Water leaks out from the circular light at the middle of the unit. Could this be do to a faulty o ring at the top of the inner glass tube?

Yes, a faulty O-ring at the top of the inner quartz tube could cause water to leak, which may lead to water entering the electrical enclosure and tripping the GFCI on the Ultra UV2 unit.

- Do not use this unit for potable (drinking) water sanitation. Ultra UV2 System Sizing In order to ensure that your Ultra UV2 unit functions with the proper water exposure time to achieve the desired water sanitation, it is important to provide the proper water flow rate through the Ultra UV2 unit.
Header size should be 2½" or 3" and split to two 2" pipe headers at the inlet and outlet connections. Installation NOTICE - The first step in starting your installation is to inspect the Ultra UV2 unit for damage, paying close attention to the quartz tube. Locating the Ultra UV2 Unit Your unit can be installed indoors or outdoors.
A minimum of 24 hours is recommended. Maximum test pressure for the Ultra UV2 is 50 PSI / 3.45 BAR as noted on the silver label on the unit. If local codes require the pressure test to be higher than the max operating pressure on the silver label, use the...

(if the unit is plumbed with a bypass) to ensure that the Ultra UV2 is at or below the max operating pressure. A. Plumbing the Ultra UV2 Unit with Optional Bypass Valve Installing a bypass is not recommended and should only be considered: To allow for removal of the UV unit for winterization, servicing, repairs, or replacement, while still allowing water to flow through the system.

(GFCI). The electrical power rating for your Ultra UV2 unit is shown on the silver label located on the outside of the unit (shown in the image on page 4). Make sure the supplied power meets the electrical re- quirements.
Hard Wired 120/230V 50/60Hz Ultra UV2 Units Fig. 1 NOTICE - Have this work done by a licensed Bonding Lug electrical technician. Install the conduit into the seal-tight connector. Lift the grommet from the mounting plate and feed the black, white, and green wires (Fig. 2).
The Ultra UV2 unit is equipped with pressure a switch that does not allow the UV lamp(s) inside the unit to light unless there is at least 2 PSI (0.137 BAR) inside the Ultra UV2 reactor chamber. This will ensure that the lamp(s) will illuminate when the Ultra UV2 unit has water flowing through the reactor.
Configuration for Ultra UV2 units installed with bypass. Bypass operation is used for winterization or servicing the Ultra UV2 unit. The bypass valve #1 should be fully open and the inlet valve #2 and the outlet valve #3 should be completely closed.
Winterization of Your Ultra UV2 Unit If you are in a sub freezing climate, you must winter- ize the Ultra UV2 using either option #1 or #2. Failure to do so will cause damage to the unit, which is not covered under the warranty.
- The quartz tube requires cleaning every 6 months to ensure optimum performance. Turn off all power to the Ultra UV2 unit and all other pool equipment. Unplug the unit from its power recep- tacle or turn OFF the circuit breaker that is the Ultra UV2’s power source.

½ turn. Fig. 17 12. Turn power on to the Ultra UV2 unit. Turn pump on to check for leaks. Confirm that there are no leaks, then turn off pump and power off to the unit. Reinstall lamps, spring clip and connect to ballast(s).
2½ years of operation, they have reached the end of their useful life. Turn off all power to the Ultra UV2 unit and all other pool equipment. Unplug the unit from its power receptacle or turn OFF the circuit breaker that is the Ultra UV2’s power source.
FAQs Is the Ultra UV2 unit designed for use in salt water applications? Yes. Paramount’s Ultra UV2 units are fully compatible with all salt water environments. The quartz tube could require more frequent cleaning in a salt water environment. Do I need to turn my Ultra UV2 unit off when I backwash my filter? No.
Make sure the system filter and all debris baskets are clean. Verify that the Ultra UV2 unit is operating at a minimum of 2psi, which is required to acti- vate the pressure switch. Please note that the filter gauge does not indicate the pressure in the UV unit.

The Water is Green Green water is an indication that the UV rays generated by the Ultra UV2 unit are not effective or are not being generated by the UV lamp(s). Check the lamp(s) to make sure all lamps in your system are ON (by viewing the lamp(s) through the clear viewing band on the center of the reactor.
Reset the GFCI and if it does not trip, attach the electrical plug to a UV lamp (one at a time if multiple lamps are present in your Ultra UV2 unit). If it trips with the lamp lit, it indicates that a UV lamp is causing the fault to ground.
