WARNING
Personal injury, property damage,
equipment damage, or leakage due to
escaping gas or bursting of pressure-
containing parts may result if this
regulator is overpressured or installed
where service conditions could exceed
the limits given in the Specications
section (page 2), or where conditions
exceed any ratings of the adjacent
piping or piping connections. To
avoid such injury or damage, provide
pressure-relieving or pressure-limiting
devices (as required by the appropriate
code, regulation, or standard) to
prevent service conditions from
exceeding those limits.
Additionally, physical damage to the
regulator could cause personal injury
or property damage due to escaping
gas. To avoid such injury or damage,
install the regulator in a safe and well
ventilated location.
Regulator operation within ratings does not preclude
the possibility of damage from debris in the lines
or from external sources. A regulator should be
inspected for damage periodically and after any
overpressure condition beyond the emergency outlet
pressure limit specied in the Specications section
(page 2). Key numbers referenced in this section are
shown in Figures 5, 6, and 7.
Note
If the regulator is shipped mounted on
another unit, install that unit according
to the appropriate instruction manual.
1. Only personnel qualied through training and
experience should install, operate, and maintain
a regulator. For a regulator that is shipped
separately, make sure there is no damage to, or
foreign material in the regulator. Also ensure that
all tubing and piping are free of debris.
2. The regulator may be installed in any position
as long as the ow through the body is in the
direction indicated by the arrow on the body.
Normal installation is with the spring case
barrel vertical above or below the diaphragm
case. However, when using a Type Y690A or
Y690AM regulator, for proper operation to achieve
the published capacities, the spring case barrel
should be installed pointed down as shown in
Figure 1. For complete actuator drainage of
Types Y690AH and Y690AHM, the regulator
should be installed as shown in Figure 3. If
continuous operation of the system is required
during inspection or maintenance, install a three-
valve bypass around the regulator.

WARNING
A regulator may vent some gas to
the atmosphere. In hazardous or
ammable gas service, vented gas may
accumulate and cause personal injury,
death, or property damage due to re or
explosion. Vent a regulator in hazardous
gas service to a remote, safe location
