Recharging operations:
to be able to charge the internal battery it is necessary to connect the universal switching adapter
(mod. UE 60140429SPA1 of FUHUA) to the electric network for approx. 360 minutes with the main switch to position 0.
The battery’s autonomy when fully charged is approx. 70 minutes with continued operations.
LIGHT INDICATORS:
The device is provided with a light indicator (directly on the LCD screen) which allows you to view the operation of the device,
autonomy of the battery, and the charge phase in progress.
The light indications, which appear during operation, are indicated in table I.
The charge cycle starts automatically it is necessary to connect the universal switching adapter (mod. UE 60140429SPA1 of
FUHUA) to the electric network. The charge occurs only when the motor of the suction unit is off.
DISPLAY IN CHARGE: this is on with white back-light and it remains on for the entire time. It switches off if there is no external
voltage. The charge phase lasts until the device is powered and the battery is kept at its maximum charge.
The large digits display “CHA”
.
