6, it shall be over 7.5V)
，
so model machine computer panel can recharge battery; if battery
electric quantity is lower than 10.5(for old products with mode of 6, when it is lower than
7.5V), a machine starts to recharge the battery, it takes about 5 days to finish recharging
battery; if the machine still meets the problem of battery alarm, the battery needs to be
replaced. When the machine is not used, battery switch must be turned off, otherwise, after
battery electrical quantity is exhausted, the battery cannot be recharged, which will cause the
battery to be scrapped;
3. Alarm of dirty condenser:
There are three kinds of cases that may cause the alarm,
First, new machine: as there is a sensor on condenser, when condensing temperature exceeds
38
℃
(exceed 32
℃
in earlier stage), at this time, dirty condenser alarm may occur; When a
user just starts a machine, as the temperature inside refrigerator is high, cooling load is large,
heat release is also large, at this time, condenser temperature is too high, the signal sent by
sensor to computer panel thinks that the condenser is dirty, so alarm occurs; after the
machine has operated for a period of time, the alarm will disappear automatically.
Deposal method: communicate with users and explain the cause of alarm and machine
features.
Second, ambient temperature is too high, so the condensing temperature of machine is
correspondingly too high, and exceeds 38
℃
, at this time, the machine will also occur the
phenomenon of dirty condenser alarm;
Deposal method: reduce the machine’s ambient temperature.
Third, the machine has been used for a long time, or user environment is quite dirty, there is
too much dirt on condenser filter screen, the heat dissipation of condenser is poor, at this
time, the machine will sound the dirty condenser alarm.
Deposal method: clean off the dirt on condenser filter screen.
