9.3 Insert Bulb Into Quartz Tube - Slowly lower the bulb down into the quartz tube, until the bulb O’Rings are
down inside the quartz tube. Make sure the bulb O’Rings have not become dislodged from the white ceramic
on the end of the bulb while the bulb is being inserted down into the quartz tube. Re-position the bulb O’Rings
if necessary.
9.4 Ballast and Bulb Caution - CAUTION: DO NOT INSTALL THE ELECTRICAL SOCKET FROM THE
BALLAST TO THE FOUR PINS ON THE END OF THE BULB AT THIS TIME. DOING SO NOW WILL
CAUSE THE BULB TO LIGHT WHEN THE PUMP IS TURNED ON AND EXTENDED VIEWING OF THE
LIGHT BULB CAN CAUSE BLINDNESS OR EYE INJURY. DO NOT LOOK DIRECTLY AT THE LIT BULB
AT ANY TIME.
9.5 Install Ballast Socket On Bulb - Once you have verified that the quartz tube seal is not leaking,
TURN
OFF YOUR PUMP IF YOU HAVE NOT DONE SO PREVIOUSLY. Then, WITH THE PUMP OFF, connect the
electrical socket from the ballast to the four pins on the bulb by pushing the socket down over the pins. NOTE:
The socket will only install on the bulb pins in two opposite orientations. The pins are not equally spaced in all
directions, so check the pin alignment before pushing down on the electrical socket. Once you are sure that
the socket openings mate up to the pins, you can push the socket down onto the pins. DO NOT force the
socket onto the pins. If force is needed, it means you have not aligned the pins to the socket.
9.6 Install Electrical Enclosure Bonnet - Reinstall The Electrical Enclosure Bonnet – Place the plastic
electrical bonnet on the top of the EP unit on the four stand-offs provided, and tighten the screws using a
Phillips screwdriver. Make sure the star washers on the screws are located on the outside of the electrical
enclosure bonnet. They keep the electrical enclosure bonnet securely in place. DO NOT over tighten the
screws.
9.7 Plug UV Unit Into Electrical Power - Plug The EP Unit Power Cord Into The Power Receptacle – The
bulb will not light until the pump is turned back on, due to the pressure switch remaining open until pump
pressure inside the wet chamber is sensed, verifying the water flow through the EP wet chamber.
9.8 Turn Pump Back On - Turn The Circulation Pump Back On – Verify that the bulb is lit by viewing the glow
of the bulb through the clear plastic union fitting at the outlet of your EP unit. Your EP UV unit is now ready
for service.
10.0 Scheduled UV Bulb Replacement - In addition to cleaning of the quartz tube periodically, annual replacement
of the UV bulb is required. The High Output UV bulb in your EP unit has a useful life of approximately 9000 hours of
operation, which is about one year of continual use. 9000 HOUR BULB REPLACEMENT IS MANDATORY – Even
though the bulb may be glowing after 9000 hours of operation, do not operate your EP unit longer without replacing the
bulb as the bulb will have reached its useful ability to do its job by then. Bulb replacement is best done at the same
time as quartz tube cleaning to minimize your maintenance efforts. This can be accomplished with a little planning
ahead. You should schedule one of your quartz tube cleanings to take place at the required 9000 hour bulb replacement
time occurrence.
As a point of information, it should be noted that if you start and stop your circulation pump frequently, such as by daily
time clock operation, you will cause the bulb to be more susceptible to burning out more quickly than if used continually.
This is the same phenomenon you see when you turn on a table lamp and it flashes and burns out. The momentary
inrush of billions of electrons that occurs when a bulb is first energized has a detrimental effect on the filament of all
bulbs, thus the cause for a potentially shorter bulb life.
10.1 Schedule Of Replacement - It is recommended that you mark your calendar for bulb replacement ten
or eleven months from the initial date of installation of your Elektra Pro UV unit. This will give you ample time
to obtain a new bulb from your supplier before re-lamping is required. If your application is critical, as in a Koi
pond, where you absolutely do not want to have your EP unit out of service for any period of time, it is
suggested that a spare bulb be kept on site so you can change out the bulb immediately in the future if
replacement is needed. Bulb replacement is accomplished as follows:
10.2 Disconnect Power Source - First, disconnect your EP unit from its power source by unplugging the
power cord from the electrical receptacle. This is a MUST anytime you remove the electrical enclosure bonnet
for any reason.
