H. FAQ
Here are a number of FAQ's that will answer some of the most common questions.
Is the 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 EA UV units due to the stainless steel construction. Contact your
supplier or Delta UV if you have a salt water system and they will supply you with information on the DELTA
UV system which is totally compatible with salt water environments. Salt chlorine generators however are
compatible with all Delta UV systems, as they operate in a minimum salt level environment. Sea water is not
compatible.
Do I Need To Turn My EA Unit Off When I Clean My Filter?
Yes. Anytime the water flow is interrupted to the EA unit, the power to the unit should be turned off at a
switch or breaker controlling the receptacle that supplies power to the EA unit, BEFORE the water flow is
interrupted. If no switch or breaker is convenient, you can accomplish this by simply unplugging the EA unit
from it power outlet.
Will A Time Clock On My Pool Shorten My Bulb Life?
Some shortening of the bulb life can be expected when the EA 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 EA wet chamber in
visual contact with the UV transmission from the UV bulb. No chemical change to your pool, spa or pond
water takes place.
Can the EA Unit be Mounted Horizontally?
Yes, the EA unit can be installed in any position. When mounting the unit, make sure that the water outlet is
placed higher than the inlet, so the unit will not drain and allow the quartz tube to operated dry. This will
ensure that the quartz tube remains submerged at all times. When mounting the unit horizontally, either
union can be used for inlet or outlet.
Can the EA Unit be Installed Below the Pond, Spa or Pool Waterline?
The EA unit can be installed below the waterline. Consideration should be given for future winterizing and
servicing of the EA unit. The use of valves on both sides of the UV unit are a must to isolate the EA from the
pool or pond water. NOTE: DO NOT INSTALL ANY EA SERIES UNIT BY IMMERSING IT IN THE VESSEL
WATER. All EA Series units are suitable for outdoor installation, but are not suitable for immersion in the
water. SERIOUS DAMAGE WILL OCCUR TO THE EA UNIT IF SUBMERSED, AS WELL AS RISK OF
ELECTRICAL SHOCK. Submersion of the unit will void your Limited Warranty.
Can Multiple Units Be Used Together For Larger Systems?
Yes, you can add any number of EA units to a plumbing bypass manifold system to allow for larger outputs
and flow rates beyond the capacity of a single EA-4H-40 unit. Delta UV also manufactures the Delta E, Delta
ES, Delta EP and Delta EM & ELP series of UV systems for larger capacity ponds and pools. If you need to
utilize more than two EA systems to meet your larger pond or pool's requirements, you will find it more
economical to select one of the other quality Delta UV systems that are available. Contact your supplier or
Delta UV for complete information and pricing of these larger capacities UV units.
Must I Use a GFCI (Ground Fault Circuit Interrupter) with My UV Unit?
YES.
