 Values above based on achieving a 4-psi bubble tight 

seal using full-face chloroprene gasket on smooth and 
clean surfaces. Installing with fastener torques higher than 
suggested may reduce long-term sealing performance, 
and user does so at own risk.

This document contains the recommended procedures for installing, operating and maintaining the Series 5000 EPRV in 8, 10, 12 Sizes. Read and understand this document prior to 
installation, operation or maintenance of the EPRV. 

Secure EPRV in place with bolts and nuts supplied 
in the bolt kit. Use washers on the EPRV side of the 
bolted connection. Install hand-tight, then torque to 
recommended value using sequence shown in Section 
C4.

Remove nut and top washer from weight hanger 
bolt and set weights over weight hanger bolt. The set 
pressure of the EPRV with no weights installed is 1 ozsi 
and increases with the addition of weight plates.

Replace weight hanger nut and washer and tighten 
to 68 ft-lb.

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.

The transport lock can be left in the lowered position 
until it is required. To prepare the EPRV for transport 
proceed to section B1.
