7.6 Remove The Quartz Tube -
First make sure the quartz tube is cool. Do not handle a quartz tube until
it cools. Grasp the quartz tube that is extended above the mounting gland and pull straight up to remove
it from the EUV unit wet chamber. The quartz tube can now be easily cleaned.
7.7 Cleaning The Quartz Tube -
The quartz tube exterior can normally be cleaned by mixing a mild
solution of Muriatic Acid (available at all pool supply stores) with water in a ratio of four parts water to
one part acid. CAUTION: Follow the directions for use and handling of Muriatic Acid on the acid bottle
label, being careful to protect your eyes, wear rubber gloves, and avoid breathing fumes. DO NOT USE
ABRASIVE CLEANERS as they can scratch the high quality quartz glass.
If lime or hard water calcium
deposits are encountered, lime removal products that are available in grocery stores can be used. These
products will not harm the hard glass surface of the quartz tube. Complete the cleaning of the quartz tube,
wash it off and wipe it dry. Also, make sure the inside of the tube is dry before placing the UV bulb back
inside the quartz tube.
Lastly, carefully inspect the cleaned quartz tube for cracks. If any cracks in the quartz tube are found,
the tube should be replaced. Broken quartz tubes will allow water to enter the dry electrical chamber
and attack the electrical components of the unit, which will cause them to fail and need to be replaced.
BROKEN QUARTZ TUBES, OR WATER DAMAGE CAUSED BY BROKEN QUARTZ TUBES, ARE NOT
COVERED UNDER YOUR LIMITED WARRANTY.
8.0 Reinstalling The Quartz Tube
– The process of reinstalling the quartz tube is just the reverse of the removal
process.
8.1 Electrical Connector Assembly Removal -
Insert the quartz tube into the wet chamber by carefully
inserting it into the threaded quartz tube sealing gland.
8.2
Removing The UV Bulb -
Seat the quartz tube into the receptor at the bottom of the wet chamber.
The quartz tube will not go all the way down into the wet chamber unless the rounded end of the quartz
tube is seated in the receptor at the bottom of the wet chamber.
8.3 Removing the Bulb Cushion and O-Rings -
Place the black rubber sealing gasket all the way down
into the black plastic acorn nut, with the angled edge of the gasket facing downwardly when the nut is
installed on the sealing gland. DO NOT place the gasket on the quartz tube and then try to push the acorn
nut over the gasket. This will not allow the gasket to seal properly.
8.4
Install Acorn Nut -
Screw the acorn nut onto the threads of the sealing gland, being careful not
to cross thread the plastic nut. Tighten the acorn nut with a wrench, socket or crescent wrench. DO
NOT OVERTIGHTEN. This will crack the acorn nut and the rubber gasket will not seal the quartz tube
properly.
8.5
Check For Leaks -
Turn the circulation pump on and check the quartz tube seal for leaks. Correct
any leak found by carefully tightening the acorn nut ¼ turn. If the leak persists, remove the acorn nut and
bulb sealing gasket, inspect the bulb sealing gasket and replace if necessary. Follow previous procedures
for installing the acorn nut and seal and recheck the EUV unit for leaks again. Turn the circulation pump
off once you have confirmed that the quartz tube is not leaking.
9.0 Reinstalling The UV Bulb
– DO NOT TOUCH THE UV BULB GLASS WITH YOUR BARE HANDS. Oils
on your hands transfer to the bulb glass and cause hot spots on the bulb surface. If you have touched the bulb
with your bare hands, you must wipe the bulb glass off with Denatured Alcohol using a clean soft cotton cloth
before inserting the bulb back into the quartz tube.
9.1 Seating Bulb End Cushion -
Seat the bulb end cushion on the end of the bulb (the end that goes
down into the quartz tube first).
9.2
Installing O-Rings On Bulb End -
Place the two O’Rings around the top white porcelain bulb end
cap (where the electrical pins are located).
