b. If the ULTRA UV unit is located above the water level of the pool or pond and
the lamp(s) stay(s) lit when the pump is OFF, replace the pressure switch.
THE WATER IS gREEN
Green water is an indication that the UV rays generated by the ULTRA UV
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 above 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 UV 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 UV lamps, which
are the longest useful life lamps available for this type of application.
e. If your ULTRA UV 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 UV application, the GFCI will
protect the ULTRA UV 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 UV unit, disconnect
the ULTRA UV unit from the electrical receptacle. Reset the GFCI at the
breaker panel or at the receptacle. If the GFCI does 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 UV unit into the electrical receptacle and make sure the pump
is ON. If the GFCI trips, it is an indication that there is a ground fault
inside the ULTRA UV unit. Follow the instructions previously given for
opening the electrical enclosure cover and inspecting the ULTRA UV
unit. Call a qualified technician.
