2.5. Vent Line Installation
Use only 2”, 3” or 4” Schedule 40 PVC or equivalent pipe
for vent line. Follow all applicable AARST, EPA, and/or
State Standards for Radon or VOC venting.
1.
Connect vent line to 2” socket elbow on the rear of the
system (figure 9). Use PVC cement in a fashion that ensures
no leakage will occur. Note: A rubber coupling permitting
disconnection of the system from the vent line for future
maintenance is provided beneath the cover.
2.
The vent line must be mounted in a fashion that allows the
system to exhaust above the level of the roof (Figure 10).
3.
The vent must be pitched back towards the system to ensure
that any condensation runs back into the unit. If an optional
inline auxiliary fan is used, recommendations regarding
pipe pitch in the fan installation instructions must be strictly
adhered to.
4.
If an optional auxiliary fan is used then the fan must be
wired to the system electrical box, connections as shown in
the Electrical Schematic (Figure 8). This will ensure that the
fan operates only when required by the system. The “red”
lead is the live feed from the Aeration System to the Fan.
Warning: Do Not connect any of the Fan Leads to a separate power
source. This will cause the Aeration System to Malfunction
5.
Install weather cap on top of the vent line. This cap should
not restrict air flow and must prevent rain, snow and other
contaminants from entering the vent line.
Failure to install a proper vent line may cause
contamination of the water, outgassing of
contaminants into the building, limit system
performance and/or cause the system to
overflow.
NOTE: The Manufacturer has found that vent lines less than 250
equivalent linear feet do not cause a decrease in contaminant
removal percentages. 90° Bend = 15 Equiv. Linear Ft ; 45° Bend =
7 Equiv. Linear Ft. An inline auxiliary fan is recommended if the
vent line exceeds 250 equivalent linear feet.
