Instruction Manual

67C Series
4
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 away from air
intakes or any hazardous area. The vent
line or stack opening must be protected
against condensation or clogging.
BeforeinstallingaType67C,67CR,67CS,67CSR,
67CF, 67CFR, 67CFS or 67CFSR regulator, be
sure the installation complies with the following
installation guidelines:
1. Regulator operation within ratings does not
preclude the possibility of damage from debris
in the lines or from external sources. Regulators
should be inspected for damage periodically and
after any overpressure condition.
2. Onlypersonnelqualiedthroughtrainingand
experience should install, operate and maintain a
regulator.Makesurethatthereisnodamagetoor
foreignmaterialintheregulator.Alsoensurethatall
tubing and piping is free of debris.
3. InstalltheregulatorsothatowisfromtheINtothe
OUT connection as marked on the regulator body.
4. For best drainage, orient the drain valve (key 2) to
the lowest possible point on the dripwell (key 5). This
orientation may be improved by rotating the dripwell
with respect to the body (key 1).
5. Acloggedspringcaseventholemaycausethe
regulator to function improperly. To keep this
vent hole from being plugged (and to keep the
spring case from collecting moisture, corrosive
chemicals or other foreign material) orient the vent
Installation
Note
If the regulator is shipped mounted on
another unit, install that unit according
to the appropriate Instruction Manual.

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 is installed
where service conditions could exceed
the limits given in the Specications
section 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.
The internal relief valve of the
Type 67CR, 67CSR, 67CFR or 67CFSR
does not provide full overpressure
protection. The internal relief valve is
designed for minor seat leakage only. If
maximum inlet pressure to the regulator
exceeds maximum pressure ratings of
the downstream equipment or exceeds
maximum allowable outlet pressure of
the regulator, additional overpressure
protection is required.
