G. FAQ
Here are a number of FAQ's that will answer some of the most common questions.
Is the Elektra® UV (EUV) 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
Do I Need To Turn My EUV Unit Off When I Clean My Filter?
No, the flow sensing pressure switch that is part of your EUV unit will automatically shut the UV bulb off
until proper water flow inside the EUV unit is re-established. Should you need to turn your unit off for any
reason, this is accomplished by simply unplugging the EUV unit from its power outlet.
Will A Time Clock On My Pool Shorten My Bulb Life?
Some shortening of the bulb life can be expected when the EUV 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 EUV wet
chamber in visual contact with the UV transmission from the UV bulb.
Can The EUV Unit Be Mounted Horizontally?
No, vertical mounting is required to maintain the weatherproof integrity of the electrical enclosure bonnet.
Can The EUV Unit Be Installed Below The Pond or Pool Waterline?
The EUV unit has a pressure switch that controls the on/off cycle of the UV bulb when the pump stops or
starts. If the EUV unit is installed (example, in a vault below the waterline of the pond or pool), a static
head of water pressure may be sufficient to cause the pressure switch to remain closed, which means
that the UV bulb will remain lit at all times while the EUV unit is plugged into its power source. Contact
BIO-UV or your supplier for a different type of pressure switch (Part # 70-02301) that can be adjusted to
allow for this static water pressure in the EUV wet chamber. Installation of this type of pressure switch
takes only a few minutes and will restore the desired ability of the bulb to be turned off automatically
when pumping is interrupted. DO NOT OPERATE YOUR UNIT WITHOUT A PROPERLY WORKING
PRESSURE SWITCH.
Can Multiple Units Be Used Together For Larger Systems?
Yes, you can add any number of EUV 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 Elektra® Max UV system, that incorporates factory installed hydraulically
balanced piping and multiple tanks contained within a metal enclosure. The Elektra Max system features
the latest technology in high output UV bulbs, dubbed Amalgam bulbs. Contact BIO-UV or your supplier
for information on the Elektra Max product line, or to obtain a drawing showing the proper method of
plumbing multiple EUV units for larger applications.
Must I Use A GFCI (Ground Fault Circuit Interrupter) With My UV Unit?
YES.
