0.0 Forward: The Elektra® UV Unit is designed for use in swimming pools, fountains, water features, waterfalls

and sh ponds. It is not designed for use in potable (drinking) water installations. Use of this product in

applications other than those indicated above will void your warranty and could be harmful to your health or
the health of others.

1.0 Introduction - How The Elektra® UV Unit Works: Within the Electra® UV Unit (which we will refer to throughout

this manual as EUV), a high intensity electrically operated Ultraviolet (UV) bulb is located inside the unit’s wet chamber.
This UV bulb gives off Ultraviolet light wave emissions when lit. The bulb’s operating emission range is within the
Ultraviolet light wave spectrum at 253.7 nm of wavelength. This wavelength is such that when bacteria, protozoa,

viruses, algae spores, or other single celled waterborne microorganisms in the incoming water ow are exposed to

the light waves of the UV bulb for a proper period of time, the DNA of the microorganism is altered or disrupted and
this controls and eradicates these unwanted contaminates and renders them harmless. Your EUV unit has been sized
to produce these important UV rays in the same intensity as is required for Class A potable drinking water, which is
30 microwatts/sec/cm2.

While you may see lesser competitive units of similar vessel size claiming to work on larger ponds or pools, you will

nd that these units do not operate at the same high intensity as does the EUV unit and are unable to obtain the
same level of killing power as the EUV unit. Rely on the ow chart shown herein for proper maximum killing power

unit selection for your application.

Pond or pool water containing these unwanted contaminates enters the EUV unit’s wet chamber and is exposed to

the light rays generated by the UV bulb. The EUV unit has been designed to allow for some turbidity in the water, as
turbidity will reduce the UV light wave transmission capability. Therefore, all EUV units are sized to allow for possible
turbidity in the water and the reduction in the killing power of the UV bulb when it nears the end of its useful life.

When the incoming water is exposed to the bulb for the proper duration and intensity, the water exiting the unit is near

drinking water biological quality. CAUTION!: THIS UNIT IS FOR POND OR POOL USE ONLY. DO NOT USE THIS
UNIT FOR POTABLE (DRINKING) WATER SANITIZATION.

2.0 Pre-Installation - In order to ensure that your EUV unit functions with the proper exposure time to achieve the
desired water sanitization, it is important to provide the proper water ow rate through the EUV unit. If water passes
through the unit too quickly, the exposure time of the microorganisms to the UV bulb produced rays will not be sufcient
to obtain the desired kill rate. The water ow rate through the UV unit is governed by the piping of your pool or pond

and the size and output of your circulation pump. There also needs to be consideration to the application for the UV
unit. Fish ponds have different requirements than do swimming pools, water features, fountains, or waterfalls.

2.1 Pond Turnover Rates - Most sh pond experts agree that there is no set formula for the sizing of circulation

pumps and UV systems for ponds. The size of the pond, the depth, plant coverage, the amount of sun exposure
or shade, and the number of sh in the pond all contribute to determining what the ow rate for a pond should
be. The best advise is to consult with a pond expert to determine what the ow rate for your pond should be.

This is the best method of ensuring that your pond is being circulated properly. But absent of that, a general
rule of thumb that can be used for ponds is that the water volume of the pond should be passed through the

lter system every two hours or so. Thus, if you take the volume of your pond (in gallons), and divide that by
120 (the number of minutes in two hours) you will have an approximate desired ow rate for your pond. Then,
you select a pump and lter system that works properly at that ow rate. As an example, a 6000 gallon pond
would have a desired ow rate of 50 gallons per minute (GPM) calculated at 6000 /120 = 50.

2.2 Pool Turnover Rates - Swimming pools are somewhat simpler to calculate for ow rates. Most residential

pools are designed to have the capacity of the pool turned over every 12 hours. Semi-commercial pools are

normally designed for an 8 hour turnover ow rate. Check with your local jurisdiction for the required ow rate for
your type of pool to be sure. Thus, as an example, using the same formula as above, a 20,000 gallon residential
pool will need to have a pump capable of a 28 GPM ow rate and a 25,000 gallon Semi-commercial pool will

need to have a pump capable of 52 GPM.

Like pools and ponds, the EUV unit needs to be properly sized by ow rate. Moving the water through the EUV
unit’s wet chamber too fast will not allow enough exposure time of the water to be exposed to the UV bulb rays
for the required exposure time. The following chart shows the desired and maximum ow rates for your EUV
unit. Make sure the ow rate of your circulation system pump does not exceed the maximum allowable ow rate

of the UV unit you have selected. (Consult your supplier or pump manufacturer for the pump’s GPM rating if you

5

are in doubt). If the pump output exceeds the maximum ow rate of the EUV unit you have selected, select an
EUV model with a higher ow rate capacity rating or consider a multiple unit installation. (See Sec. 17.7).

5.0 Installation

— Before starting the installation, PLEASE read this manual from cover to cover. A few moments

spent initially becoming totally familiar with the EUV unit and its installation requirements will save a great deal

of time (and expense) later. If you have questions that are not answered after you have completed the reading

of this manual, contact your supplier or Delta UV. We are ready to assist you at anytime and we want your
installation to go smoothly and the equipment to work properly.

5.1 Locating The UV Unit - Once you have conrmed the sizing of your pond or pool and compared that
information against the requirements of your EUV unit by using the charts above, it is now time to install your
unit. The EUV unit comes with all internal components fully assembled and ready for installation. Only the
Inlet/Outlet unions and pressure gauge need to be installed to ready your unit for installation. All parts of the

EUV units are UV inhibited PVC plastic. Thus, your unit will function ne in the outdoors. Installing the EUV unit

indoors or inside a covered area is preferred however, to keep your unit looking new. The EUV unit will need
to be powered from a 120 V/15A electrical outlet. If the electrical outlet is outdoors and open to the weather, it
will need to be an Outdoor type receptacle. The EUV unit comes with a eight foot power cord. Do not use an

extension cord unless it is at least a 16/3 size conductor waterproof type and is no more than twenty-ve feet

(7.5 meters) long.
Note: 240V / 50/60HZ units are available – Contact your dealer for more information.

5.2 Plumbing The UV Unit - Your EUV unit will need to be plumbed into your pond or swimming pool circulation
system. The diagram (Fig. 1) shows how the unit is to be plumbed. Note that the water is to be piped from the
pressure side of the pump and after the lter, in and out of the EUV unit. The inlet for the water is at the bottom
of the EUV unit, and the outlet is at the top of the EUV unit. If your pump exceeds the maximum ow rate of

the EUV unit, installation of a plumbing by-pass will be necessary to bypass some of the pump’s ow around
the EUV unit so the maximum ow rate of the EUV unit will not be exceeded. A typical bypass arrangement is

shown in Fig. 2
