STEP 4: Waste Header Installation
Place isoplast bolts through the flanges on the waste
header, then place flange gaskets on to the flanges
with the bolts. Install the waste header on to the
remaining valve flanges making sure to align the
flange holes with the bolts. It may be necessary to
turn the valves slightly to ensure a proper fit. Install
isoplast nuts. Snug the nuts to "hand tight", but do not
fully tighten.
STEP 5: 6" 2-way Valve Installation
Place isoplast bolts through the flange on the effluent
header, then place a flange gasket on to the flange.
Install the valve on to the flanges making sure to align
the flange holes with the bolts. The arrow on the
valve cover should be pointing away from the tank,
in the direction of the effluent flow. Install isoplast
nuts. Snug the nuts to "hand tight", but do not fully
tighten.
STEP 6: Sightglass Installation
Assemble the sightglass by threading the glass portion into
the threaded saddle on the spool. Be sure to use pipe
thread sealant tape on the threads. Place isoplast bolts
through flange on the waste header, then place a flange
gasket on to the flange. Install the sightglass assembly on
to the waste flange. Orient the glass portion so it will be
visible during operation. Install isoplast nuts and snug
them to "hand tight", but do not fully tighten.
