9.3
Connecting Bulb Pins To Bulb Connector -
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.
Reposition the bulb O’Rings if necessary.
9.4 Inserting Bulb Into Quartz Tube -
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
Making Electrical Connection To 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
Reinstall The Electrical Enclosure Bonnet -
Place the plastic electrical bonnet on the top of the
EUV unit on the four brackets provided, and tighten the screws using a Phillips screwdriver. DO NOT over
tighten the screws.
9.7 Plug The EUV 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 EUV wet chamber.
9.8 Providing Power To EA Unit -
Turn the circulation pump on and verify that the bulb is lit by viewing
the glow of the bulb through the clear plastic union fitting at the outlet of your EUV unit. Your EUV 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 EUV 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 EUV
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
Annual Reminder -
It is recommended that you mark your calendar for bulb replacement ten or
eleven months from the initial date of installation of your Elektra 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 EUV 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 The Power Cord -
First, disconnect your EUV 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.
