The UVF11 series come with a flow sensor that turns the UV on and off automatically with
water flow. It automatically turns off when the flow sensor detects there is no water flowing
through the unit. This special design reduces energy consumption and prolongs the life span
of the UV lamp.
The UVF11 series are capable of self-cleaning. Suppose the unit has been idled for 24 hours
but still has power on. In that case, it will start the self-cleaning process by turning itself on
for 300 seconds to ensure that water in the reactor chamber will not deteriorate.
The UVF11 series work as follows:
a. Water enters the UVF11 series and flows into the annular space between the quartz
tube and the inner wall of the stainless steel reactor chamber.
b. The UV lamp emits UV rays to start the purification process. The green LED indicator on
the electronic ballast will immediately light up, indicating that the UV lamp is in
operation and working properly. There is no dead corner in the chamber for water
without being purified.
c. Water that leaves the UVF11 series is ready for use; no further contact time is required.
d. When the UVF11 series are not functioning properly, the red LED indicator starts
flashing, and the alarm sounds off.
e. When there is no water flowing through the UVF11 series, the unit will be in standby
mode, and all the indicator lights will be off.

Precautions
Warning:
- Changes or modifications made to this system without the manufacturer's consent could
render the system unsafe for operation and may void the manufacturer's warranty.
- Do not operate the UV Lamp when removed from the reactor chamber, as this may cause
exposure to dangerous UV radiation.
•To avoid possible electric shock, special care should be taken since water is near the
electrical equipment.
•Do not operate the unit if it has a damaged cord or plug, malfunctioning, or has been
dropped or damaged in any manner.
•This unit is only designed for potable water applications. Using attachments not
recommended or sold by the manufacturer may cause unsafe conditions.
•Please do not install this product outside or at a place where it is exposed to direct
sunlight or freezing temperature.
•Please install this product at a place where it is easy to access and maintain.
•The UV lamp contains mercury. If the lamp breaks, avoid inhalation or ingestion the
debris and avoid exposure to eyes and skin. Never use a vacuum cleaner to clean up a
broken lamp, which may scatter the spilled mercury. Follow local regulations and
guidelines for the removal and disposal of mercury waste.
Installation
Note:
•Make sure the quartz tube and UV Lamp are clean before installation. Use alcohol or
mild detergent to clean if necessary.
•The UVF11 series are designed for continuous operation. Frequent switching will reduce
the UV radiation and service life.
•Always turn the main power off before any actions on the UV system.
•The UV system should be installed after the filters as the last stage.
•Keep the UV system away from children to avoid potential injury.
Step 1. Remove both the open end nut and closed-end nut from the reactor chamber.

Step 10. Carefully insert the UV lamp and the blue cable all the way down into the reactor
chamber. Install the black cover cap attached to the ballast onto the open end nut.
Step 11. Install the elbow fittings onto the water inlet and outlet of the reactor chamber: 1)
remove one clip from each of the fittings; 2) push the end of the fitting all the way down into
the reactor chamber; and 3) re-
install the blue clips onto the fittings to secure the
connections. Be sure to push the clips all the way down.
Step 12. Install 1/4'' tubings (not included) onto both elbow fittings: 1) remove clips from the
fittings; 2) push tubing all the way (about half an inch) into the fittings; 3) re-install the clips
onto the fittings to secure the connections by pushing them all the way down.

Maintenance and Inspection
For your safety, always wear eyewear and turn the power off before servicing the unit.
Servicing the unit with the power on will also cause damage to the ballast.
A. Clean the UV Lamp and the Quartz Tube
Clean the UV lamp and quartz tube at least three times a year if the unit can be dismounted
easily. Otherwise, please replace the lamp and quartz tube every 1-2 years.
Follow the steps below to clean the lamp and the quartz tube. Use great care when handling
the quartz tube as it is very fragile; avoid bumping or jarring it.
a. Wear appropriate gloves to avoid contaminating the lamp.
b. Unplug the power, shut off both inlet and outlet valves, and remove the entire unit
from the waterline.
c. Drain the water, remove the black rubber cap with the attached power cord, and
remove the lamp from the quartz tube.
d. Wipe the lamp with a piece of lint-free cloth moistened with white vinegar.
e. Pour vinegar into the water inlet and soak the quartz tube until it is clear. Rinse
thoroughly.
B. Maintain the UV Lamp
•Regularly inspect the UVF11 unit to ensure that the UV lamp is still in operation. An LED
indicator light, located on the ballast, visually indicates UV lamp operation. This indicates
lamp operation and does not indicate the level of UV intensity or transmission through
the water. Ballasts have a built-in audio alarm which will indicate lamp failure.
•To ensure the proper operation of the UVF11 unit, regular biological testing of your
water (e.g., quarterly) by an accredited agency is highly recommended. Additional
testing may be performed whenever modifications, change, or additions are made to the
plumbing system, pumps, well source water, etc., to ensure adequate purification under
new conditions.
•Other maintenance measures may include ensuring that grounding wires are secure,
replacing any damaged or broken components.
