suggested may reduce long-term sealing performance,
and user does so at own risk.

STANDARD INSTALLATION COMPLETE.
A2 (OPTIONAL) TRANSPORT LOCK
The transport lock can be installed on the 8" EPRV to
prevent damage to the device while the tank is being
transported in the vertical or horizontal position. The
transport lock holds the EPRV in a slightly open position.
This restricts entry of dust and contaminants into the
tank and prevents the internal pressure of the tank from
exceeding allowable limits during transport and if the
lock is accidentally left in place when the tank is placed in
service.
