adequate wiring (4mm to 6mm wire) connected via an in-line
fuse (minimum 15A) to the vehicle’s battery.
In vehicles equipped with dual-battery systems, it is preferable to
connect this socket to the auxiliary battery.
The supplied cable is suitable for two types of DC sockets ;
the more common “cigarette lighter” socket or the “Hella” type
socket. In order to fit the cable to the “Hella” socket, remove the
RED cap.
If the cable is used in the “cigarette lighter” socket, the RED cap
must be securely clipped in place.
Combination plug
Fuse replacement
If the Weekender fails to operate when
mains voltage is applied, check the input
fuse located under the power connection
point.
Slide the fuse draw open with a flat object
such as a screwdriver and remove the
fuse.
Replace fuse with same type and rating
to ensure safe operation. (3.15A 250V)
The Weekender can operate from a 12 volt battery or
230 Vac mains power.
To operate the Weekender on mains power, connect
the supplied cable to the 3-pin input on the side of the
refrigerator and then the the 230V supply.
Ensure the plug is correctly inserted in order to prevent
poor connections.
When using battery power, simply connect the polarised
DC cable to the corresponding input on the Weekender
and plug into the vehicles’ DC supply or to a fully-
charged battery.
230V AC
12V DC
Note that both 12V DC and 230V mains
can be connected at the same time.
When this is done, the Weekender will
automatically run on mains power.

# of
flashes Fault description
The Weekender is fitted with a unique battery monitor on the control panel.
This monitor shows the voltage level applied to the 12V input. (Such as a battery)
As the battery becomes discharged, the monitor will show the drop in voltage , this
allows the user to be aware of available battery capacity.
In a vehicle, if the engine is running, the monitor should show a voltage between
13.2V and 14.2V. If this voltage is below this level, it is possible that the charging
system is damaged or that there is poor wiring.
Alarm: The monitor is fitted with a low-voltage alarm. This alarm will warn the user
of excessive battery discharge. In this case, the battery should be recharged as
soon as possible.
During a low-voltage alarm, an audible warning will be heard. (If enabled)
Enabling the alarm: The audible alarm is OFF by default but can be enabled by pressing
the button for 3 seconds. When enabled, the red ALARM light will be illuminated.
Perform the same procedure to disable the audible alarm.
REVERSE POLARITY - This indicator identifies that the power applied to the 12V input has the
incorrect polarity. Check all wiring connections for correct polarity.
POWER PACK OVER-TEMPERATURE - The Weekender has mult-stage over-temperature
protection. In the event that the electronics overheat, the refrigerator will automatically slow-down
(over-temperature light will flash). If temperatures continue to increase, the refrigerator will be
shut-down as a protection feature (over-temperature light will be permanently illuminated)
