Troubleshooting - Delta UV ELECTRA UV EA Serie Instrucciones De Montaje Y Mantenimiento

I. TROUBLESHOOTING
The list below will help guide you through any problems you may have at time of initial installation or in
the future. For additional assistance, contact your supplier or BIO-UV at the address, e-mail or phone
shown at the end of this manual.
The UV Bulb Will Not Light - If this occurs upon initial start-up, the problem could be caused by a
number of issues.
a. The bulb has become disconnected from the bulb connector - Disconnect the power cord
from the electrical outlet, open the electrical enclosure bonnet and confirm the bulb connector is
firmly in place. At the same time, check all exposed wires for a possible loose connection. Plug
the electrical cord back into the electrical outlet ONLY after the electrical enclosure bonnet has
been re-installed on the EA unit, and the pump is ON.
b. Verify that the electrical cord is plugged into a hot outlet - Test the electrical outlet. You
should confirm the availability of the same power as indicted on the electrical label on your EA
unit.
c. Make sure you have not plugged your unit into any power source other than that specified
on your unit's electrical label - If you have done so in error, the ballast has been damaged and
needs to be replaced. Contact your supplier for the correct replacement ballast.
The UV Bulb Was Lit But Now Is No Longer Lit - This occurs after the unit has been operating
successfully for a period of time.
a. The bulb has burned out. - Replace the UV bulb. Contact your supplier or Delta UV to obtain a
replacement bulb for your EA unit.
b. The ballast has burned out. - Contact your supplier or Delta UV for assistance in obtaining a
new power cord/ballast assembly.
c. There is no power to the outlet - Verify that the electrical outlet where the EA unit is plugged
into has the proper voltage and the EA unit's power cord is securely plugged into the outlet.
d. The GFCI has tripped - Verify that the GFCI has not tripped. To verify the operating state of the
GFCI, trip the GFCI manually and reset it manually. The GFCI should reset. If it does not, it
indicates a fault to ground in the electrical circuit or the EA unit itself. See Sec. 18.5 for more
details on GFCI issues.
The UV Bulb Stays Lit When The Pump Is Off - The UV bulb should not be lit when there is no water
running through the EA unit's wet chamber. This condition will cause the bulb to burn out very quickly
due to the heat generated by the UV bulb inside the quartz tube when no water is flowing to carry off the
heat.
a. Time clock interlock missing - If a time clock is used, it should be electrically interlocked to the
electrical outlet servicing the EA unit, so the power to the outlet is interrupted whenever the clock
turns the pump OFF. If this condition is present, refrain from using the EA unit until an electrical
interlock is installed.
b. EA unit not unplugged when pump is OFF - If no electrical interlock to the pump is present,
the electricity to the EA unit must be halted by unplugging the electrical power cord from the wall
receptacle before turning OFF the pump. To eliminate this necessity, electrically interlock the EA
unit poser receptacle to the pump.
The Water Is Green - Green water is an indication that the UV rays generated by the EA unit are not
sufficiently powerful to be effective or are not being generated at all by the UV bulb (bulb at end-of-life).
a. Bulb not lit - Check the bulb to make sure it is ON. If it is not ON, follow the procedures above
regarding the UV bulb not lighting.
b. EA unit not operating long enough - Run your unit longer. If your unit is operating on a time
clock, run the circulation pump longer to allow the EA unit to function fully. It is especially
important to allow the unit to run continuously at initial startup.
c. Quartz tube dirty - Clean the quartz tube.
