Inspection Points (continued)
Inspection Points – Recirculation/
Blend Tank
Complete all of the inspections and checks described in the “Inspection
Points – Tanks and Basins” section of this manual and then verify that the
inspection points below are as follows:
1.
Recirc valve:
Verify the recirc valve is set so that the maximum
water level in the tank matches the maximum liquid level as
specified by the engineer. If the maximum liquid level is not on the
plans, a general rule is to set it at 80% of the tank depth for straight-
walled tanks or 80% of tank volume for curve-walled tanks.
2.
Stinger length:
Adjust the length of the recirc valve stinger based
on installation instructions.
a. Calculate the necessary
stinger length adjustment
using the equation (A+B)-16
"
or (A+B)-406 mm, where A
is the distance from the MM
valve invert to the top of the
tank and B is the distance
from the top of the tank to the
100% discharge level. If the
stinger needs to be lengthened
to near or beyond the length
of the cage, the cage will also
need lengthening.
b. Stinger Adjustment Dimensions:
• A = Distance from invert of MM valve to top of tank
• B = Distance from top of tank to the liquid level where 100%
bypass is desired, typically 80% of the tank’s volume
• C = Standard cage length: MM4 49 inches (1245 mm), fits
stingers up to 36 inches (914 mm); MM6 57 inches (1448
mm), fits stingers up to 40 inches (1016 mm)
• D = Middle of ball (at the 100% discharge level)
NOTE:
There should be a minimum of 9 inches (229 mm) from the
normal liquid level to the “RO” float.

Filter Pods
Your system may include AX100 filter pods (shown) or AX20 filter pods.
For AX20 inspection points, see the residential
Installation Manual
and
residential
AdvanTex O&M Manual,
provided in Appendix B.
1.
Installation
inspection:
Verify
the AX100 pod
has been properly
installed. Improper
installation is
usually indicated by
the conditions listed
below:
• Sidewall bowing — Check for any sidewall bowing in the pod. The
bowing may cause excessive spacing between media sheets. If
the spacing between the media sheets exceeds ½-inch (13 mm),
cut the fiberglass rods for the correct media sheet spacing.
• Lid misalignment — Lid bolts will only go into the holes if the lid
is lifted slightly and the bolts are partially inserted prior to closing
the lid.
2.
Manifolds and Laterals:
Flush the manifolds and laterals. See the
AX100 Treatment Systems Installation Manual
and
Field Maintenance
Report Form
in
Appendix B for more information.
For proper operation after flushing the manifolds and laterals, turn
the ball valves to their correct positions and turn the spray nozzle
turbines to point down.
3.
System Pressure:
Verify the pressure
gauge is set to zero. If it is not, open
the seal at the top and let the pressure
equalize with atmosphere. Install the
pressure gauge, turn on the recirc
pumps, and set to 3.0 psi (20.6 kPa).
NOTE:
On systems plumbed in parallel, adjust the pressure in
all three pods at the same time to 3.0 psi (20.6 kPa) using the
gate valve on the pod manifold.
4.
Pod drainage:
Verify that the pod drains easily. If the pod does not
drain, check to see if the shipping plug has been removed from the
pod outlet.
5.
Lid bolt installation:
When you have finished inspecting all pods,
remove the pressure gauge and secure the lids on the pods with the
included lid bolts.
