latest vacuum insulated panel technology. The insulating panels are located on the top, back, bottom, sides and doors. If the surface is punctured, loss of insulation will occur, resulting in poor refrigerator performance.

For a proper installation, follow these instructions:

•Make sure the floor is solid and level.

•The refrigerator must be level and installed in a substantial enclosure.

•Do not install the appliance directly on carpeting. Carpeting 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.

•RM2451, RM2454, RM2551, RM2554, DM2652, DM2662, DM2663, DM2852, DM2862, DM3862, NDM1062 & NDR1292

A wood strip must be in place across the up-
per opening of the enclosure. The top frame
of the refrigerator will be anchored to the
wood strip with screws.	7OODDSTRIP

•When installing the refrigerator in the enclosure, all areas within 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.

RM2351 and RM2354: Apply a sealing strip to the foremost floor of the enclosure.

Be careful not to damage the sealing strip when the refrigerator is put in place!

Securing the refrigerator

It is important to follow the sequence in securing refrigerator in enclosure since failure in doing so can cause leakage between the frame and cabinet. Any space between the counter, storage area or ceiling and top of the refrigerator greater than 1 1/2 inches should be blocked. The heat produced at the rear of the refrigerator will become trapped in this space, making the top of the refrigerator hot and reduce the efficiency of the refrigerator.

After the refrigerator is put in place (ensuring a combustion seal at the front frame), the refrigerator is to be secured in the enclosure with screws (not included).

RM2351 & RM2354

Install the five screws in the following order:

1.Four screws installed through the front frame.

(To cover the screw heads, use the plugs in the parts bag.)

2.One screw installed in the rear base.

installation procedure

Drain water hose

Drill a hole through flooring. To avoid damage to the hose, the hole must be positioned so that the hose doesn’t touch the boiler casing. Seal around the hose that goes through the drilled hole and ensure that it does not kink when run through the floor. Check to make sure that the supplied hose is long enough in order for the water to drain outside of the vehicle. If not, the installer will have to supply the extra length of hose.

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 examined for leaks using a solution of liquid detergent and water.

6! warning

EXPLOSION HAZARD. Never use an open flame to check for gas leaks. Failure to heed this warning could cause an explosion resulting in death or severe personal injury.

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.

RM2354, RM2454, RM2554, DM2662, DM2663, DM2862, DM3862, NDM1062 & NDR1292

To test the gas safety shut off, follow these steps:

1.Start the refrigerator. 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.

4.Wait for approx. 6 minutes. The CHECK indicator lamp should be lit and the GAS mode indicator lamp should be off.

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 are present at the burner jet orifice, rinse it with fresh water. Be careful not to damage the burner jet orifice.

11.Allow the burner to operate for a minimum of five minutes.

RM2351, RM2451, RM2551, DM2652 & DM2852

To test the gas safety shut off, follow these steps:

1.Start the refrigerator without connecting to

120VAC.

2.Check that the gas flame is lit. In AUTO mode, the AUTO mode indicator lamp is on.

3.Follow steps 3-11 in the previous instruction.

Electrical connection

120 V 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. It should be routed to avoid direct contact with the burner cover, flue cover or any other components that could damage the cord insulation.

To allow easy access through the vent door, it is recommended that the receptacle is placed like this:

12V DC connection

RM2451, RM2551, DM2652 & DM2852: These refrigerator models are not designed for 12V DC operation of the cooling system. However, 12V DC must be supplied to operate the controls.

RM2354, RM2454, RM2554, DM2662, DM2663, DM2862, DM3862 & NDM1062: These refrigerator models require a continuous 12V DC supply to maintain the automatic energy system.

The connection is made to the positive (+) and negative (-) terminals of the terminal block on back of the refrigerator.

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. Ensure the connections are 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.

For 3-way models, the voltage drop affects the wattage output of the 12V cartridge heater and the refrigerator performance. The 12V DC heater is fused with a 30 amp. in-line blade fuse.
