5.6 Gluing Piping To The UV Unit - The Inlet/Outlet PVC union tail pieces are 2 inch pipe size (63mm for

overseas models). Your PVC supply piping should be glued into the union tail pieces using an appropriate

PVC primer and PVC cement, as recommended by your supplier. Inlet piping should be supported and

should not rest solely upon the unions, to avoid breaking the unions. The installation of valves on the inlet and

outlet lines attached to the UV unit is recommended. If the EP unit is located with any portion of the unit

below the surface of the pond or pool, then VALVES ARE MANDATORY ,so you may winterize or remove the

EP unit without draining your pool or pond. When you have completed the piping installation (including

bypass if necessary), the final step is to plug in the unit to its power source.

5.7 Electrical Connection - The electrical power rating for your EP unit is shown on the label on the outside

of the unit. US and Canadian EP units operate on 120 V/50/60 Hz – (1.15 Amps maximum). This low power

consumption makes operating your EP unit very economical. Therefore, you will need a 15Amp 120V

receptacle for your EP unit to plug into. (Check the label on your overseas unit for its power requirement).

Your EP unit is supplied with an eight foot long weatherproof power cord terminating in either a 3-prong

grounded NEMA plug, or in an optional cord connected Ground Fault Circuit Interrupter (GFCI). Whether you

use the factory installed GFCI or install a GFCI in the electrical outlet or in the breaker panel serving the EP

unit power receptacle, you will need to have the unit GFCI protected. Note: Should the electrical power cord

of your EP unit become frayed or damaged in the future, unplug it from the power receptacle and replace it

immediately.

If you did not order your EP unit with the cord connected GFCI installed, you may add it in the field. You will

need to order Part # 70-09012 (Retrofit Cord Connected GFCI Kit) from the supplier of your EP unit. This kit

comes complete with everything you need to install the weatherproof GFCI on the end of the EP unit power

cord. Easy to follow installation instructions are included with the kit and should take only a few minutes to

complete. Verify that you have power to your electrical outlet and then plug the EP unit power cord into your

power outlet.

5.8 Electrical Bonding (Grounding) - As required by Article 680, NEC and many local electrical codes, all

metallic equipment of your pond or swimming pool system must be electrically bonded to a common bonding

grid, using a continuous #8 bare copper wire to connect all components (pump, filter, EP unit) together using

the ground lugs supplied with each component. The EP unit has a copper grounding lug located on one leg

of the mounting base for this function. Connect the bonding wire from the bonding grid to the grounding lug

supplied on the EP unit. The electrical installation is now complete.

DANGER - RISK OF ELECTRICAL SHOCK - RISK OF

INJURY OR DEATH IF ELECTRICAL INSTALLATION

AND BONDING ARE NOT DONE PROPERLY.

If you are in doubt, have this important work

done by a Licensed Electrician!

5.9 Safety Pressure Switch - The EP UV unit is equipped with a safety pressure switch that does not allow

the UV bulb inside the unit to light unless there is at least 5 PSI operating pressure inside the chamber. This

is to ensure that the bulb will not create heat when the EP unit is empty or water is not flowing in the wet

chamber. Such excessive heat can shorten the life of the UV bulb. Therefore, only when the pump is pumping

water through the EP unit wet chamber will you be able to see the UV bulb glow and confirm that it is on.

Note: Low pressure 1/2 psi pressure switches are available if you have a low pressure piping system (Found

most frequently in Koi pump installations). Order P/N 70-02315. Without the circulation pump operating, you

will not see the bulb light up just by plugging the unit into its electrical outlet. Once the pump is pumping

water thought the EP unit, as confirmed by the indication of pressure on the pressure gauge, the bulb will

light. To confirm that the bulb is indeed lit, you can view the glow of the bulb through the clear plastic union tail

piece at the top outlet of the EP unit. This is the only location where you should attempt to view the UV bulb

while it is on. The PVC union tail piece screens out the harmful UV rays and can be viewed with the naked eye

without any damage to the eyes. If the bulb is not lit, check the troubleshooting section at the end of this

manual.
