OPERATION OF
THE CONTROLLER
The temperature controller fitted to your Fridge/
Freezer provides the ability to set the desired
temperature level and three (3) 12V DC battery
cut-out levels to protect your car's battery.
The digital read out will provide information on
the cabinet & set temperature, battery voltage at
the fridge, as well as the voltage level that the
controller has been set to.
The electronic controller has been programmed
to maintain an average of the set temperature.
The compressor will start up when the internal
cabinet temperature increases 0.5 to 1.5
degrees above that selected and will run until the
temperature is 0.5 to 1.5 degrees below the set
temperature.

SETTING THE TEMPERATURE
When your Fridge/Freezer is first connected to
AC or DC input the digital read out will show
the factory setting of -18 degrees, to adjust the
temperature follow these steps:
STEP 1.
Push the "SET" button once, the digital read out
"G" will then start to flash
STEP 2.
Push B "up" or C "down" until you reach the
desired temperature – DO NOT push "SET"
again. Now that the temperature has been
selected it will flash three (3) times on the digital
read out then return to the current internal
cabinet temperature.
The indicating light "E" will be green indicating
that the cooling function will commence.
To check the set temperature press the "SET"
button. The selected temperature will flash on the
digital read out three (3) times.
To change the temperature setting repeat steps
1 & 2.

BATTERY CUT-OUT
12V DC OPERATION ONLY
The control system allows for the voltage cut-out
to be set to three (3) different settings depending
on the environment & situation that the appliance
is being operated in. Low voltage supply to the
appliance can result in poor cooling performance
and damage to the supply battery.
Most modern vehicles require a minimum of
10.5V DC to start correctly and ensure that all
electronic & safety features will operate correctly.
To ensure that suitable battery voltage can be
maintained the controller has been programmed
to offer three (3) cut-out levels - 11.8, 10.7 &
10.0V DC.
To set the battery cut-out to the required level
follow these steps:
STEP 1.
Push the "BATT" button once, the digital read out
"G" will show the current setting.
STEP 2.
Push button "A" or "C" to adjust the setting.
The display will flash four (4) times with the
selected setting. To check press "batt" once and
the selected setting will flash and then return to
current voltage input.
When the appliance is disconnected
from the power source the battery cut-out
remains at its last setting.
LED LIGHT & ALARM
Your Fridge/Freezer is fitted with an LED light to
illuminate the cabinet in the dark. The LED will
turn on when the door is opened and turn off wh
AC POWER CONNECTION
The Fridge/Freezer is supplied with an approved
3 pin AC Power Lead and this must not be
modified or lengthened.
When connecting to AC power ensure that the
power socket is switched "off". Plug the AC
Power Lead into the AC socket on the appliance
and then plug the other end of the AC Power
Lead into the AC supply and switch on.
DC POWER CONNECTION
The Fridge/Freezer is supplied with a 1.5m
power cord fitted with a 12V DC outlet fitting. It
is recommended that this lead is not lengthened
as this may result in a voltage drop and reduced
performance.
When connecting the appliance to DC power
ensure that the power socket is switched "off".
Plug the 1.5m power cord into the DC socket
on the appliance and then plug the other end
of the 1.5m power cord into the DC supply and
switch on.
For optimum performance & efficiency, it is
important that the appliance has a reliable
10amp fuse protected DC supply in good
condition. Direct connection to the battery is
recommended and reduces the risk of voltage
dropping to the appliance.
It is recommended that the correct sized
Automotive Electrical Cable is used for the
direct connection and that this includes a
10amp fuse; do not use resetable circuit
breakers. It is important that the correct cable
size is used for the installation of the DC supply
as over distance the voltage can decrease if the
incorrect sized wire is being used.
