EPRV-C.DOC 8/23/2013
Vent Installation
Prior to installation, remove the unit from its crate and discard any protective coverings.
Below is a list of instructions that are recommended for the installation of an Enardo
emergency relief valve. Both the EPRV and EPRV-V can be installed in the same
manner.
1.
The weight loaded Emergency Pressure Relief Vent (EPRV) and Emergency Pressure Relief
Vent with Vacuum (EPRV-V) should be installed on flange bolt patterns that match that of
the vent itself. The attachment flange base should be a level surface.
2.
Carefully, remove the EPRV or EPRV-V from its crating (see warning above). Keep in mind
that the seal portion of the vents is somewhat delicate, therefore protect this surface while
transporting the unit accordingly.
3.
With an appropriate gasket placed on the level attachment flange, center the vent into place.
4.
Insert the appropriate number of bolts and make sure the vent is fastened securely. Installed
bolts should be clear of the lid assembly when it is in the full open position.
5.
Inspect the now installed unit for items that would keep it from working properly. The
sealing area should be free of any debris that would cause leakage. The arm of the vent
should be able to fully open.
*****WARNING*****
The EPRV is shipped with its lid held partially open. The lid
assembly has attached weights and is heavy. Use caution when
removing the shipping blocks and metal bands to avoid injury to
fingers and hands.
Calibration weights must be removed before installing the EPRV onto
the tank. Failure to remove the weights could result in personal injury
and product damage. The weights should be reinstalled to their
original location once the EPRV is securely mounted to the tank. A
roll pin has been installed in the weight arm for weight location
purposes. When the weights are located in this manner the factory
setting will be established.
