About the Power Supply
•lug the power cord into a 230V outlet with at least a rating of 10A and power surge protection.
•Do not plug in multiple devices into the same power outlet or extension cord simultaneously.
•lease ensure that the power plug and power outlet are clean and dry.
•Do not use the equipment if there is any damage to power cord, plug or the outlet.
•Damaged parts are only to be repaired or replaced by 3M certified professionals.
•In case of water leakage, please unplug the device immediately.
•Always switch off and unplug the equipment before inspection, repair or replacement of its
components.
Issues During Inst ll tion/Use
•Do not install in direct sunlight or outdoors. The equipment is designed for indoor use only. Areas with
high moisture/humidity or dust may damage the equipment. Direct sunlight and high temperature may
result in color changes.
•Do not place the equipment on uneven surface.
•Do not place it in an area with potential for gas leak, or near a heating device. Do not place any
heating device on top of the dispenser.
•Do not place the device in an area where temperature falls below 0º C as the internal components may
freeze, causing system breakdown. In the event that the water source is frozen and cannot be supplied
to the device because the surrounding temperature has fallen below 0 ºC, please turn off the hot water
system for safety.
•Do not place any objects on top of the equipment.

CAUTION
Issues During Inst ll tion/Use
•Do not use excessive force to pull the hot and cold water levers. It may cause damage or malfunction.
•Do not clean the equipment using strong chemicals such as benzene or thinner.
•Do not disconnect the hose at the back of the equipment or move the equipment while it is in
operation, as this may lead to water leakage and potential breakdown.
•Do not use the filtered water as water for fish bowl or aquarium. Filtered water may not be suitable for
fish.
•Ensure all tubing and fittings are secure and free of water leakage.
•If the equipment has not been used for a long period of time, completely drain out the tank. Fill it with
water and drain it again before use.
•Lock the panel by pressing the Auto Dispense button for 3 seconds to prevent accidental changes to
the settings.
• The disposable filter cartridge MUST be replaced every 12 months, at the rated capacity, or if a
noticeable reduction in flow rate occurs (whichever is sooner) to ensure its effectiveness.
