Product safety
•Do NOT touch exposed wires with your bare hands, especially when operating from
240VAC mains power
•It is dangerous to touch the plug or power input panel with wet hands
•When operating the refrigerator in a vehicle or boat, ensure that the power supply
circuit is appropriately sized and fused
•The installation of AC power sources in a vehicle, trailer, caravan, or marine vessel
should be carried out by a qualified person
•Ensure the correct power supply is connected
•Do not immerse in water
•Do not place any electrical devices inside the refrigerator
•Only qualified personnel are to perform servicing, contact your agent for information
•This product is not intended for use by young children or infirm persons unless they
have been adequately supervised by a responsible person to ensure they can use the
appliance safely
•Young children should be supervised to ensure that they do not play with the
appliance
•The appliance must not be exposed to rain
General notes and operating tips
Always provide good ventilation to your Powertech Portable fridge/freezer, especially
around the rear section where the compressor is situated. Allow an air gap of at least
200mm around the rear of the unit and approximately 100mm gap to the right hand side
(where the ventilation slots are on the fridge body).
Avoid humidity inside the refrigerator: humidity inside the appliance can form frost and
impair cooling, therefore defrost regularly.
Never clean the refrigerator under running water or in a dishwasher.
Avoid placing the refrigerator near a heat source as this will impair cooling performance and
efficiency.
Always place the refrigerator on a flat surface away from edges.
When installing the unit in a vehicle or boat, ensure it is adequately secured.
REMEMBER: to maximise the efficiency of the refrigerator, avoid opening the lid too often,
and keep the fridge reasonable well filled, but not over filled.
Suitable for camping use.

Power connections
The appliance may be connected to more than one source of energy; there are
provisions for both 12/24Vdc power input and 240VAC mains power input at
the rear of the unit, allowing for operation on either DC or AC power sources.
Both AC and DC power sources can be connected at the same time, the unit
will automatically revert to 240VAC mains power as the priority.
The refrigerator unit must always be connected to an adequate power supply
and DC connections must always be fused and wired with appropriately sized
cable to avoid excess voltage drop. See table below for recommended cable
sizing from battery to fridge:

Low voltage battery protection
This unit has an automatic low-voltage battery protection feature that will
automatically switch off the compressor if the DC supply voltage drops below
the Cut-Out level, and will automatically re-start operation when the DC supply
voltage comes back up to the Cut-In level. See table below:
Battery Protection 12V Cut-Out 12V Cut-In 24V Cut-Out 24V Cut-In
LOW 10.2V 11.2V 21.6V 23.0V
MED 10.7V 11.7V 22.6V 24.0V
HIGH 11.7V 12.7V 24.6V 26.0V
NOTE: If your refrigerator is cutting out prematurely, it could be due to
the low voltage protection being set too high, or your DC supply
wiring is not suitable enough to carry the current required. Check
supply wiring suitability and consider adjusting the battery
protection switch at the rear of the unit accordingly.

Operation
Temperature control range: -18ºC ~ 10ºC
Temperature display range: -20ºC ~ 45ºC
To operate, plug in the DC or AC power cord to the unit and connect the cord
to a suitable power supply. Press the ON/OFF power switch to turn the unit on
and the temperature display panel will illuminate and display the current
temperature inside the refrigerator.
Press the ▲and ▼buttons to set your desired fridge temperature, ▼will
reduce the temperature and ▲will increase the temperature, whilst the
temperature display will show what your current set temperature is. Once the
display shows your desired temperature, don’t press any buttons and after 3
seconds the display will flash and the unit will beep to confirm your setting.
Pressing both ▼and ▲at the same time will switch the display from ºC to ºF.
Pressing the ECO/MAX running mode button will toggle the operating mode
between ECO and MAX operating modes, with the indicators lighting up
according to which mode is currently selected.
ECO: This mode reduces power consumption and is best used once the
fridge has cooled down to operating temperature
MAX: Best used to cool down the internal temperature of the fridge
rapidly, however this mode will consume more power.
NOTE: If power is lost, the refrigerator will automatically re-start when power
is restored.

Cleaning & maintenance
Before cleaning, the power should always be switched off and disconnected.
Clean the unit inside and out with a damp cloth. For stubborn dirt, using some
sodium bicarbonate dissolved in lukewarm water may be used.
Never use abrasive products, detergents or soap. After washing, rinse with
clean water and dry carefully.
When storing the unit for a long period of time, do NOT fully close the lid. This
will prevent mould and odours.
Troubleshooting
If the unit will not turn on:
•Check the power supply (voltage may be too low)
•Check all connections from battery to fridge
•Check the fuse
•Check the unit is turned ON
If contents of the fridge are freezing:
•The temperature has been set too low
Poor refrigeration performance:
•Too much food has been put inside the unit
•Temperature of the food put inside the fridge is too high
•Lid is not closed properly
•Lid seal is damaged
•There is poor ventilation around the fridge (see info on page 4)
•Ambient temperature is very high
•Temperature is not set correctly
There is a “water flow” type of noise from inside the unit:
•This is normal, caused by the flow of refrigerant
There is a noise from the unit:
•Unit is not on a flat level surface
•Check for vibrations in surrounding objects
