Specifications

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).

3.0 Desired UV Unit Flow Rates Swimming Pools, Fountains, Water Features

Note: Multiple EA units can be used for ow rates beyond those specied herein. (See Sec. 17.7)

4.0 Desired UV Unit Flow Rates Ponds

Note: Multiple EUV units can be used for ow rates beyond those specied herein. (See Sec. 17.7) – Do not exceed

8 ft./sec. ow rate for your piping.

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
