5. INSTALLATION
5.1 General installation
The following points should be considered when choosing a location to install your
ARB Fridge Freezer.
A minimum clearance of 50mm must be maintained on all sides of the fridge freezer.
Whether the installation is permanent or temporary, the fridge freezer must be
attached to secure anchorage points.
The ideal mounting position for the fridge freezer is on a flat, horizontal surface. If
the fridge freezer is subject to sideways angles (e.g. heal on a boat), it can withstand
a sideways angle of 30°.
Avoid placing the fridge freezer near sharp or hot objects.
Avoid placing the fridge freezer near loose objects that could fall on the cabinet and
obstruct its operation.
Never operate the fridge freezer near flammable liquids or vapours.
Avoid turning or storing your fridge freezer on its side.
5.2 Permanent and temporary mounting.
The recessed stainless steel bracket at each end of your ARB Fridge Freezer has been
engineered as a Tie-down point. ARB recommends that the ARB Tie-down system be
used to securely mount the fridge freezer to solid anchorage points. Figure 3 shows
the ARB Tie-down system installed with the ARB Fridge Slide.

6. OPERATION
6.1 Before use
Before starting your fridge freezer for the first time, it should be cleaned inside and out
with a damp cloth. Please refer to the chapter “Cleaning and maintenance” for further
details on maintaining your fridge freezer.
6.2 Carrying your fridge freezer
Your ARB Fridge Freezer is supplied with handles at each end of the cabinet. These
handles should be used to lift and move the fridge freezer.
WARNING - The lid or latch MUST NEVER be used to lift or move the fridge freezer.
CAUTION - The fridge freezer should always be lifted by at least two people.
6.3 Opening your fridge freezer
To open the fridge freezer lid:
Place your hand under the latch.
Push down on lid surface slightly to release pressure on lid latch.
Use fingers to lift and release latch.
While holding latch open, pull lid open and rest lid in vertical position.
To close the fridge freezer lid:
Close lid and apply pressure on lid surface until the latch engages. You will hear
a click as the latch engages.
The lid is now closed with the latch engaged.
6.4 Connecting your fridge freezer
6.4.1Connecting to 12/24V DC
Your ARB Fridge Freezer can be operated on either 12V or 24V DC. Your fridge freezer
is fitted with a control circuit to prevent polarity reversal and possible short-circuiting
when the unit is connected to a battery.
To connect your fridge freezer to a 12 V or 24 V DC supply, plug the 12/24V power
lead into the DC power socket on the back panel of the fridge freezer as shown in
Figure 4. Connect the free end of the power lead to a 12 V or 24 V DC supply.
FIGURE 4.

6.4.212/24 V DC wiring requirements
To ensure optimum performance of your ARB Fridge Freezer, it is important that your
wiring system is capable of carrying the required load. The accessories wiring system in
many vehicles is not adequate for such a task.
ARB recommends that a dedicated wiring circuit be installed to power the fridge
freezer. This circuit should be as short as possible and be connected directly to the
power supply via a 10 Amp fuse.
For an automotive or marine installation, ARB recommends that the wiring circuit be
connected to an isolated power supply like an auxiliary battery system. This will prevent
discharge of the main starting battery.
For cable lengths up to 6m, ARB recommends a minimum cable diameter of 6 mm
automotive cable (4.6mm2).
For cable lengths greater than 6m, ARB recommends that you consult a qualified
technician for advice on the correct cable diameter.
6.4.3Connecting to an engine driven generator
Please take note of the following points before connecting your ARB Fridge Freezer to
an engine driven generator.
The generator must be fitted with an automatic voltage regulator. It must supply
a standard, pure sine wave AC voltage, without fluctuation in voltage or
frequency (eg 120 VAC~60Hz or 240 VAC~50Hz).
When using the DC output from your generator, a battery of correct voltage (12
or 24V) must be connected between the generator and the fridge freezer.
The fridge freezer should be turned off when starting and stopping your
generator.
CAUTION –Some engine driven generators are not suitable for powering your fridge
freezer.

6.4.412/24V DC power socket
The plug on your 12/24V DC power lead has a removable adaptor collar. With the
collar in place as shown in Figure 5, this plug will fit into a conventional vehicle
accessories power socket (cigarette lighter). With the adaptor collar removed as shown
in Figure 6, this plug will fit into an ARB 2 pole auxiliary power socket.
FIGURE 5. FIGURE 6.
ARB highly recommends that this 2 pole connection be used for all 12V DC and 24V
DC connections of a fridge freezer. This will provide a positive and secure connection
between your power source and your fridge freezer.
The following points should be considered when choosing a location for your fridge
freezer auxiliary power socket.
Position the power socket as close to the fridge freezer as is practical.
Position the power socket in a convenient location that will allow the user to easily
connect and disconnect the plug from the socket.
Position the power socket in a protected location away from dust and moisture.
Position the socket high in the vehicle to prevent it from becoming wet should the
vehicle ingest water.
NOTE –If the plug or adaptor collar is removed and the fridge freezer is hard wired
into a 12V or 24V DC circuit, a 10 Amp inline fuse must be included in the circuit.
