High sound levels may be experienced during "try
lever" test. Wear proper safety equipment and exercise extreme
care! Test at or near maximum operating pressure by holding the
test lever fully open for at least 5 seconds to flush the valve seat
free of sediment and debris. Then release lever and permit the
valve to snap shut.
If lift lever does not activate, or there is no evidence of
discharge, turn off equipment immediately and contact a licensed
contractor or qualified service personnel.

To achieve topmost performance and maximum service life, it
is necessary to maintain a proper pressure margin between the
set pressure of the safety valve and the equipment's operating
pressure.
The minimum required operating pressure margin for this type of safety
valve is 10% of the safety valve set pressure, but not less than 7
PSI.

use the test lever as a lifting device during installation.
8) Use pipe compound sparingly, or tape, on external threads only.
5) Insure that all connections, including the valve inlet, are clean
and free from any foreign material.

pressure and temperatures involved. Gaskets must be sized to fully
clear the valve inlet and outlet openings.

Under no circumstances should there be flow restriction or valve
of any type between the safety valve and the pressure vessel.

properly connected to valve outlet and arranged to contain and
safely dispose of boiler discharge (see "Installation Instructions").
Under normal operating conditions a "try lever test" should be
performed every two months. Under severe service conditions, or
if corrosion and/or deposits are noticed within the valve body,
testing must be performed more often. A "try lever test" should
also be performed at the end of any non-service period.

This quality Conbraco safety valve, along with proper installation,
use, and maintenance, will provide many years of reliable service
and protection against excessive pressure build-up of steam, air,
water or, nonhazardous gas. Use of this valve for any other purpose
or media places all responsibility upon the user. Before installing
valve, or operating equipment to which it is installed, read all
instructions carefully. Always wear proper safety equipment.
2) The lb/hr, GPM or CFM rating of this valve must equal or exceed
that of the equipment to which it is installed.
