Install Instructions

Installation
Before Installation
o The unit comes with two ports. Both are 1-inch MNPT and can be used as an inlet or outlet. Please choose the correct
fittings to fit your plumbing. It is recommended that you install an inlet valve and an outlet valve before and after the
unit for easy maintenance. Please make sure that it can be easily disassembled from the water line for future
maintenance.
o The unit should be installed after a sediment filter, as sediments in the water can block UV light and become a shelter
for contaminants. Thus, water coming into the UV filter must be clear (free of particles larger than 20 microns). It is
recommended that you install the UV filter after the filters as the last stage.
o If water flow speed exceeds rated flow, please install a flow-limiting or pressure-limiting device. If the water pressure
is over 43 psi, please install a pressure regulator in the inlet/outlet to protect the quartz sleeve.
o Please install the filter at a position by the retaining clip, retaining nuts, or other mounting devices to prevent it from
dropping due to the vibration caused by water and causing damages to the fragile internal parts.
o The ultraviolet water filter is not designed to eliminate bad tastes or smells, biological materials, chemicals, silt, heavy
metal, and other kinds of impurities. It does not reduce sediments that affect the efficiency of the UV lamp. Therefore,
it is necessary to install a pre-filter to ensure that the filter can achieve optimal performance.
Installation Steps
Step1– Before mounting the two black plastic clips onto the wall, make sure there is enough room for stainless-steel housing
and access for future servicing. It can be installed horizontally or vertically. (If you choose vertical mounting, make sure that the
water inlet is mounted at a lower level while the outlet is at a higher level to slow down water flow and increase exposure to
the UV light.
