Installation Instructions

FOR A ONE-PART SNOUT^®

1. Select the Snout Oil & Debris Separator of size and configuration to fit application.

2. Center the Snout directly over the outlet pipe so that the entire pipe is covered and the lower edge of the hood is at least 1/2 the pipe diameter below the lowest inside point of the pipe (deeper is even better).

3. Drill equally spaced 7/16" holes through the Snout flange.

4. Mark and drill catch basin and install the tamp-in lead anchors.

Drill a 3/4"hole into the base material to the required depth (approximately 1-1/4" deep.)
Blow the hole clean of dust and other material.
Insert the anchor into the hole. Narrow end of cone must point out, lead shield slides over cone.
Position the setting tool or a 9/16 socket against the anchor outer cone. (The outer rim of the tool or socket should seat onto the lead shield rim.) Set the anchor by driving the lead sleeve over the cone using several sharp hammer blows. Be sure the anchor is at the required embedment depth (flush or slightly below face of concrete)

5. Attach the vent pipe adapter in the predrilled hole in the top of the Snout using the 2 flat O ring gaskets and PVC lock-nut supplied in kit. Install with the female pipe adapter up and a washer on each side of the Snout shell. Tighten lock-nut hand tight.

6. Remove PSA backing and with firm pressure, attach gasket strip to back of Snout flange, trim excess and save.

7. Attach the Snout to the catch basin wall with 3/8" diameter stainless steel bolts. Do not over tighten; 10-15 foot pounds should be sufficient.

8. Cut the anti-siphon vent stack to length and attach to hood at pipe adapter with PVC cement.

9. Attach 90 degree elbow to vent stack with PVC cement. Ensure that the elbow opening is accessible for maintenance and inspection.

Snout Installation Kit Items included with each Snout (Number and sizes will vary with size of Snout)

( ) 3/8"expansion anchor assemblies (anchors, stainless bolts & stainless washers)
(1) 1" or 2" female pipe adapter
(2) Neoprene O rings
(1) PVC lock-nut
( ) PSA backed gasket strip(s)
(1) 1" or 2" diameter 12" length PVC pipe
(1) 90 degree elbow

EXTRA INSTALLATION INSTRUCTIONS FOR A TWO-PART SNOUT

Larger size Snouts are shipped knocked down in two parts. Therefore it will be necessary to site assemble the two halves. Use the supplied gasket(s) to make the connections between the 2 parts of the Snout and the Snout & the wall of the structure. Overlap intersecting gaskets approximately 1" to insure a good seal.

1. Stand base section upright & install one of the PSA-backed gaskets to the top connecting flange. Trim excess and save.
2. Place dome part on the base section and temporarily clamp together to align.
3. Locate evenly spaced bolt locations along connecting flange.
4. Drill holes to receive the 1" x 3/8" SS bolts, nuts and washers.
5. Remove clamps.
6. Bolt the dome to the base after lowering the two halves into the structure.

Continue with instructions above starting with step #1 for one-part Snout installation.

2-Part Snout Installation Kit Items included with each Snout (Number and sizes will vary with size of Snout)
