Installation and Operating Instructions

Installation
For best performance at high ambient temperatures, there must be free air circulation over the cooling unit at the rear of the freezer.
Ensure that there is a free air space above the freezer and that the flue (chimney) on top of the cabinet is not covered in any way. Do not place the freezer in a space where air circulation is restricted. Follow “clearance” instructions.
This UNIQUE 2 appliance has been certified as a portable camping appliance in North America it must be used as a portable camping appliance for use outdoors in sheltered area. While using on electrical operation this unit can be used in an enclosed area but must still be protected from moisture as comply with all clearances.
For installation, for maintaining proper clearances from combustible material to the freezer, the following minimum clearance must be observed:
Clearances
Minimum clearances to combustible materials are: Top 16”, Sides 2”, Rear 4” Tank Holder Installation Instruction for UGP-2

1. Take out 2 pcs hose clamps, 2 pcs bolts, the regulator and instruction manual.
2. Install these 2 pcs hose clamps on the cabinet side.
3. Insert tank into hose clamps and tighten until snug. Tank should not fall out of holder when fridge is tipped forward.
4. Use soap water to check whether there are bubbles on gas inlet connector, if not, then start to use the refrigerator.

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 the full width and depth of the appliance. Keep appliance area clear and free from combustible materials, gasoline and other liquids with flammable vapors.
WARING – DO NOT USE FLAME TO CHECK FOR GAS LEAKS
Levelling
Ensure the freezer is leveled by using a 2ft level; the operation of this unit uses an absorption system which requires the appliance to be level in order to operate effectively.
Connecting to Gas Cylinder
The freezer is designed for a 20# steel propane self-contained fuel cylinder of not more 4.6 gal (20lbs) capacity. The cylinder(s) must be constructed and marked in accordance with the specifications for LP-gas cylinders of the U.S. Department of Transportation, DOT SPEC. 39 (49CFR 178.65).
Connecting of Gas Supply

1. Use supplied regulator and hose to connect your appliance to the gas supply.
2.  Hook up the 5/8”-18UNF connection to the back of your appliance using a backup wrench.
3. Attach the regulator cap to the tank inlet connection and ensure it is tight.
4. After connecting, all gas connections must be checked for leaks. For this, put a soapy solution on all gas connections, turn on the gas cylinder manual valve and watch for bubbles. Never use an open flame to check for leaks.

Note: The gas supply system must incorporate a pressure regulator to maintain a supply pressure of not more than 12” water column and no less than 11” water column. (Max setting).

• The cylinder be disconnected when the appliance is not in use
• The gas must be turned off at the supply cylinder. Storage of an appliance indoors is permissible only if the cylinder is disconnected and removed from the appliance. Cylinders must be stored outdoors out
• The cylinder supply system must be arranged for vapor withdrawal
• If in excess of 1 lb (0.45 kg) of liquid fuel capacity, must include a collar to protect the cylinder valve
• So not store a spare LP gas cylinder under or near this appliance
•  Never fill the cylinder beyond 80 percent full
• If the instructions in l(i) and l(ii) are not followed exactly, a fire causing death or serious injury may occur;

General Operating Instructions
Importance of Leveling a Freezer
The freezer must be adjusted to a vertical position in both directions. In an absorption  refrigeration system, ammonia is liquefied in the finned condenser coil at the top rear of the freezer. The liquid ammonia then flows into the evaporator (inside the freezer) and is exposed to circulating flow of hydrogen gas, which causes the ammonia to evaporate, creating a cold condition in the freezer.
When starting this freezer, the cooling cycle may require 6 to 8 hours of running time to begin cooling before the cooling unit is fully operational, you can then begin slowly loading the compartment.
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 freezer is operated when not level, 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. Warranty will not cover recharge/rebuild if caused by not running the freezer level.
This freezer operates LP Gas (Propane), 110V (Electricity) and 12V DC
Gas Operation
“Start Up” Procedure
After initial installation, servicing, or changing gas cylinders etc., the gas pipes may contain some air which should be allowed to escape by briefly turning on the freezer.
This will ensure that the flame lights immediately.

1. Make sure that all valves between the gas container and the freezer are open.
2. Turn selector switch (E) to gas.
3. Depress the safety device control (A) and hold it down while immediately depressing the electronic igniter button (C).
4.  Check the flame indicator (B) to see whether the flame is alight.
5.  Keep the safety device control (A) depressed for a further 10-15 seconds.
6. Release the safety device control (A) and again check to see that the flame is alight.
7.  Adjust the thermostat knob (D) to desired temperature setting after 6 to 8 hours of operation.
8.  To terminate gas operation, turn selector switch (E) to OFF position.

Electronic Ignition Module Location The electronic ignition battery module is located at the back of the appliance at the bottom left side while facing the back of the appliance.
If the battery requires changing, turn knob to the left to expose the battery, remove AAA battery and replace with new one (positive facing outwards), replace the knob and turn to the right to close.
Shut Down Procedure – LP Gas
A. Turn selector knob “E” to “OFF” position.
B. Shut the gas off at the LP-gas supply cylinder when the appliance is not in use.
C. If the freezer will not be in operation for a period of weeks, it should be emptied, defrosted, cleaned and the lid left open.
110V Operation

1. Make sure that the gas valve is turned off at the tank.
2. Ensure the electrical cord is plugged into a grounded outlet.
3.  Turn the selector switch (E) to “AC” position. AC indicator light will illuminate.
4. Adjust the thermostat knob (D) to desired temperature setting after 6 to 8 hours of operation.

12V DC Operation

1. If 110 Volts or LP gas is not available, the freezer can work with DC12V (3Way models only).
2.  Make sure that you turn the main power switch (E) to “DC” position. Then you can connect the 12VDC power to the terminal block which is available in the rear bottom part of the freezer.
3. DC operation is not as efficient as LP Gas or AC operation. DC electric should not be used to initially cool the freezer. Only use DC when the other modes are unavailable (for example; while in transit). When you start to use AC or gas supply, make sure that you disconnect the DC power input.

CONTROLS – See Fig. #1 for description of controls Thermostat
The freezer cooling temperature is controlled by a combination thermostat that can be adjusted by turning knob “D” to different settings to maintain the desired freezer temperature when operating on either gas or 110V. Knob “A” also incorporates a safety device which automatically shuts off the supply of gas if the flame goes out. The electronic ignition C discharges sparks onto the burner when the button is pushed. See Figure #1

1. “MAX” Setting of the Thermostat: In gas operation, the thermostat allows the burner to remain on high flame continuously. (turn clockwise), and in 110V operation the element will stay on until the desired temperature is reached inside the freezer.
2.  The thermostat can be adjusted between “4” and “1” to obtain the desired freezer temperature. When the thermostat reaches the set temperature, it will reduce the burner back to bypass operation or shut the element off in 110V operation.
3.  In DC operation the freezer will only maintain the temperature that’s already been achieved. There is no thermostatic function.

How to Use the Freezer

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.
Defrosting
Frost will gradually accumulate inside the freezer surfaces. It must not be allowed to grow too thick as it acts as an insulator. Check the formation and when it exceeds ½” thick, defrost the freezer.
Shut off and empty the freezer, leaving the freezer lid open.
DO NOT USE A HOT AIR BLOWER, PERMANENT DAMAGE COULD RESULT. DO NOT USE A KNIFE, ICE PICK, OR ANY OTHER SHARP TOOLS TO REMOVE FROST FROM THE FREEZER COMPARTMENT.
When all frost is melted in the freezer it should be wiped up with a clean cloth. Replace all frozen food and set the thermostat to its Max position.
Cleaning
Cleaning the freezer is usually done after it is defrosted or put into storage. To clean the interior liner of the freezer, use a lukewarm water and weak soda solution.
Never use strong chemicals or abrasives to clean these parts as the protective surfaces will be damaged. It is important to always keep the freezer clean. Dishwasher detergent is recommended.

Maintenance & Service

The user should be aware of service that must be done on a regular schedule to keep the freezer operating properly. Installation must be by a licensed gas fitter in accordance with local codes or must comply with Propane Installation Code CAN/CGA-B149.2 (latest edition)

• Keep appliance area clear and free from combustible materials, gasoline and other liquids with flammable vapors.
• Do not obstruct the flow of combustion and ventilation air, ensure clearances are followed.

FREEZER REMOVAL
Before working on the freezer, shut off the gas supply. Disconnect the gas supply line at the rear of the freezer. Always use a backup wrench when loosening and tightening this connection. Disconnect freezer from 110V source.
Warning: To avoid electrical shock always unplug your freezer before cleaning. Ignoring this may result in injury.
PERIODIC MAINTENANCE
Before working on freezer, shut off the gas supply. Disconnect the gas line at the rear of the freezer. Always use a backup wrench when loosening and tightening this connection.
To keep your freezer operating effectively and safely, periodic inspection and cleaning of several components is recommended once or twice a year, sometimes more often depending on environment.

• It’s important to keep the area at the back of the freezer clean. Clean the coils on the back of the freezer. Use a soft bristled brush to dust off the coils.

Note: The following maintenance is required at least once or twice a year at least, more often based upon usage/environment.

• Check all connectors in the complete freezer LP gas system for gas leaks. The LP gas supply must be turned on. Apply a non-corrosive bubble solution to all LP connections. The appearance of bubbles indicates a leak and should be repaired immediately by a qualified serviceman.

WARNING – DO NOT USE FLAME TO CHECK FOR GAS LEAKS
PROCEDURE FOR CLEANING THE COOLING SYSTEM FLUE
WARNING: Carbon Monoxide can be hazardous to your health. Gas appliances may emit excessive Carbon Monoxide if the freezer’s burner, burner orifice, and the flue tube are not regularly cleaned. To prevent Carbon Monoxide, the burner, burner orifice, and the cooling system’s flue tube must be cleaned at least once a year and after all prolonged (seasonal) shut-down periods. Refer to the following cleaning procedures, or contact a qualified installer, your dealer.

1. Before cleaning, cover the burner to protect it from dirt;
2. Remove the spiral flue baffle from the flue tube.
3. Using a stiff brush or fine emery cloth, clean the spiral flue baffle of debris.
4. Clean the inside of the flue tube with a flue brush. Inspect burner after cleaning.
5. Re-install the spiral flue baffle. Insure the spiral flue baffle is securely in place. The spiral flue baffle is required for efficient cooling while operating in the gas mode.

CLEANING THE BURNER
Take off the protection hood and do the following:

1. Clean the openings and the burner screen with a wire brush
2.  Clean and inspect the electrode and thermocouple. If either is corroded, have it changed. Check that they are well attached and if necessary tighten the screws
3. Check that the spark is being created by pressing the electronic ignition button on the control panel.
4.  Before removing burner orifice, clean burner area of any soot, scale or dirt Remove the orifice and soak it in alcohol (isopropyl alcohol or thinners) and blow it out with compressed air. Do not use thin objects to either clean or unblock the injector. Re-install and tighten burner orifice.
5.  Replace burner

Warning – DO NOT use a pin or wire when cleaning the burner orifice as damage can occur to the precision opening.
This can cause damage to the freezer or create a fire hazard. It will also create extremely dangerous levels of carbon monoxide.
Visually check burner flame to ensure you have a clean burning flame, this is represented by a blue looking flame, a yellow/orange flame represents a dirty burner or orifice and needs to be cleaned. WARNING – Button (A) Fig#1, page 7, must be manually depressed to allow gas pressure to flow to the burner orifice. Be sure to apply the leak check solution before depressing this button. DO NOT allow any open flame, sparks, smoking, etc. in the area of the test. DO NOT depress (A) for over 30 seconds. If leak occurs, correct problem, recheck with leak test solution then light the burner according to the instructions under Operation Instructions, Chapter 2

Food Storage Ideas

FROZEN FOOD STORAGE

• The freezer compartment should be kept at 8.6°F (-13°C) at a 77°F (25°C) room ambient
• A freezer operates most efficiently when it is slowly loaded to 2/3 full.

PACKAGING FOODS FOR FREEZING

• To minimize dehydration and quality deterioration, use aluminium foil, freezer wrap, freezer bags or airtight containers.
• Force as much air out of the packages as possible and seal them tightly. Trapped air can cause food to dry out, change color, and develop an off-flavor (freezer burn).
• Wrap fresh meats and poultry with suitable freezer wrap prior to freezing.
• Do not refreeze meat that has thawed.

LOADING THE FREEZER

• Avoid adding too much warm food into the freezer at one time. This overloads the freezer, slows the rate of freezing, and will raise the temperature of frozen foods.
• Leave a space between the packages, so cold air can circulate freely, allowing food to freeze as quickly as possible.

Care and Cleaning
Keep your freezer clean to prevent odor build-up. Wipe up any spills immediately and clean both sections at least twice a year. Never use metallic scouring pads, brushes, abrasive cleaners or strong alkaline solutions on any surface. Do not wash any removable parts in a dishwasher.
NOTES:
Do not use razor blades or other sharp instruments, which can scratch the appliance surface when removing adhesive labels. Any glue left from tape or labels can be removed with a mixture of warm water and mild detergent, or, touch the glue residue with the
sticky side of tape you have already removed. Do not remove the certification/serial plate.
