5.7.1 FILTER and UV LAMP indicator light flashing
When the activated carbon filter or UV lamp needs to be replaced, the FILTER or UV LAMP indicator light on the
control panel will flash red. The unit will automatically shut off after the FILTER or UV LAMP indicator light flashes for
50 hours. If you do not reset them, the unit does not work (Fig. 5.7.1-1).
- Plug in the power cord.
- All the display indicator lights will flash for 2 seconds with a starting melody.
- After the melody stops, the CHECK indicator light will turn green from red.
- When pressing the POWER button, the FILTER or UV LAMP indicator light will flash red for 8 times with a beeping,
the unit does not work, you need to reset the FILTER or UV LAMP after replacement of activated carbon filter or UV
lamp.

Button contact circuit
When the trace is connected by the
sticker coat the remote control sends
out signal (One of the red or white
contact is OK).
Fig. 5.7.1-1 When you press the POWER button on the control panel or on the remote control the FILTER or UV LAMP
indicator light will flash red for 8 times with a beeping sound but the unit does not operate. You need to reset the unit after
replacing the activated carbon filter or UV lamp.

5.7.2 How to reset the FILTER or UV LAMP indicator
light
There are two ways to reset the replacement lights.
Reset with remote control
- Connect the power plug into the wall outlet.
- Press the POWER button on the remote control. If the
FILTER or UV LAMP indicator light flashes red, it tells the
remote control and the remote receiver of the unit are OK,
otherwise you will need to check the remote control or
remote receiver on the display circuit board.
- After replacing the activated carbon filter or UV lamp,
press the RESET1 button (For activated carbon filter) or
RESET2 button (For UV lamp) for 12 times continuously. If
the unit is reset you can hear a beeping sound and the unit
will work. If the unit still cannot be reset with the remote
control, you will need to change another remote control to
reset the unit (Fig. 5.7.2-1).
Note:
When the button contact circuit on the remote control circuit
board is touched by the silver coat inside the sticker, the
remote control sends out signals. If you press the button
once and release, the remote control sends out a signal
and the circuit board will carry out the desired function.
However, if you do not release the button after pressing or
the button sticker always contact the button contact circuit,
the remote control can not send out another signal and the
remote does not work. For instance, when you try to reset
the unit, if the size of the sticker coat is too big and always
cover the button circuit, even if you press the button several
times, the remote control just sends out a signal, leading to
the reset failure. The reason is the microprocessor needs
12 times signals from the remote control. To solve this
problem, you will need to change the sticker or past small
insulator tape around the button coat to decrease the size
of the coat. For more information, see
3.8 REMOTE
CONTROL.
