●● Do NOT allow children to play with product or with fixed controls (if applicable).

●● ABSORPTION-COOLING-SYSTEMS. FIRE, BURN, OR INHALATION HAZARD. Do NOT fracture or puncture cooling unit.The cooling unit is under pressure and contains ammonia, sodium chromate, and other chemicals. Repeated or prolonged exposure to sodium chromate could cause organ damage or cancer. Exposure to a high concentration of ammonia refrigerant could causepulmonaryedema(fluidinlungs);chemical burns to eyes, lungs, and skin; and could cause a fire (when exposed to open flame).

●● COMPRESSOR-COOLING-SYSTEMS. FIRE, FROSTBITE, OR INHALATION HAZARD. Do NOT fractureorpuncturecoolingunit.Thecooling unit is under pressure and contains tetrafluoroethane refrigerant, and may contain other chemicals. Contact with liquid refrigerant could cause irritation or frostbite to eyes and skin. Exposure to a high concentration of refrigerant could cause cardiac arrhythmia (irregular heartbeat). A high concentration of refrigerant could cause a fire (when exposed to open flame).

●● FIRE OR INHALATION HAZARD. If refrigerator stops working and/or it emits an ammonia smell, immediately turn refrigerator OFF (if it is safe to do so), leave the vicinity, and contact a qualified Service Center.

●● CARBON MONOXIDE HAZARD. This product canproducecarbonmonoxide.CarbonMonoxide has no odor and can kill you. The burner and flue system MUST be kept clean. Failure to obey this warning could result in death or serious injury.

REFRIGERATOR OVERVIEW

A.Absorption Cooling System

See “General Safety Messages” for information on absorption cooling systems, and consequences of exposure to refrigerant.

When turning on the refrigerator, you should adjust the thermostat (excludes DM2652 & DM2852 - NOT adjustable) to the coldest temperature setting. The cooling cycle may require an extended running time before cooling effect is observed.

B.Keep Refrigerator Level

(ABSORPTION COOLING SYSTEM ONLY)

For optimal cooling performance, an absorption refrigerator must be level. If the refrigerator operates in a noticeable out-of-level condition for several hours, loss of cooling performance will occur.

When RV is parked and absorption system is operating, the RV must be level enough to live in and feel comfortable.

The RV does NOT need to be PERFECTLY level, but there should be no noticeable sloping of RV floor or walls.

It is NOT critical for refrigerator to be level while RV is traveling. The rolling and pitching motion of travel helps keep the absorption system balanced.

C.Operating Refrigerator At High Altitude

All gas appliances experience lowered efficiency (or rating) at high altitude. This is a direct result of lower atmospheric pressure and oxygen levels, and is not a defect of the refrigerator.

Reduced cooling performance and burner outage may occur at altitudes higher than 5500 feet above sea level (while operating on LP gas). Always operate refrigerator on electric power at altitudes higher than 5500 feet.

D.Purging Air From The Lines

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, turn the refrigerator off and on by pressing the ON/OFF button. If the flame is not lit within 45 seconds, turn the refrigerator off and back on again. This procedure can be repeated 3 to 4 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 that all manual shutoff valves in the lines are open. If the problem persists, turn the refrigerator off and take it to a Service Center.

E.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.

It is important that you do NOT leave the refrigerator to run idle and/or unattended for days or weeks.

F.Automatic Energy Selector System

The refrigerator is equipped with an automatic energy selector system.The user turns the refrigerator on and then, the refrigerator automatically selects the most suitable energy source available, either 120 VAC or LP gas operation. The system can be set by the user to be fully automatic (AUTO mode is selected) or to operate on LP gas only (AUTO mode is off).

On 3-way models, the control system can manually be set to DC mode (DC operation). The DC mode overrides all other operating modes.

The refrigerator controls will work down to 9.6 VDC.

REFRIGERATOR OVERVIEW

H.Modes Of Operation

1.AUTO MODE

When operating in AUTO mode, the AUTO mode indicator lamp is illuminated. The control system will automatically select between AC and GAS operation. AC has priority over GAS. Should AC become unavailable, the system automatically switches to GAS.

As soon as AC becomes available again, the control will switch back to AC, regardless of the status of the GAS operation.

If the CHECK indicator lamp is illuminated, the controls have failed to ignite the burner in the GAS mode. To restart an ignition attempt with the CHECK lamp illuminated (or to turn off the CHECK lamp), press the ON/OFF button OFF and back ON again. The control system activates the ignition system and makes attempts to light the burner for a period of approximately 45 seconds. Should 120 VAC become available while the CHECK indicator lamp is on, the CHECK lamp will not turn off until the ON/OFF button is pressed OFF and then ON again.

2.GAS MODE DM2652 & DM2852:

When operating in GAS mode, the AUTO mode indicator lamp will be off.

DM2662, DM2663 & DM2862:

When operating in GAS mode, the GAS Mode indictor lamp is illuminated.

This mode provides LP gas only. The control system activates the ignition system and attempts to light the burner for a period of approximately 45 seconds. If unsuccessful, the CHECK indicator lamp will illuminate.

To restart GAS operation, press the ON/OFF button to OFF and then back ON. The control system attempts a new ignition sequence.

3.DC MODE DM2663

When operating in DC mode (3-way models only), the DC mode indicator lamp is illuminated and all other lamps are off. To select another operating mode, turn off the DC mode by pressing the DC selector button. The DC lamp is turned off.

When there is no charging of the house battery, switch to AUTO mode or GAS mode, since running the refrigerator on 12 VDC will quickly drain the battery.

4.LIMP MODE OF OPERATION

In the event of a failure of a major operating component, the control system will continue to operate the cooling system.

DM2652 & DM2852:

If the control can not read the temperature sensor and control the preset temperature, the control will run the cooling unit continuously at the energy source available. The refrigerator continues to operate in this mode indefinitely or until a new sensor is installed and the system is reset.

DM2662, DM2663 & DM2862:

Two modes of operation can occur:

a.The first limp mode of operation will execute if the display module becomes nonfunctional. The control system reverts to full automatic operation, selecting the best energy source available with AC, DC (3-way only) and GAS priority. The temperature setting is maintained at the mid position. The power module will continually attempt to re-estab- lish operation of the display module.

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