2. Before the lamp is installed, the chamber and surrounding plumbing must be free from water or
leaks.
3. Insert the UV lamp into the quartz thimble through the open end. Leave the 4 pins of the lamp
exposed to allow connection to the ballast.
a. For vertical installation, you will need to connect the power supply first before lowering the
tube into the chamber. Do NOT drop the tube as this will cause the thimble to crack.
4. Firmly holding the white cap of the UV lamp, and the Black connection of the Ballast, push the
power supply connection onto the UV lamp pins, there is a long and short side of the pins so they
will only go into the power supply 1 way. Ensure that this is connected firmly so there is a good
connection.
a. At this point the lamp should be tested briefly to ensure it is in working order and the
connection is sound.
b. Keep your hands clear of the system and turn on the power for 5 seconds to allow the lamp
to fire. Do not look directly at the lamp without eye protection.
c. Confirm that the lamp lights up correctly, and the ballast is showing a green light to signify
that the lamp is running correctly.
d. Turn off the power.
5. Slide the lamp the remaining way into the chamber, pushing the rubber sleeve over the knurled nut.
NOTE: The rubber sleeve is not a waterproof seal and is not designed to seal the water in the
chamber, it is only to hold the lamp in place and protect from slight splashing water – this
does not make the chamber IP rated as waterproof.
6. Connect the earth wire to the lug on the bottom of the UV chamber as shown above.
7. Plug the ballast into a certified single socket surge protector, then into a 240V 10A GPO
8. Turn on the power supply to start the lamp.
a. If there is a green light, everything is running correctly
b. If there is a red flashing light with an audible alarm sounding, the ballast is indicating that
there is a problem with the lamp. This may be due to a faulty lamp, or the connection was
not sound during installation. Or there may possibly be a water leak that is shorting out the
lamp.
c. Fix the issue if possible or contact the supplier for further information.
