Installation Guidelines for the P.A.P.A.
|
The P.A.P.A. unit can be installed vertically onto the stack by using either one 90° bend, or two 45° bends, so it uses less space.
|
The P.A.P.A. unit is pushed into the pipe using the synthetic rubber connector that fits into 75 mm and 110 mm pipes.
|
The P.A.P.A. units can be installed as a standalone fitting. The configuration of a P.A.P.A. unit installed without a Maxi-Vent should be used to solve problems on floors where no extra ventilation is required.
|
|
|
|
When installed without a Maxi-Vent, the P.A.P.A. unit may be positioned horizontally.
|
|
|
|
The P.A.P.A. units can be installed in series, which will add additional protection.
This is recommended at the base of the stack, or at any point where heavy use is expected, for example sports stadiums, etc.
The P.A.P.A. units have been designed so they can be built in series, which enables them to solve - or prevent - problems in areas of large positive transients. Up to a maximum of four units can be placed in series.

|
It is recommended that the P.A.P.A. units be installed with a Maxi-Vent on top.
The cap of the P.A.P.A. unit should be removed and the Maxi-Vent pushed onto the unit using the connector. This will turn the P.A.P.A. unit into a positive and negative protection device. Distributed venting will limit the extent of the final pressure because the path of the air intake will be shorter.

|
|
When installed with a Maxi-Vent on top, the P.A.P.A. unit must be positioned vertically.
Note: The P.A.P.A. unit does not solve the problem of a slow buildup of pressure, a sustained positive pressure originating from deposits blocking the pipes, the blockage of a public sewer, an overloaded septic tank, etc.
