Safety
Warning: The safety precautions stated below are mandatory guidelines that must be
followed. LightObject will not be held responsible for damages or injuries resulting from
improper use of the Afterburner –water heater.
Make sure 110/220V setting matches your AC power input.
Casing is not waterproof. Unplug power cord before draining out water from the
Afterburner.
DO NOT power on device if water leaked/spilled into the after burner. Disconnect power,
then open the back cover to dry out water.
In Case of an Emergency: TURN OFF the POWER SWITCH of the device.
Q&A
Why is the water temperature of the Afterburner not consistent with my water chiller?
Temperature sensor in the After burner (water heater) and the temperature sensor in
water tank are at different locations. Temperature in the afterburner is usually a little bit
higher than the water tank temperature.
I have water flowing but the water flow reading is really low?
Maybe INLET and OUTLET connections are swapped. Water flows in the wrong way.
How do I know if the power button is on or off?
If it is pressed in, it is on. Also, light turns on behind the button.
How do I know if it is heating?
When it is heating, an icon will keep flashing on the bottom right corner of the display. In
addition, you will be able to see the temperature keeps rising. Larger volume of water
takes longer to heat up. For a 4.5L tank, temperature will rise 1C in 50-60 seconds.
