Installation and Operation Precautions

• Mount the shell on horizontal members at span “S” using compliant vessel supports; tighten hold down straps just snug.
• Provide overpressure protection for the vessel set at not more than 105% of design pressure.
• Inspect end closures regularly; replace deteriorated components and correct causes of corrosion.
• Do not make rigid piping connections to ports or clamp the vessel in any way that resists the growth of the fiberglass shell under pressure.
• Do not hang piping manifolds from ports or use the vessel to support other components.
• Do not operate the vessel without permeate ports internally connected with a complete set of elements and interconnecting hardware.
• Do not overtighten the connection to the permeate port (hand-tighten plus one-quarter turn, then check for leaks).
• Do not tolerate leaks or allow end closures to be routinely wetted.
• Do not pressurize the vessel until double-checking to verify that the retaining ring is completely inside the groove.
• Do not work on any component until first verifying that pressure is relieved from the vessel.

Ordering

• Provide membrane brand and specific model number when ordering.
• For optional materials or features not listed, consult the factory for pricing and availability.
