Faq; Troubleshooting - Delta UV E Série Guide D'installation

G. FAQ:
Here are a number of FAQ's that will answer some of the most common questions.
Is the Delta UV (DELTA UV) System Designed For Salt Water Use?
While the ability of the system is not affected by salt water, the harsh environment found in salt water ponds and aquariums is not
recommended for the ES Series units due to the stainless steel inner wrapper. However, the all plastic E-Series units are compatible with
salt water environments
Will A Time Clock On My Pool Shorten My Bulb Life?
Some shortening of the bulb life can be expected when the DELTA UV unit is turned off and back on frequently. A daily on/off cycle will
not create a major bulb life issue however, frequent on/off cycles should be avoided.
Is There Any Residual Effect From UV?
No, UV light is used as a control and is applied only to the water that passes inside the DELTA UV wet chamber in visual contact with the
UV transmission from the UV bulb.
Can The DELTA UV Unit Be Mounted Horizontally?
No, vertical mounting is required to maintain the weatherproof integrity of the electrical enclosure bonnet.
Can The DELTA UV Unit Be Installed Below The Pond or Pool Waterline?
Yes.
Can Multiple Units Be Used Together For Larger Systems?
Yes, you can add any number of units to a plumbing bypass manifold system to allow for larger outputs and flow rates beyond the
capacity of a single E-40 or ES-40 unit. Delta UV also manufactures a large capacity system, the EM/MP Series. Contact BIO-UV or your
supplier for information on the EM/MP Series product line, or to obtain a drawing showing the proper method of plumbing multiple units
for larger applications.
H. 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 filtration timer, 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. Reconnect back to filtration timer ONLY after the electrical enclosure bonnet has been re-installed on the unit.
b. Verify that the filtration timer has power. Test the filtration timer. You should confirm that the power is the same as indicated
on the electrical label on your Delta UV 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. (Not warranted)
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 BIO-UV for assistance in obtaining a new ballast.
c. Verify that the electrical outlet where the DELTA UV unit is plugged into has the proper voltage and the cord is securely
connected to the filtration timer.
The Water Is Green - Green water is an indication that the UV rays generated by the DELTA UV 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 DELTA UV unit to
function fully.
c. Clean the quartz tube.
d. Replace the UV bulb if it is nearing the 13 000 hour useful life. At 13 000 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.
e. If your DELTA 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 manufacturers specifications.
The DELTA UV Unit Makes Noise When Operating - This is an indication of the DELTA UV unit not being properly attached to a firm
mounting base of wood or concrete with the bolts placed through the mounting holes in the DELTA UV unit base. It can also indicate that
the UV bulb was installed without the required bulb cushion and/or bulb O'Rings. Attach the DELTA UV 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. 9.0.
Water Is Coming Out Of Electrical Enclosure - Water exiting the unit through the electrical enclosure bonnet can be attributed to either
(a) a bad quartz tube seal, or (b) a broken or cracked quartz tube. Check the quartz tube seal and quartz tube as instructed in Sec. 7.0
and Sec. 8.0.
