Gas Output Display: display the value of HHO gas production. (l/hr)
Over-pressure indicator light: When the pressure gauge value exceeds 0.2Mpa, the light
will show red, the machine stops producing gas. In the process of carbon cleaning,
over-pressure indicator light should not show red, if the light shows red, it might be
because the setting of gas production is too high, or gas outlet magnetic valve can not be
opened, or the middle of the supply gas line blocked.
Over-heating indicator light: electrolytic power temperature exceeds the set temperature,
the light will show red, the machine stops producing gas. Maybe it is caused by the
cooling fan does not work or poor heat dissipation. The over-heating light does not show
red under normal circumstances.
Over-temperature indicator light: When the electrolyzer temperature exceeds the set
temperature, the light will show red, the machine stops producing gas. Maybe it is caused
by electrolyzer cooling fan does not work properly, the over-temperature light does not
show red under normal circumstances.
Power supply indicator: when the light is green, that indicate the system power supply is
Lacking Water Indicator: a. when the water level in the electrolytic cell is below minimum
level, Lacking Water Indicator will show red; b. The carbon cleaning solution in the water
tank is almost consumed, if not add solution on time, Lacking Water Indicator will show
red, the machine will stop gas production in protected status.
Operation Manual of Kingkar HHO carbon cleaning machine
Adding Water Indicator: when the water level of water tank is low, Adding Water Indicator
will show green. At this time, you need to open the cover at the top of machine, add water
to the water tank through the filling opening. Adding until the indicator light off, should stop
adding water. If Adding Water Indicator light turns on, but without timely adding solution, it
will cause to lack of solution and the machine will automatic shut down.
Pump Running Indicator: when the system detects the water level of electrolytic cell is low,
the machine will add water from the water tank automatically, Pump Running Indicator will
show green this time.
Note: If Pump Running Indicator light and Adding Water Indicator does not light, It means
there is a fault with the solution supply system, mainly for the pump valve failure, or the
water level sensor’s pollution.
