• Check effluent piping grooved coupling connection to make sure it has not
become loose during shipping. If the coupling bolts have become loose, tighten
them.
• Make sure automatic air relief is attached properly.
This mechanism assists in bleeding off air, which may
become trapped in the top of the tank. It is located on
the effluent pipe near the top of the tank, and should
be installed with the screen pointing up.
2.6 Pressure Test System
WARNING: Filters should never be tested or subjected to air or
gas under pressure. All gases are compressible, and under pressure
create a danger. Severe bodily injury or property damage could occur if
the filter is subjected to air or gas pressure.
CAUTION: DO NOT exceed the maximum working pressure of the
vessel (50 psi) during testing or operation.
NOTE: DO NOT install media prior to pressure testing the system.
• Install the manway cover (See section 4.3) and check that all piping connections,
manual air relief cap, and media drain cap are tight.
• Flood the system with water. Make sure to bleed all air out of the tanks using the
manual air relief cap.
• Pressurize the system. Caution: DO NOT exceed 50 psi.
• Inspect all installed filtration equipment, focusing on solvent welded connections,
mechanical connections, and all tank penetrations.
NOTE: In the unlikely event that a leak is attributed to the vessel, consult
the equipment supplier before proceeding with any tank repairs.
Unauthorized repair attempts may void the factory warranty.
• Drain the tank(s). It is important to read section (4.2) for proper instructions.
• Make repairs if necessary. Before proceeding further, all repairs should be made at
this time.
NOTE: Do not perform the following step until the system is pressure
tested and all leaks are repaired (See Start-Up and Installation).
