INSTALLATION
Unpacking and Cleaning
Remove all packaging and securing tapes from the appliance. To avoid injury and damage to the appliance, be
extremely cautious when using sharp or pointed tools to complete this task. You may want to leave the lid open
allowing the compartment to ventilate for 20-30 minutes to get rid of residual odors. Check with your local
Environmental Agency for recommendations on recycling packaging materials in your area.
Positioning
•The skin of the refrigerator is the condenser and will become warm when the compressor is running. There should
be adequate ventilation space between the refrigerator and neighboring walls. At least 3 inches (7.5 cm) is
recommended.Never add insulation to the exterior of the appliance.
•For best efficiency, place the refrigerator in a cool location and avoid prolonged direct sunlight on the appliance.
•Always keep the air vent openings of the compressor housing cover (Lower right side or rear) free from dust and
obstructions.
Leveling
Leveling is not required for proper operation of this unit. However, some units have adjustable feet if leveling is
desired. Wood shims can also be used if necessary.
Installing the door handle
Some models may ship without the door handle installed. If this is the case, the handle and mounting
hardware will be located inside the refrigerator.
Electrical Connection (12 or 24VDC only!)
•The positive wire is colored Red or is black with a red stripe. The negative wire is black.
•THE APPLIANCE MUST BE CONNECTED TO A 12V OR 24 VDC POWER SOURCE ONLY, such as a
battery or charge controller. The unit will automatically operate on either 12 or 24 VDC. The user does not
need to make any adjustment.
•This unit will not operate directly from a PV solar module. Contact SunDanzer if you prefer this option.
•If the polarity is reversed, the unit will not be damaged, but will not run. If the unit is equipped with a light,
the light will operate even with reverse polarity.
•Since there is no established standard DC plug, the power cord has bare terminations. The user must provide a
meaning of connection this wire to the power source. Using wire nuts, or adding a ring or spade terminal is
common.
•This connection should not become hot when the units is running. If it does, rework the connection to insure
better conductivity.

Fuse
A fuse is required in order to protect the wiring. A
standard automobile fuse is recommended, and the
fuse should be wired to the positive (“+”) side of the
system close to the positive battery terminal. For
12V operation, use a 15A fuse, and for 24Voperation
use a 7.5A fuse.

The most common customer call is related to using inadequate wiring such that the compressor will
experiences a low voltage situation at start-up and not run.
Low Voltage Disconnect
The compressor electronics include a low voltage
disconnect feature. If the input voltage to the
appliance falls below 9.6V (in 12 V mode) or 21.3V
(in 24 V mode), the compressor will shut-off. Once
the voltage increases above 10.9V (in 12V mode) or
22.6V (in 24V mode), the compressor will resume
normal operation.
This feature is designed to protect the system battery
from experiencing too low a depth of discharge.

Compatible Solar System
The unit is designed to run from a 12 or 24V DC power source such as a deep cycle or solar battery. The battery is
typically charged using wind or solar PV power. The energy required to run the SunDanzer fridges and freezer is listed

on the website. In general, the refrigerator models require 120-200 W-hr/day in a 32C ambient. Freezer models require
300-600 W-hr/day.
OPERATION
Starting the Appliance
Once the wiring is complete and the refrigerator has 12 or 24VDC available, the unit will turn on automatically. The
thermostat is also an on/off switch for the unit. When the dial is fully counter clockwise, the fridge will be off.
The compressor is very quiet and it may be difficult to hear it running.
Initial Cooldown
Once on, the refrigerator will reach operating temperature in about 20 to 40 minutes. Once it is cold, you made add
food, but if a large quantity (> 5fg) of warm food is added, it may take hours to cool.
Ambient Temperature/Climate
This refrigerator is designed to operate in an ambient temperature range of 41F (5C) to 110F (43C). It can operate
outside this range, but with reduced reliability.
Temperature Control
The temperature within the appliance is controlled by a mechanical thermostat situated on the lower front or side of the
cabinet. When you first start the appliance, we suggest that you turn the thermostat to a medium setting. The best way
to measure the average internal temperature is to measure the temperature of a bottle of water located near the middle of
the refrigerator. The normal operating temperature of a refrigerator is 39F (4C) and the normal operating temperature of
a freezer is -5 to +10F (-21 to -12C). The refrigerator will draw noticeably less power at warmer settings.
Opening and Closing the Lid
The lid is fitted with a uniform sealing strip to prevent warm air and moisture from entering the appliance compartment.
Be sure that the lid seal is free from obstructions and forms a complete seal around the rim of the cabinet. Overfilling
and/or unlevel installation of the appliance will prevent a good seal. It might be hard to open the lid immediately after
the lid is closed. This is due to a vacuum which is created after warm air entering the refrigerator cools and contracts
after the door is closed. This pressure difference will equalize in a few seconds.
Loading
Do not over fill! Leave some space at the top so the door can always fully close. To assist the cabinet in cooling large
loads quicker, keep the cabinet full of product (or containers of water). It will also help to cool your food quicker if your
food is packaged in smaller containers rather than large ones. It is best to never package food more than 5cm (2 in,)
thick. The center of food packaged thicker than this will cool slowly and may spoil. Leave air spaces between food

items for quicker cooling. Items in contact with the interior walls will cool faster and can freeze if the thermostat is set
to a colder setting.
Baskets
Larger models include baskets. These baskets can be configured to hang from the top lip of the refrigerator or can stack
in the bottom by adjusting the plastic tabs on the baskets.
Door Lock
Some units are fitted with a door lock. Keys for the lock will be located inside the fridge. If the lock need to be
replaced, contact SunDanzer or an authorized SunDanzer dealer for replacement parts.
Shutting down or taking unit Out of Service
Turning the thermostat fully country clockwise will turn the unit off. If the unit is to be off for an extended period
(more than 6 hours), the interior should be thoroughly cleaned and dried. It is recommended to leave the lid slightly
open to provide ventilation.
DEFROSTING (Freezer models only)
•Before any cleaning or repositioning is carried out, you must DISCONNECT the appliance from the electrical
power supply.
•Transfer the cold food to a cooler or simple box to keep it cold during the defrosting.
Freezer Defrosting
The appliance compartment will become progressively covered with frost. This should be removed periodically with a
plastic scraper (provided with some units). However, when the ice becomes very thick on the interior walls, complete
defrosting should be carried out. Perform this operation when the appliance is empty and disconnected from the power
supply.
To carry out complete defrosting:
1. Disconnect the appliance from the electrical supply.
2. Remove any stored food and store in coolers, or wrap in several layers of newspaper and store in a cool place.
3. Leave the lid open.
4. Remove the plug from the defrost water drain located in the bottom interior of the cabinet.
5. To accelerate the defrosting process, place a bowl of hot (not boiling) water inside of the appliance and close the
lid.
6. The defrost water can be collected by placing a pan under the defrost drain located on the exterior bottom front of
the cabinet.
7. When defrosting is complete, wash and dry the interior thoroughly. Be sure to replace the plug on the defrost
water drain.
8. Reconnect the appliance to the electrical supply and leave running (while empty) for at least 2 hours allowing the
interior to cool sufficiently.
9. Replace the previously removed foodstuff.
CLEANING AND MAINTENANCE
Scheduled Maintenance and Preventative Maintenance
There is no scheduled or preventative maintenance with the SunDanzer chest products, simply clean as required.
Never use sharp metal tools to scrape or chip off frost from the interior compartment as this could
damage the appliance beyond repair. Do not use heat sources, such as electric or gas heaters to
complete the defrost process.
ATTENTION: A rise in temperature of frozen food products during defrosting may shorten
their safe storage life.

Internal Cleaning
Wash the inside of the appliance with luke warm water and a mild soap. Never use abrasive or corrosive cleaning
agents, steel wool, scouring sponges, chemical cleaning agents, or highly perfumed cleaning products to clean the
interior as these will damage the surface and leave behind a strong odor. A sponge, towel, or soft brush is
recommended. Washing with a mixture of two table spoons of baking soda to 1 quart (1.14L) warm water. After
cleaning, thoroughly rinse and dry.
External Cleaning
Wash the outside of the cabinet with warm water and a mild soap or detergent. Do not use abrasive or corrosive
cleaning agents, chemical cleaning agents, steel wool or scouring sponges to complete this task as it may cause damage
to the surfaces.
Interior Light
Some units are equipped with an interior light which can be changed without the use of tools. Be careful to always use
a dual voltage 12/24 VDC light bulb. If a 12/24V bulb is not available, use a 24V light rated at 10 watts of less. It will
be dim with a 12V system, but it will be safe!
HINTS & TIPS
Normal Operating Sounds
•A thermostat controls the compressor and you may hear a 'click' when the thermostat cuts in and out.
•You may hear faint gurgling or bubbling sounds when the refrigerant is pumped through the refrigerant coils.
•The compressor is quiet and can only be heard in a quiet room.
Energy Saving Advice
•Do not install the appliance close to sources of heat, such as a stove, boiler, heater, chimney, etc, and avoid
exposure of the appliance to direct sunlight.
•Also allow adequate spacing around the cabinet for air circulation (3in. or 7.5cm)’Warmer thermostat setting
require less energy to maintain
•Avoid unnecessary frosting in the cabinet by packing all food and liquids in airtight packages or containers.
•Always keep foodstuff stored in tightly sealed packaging or containers, and allow some space for air to circulate
around each item.
•Avoid keeping the lid open for extended periods of time or opening the lid too frequently as warm air will enter the
cabinet and cause the compressor run unnecessarily often.
•Ensure there are no obstructions preventing the lid from closing properly and forming a tight seal.
TROUBLE SHOOTING
Before contacting a service technician, SunDanzer or your local product dealer, check the following points.
If you call out a technician to a fault listed below, or to repair a fault caused by misuse, abuse, or faulty installation, a
charge will be made even if the appliance is under warranty.
SYMPTOM
SOLUTION
Appliance connected
to power, but does not
operate
•Check if 12 or 24V DC is present at the appliance. If not check all connections
and the system battery voltage.
•Check that the polarity is correct “+” is connected to “+” and “–“ to “–“.
•Check the fuse. If blown, replace with a new one.
•The main common problem with installations is voltage drop to the compressor
which causes the unit to fail to start due to “Low Voltage.” Typically, a
connection is not as tight as it should be, or the wire size to the compressor is too
small. The low voltage problem occurs at the instant of start-up and is
sometimes difficult to detect with a volt meter because the event is very quick
(<100 ms)
Appliance is
operating, but the
interior is not cold.
•It may take 20 minutes for the interior of the cabinet to become cool.
•Check that the thermostat control knob is turned to the correct setting relevant to
room/ambient temperatures.
•Has too much warm foodstuff recently been placed in the cabinet? If so, it is
normal to not be cold and it will take time to return to temperature.

•Does the cabinet have adequate ventilation around the side walls allowing it to
transfer heat properly? (See Installation Section).
•If the compressor is running and the unit does not cool, then it is most likely low
on refrigerant.
Appliance is running
too cold.
•Is the thermostat set too cold?
•Turn the thermostat back and forth as this might correct the problem, but order a
replacement thermostat.
•Is the thermostat capillary tube fully inserted in the holder? This requires
removing the compressor compartment cover to inspect. When the thermostat is
properly inserted, you will feel hard stop which indicates the capillary is fully
inserted.
•If the ambient temperature is colder than the refrigerator set-point, the
refrigerator will eventually become too cold. There is no heater in the
refrigerator.
The lid will not open.
•Has the lid just been opened? If so, wait 10-20 secind for the air pressure to
equalize and try again.
Light will not turn on
•If the interior light (if present) does not turn on, check to see if the refrigerator is
receiving power. If it is, the light need to be replaced.
Water on interior floor
•This is normal. Wipe dry with a cloth or paper towel.
Water on floor near
fridge
•The condensate drain is equipped with a drain cap. If this cap is removed, water
will leak from the fridge to the floor around the fridge. If the drain cap becomes
lost, find a suitable plug to close the drain hole. If the cap is missing, the energy
consumption and rate of moisture build-up will increase.
Condensate around the
door seal.
•If there is condensate around the door seal, check the door to make sure the seal
is fully closing and not damaged or blocked.
Excessive frost and ice
has built up.
•Is the weather hot and humid? If so, this will increase the rate of frost build up in
the cabinet.
•Ensure that foodstuff is properly packaged.
•Check that the lid is closed and has a good seal, and that nothing is preventing
the lid from closing properly.
•Large quantities of food have recently been placed in the cabinet/and or the lid is
frequently opened.
•Ensure that advised periodic cleaning has been carried out.
Noise
•See normal operating sounds (above).
Fault Indicator light
Some models include a fault indicator light on the compressor. This light can be seen through the side or rear cover
without removing the cover. The number of blinks indicates the type of fault. The following is a table of the fault code
meanings. This table applies to units with a SECOP compressor.
