＊Green power light indicates that power is supplied. If the light is not lighten, there is a
possibility either power is not supplied, or the special thermal fuse in cigarette lighter
plug burns out. Please check accordingly. (Refer to Fig 6). Whether polarity is correct
or not, as immediate burning out fuse is designed for safety, in case of reversed
polarity.
＊When not using the fridge, remove the plug from the cigarette lighter socket to prevent
unnecessary discharge of your car battery.
＊Pay due attention to correct polarity, the inner contact of cigarette lighter socket
adapter must be connected to the positive supply, while the outer (negative) contact is
connected to earth. (Nearly all modern vehicles are wire on the negative earth system,
but there may still be older vehicles and imported ones where the positive earth system
is employed.)
DIRECT WIRING FOR PERMANENT VEHICLE INSTALLATION(OPTIONAL)
① TWIST THE LEAD WIRE
Please use separate positive and negative cables, twisted together in a spiral form,
between your battery and the DC outlet socket to avoid further radio interference
during DC. operation. (see Fig 4)
② CONNECT FRIDGE DIRECT TO BATTERY
Any switches and leadwires for other electrical equipment should not be shared with
wiring between your fridge and battery. (Other equipment can generate high voltage
pulses which may cause transistor damage to the fridge power supply.)
③ To avoid radio noise and absorb surge pulse case of radio noise and large surge pulse
insert of the capacitor. (10000 μ F) (see Fig 5)
