b. 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 EUV unit.
c. 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 EUV unit.
d. 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. (Not warranted)
18.2 The UV Bulb 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.
b. The ballast has burned out. Contact your supplier or Delta UV for assistance in obtaining a new
ballast.
c. Verify that the electrical outlet where the EUV unit is plugged into has the proper voltage and
the cord is securely plugged into the outlet.
d. 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 EUV unit itself.
18.3 The UV Bulb Stays Lit When The Pump Is Off -
The EUV unit is equipped with a safety pressure
switch that turns the UV bulb off when the pump is turned off. This function guards against having the bulb
lit accidentally when the electrical enclosure bonnet is removed and serves to ensure that there is water
flowing in the EUV unit wet chamber to cool the bulb and extend its life.
a. If the EUV unit is located below the water level of the pond or pool, there is a static head of water
that causes pressure to be found inside the wet chamber. This static head of pressure closes
the pressure switch and the bulb stays lit even when the pump is off. Contact your supplier or
Delta UV to obtain a special pressure switch that can be adjusted to allow for the static head of
water.
b. If the EUV unit is located above the water level of the pond and the bulb stays lit when the pump
is off, replace the pressure switch.
18.4 The Water Is Green -
Green water is an indication that the UV rays generated by the EUV unit are
not effective or are not being generated by the UV bulb.
a. 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. Run your unit longer. If your unit is operating on a time clock, run the circulation pump longer
to allow the EUV unit to function fully.
c. Clean the quartz tube.
d. Replace the UV bulb if it is nearing the 9000 hour useful life. At 9000 hours of operation, the
UV bulb is 80% 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.
