Pentair BIOSHIELD CLP41A6-XN Installation And User Manual page 37

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 11. 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 (180º) sequence until the recommended torque is obtained. See
recommendations below.
Flange Bolt Torque Recommendations:
0.5" to 1.5" Flange = 12 ft. • lbs.
2.0" to 4.0" Flange = 25 ft. • lbs.
5.0" Flange = 30 ft. • lbs.
6.0" to 8.0" Flange = 40 ft. • lbs.
10" Flange = 64 ft. • lbs.
12" Flange = 95 ft. • lbs.
14" to 24" Flange = 40 ft. • lbs.
