Troubleshooting - Delta UV EA Serie Installations- Und Wartungshandbuch

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.
