SECTION 8: MAINTENANCE
Procedure
IMPORTANT: DO NOT Attempt to remove the QSM
Faceplate with the quartz sleeves assembled. ALL
lamps and quartz sleeves MUST be removed before
disassembling the QSM Faceplate from the UV vessel.
1. Unplug the Power Supply Enclosure from the
electrical outlet.
2. Redirect water flow from the vessel using isolation
valves and drain the vessel completely.
3. Remove UV lamp(s). See Page 17 for removal
instructions.
4. Remove quartz sleeve(s). See Page 18 removal
instructions.
5. With the vessel completely drained and the UV
lamps and quartz sleeves removed, loosen the QSM
Faceplate bolts in a diametric sequence. Continue
until all hardware is removed.
6. With fastening hardware removed, pull the QSM
Faceplate from the UV vessel.
7. Clean out the inside of the UV vessel using a mild
dish detergent and rinse thoroughly with clean
freshwater.
8. Thoroughly clean the mating surfaces of both the
QSM Faceplate and the UV Vessel.
9. Fit the QSM Faceplate Rubber Gasket onto the
alignment posts.
IMPORTANT: To properly align the QSM Faceplate,
set the #1 lamp position (as stamped on the faceplate,
next to the quartz sleeve module) to the 3 O' Clock
position when looking at the QSM Faceplate.
10. With the QSM Faceplate loosely aligned, push
the QSM Faceplate, with the rubber gasket, in
place onto the vessel. Next, loosely install (finger
tight) the supplied stainless steel hardware (bolts/
washers/nuts).
11. With the hardware loosely installed (finger tight)
fine tune the alignment of the #1 lamp position to
the 3 O' Clock position. To verify proper alignment
install the #1 quartz sleeve as outlined on Page 10.
The sleeve should go into its respective port on the
quartz sleeve coupler on the opposite end of the
unit without difficulty. If when installing the sleeve
you find it difficult to get the sleeve to engage in its
respective port on the quartz sleeve coupler this is
an indication that the #1 lamp position is not aligned
properly in the 3 O' Clock position. If this is the
case, rotate the QSM Faceplate either clockwise or
counterclockwise until the sleeve freely engages its
respective port on the quartz sleeve coupler.
12. Once the #1 lamp position is confirmed to be
properly aligned, establish uniform pressure over
the QSM Faceplate by tightening the bolts in 5
ft. • lb. increments in a diametrically opposed
(180°) sequence until the recommended torque is
obtained. See recommendations below.
Flange Bolt Torque Recommendations:
6.0" to 8.0" Flange = 40 ft. • lbs
10" Flange = 64 ft. • lbs.
