1. Dig a hole and remove a 23" section of the discharge pipe (see Fig. 2). Clean both ends of the exposed pipe.

2. There are two sizes of pipe seals included with the ﬁ lter container. The larger seals are for SCH 40-4" PVC, and

the smaller seals are for SDR 35-4" PVC. Install the appropriate pipe seal in the basin so that the pipe will slide

in from the outside of the basin.

3. Cut and clean an 11" length of pipe from the 23" section of 4" pipe you removed from the discharge pipe. Ce-

ment a 4" coupling to one end of this pipe. The coupling will be used to reconnect the 11" length of pipe to the

existing pipe on the distribution side of the basin. Insert the pipe into outlet pipe seal, keeping the coupling on

the outside. Note: To ease installation, lubricate the seal with a mild soap solution such as dishwashing liquid.

4. Place 3" of sand or gravel in the hole. Place the basin in the hole, and adjust ﬁ ll as needed to line up the pipe

coming from the septic tank and the inlet hole on the basin. Insert the pipe coming from the septic tank into the

inlet of the basin. The pipe should extend into the basin approximately 1" (see Fig. 1).

5. Prepare the coupling and pipe for cementing, then push outward on the outlet pipe and cement the coupling

to the existing pipe. The pipe should extend into the basin approximately 3" (see Fig. 1). Note: After pipe is

installed, clean off any remaining lubricant. (See Step #3)

6. To attach the ﬁ lter (P/N 170-0078) to the outlet pipe, cement a 4" sanitary tee on to the outlet pipe with a 12"

length of 4" pipe cemented to the bottom opening of the sanitary tee (See Fig. 1). If using a Zoeller Filter (P/N

170-0144) remove the ﬁ lter from the sanitary tee. Cement the sanitary tee on to the pipe extending into the

outlet of the basin. If the piping is SDR 35 use the reducer supplied with the ﬁ lter. Slide the ﬁ lter back into the

sanitary tee.

7. Attach the 12" extension riser to the basin using the supplied foam gasket and bolts. Apply silicone caulking

over the bolt and washer after installed. (Optional 6" and 12" extension risers are available to be added to the

12" extension as needed.) (See Front.)

8. Attach the cover to the extension using the supplied foam gasket and bolts.

9. Backﬁ ll to the top of the extension.
