8. Using protective rubber gloves and eye wear use shower/
tub cleaner, CLR or equivalent, or a solution of white vinegar
and water to clean the outside of the quartz tube. Remove
the O-ring from the quartz tube. Fig. 14. If the inside of
the quartz tube is moist or needs cleaning use the same
cleaning method. The quartz tube must be completely dried
and clear of residue especially near the surface where the
o-ring rests before reassembly.
9. Inspect the quartz tube carefully for any cracks or
chips and replace the quartz tube if any are found.
NOTICE
Doing so can result in a leak and possible damage to
your UV unit. The O-ring must be replaced after cleaning
the quartz tube see page 16 for part number.
10. All components must be completely dry and
clean especially near the surface where the
o-ring rests. Never use any type of lube or
sealing agent. To reinstall the quartz tube place a
new O-ring 2 inches from the top of the outside of
the quartz tube Fig. 14. Gently lower the quartz tube
into the unit until the O-ring makes contact with the
top of the black threaded sealing sleeve. Fig. 15
Note: Use a Paramount O-ring seal only.
11. Then place the aluminum compression washer
and gasket on the quartz tube. Press down on the
aluminum compression washer with an even steady
pressure. Fig. 16 This will roll the O-ring into the area
between the inside of the black threaded sleeve and
the quartz tube. Lift aluminum washer and check to
make sure it is seated evenly around the circumference
of the quartz tube. Replace aluminum washer then
screw on the quartz sealing aluminum nut to hand tight
plus ½ turn.
12. Turn power on to the Ultra UV2 unit. Turn pump on to
check for leaks. Confirm that there are no leaks then
turn off pump and power off to the unit. Reinstall
lamps, spring clip and connect to ballast(s). Reattach
cover and turn power on to unit and turn pump on.
CAUTION
Do not use any other
O-ring at any time for
sealing the quartz tube.
Do not stand over the
unit when it is under
pressure or when the
pump is on.
