Step 2 — Dry Fit All Components <br /> A. Dry fit your tank riser to verify your measurements. After you have dry fitted all <br /> components and are satisfied with your measurements, apply an approved fuel resistant, non <br /> hardening thread sealant (pipe dope) to the NPT threads on both ends of the tank risers. <br /> Step 3— Install Tank Risers <br /> A. Install and torque the tank risers into the tank bungs. <br /> For Replacing Existing Phil-Tite 85000 series Spill Containers with 85000-1 series <br /> Spill Containers <br /> Step 1 - Determining The Correct Tank Riser length for Spill Container Installation <br /> A. Existing tank risers with NO M/F 4X4 riser adaptor installed. — Using a tape measure, <br /> measure from the top of your riser to finish grade and/or top of the manway cover. Record <br /> this measurement. For Fill spill containers this measurement should be 18-1/8" from the <br /> top of the riser to finish -grade. For Vapor Spill Containers this measurement should be 18" <br /> from top of riser to finish grade. If these measurements are less than the above <br /> measurements you must shorten your riser to meet these measure FEE) <br /> measurements allow for an M/F 4X4 Riser Adaptor to be installed o ank reser <br /> before the spill container is installed. If you are not installing an M/F 4X+'#q q 1' to <br /> your riser length. <br /> ENVI 'tP NT LHEALTH <br /> Remember, from finish grade to the top of the M/F 4X4 adaptor�n r ser <br /> should be 16-3/8"for Fill spill containers. See Figure 1. <br /> B. Existing tank risers with /F 4X4 riser adaptor installed — Using a tape measurer, measure <br /> from the top of the M/F 4X4 riser adaptor to finish grade and/or to the top of the stainless <br /> steel sleeve. Record this measurement. For Fill Spill Containers this measure must be <br /> greater than or equal to 16-3/8" (16 3/8" —20 1/8"), and for Vapor Spill Containers this <br /> measurement must be greater than or equal to 16 1/4" (16 1/4" —20"). <br /> C. If your existing riser is to long, there are several possible ways you can shorten them. <br /> Some possible methods are: <br /> 1) Remove the nipple that would have been installed prior to 2001 under the pre-EVR <br /> Installation Instructions and install a shorter nipple. Especially helpful for direct <br /> buried spill containers. <br /> 2) For multi-port systems, remove the existing riser(s) and install the correct length <br /> riser(s). Use an M-1600 riser support bracket to maintain alignment 16" on center <br /> between the fill and vapor riser. <br /> 3) For direct buried risers with no nipple and coupler you maybe able to excavate down <br /> to tank top using a 10" to 11" OD PVC pipe placed over the 4" riser. Then remove <br /> the backfill material as you lower the pipe down over the riser. When you have <br /> reached tank top remove the 4" riser and install the correct length 4" riser per <br /> following Steps 2 & 3. After you have installed the tank riser gradually remove the <br /> 10"— 11" OD PVC pipe as you back fill the space between the 4" riser and the 10— <br /> 11" OD PVC pipe. <br /> 2of8 <br />
