2 Requirements for installation and notice
*The location to install this equipment must have AC power, water inlet and water outlet connection,
floor drain and sewage discharge outlet.
* All water pipe and electric connections used are recommended to meet relevant national standard;.
*Keep this equipment away from acidic substance or gas to avoid corrosion.
*Please use AC 220V / 50Hz single-phase electric power rather than any other power supply. The
power socket should be grounded and equipped with overload protection units (such as breaker or
safety fuse).
*The equipment should be installed vertically, not upside-down or horizontally. And it should be kept in
an upright position in transit. Do not allow it to be tilted while handling to avoid damages to
equipment.
*The recommended water incoming pressure is 172-862 kPa (25-125 psi). Booster bump or
pressure-relief valve is to be installed either below or above this standard.
*Make sure that the sewer drainage remains clear and that there is a distance between the drainage
pipe and sewage water to prevent back flow of sewage water into the eqeuipment. Do not insert
drainage pipe into the sewage water. Size of floor drain pipe should not be less than DN40.
*To avoid leakage in the system or pipeline over time, take cautious on the height and angle when
connecting the pipes to avoid stress.
* Take care when using pliers or pipe wrenches to tighten plastic fittings, as overtightening may cause
damages to the threading.
* Before connecting the inlet water pipe, clear any residual impurities and dirt in the pipeline first. Turn
off the main valve then connect the pipes to the equipment.
* Recommended to install system indoor or under shelter.For outdoor installation, it is recommended
to build awning and take protective measures for the body andthe pipeline. Prevent it from direct
sunlight, rain, wind, heat and cold, pollution, theft or animal damage.
* The temperature of the incoming water should be between 4.4-37.8oC (40-100oF). If the water
heater is installed after the softener, one-way check valve should be installed at the pipeline to
prevent backflow of hot water.
*Make sure that the softener is installed and maintained by 3M or 3M authorized dealer and installers.
