3. Electrical operation:
When running on electricity the cooling
unit
operates by means
of
two separate 75 W heating
elements, one for 120 V
a.c.,
the other for 12 V
d.c..
a)
120
Volts
a.c.:
Warning: Electrical earthing instructions:
This appliance is equipped with a three-pin (earthing) plug to protect you from shock
hazards and should be
plugged
directly
into a properly earthed three-pin socket. Do not
cut or remove the earthing pin from this plug.
The lead is approximately 5 feet bng and an earthed three-pin socket should be installed
in an accessible position within reach of
the
plug.
Do
not use any extension leads!
b),
12 Volts d.c.:
The current drawn is
7,O
amps. If the box is run on the car battery it is
recommended
that
the refrigerator be operated only when the car engine is running. If the engine is stopped,
the car battery will lose power and become fiat.
The 12 V supply is protected by a fuse of maximum 10 amps.
The fuse-holder is fitted into the control panel. Check that a correct fuse
is installed.
4. Starting the refrigerator:
Do not operate the unit on two
or
more power ‘sources (i.e. gas and 120 V or 12
V)
SIMULTANEOUSLY. The cooling unit will not operate properly in this case and damage may
be
caused.
