4. INSTALLATION INSTRUCTIONS
________________________________________________________________________________________________________________________________________
4.1 Precautions
The following conditions are required for the installation of the carbon filter system:
• Installation and working space : Not less than 350x 350 mm, 170 cm high
• Distance between centers of inlet and outlet: 10.2cm
• Distance between power source and carbon filter: No greater than 2m.
• Level platform or floor.
• Constant electrical supply to operate the controller.
• Total minimum pipe run to water heater of ten feet (three meters) to prevent backup of hot
water into system.
• Local drain or tub for discharge as close as possible.
• Water line connections with shutoff or bypass valves.
• Must meet any local and state codes for site of installation.
• Valve is designed for minor plumbing misalignments. Do not support weight of system on
the plumbing.
• Be sure all soldered pipes are fully cooled before attaching plastic valve to the plumbing.
• Room to access equipment for maintenance and adding media to tank.
• After some maintenance work on pipe network, the initial effluent from the faucet often
contains a lot of rust and pollutants. Therefore, after each occasion of water supply
stoppage, please open the bypass valve or bypass pipe to drain out dirty water; or install a
filter before this filter system to ensure that only clean water will enter the water filtration
system. Generally, influent turbidity should be controlled at less than 5NTU.
• Generally, the carbon filter is installed after the water meter at the entrance of indoor tap
water; the water meter can then be used as a gauge for determining the amount of water
treated.
• Hot water can cause damage to the internal processing system of the carbon filter. Users
who connect hot water boiler or instant water heater after the carbon filter must install a
check valve between the carbon filter and their water heating system, and ensure that their
water heating system is equipped with temperature and pressure control safety devices.
• When installing carbon filter in newly renovated premises where water has not been
used before, first open the water faucet to discharge the water for at least 10 minutes to
completely flush away any construction debris, corrosion rust and dirt. This will prevent
dirt from entering the connected carbon filter during installation and cause damages to
internal filter materials.
• A manual valve should be installed just before the inlet and outlet respectively. A bypass
valve or bypass pipe should be installed between the inlet and outlet to facilitate normal
water usage during maintenance of the carbon filter, or to enable direct usage of non-
treated water when needed.
• It is recommended that a pre-filter be installed before the inlet to prevent contaminated
water from entering the carbon filter system, thus affecting its operation.
• As much as possible, reduce the length and curvature of the drain line. Always allow an
air gap between the drain line and the wastewater to prevent the possibility of wastewater
being back-siphoned into the carbon filter. No valve of any type should be installed along
the drain line.
