THE UV LAMP(S) IS/ARE NO LONGER ON
If this occurs after the unit has been operating successfully for a period of time.
1. One or more lamps have burned out. Replace the UV lamp(s).
2. A ballast has burned out. Contact your supplier or Paramount for assistance in obtaining a new ballast.
3. Verify that the electrical outlet where the Ultra UV2 unit is plugged into has the proper voltage and the
cord is securely plugged into the outlet or connected to the power source.
4. Verify that the GFCI has not tripped. To verify the operating state of the GFCI, trip the GFCI manuall
y
and reset it manually. The GFCI should reset. If it does not, it indicates a fault to ground in the electrica
l
circuit or the Ultra UV2 unit itself. Contact your supplier for assistance
.
5. The ballasts have internal protection that will power down the lamps in the case of an electrical event
.
Power down the unit for 5 minutes. This will reset the internal protection. When the power is returned
,
the internal protection is reset.
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).
a. 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. If all lamps are not ON, follow the procedures abov
e
regarding the UV lamp not lighting.
b. Run your unit longer. If your unit is operating on a time clock, run the circulation pump longer to allow
the Ultra UV2 unit to function fully.
c. Clean the quartz tube(s).
d. Replace the UV lamp(s) nearing the 13,000 hour useful lamp life. After 13,000 hours of operation, the
UV lamp(s) are only 80% as effective as when new. This is normal for all long life low-pressure type U
V
lamps, which are the longest useful life lamps available for this type of application.
e. If your Ultra UV2 unit is installed on a swimming pool, shock the pool with the sanitizing chemical you
normally use and balance the pool water as per your chemical manufacturer’s specifications.
f. Your unit is not sized for the flow and duration specific to your pool.
THE GFCI HAS TRIPPED
If you have installed a GFCI on your Ultra UV2 application, the GFCI will protect the Ultra UV2 unit and
any other equipment on the same electrical circuit from any fault to ground, the same as the electrical
breaker protects the total electrical circuit from a short. When the GFCI trips, it is an indication that
there is an electrical problem that must be corrected to provide a safe operating environment for your
installation. Follow the instructions of the GFCI manufacturer for more information on correcting the issue
if the problem is with the GFCI.
a. If you suspect that the problem is with the Ultra UV2 unit, disconnect the Ultra UV2 unit from the
electrical receptacle. Reset the GFCI at the breaker panel or at the receptacle. If the GFCI doe
s
not reset, have the G.F.C.I replaced by a licensed electrician. If the GFCI does reset, first run the
circulation pump, and if no GFCI trip is encountered, plug the Ultra UV2 unit into the electrica
l
receptacle and make sure the pump is ON. If the GFCI trips, it is an indication that there is a groun
d
fault inside the Ultra UV2 unit. Follow the instructions previously given for opening the electrical
enclosure cover and inspecting the Ultra UV2 unit. Call a qualified technician
.
b. If water is present inside the electrical enclosure cover, it will trip the GFCI. Following instructions
given previously to remove the quartz tube(s), inspect for quartz tube cracks or breakage or for a ba
d
quartz tube seal. Replace the quartz tube if it is cracked or broken. If not reseal it. See page 6.
c. If the Ultra UV2 unit trips when performing the test noted in Sec. (a) above, you can check to
determine if a UV lamp is the GFCI trip cause by unplugging the individual lamp from the lam
p
connector, then place the electrical enclosure cover back on the Ultra UV2 unit and power up th
e
circulation pump. If the GFCI does not reset, then the problem is either with the remaining lamp(s
)
or with a ballast. Remove all the lamp connectors and reset the GFCI after replacing the electrica
l
enclosure. If the GFCI still trips, unplug all ballasts. If the GFCI resets, then plug in first one ballast
,
and if your unit has two ballasts, then the second ballast after the first ballast has been tested. If either
ballast trips the GFCI, then replace that ballast. Refer to page
19 for the proper ballast part number.
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. Replace the UV lamp.
