SECTION I

I. DESCRIPTION AND SCOPE

These regulators are designed for air service only. Maximum allowable inlet pressure is 290 psi. Operating temperatures

are -20

to 180

F. The 5300P has low capacity internal relief which provides very limited down stream over pressure

protection. Note: Non-relieving version does not provide internal relief. To avoid exceeding outlet pressure limits in ser-

vice, a pressure-relieving or pressure-limiting device should be provided.

SECTION II

II. INSTALLATION

Install the regulator as close as possible to the instrument or tool it is to service. Clean all pipelines to remove dirt and

scale prior to installation. The words "IN" and "OUT" are cast into the body to indicate the direction of ﬂ ow. For best ﬁ lter

drainage orient the drain valve so that it is at the lowest point on the drip well housing. The exhaust port should be kept

free and unplugged. Position the regulator so the vent is at the lowest point possible, or provide additional protection

to prevent contaminants from entering the regulator. Rotating the bonnet relative to the body may change the vent hole

orientation. Exhaust may be remotely vented by installing tubing to the 1/8" NPT port. Apply pipe compound or sealing

tape to the male pipe threads prior to installing regulator. Use caution to prevent the sealant from getting inside the

regulator.

SECTION III

III. PRINCIPLE OF OPERATION

Prior to turning on supply air, back off adjusting screw until there is no compression of the range spring. After turning

supply pressure on, turn the adjusting screw clockwise to increase outlet pressure. Tighten locknut to maintain desired

pressure setting.

SECTION IV

IV. MAINTENANCE

1. To remove condensate, slowly open drain valve and bleed accumulated liquid.

2. To clean ﬁ lter element

a. Shut off supply air.

b. Drain condensate.

c. Remove four corner bolts from bottom of unit.

d. Remove dripwell housing and ﬁ lter.

e. Clean parts and reassemble in reverse order.
