Type EZR

When using an inlet strainer (key 23), do not use
the shim (key 23) and vise versa.

When installing a Type EZR trim package in an
existing E-body, make sure flow is up through the
center of the cage and down through the cage
slots. In some cases, correct flow path is
achieved by removing the body from the line and
turning it around. If this is done, change the flow
arrow to indicate the correct direction. Damage
may result if flow is not in the correct direction.
After assembly, check the regulator for shutoff
and leakage to atmosphere.

Note

It is important that the regulator be installed so that
the vent hole in the spring case is unobstructed at all
times.  For outdoor installations, the regulator should
be located away from vehicular traffic and positioned
so that water, ice, and other foreign materials cannot
enter the spring case through the vent.  Avoid placing
the regulator beneath eaves or downspouts, and be
sure it is above the probable snow level.

Overpressure Protection

The recommended pressure limitations are stamped on
the regulator nameplate.  Some type of overpressure
protection is needed if the actual inlet pressure exceeds the
maximum operating outlet pressure rating.  Overpressure
protection should also be provided if the regulator inlet
pressure is greater than the safe working pressure of the
downstream equipment.

Regulator operation below the maximum pressure limitations
does not preclude the possibility of damage from external
sources or debris in the line.  The regulator should be inspected
for damage after any overpressure condition.

Startup

The regulator is factory set at approximately the midpoint of
the spring range or the pressure requested, so an initial
adjustment may be required to give the desired results.   With
proper installation completed and relief valves properly
adjusted, slowly open the upstream and downstream shutoff
valves.

Adjustment

To change the outlet pressure, remove the closing cap or
loosen the locknut and turn the adjusting screw clockwise
to increase outlet pressure or counterclockwise to decrease
pressure.  Monitor the outlet pressure with a test gauge
during the adjustment.  Replace the closing cap or tighten
the locknut to maintain the desired setting.

Taking Out of Service (Shutdown)

To avoid personal injury resulting from sudden
release of pressure, isolate the regulator from all
pressure before attempting disassembly.

Make sure to use a Type EZR bonnet. The Type
EZR bonnet is NOT interchangeable with other
Fisher E-body bonnets. Installing an improper
bonnet can result in stem assembly breakage
and unit failure. The bonnet can be identified by
the EZR markings on the top.
