Delta UV EA Serie Installations- Und Wartungshandbuch Seite 30

d. Bulb at end of life (EOL) - Replace the UV bulb if it is nearing the one (1) year useful life. At one
year of operation, the UV bulb is 60% as effective as it was when it was new. This is normal for all
low-pressure type UV bulbs, which are the longest life bulbs used in this type of application.
e. Pool Chemistry Is Off - If your EA 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
manufacturers specifications.
f. Pump Flow Exceeds Unit Design Capacity - Your unit is undersized if the water is not clearing up
on a new installation. Check the flow rate of the pump and compare it to the maximum flow rate for
your unit (available online at www.deltauv.com). Flow rates in excess of the maximum flow rate of
your UV unit will render the system ineffective as there is not sufficient exposure time of bacterium to
the lamp rays. Replace with a properly sized system for your flow rate and the water will clear up.
The GFCI Has Tripped - The GFCI protects the system from any fault to ground, as the electrical breaker
protects the electrical circuit. When it trips, it is an indication that there is an electrical problem that must be
corrected to provide a safe operating environment in your pool or pond.
a. Test the GFCI - Disconnect the EA unit from the electrical receptacle. Reset the GFCI at the breaker
panel or at the receptacle. If the GFCI does not reset, replace the GFCI. If the GFCI does reset, plug
the EA 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 EA unit. Follow instructions previously given for
replacing the bulb.
b. Inspect the EA unit's electrical assembly - If water is present inside the electrical enclosure or
quartz tube, it will trip the GFCI. Following instructions given previously, remove the quartz tube,
inspect it for cracks or breakage or for a bad quartz tube seal. Replace the quartz tube if it is
cracked.
c. UV Bulb is causing GFCI tripping - You can check the UV bulb for GFCI trip cause by unplugging
the bulb from the bulb connector, then plugging the electrical plug back into the electrified electrical
outlet (make sure the outlet is powered). Reset the GFCI and if it does not trip, it indicates that the
UV bulb is causing the fault to ground. Replace the UV bulb. If the GFCI does not reset, then the
problem is with the ballast or the electrical power cord. Replace the ballast/cord assembly.
The EA Unit Makes Noise When Operating - This is an indication of the EA unit not being properly
attached to a firm mounting base of wood or concrete with the mounting stands and band clamps provided. It
can also indicate that the UV bulb was installed without the required bulb cushion and/or bulb O-Rings.
Attach the EA unit correctly to a firm base as described in Sec. 5.5, or install the bulb cushion and/or bulb O-
Rings as described in Sec. 9.1.
Water Is Coming Out Of Electrical Enclosure - Water exiting the unit through the electrical enclosure
assembly can be attributed to either (a) a bad quartz tube seal (Factory installed), or (b) a broken or cracked
quartz tube. Check the quartz tube for cracks or breakage as instructed in Sec. 7.0 and Sec. 8.0. Replace
the quartz tube assembly if cracks in the quartz tube are found upon inspection.
