10.3 Electrical Enclosure Bonnet Removal - Follow Sec. 7.3 instructions to remove the electrical enclosure

bonnet.

10.4 Steps To Follow For Bulb Replacement - Follow the steps noted for bulb removal and replacement

during quartz tube removal (Sec. 7.0) and installation (Sec 9.0) to remove the old bulb and complete the

installation of a new bulb.

11.0 Additional Maintenance - While not required for the function of your EP unit, you can keep your EP unit looking

new by periodically applying a light coat of car wax to the exterior of the unit at initial installation, then periodically

thereafter as required. Be careful not to damage the silver product identification label, as EP units returned for service

with missing or mutilated labels will not be warranted. No other scheduled maintenance of your EP unit is necessary.

All other components not mentioned previously do not require any preventive maintenance. Should any component be

needed, you can identify the component part number in Sec.16 of this manual and obtain it from your original supplier,

or if he does not have it, then from Delta UV directly.

12.0 Normal Operating Results - Ponds, swimming pools, fountains, waterfalls, and water features have different

disinfection and clarification needs than fishponds. The EP unit provides those needs in the same manner equally

effectively, for all types of water environments specified herein.

12.1 Normal Operating Results (Ponds) - On properly sized and installed pond installations, you can

expect to correct green water condition in 3-5 days of continuous operation after start-up. Remember, only

water that enters the EP wet chamber is exposed to the UV rays of the bulb, so algae that clings to the sides

and bottom of your pond will not be affected by installing an EP unit. This is normal and the retention of

biologicals outside the EP unit is desired for proper bio-filtration. Thus, the EP unit will not harm your bio-

filtration, fish population, or pond eco-system.

12.2 Normal Operating Results (Swimming Pools, Fountains, Water Features) - You will see a significant

improvement to your water clarity and the “chlorine odor” should disappear in 2-4 days of continual operation

after start-up on properly sized and installed pools, fountains, waterfalls and water features. Remember, as

noted before, the EP unit will dramatically reduce the pools reliance on sanitizers and algae control products.

Many users of UV units report a 70%-90% reduction in their chemical use. This is not only desired due to

reduced operating costs, but the major reduction of sanitizer levels makes for a more healthier bathing

environment. REMEMBER, you must continue to check your water chemistry regularly as required for your

water vessel, and some chemicals will still be necessary to supplement the sanitization and control capability

of the EP UV unit.

13.0 Winterizing - Your EP unit can be damaged if allowed to freeze. The substantial pressure inside the wet

chamber caused by ice forming inside the wet chamber can break the glass quartz tube, as well as the wet chamber

itself. Therefore, you must protect your EP UV unit from freezing. Damage due to freezing, including breakage of

glass components, the wet chamber, or water damage to other components caused by freezing

IS NOT COVERED

under your Limited Warranty.

13.1 Ponds - Freeze damage can be avoided by keeping the water flowing at a minimum of 5 PSI pressure (as

noted on the pressure gauge) at all times, without interruption during freezing temperatures. All time clocks

must be inoperable and the pump must run continuously. Freeze damage can also be avoided if the pump and

EP unit is maintained inside a warm enclosure.

13.2 Swimming Pools, Fountains, Water Features, Waterfalls - If you do not plan to operate your EP UV

unit during freezing temperatures, you must take precautions to make sure all water is removed from inside

the EP wet chamber so it does not freeze inside the wet chamber and damage the EP unit. This can be

accomplished by first closing any valves on lines in or water is drained from inside the wet chamber tank. A

safe precaution is to place the EP unit in a warm

location during freezing temperatures, after draining all the water from the unit and removing it from the

plumbing.

14.0 Swimming Pool Chemicals - Your EP unit does not add any chemicals to your swimming pool or pond water.

Its job is to kill bacteria, parasites, microorganisms and algae that come into contact with the UV rays inside the EP
