In CANADA, the installation must conform with:

1. Current CGA B 149 Gas Installation Codes

2. Current CSA Standard Z 248.4 GAS-EQUIPPED

RECREATIONAL VEHICLES AND MOBIL HOUS-

ING.

3. Any applicable local code

The unit must be electrically grounded in accordance with the current CANADIAN ELECTRICAL CODE C 22

Parts 1 and 2.

VENTILATION

The installation shall be made in such a manner as to separate the combustion system from the living space of the

mobii

home or recreational vehicle. Openings for air supply or for venting of combustion products shall have a minimum dimension of not less than 1/4 inch.

Proper installation requires one lower fresh air intake and one upper exhaust vent. The ventilation kiis shown in this instruction manual have been certified for use with the refrigerator models listed in the Table 2, “Certified Vent

System Kits” . The ventilation kits must be installed and used without modification. An opening toward the outside at floor level in the refrigerator compartment must be provided for ventilation of heavier-than-air fuel gases.

The lower vent of the recommended kiis is provided with proper size openings. The flow of combustion and ventilating air must not be obstructed.

The lower side vent is fitted with a panel which provides an adequate access opening for ready service ability of the burner and control manifold of the refrigerator.

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 checked for leaks with soapy water.

WARNING

DO NOT use a flame to check for gas leaks.

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 in excess of 1/2 psig, the refrigerator and its individual shutoff valve must be disconnected from the gas supply piping system.

When testing the gas supply system at pressures less than or equal to 1/2 psig, the appliance must be isolated from the gas supply piping system by closing its inividual manual shutoff valve.

In case detailed instructions on the installation and connection to the gas supply are required, contact your dealer or distributor.

ELECTRICAL CONNECTION

120 Volts AC Connection

The refrigerator is equipped with a three prong

(grounded) plug for protection against shock hazards, and 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 of the refrigerator (viewed from the rear) and approximately 6 inches from the floor

(see FIG. 3). This allows easy access through the vent door. The cord should be routed to avoid contacting the burner cover, flue cover or any other components that could damage the cord insulation.

IG. 3

12 Volts DC Connection

All

refrigerator models require a 12 volt DC supply (even though 2-way models are designed to operate on 120 volts AC and gas, a 12 volt DC control is required to maintain the automatic energy system). The DC lead connections are at terminals located at the rear of the refrigerator. (see FIG. 1). One lead is marked positive (+) and the other negative (-). 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.

12 Volts DC Connection 3-way models

The distance the current must travel from the battery to the refrigerator dictates the AWG wire size to be used.

Should the wire be too small for the distance, a voltage drop will result.

The voltage drop affects the wattage output of the 12 volt cartridge heater and resultant refrigerator performance.

Recommended wire sizes are shown below.

Maximum total conductor wire length in feet and meters.

After refrigerator is mounted in place (insuring a combustion seal at the front mounting flange), the unit can be secured by screws through the mounting flange and hole(s) provided at floor level in the rear. Caps are provided to cover the mounting flange screws.

Seal strips, provided with the refrigerator, must be in position behind the mounting flange after the refrigerator is installed in the wall enclosure. The seal must be continuos between the flange and the wall to assure combustion seal. Care should be taken when installing or removing the refrigeratorthat the strips are not disturbed or damaged.(See FIG. 8).

Lower Flange Installation

The lower flange is shipped as a loose part to prevent damageduring shipment. The part is to be attached after the refrigerator is set into the cut-out opening.

1. Install the lower flange by maneuvering it under and behind the bottom hinge plate, as shown in FIG. 4

(the hinge will be located on either the right or left side, depending on door swing preference).

The wires from the battery to the refrigerator must be of large enough size to handle the load. The connections must be clean, tight and free from corrosion. If not, a resulting voltage drop will cause a decreased cooling capacity.

INSTALLING REFRIGERATOR IN

ENCLOSURE

NOTE: 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.

CLEARANCES

Minimum clearances in inches to combustible materials are: Top 0; Side 0; Bottom 0; Rear 0.

The refrigerator must be installed in a substantial enclosure and must be level. When installing the refrigerator in the endosure, all areas within the recess in which the refrigerator is installed must be sealed.

Make sure 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 should provide a complete isolation of the appliance’s combustion system from thevehicle interior.

The refrigerator, designed for built-in installation, requires opening dimensions as specified in Tablel.

2. Once the lower flange is slipped around the hinge, the part will swing into place as shown in FIG. 5.

3. Secure the flange with screws provided.

FIG_ 5

TESTING LP GAS SAFETY

SHUTOFF

The gas safety shutoff must be tested after the refrigerator is connected to LP gas supply.

To test the gas safety shutoff, proceed as follows:

1. Start the refrigerator and switch to gas mode. (see start up instructions).

6.

Check that the gas flame is lit and the gas mode indicator lamp (C) is on.

Close the gas valve at the back of the refrigerator.

Wait for one minute. The check indicator lamp (E) should now be lit and the gas mode indicator lamp should be off.

Remove protection cover (see FIG. 1) and open the gas valve. Test that no gas comes through the burner jet. Use soupy water, rinse afterwords with fresh water. Be careful not to damage the burner jet, replace cover.

Make an ON-OFF operation with the main switch.

Normal gas operation should now return, operate for at least five minutes.

VENTILATION REQUIREMENTS

When installing the refrigerator in the enclosure, all areas at the front (sides, bottom and top) and within the recess in which the refrigerator is installed must be sealed so the resultant installation will isolate the appliance combustion system from the vehicle interior.

Certified installation requires that one lower combustion air intake and one upper exhaust vent be used. The specified vent kit for this refrigerator must be installed as directed by this manual without modification. Any deviation or substitution other than the specified vent kit will void this certification and the factory warranty of the refrigerator.

Venting must be in accordance with dimensions as shown in FIG. 6. Any deviation will result in non-certification.

Lower vent is to be utilized as a service entrance door.

Opening of lower vent must be flushed or below bottom of refrigerator.

The condenser and absorber tubes (see FIG. 6) must receive a continual supply of cooler air in order to maintain proper refrigerator cooling. A recommended 0” clearance between the back of the refrigerator and the coach wall helps the ventilation efficiency. The air passage (ventilation zone) from the lower vent door to the refrigerator coils and from the coils up through the roof vent must be unobstructed. If the air becomes trapped by obstructions, the refrigerator will start to lose its ability to cool. The proper ventilation zone, as shown in FIG. 8, will create a chimney effect to incure adequate circulation. It is important to block off the area above the refrigerator cabinet from this ventilation zone (see FIG.

8). Also, air space at the sides of the refrigerator should be minimized to prevent pockets of hot air from forming.

without adequate ventilation and/or with partial blockage of flue exhaust, incomplete combustion (on GAS operation) can cause carbon monoxide to form. Not only does the refrigerator lose efficiency, but a poisonous gas can result.

In the event of a prdpane leak, the properly installed lower vent door will allow the propane to " Weep " to the outside of the floor level, preventing large pockets of gas from collecting.

Lower vent and roof jack must be A.G.A./CGA certified for use with the refrigerator.

Roof jack opening must be centered directly above the flue and condenser. (See FIG. 6 and 7.)

INSTRUCTIONS FOR USE

HOW TO START THE REFRIGERATOR

Leveling

In an absorption refrigerator system, ammonia is liquified 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 hydrogen gas, which causes the ammonia to evaporate, creating a cold condition in the freezer.

The tubing in the evaporator section is specifically sloped to provide a continuous movement of liquid ammonia, flowing downward by gravity through this section. If the refrigerator is operated when it is not level and the vehicle is not moving, liquid ammonia will accumulate in sections 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.

Any time the vehicle is parked for several hours with the refrigerator operating, the vehicle should be leveled to prevent this loss of cooling. The vehicle needs to be leveled only so it is comfortable to live in (no noticeable sloping of floor or walls).

When the vehicle is moving, the leveling is not critical as the rolling and pitching movment of the vehicle will pass to either side of level - keeping the liquid ammonia from accumulating in the evaporator tubing.

OPERATION

Before starting the refrigerator, check that all the manual gas valves are in the ON position. DO NOT forget the manual shutoff valve on the rear of the refrigerator, see

FIG. 1.

This refrigerator is equipped whith a semi Automatic

Energy Selector (AMES) control system, which can be set to automatically select either 120 volt AC or LP gas operation, or if desired Lp gas only. On 3-way models the control system can manually be set to DC operation.

The refrigerator controls will work down to 9.6 volt DC.

WARNING

Most LP gas appliances used in recreational vehicles are vented to the outside of the vehicle.

When parked close to a gasoline pump, it is possible that gasoline fumes could enter this type of appliance and ignite the burner flame, CAUSING

A FlRE OR AN EXPLOSION.

FOR YOUR SAFETY, it is recommended that all LP gas appliances which are vented to the outside should be shut off when refueling.

DESCRIPTION OF OPERATING

MODES

THERMOSTAT

The thermostat on the refrigerator controls both the gas and electric operation, thereby eliminating the necessity of resetting each time a different energy source is employed.

After the initial start-up, the thermostat

should

be moved from “COLDEST’ to the desired temperature setting, usually about mid setting.

AUTO MODE

When operating in the AUTO mode, the AUTO mods indicator lamp (D) will illuminate. The control system will automatically select between AC and GAS operation with AC having priority over GAS. Either the AC indicator lamp (B) or the G

A

S indicator lamp (C) will illuminate depending on the energy source selected by the control system. If the control system is operating with AC energy and it then becomes unavailable , the system will automatically switch to GAS. As soon as AC becomes available again the control will switch back to AC regardless of the status of GAS operation.

GAS MODE

When operating in the GAS mode the AUTO mode indicator lamp (D) will be off and the GAS mode indicator lamp (C) will be illuminated. This mode provides LP gas operation only. The control system will activate the ignition system and will attempt to light the burner for a period of approximately45 seconds. If unsuccessful, the

CHECK indicator lamp (E) will illuminate and the GAS mode indicator lamp (C) will turn off.

To restart GAS operation, press the main power ON/OFF button (1) to the-OFF and then ON position. The control system will attempt a new 45 second ignition sequence.

If the refrigerator has not been used for a long time or the LP tanks have just been refilled, air may be trapped in the supply lines. To purge the air from the lines may require resetting the main power ON/OFF button (1) three or four times. If repeated attempts fail to start the

LP gas operation, check to make sure that the LP gas supply tanks are not empty and all manual shutoff valves in the lines are open. If the problem is still not corrected, contact a service center for assistance.

If the control is switched to AC or DC operation while the

CHECK indicator lamp is on, it will function properly, but the CHECK indicator lamp will not go off until the main power ON/OFF button is pressed to the OFF then ON position.

DC.MODE (3-way models only)

When operating in the DC mode the DC mode indicator lamp (A) will be illuminated. All other mode lamps will be off. The DC mode overrides all other operating modes.

If one of the other operating modes is desired, the DC selector button (2) must be in the UP (OFF) position.

BATTERY PROTECTION SYSTEM

The control system is equipped with a battery protection system. A steady illuminated DC mode lamp (A) indicates that sufficient voltage is present at the terminal block connections to operate the refrigerator normally.

If the input voltage is below approximately 12.8 volts DC or should it drop below 12.8 volts DC during operation, the DC mode lamp (A) will flash ON and OFF to signal a low battery condition. In this condition the control will continue to operate in DC mode for a maximum 10 minutes.

If the input voltage has not returned above 12.8 volts DC within this time, the control will terminate DC operation.

A second battery protection system will terminate DC operation immediately if the input voltage drops below

10.6 volts.

The DC mode lamp will continue to flash as long as the input voltage remains

below

12.8 volts. The input battery voltage must rise above 12.8 volts for 25 minutes before

DC operation can resume.

As soon as the input voltage rises above the required

12.8 volts, the DC mode indicator lamp will stop flashing, however, the control system will remain in the 25 minute delay mode. This delay is to allow sufficient time for the vehicle charging system to recharge the battery.

LIMP MODE OF OPERATION

This control system contains a feature where it will continue to operate the cooling system in the event of a failure of a major operating component. Two different modes of operation can occour in this category.

If for some reason the display

module

becomes non functional, the control system will revert to full automatic operation selecting the best energy source available with

AC,DC (3-way only) and GAS priority. The temperature of the refrigerator will be maintained at the MID position within normal temperature tolerances. The power module will continually attempt to re-establish operation of the display module.

The second limp mode of operation will execute when a failure of the temperature sensing device or associated electronic circuitry occurs. If this should occour, the control system will operate on the energy source selected via the control panel. The cooling unit will run continuously on the selected energy source. The refrigerator will continue to operate in this mode indefinitely or until a new sensor is installed and the system is reset.

HOW TO USE THE REFRIGERATOR

FOOD STORAGE COMPARTMENT

The food storage compartment is completely closed and unventilated, which is necessary to maintain the required low temperature for food storage. Consequently, foods having 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 cooling fins and at the bottom of the refrigerator. The warmer areas are on the upper door shelves. This should be considered when placing different types of food in the refrigerator.

FROZEN FOOD STORAGE

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 compartment.

This compartment is not designed for deep or quick freezing of food. 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 compared to the fresh food compartment. To prevent food from drying out, keep it in covered dishes, containers, plastic bags or wrapped in aluminium foil.

ICE MAKING

Ice cubes can be made in the ice tray placed in the freezer compartment. The tray should be filled with water to within 1/4" (5mm) from the top. For faster ice making, the tray should be placed in direct contact with the freezer bottom.

To release the ice cubes, seize the tray with both hands and twist the tray. Cubes not required should be replaced in the tray. Refill the tray with water and replace the tray on the freezer shelf.

Ice will be made more rapidly if the thermostat is set at its highest position.

It is a good idea to do this a few hours before the anticipated need for ice, but be sure to move back to normal setting, usually about mid setting when the ice is formed. Food in the lower compartment may be frozen if the setting is left on “COLDEST’ position.

DEFROSTlNG

Shut off the refrigerator by pressing the main power

ON/OFF button to the UP (OFF) position. Empty the refrigerator, leaving the drip tray

under the finned evaporator, and the cabinet and

freezer doors open.

Defrosting time can be reduced

by

filling the ice tray with hot water and placing it on the freezer bottom.

CAUTION

DO NOT use a hot air blower. Permanent damage could result from warping the metal or plastic parts.

DO NOT use a knife or an ice pick, or other sharp

tools to remove frost

from the freezer shelf. They can create a leak in the ammonia system.

When all frost is melted, dry the interior of the refrigerator with a clean cloth. Replace all food and set thermostat to the COLDEST temperature setting for a few hours.

Then reset the thermostat to the’desired setting, usually at mid setting.

CLEANING

Cleaning the refrigerator is usually done after it is defrosted or put into storage. To clean the interior liner of the refrigeratoruse lukewarm weak soda solution. Use only warm water

to clean the

finned evaporator, ice trays and shelves.

NEVER

use strong chemicals or abrasives to clean these parts as the protective surfaces will be damaged. It is important to always keep the refrigerator clean.

SHUT OFF - STORAGE PROCEDURE

Shut off the refrigerator by pressing the main power

ON/OFF button to the UP (OFF) position.

If the refrigerator will not be in operation for a period of weeks, it should be emptied, defrosted, cleaned and the doors left ajar. The ice tray should also be dried and kept outside the cabinet

Check the AMES control system by connecting/disconnecting 120 volt AC power, start/stop the engine, etc. Compare the operation with the operation described in description of operating modes. Side

NOTE: The following maintenance is required once or twice a year, but should only be done by a qualified serviceman who is familiarwith LP gas systems and refrigerators.

The LP gas pressure should be checked and the main regulator re-adjusted if pressure is incorrect.

The correct operating pressure is 11 inches of water column. The correct place to take the LP gas pressure is at the test port just ahead of the burner jet.

(See FIG. 16).

Inspect the flue baffle. It should be reasonably clean and free of soot. Heavy soot formation indicates improper functioning of the burner. The flue and burner both require cleaning in the following manner:

Unplug the refrigerator power cord from the 120 volt

AC outlet. (See FIG. 3).

Disconnect or shut off the 12 volt power to the refrigerator.

Turn manual shutoff valve to OFF.(See FIG. 1).

Remove cover from the burner housing. (See FIG.

1).

Disconnect the wire from the high voltage electrode.

Remove the burner mounting screws and remove the burner assembly. (See FIG. 16).

Remove the flue cap from top of flue tube and lift out the wire and spiral baffle. Clean the flue from the top using a flue brush. Blowing compressed air into the flue will not properly clean soot and scale out of the flue tube. Replace spiral baffle and flue cap.

Clean burnertube with a brush. Blow out bumerwith compressed air.

Before removing burner jet, clean burner area of soot and scale that fell out of flue tube. Remove the burner jet. Soak the jet in wood alcohol and blow it out with compressed air. Re-install and tighten burner jet.

NOTE:The color of the flame shall be clear blue over the slots of the burner. (See FIG. 17).

CAUTION

DO NOT use a wire or pin when cleaning the burner jet as damage can occur to the precision opening.

This can cause damage to the. refrigerator or create a fire hazard.

Reinstall burner, being careful that the end of the burner fits into the slot on the burner bracket. Check to make sure slots are centered under the flue tube and the thermocouple is positioned properly (tip of thermocouple extends over two slots of burner)

Be

sure

to reconnect the wire to high voltage electrode. Check the electrode for proper location and gap. (See FIG. 18).

TROUBLESHOOTING

The Refrigerator Does Not Cool Properly

Causes and remeides

Failure of refrigeration does not necessairily indicate that the cooling system is defective. Other factors governing its operation must be checked.

1.

1 a.

1 b.

1 c.

Common.

Fuse(s) blown, replace (see side 13).

Check level of refrigerator.

Venting problem. Restriction in airflow across cooling unit

1 d.

1 e.

Heavy frost buildup on evaporator fins, defrost.

If the refrigerator has been operating on gas and a loss of cooling is noted, convert the refrigerator to

AC power (see start up instructions side 10).

If the refrigerator has been operating on AC, switch to gas operation. This will determine if a component failure in the electric or gas controls is causing the cooling fault. After the refrigerator has been converted from one power source to the other (gas to

AC, or AC to gas) allow time to assure the unit is cycling properly. At the end of the period the freezer plate should start to cool.

if. A minimum of 9.6 volt DC supply present for the refrlgerator control system.

lg. The thermostat can not be moved from MID position to the desired setting. The display module has became nonfunctional. See limp mode of operation

(side 11).

1 h. The refrigerator is running continuously and cool to much.

The temperature sensing device has became non functional. See limp mode of operation (side 11).

2. Gas operation only.

2.1 The refrigerator will not operate on gas when AC is present.

The display module has became non functional. See limp mode of operation (side 11).

2.2 Burner jet clogged. Clean see Section Maintenance/service, item 2. Periodic maintenance,

Paragraph E. item 9.

2.3 flue baffle not inserted properly in flue tube (see side 3 FIG. 1).

2.4 Burner dirty. Clean. See Section Maintenance/service, item 2. Periodic Maintenance, Paragraph E.

item 8.

2.5 LP gas pressure low at burner.

Set main regulator so pressure does not drop below

11 inches water column at pressure test port (see side 13 FIG. 16).

2.6 Burner not located properly under flue tube, relocate.

2.7 Burner damage, replace.

ODOR FROM FUMES

CAUSES AND REMEDIES

A. The flame touches side of

the boiler due to disloca- tion of the burner. Relocate. Burner dislocation may also cause smoke and discoloring of walls and ceiling.

B. Burner damaged. Replace.

All the above instructions are to be followed closely. The refrigerator is quality-guaranteed. However, we are not responsible for any failures caused by improper adjustments and unfavorable installation conditions. Contact service point or distributor service dept. for assistance.
