DANGER, WARNING, CAUTION and NOTE statements
Refers to conditions or hazards which could result in serious personal injury or death.
Refers to conditions or hazards which could result in personal injury.
Refers to conditions or hazards which could result in equipment or property damage.
Alerts you to facts or special instructions.
ALL DANGER, WARNING, AND CAUTION NOTICES MUST BE COMPLIED WITH IN FULL
Personal injury, property damage, equipment damage, or leakage due to escaping gas or bursting of
pressure containing parts may result if this regulator is over pressurized or installed where service
conditions could exceed the limits given in the specifications. To avoid such injury or damage, provide
pressure-relieving or limiting devices (as required by the appropriate code, regulation or standard) to
prevent service conditions from exceeding those limits.

2. INSTALLATION
2.1 Install the regulator/filter as close as possible to the instrument or tool it is to service.
2.2 Clean all pipelines to remove dirt and scale prior to installation.
Failures attributable to air supply contamination are not covered by the warranty.
This instrument vents to atmosphere. The use of gas other than air may create a
hazardous environment.
2.3 Install the regulator/filter so that the direction of flow is from the "IN" to "OUT" connec-
tion as marked on the body of the regulator/filter.

2.4 For best drainage, orient the drain valve so that it is at the lowest point on the drip well
housing. Positioning of the drain valve may be improved by rotating the drip well with
respect to the body.
2.5 The exhaust port should be kept free and unplugged. Position the regulator so that the
vent is at the lowest point possible, or provide additional protection to prevent contami-
nants from entering the regulator. Rotating the bonnet relative to the body may change
the vent hole orientation.
The Type 350/360SS has a low capacity internal relief that provides limited down stream protection
against over pressurization .
Nonrelieving version does not provide internal relief of excess pressure. To avoid exceeding outlet
pressure limits, a pressure-limiting device should be used.
2.6 Exhaust may be remotely vented by installing tubing to the 1/8" NPT port.
2.7 Apply pipe compound or sealing tape to the male pipe threads prior to installing
regulator/filter. Use caution to prevent the sealant from getting inside the regulator/filter.
3. OPERATION
3.1 Prior to turning on supply air, back off adjusting screw until there is no compression of
the range spring.
3.2 After applying the air supply, output pressure will be increased by rotating the adjust-
ment screw clockwise. Pressure can be decreased by turning counter clockwise.
3.3 Tighten locknut to maintain desired pressure setting.
4. MAINTENANCE & REPAIR
4.1 To remove condensate from the Type 350 and Type 370, slowly open drain valve by
turning clockwise and bleed accumulated liquid.
To avoid personal injury, property damage, or equipment damage caused by sudden release of pres-
sure or explosion of accumulated gas, do not attempt any maintenance or disassembly without first
isolating the regulator from system pressure and relieving all internal pressure from the regulator.
4.2 To clean filter element (Type 350 and Type 370)
4.2.1 Shut off supply pressure and relieve all internal pressure.
4.2.2 Drain condensate from drip well.
4.2.3 Remove four corner bolts from bottom of unit and remove drip well housing.
4.2.4 Remove filter retaining screw.
4.2.5 Remove filter retainer, filter o-ring seals and filter.
4.2.6 Clean parts and reassemble in reverse order.
4.3 To clean/replace pintle assembly
4.3.1 Follow steps 4.2.1 through 4.2.4.
4.3.2 Unscrew collar and remove.
4.3.3 Remove pintle spring and pintle. 1/4" NPT version may require needle nose pliers or push pintle stem from above by
removing bonnet and diaphragm assembly.
4.3.4 Clean/replace parts and reassemble in reverse order.

4.4 To clean/replace diap ragm assembly
4.4.1 Back out the adjusting screw until the spring is no longer compressed.
4.4.2 Remove the four bonnet screws and separate the bonnet from the body of the regulator. Remove the spring guide
and spring.
4.4.3 Remove the diaphragm assembly, clean or replace it as necessary and reassemble in reverse order. After placing
the diaphragm assembly on the body, push down the assembly to make sure that the pintle is seated properly and
strokes smoothly.
